KOMPAKTNI SISTEM ZA OBDELAVO SANITARNE ODPADNE VODE IN NJENO PONOVNO UPORABO ZA SPIRANJE WC ŠKOLJKECOMPACT SYSTEM FOR THE TREATMENT OF SANITARY WASTE WATER AND ITS RE-USE FOR Flushing the toilet bowl
Predmet izuma je kompaktni reaktorski sistem za obdelavo sanitarne odpadne vode s kombinacijo intenzivnega biološkega postopka za odstranjevanje organskih snovi in postopka uravnavanja koncentracije mikroorganizmov z dezinfekcijo z UV lučjo. Obdelana sanitarna voda se ponovno uporabi za spiranje WC školjke.The subject of the invention is a compact reactor system for the treatment of sanitary wastewater, with a combination of an intensive biological process for the removal of organic matter and a process for regulating the concentration of microorganisms by disinfection with UV light. The treated hot water is reused to flush the toilet bowl.
Problem, ki ga rešuje izumThe problem solved by the invention
Pomanjkanje neoporečne pitne vode predstavlja povsod po svetu težavo, ki se potencira z rastjo prebivalstva in višjo stopnjo urbanizacije. Hkrati pa velika večina gospodinjstev porablja dnevno velike količine pitne vode tudi za namene (npr. za splakovanje WC školjke), kjer takšna kakovost vode ni potrebna. Predmetni izum, ki omogoča ponovno uporabo onesnažene sanitarne vode, predstavlja rešitev za zmanjšanje porabe pitne vode v gospodinjstvih. Predlagana rešitev je zaradi svoje kompaktne izvedbe primerna tudi za manjše stanovanjske enote.Lack of unrivaled drinking water is a problem everywhere, compounded by population growth and higher urbanization. At the same time, the vast majority of households also consume large quantities of drinking water daily for purposes (such as flushing the toilet) where such water quality is not required. The present invention, which enables the re-use of contaminated hot water, is a solution for reducing the consumption of drinking water in households. Due to its compact design, the proposed solution is also suitable for smaller residential units.
Stanje tehnikeThe state of the art
Do sedaj poznani patentirani kompaktni (hišni) sistemi, ki omogočajo ponovno uporabo sanitarne odpadne vode za spiranje WC školjke, večinoma uporabljajo neobdelano sanitarno odpadno vodo (CN201228372, CN201190305, CN201125422), pri patentu CN195192092 je omenjena biološka obdelava sanitarne odpadne vode v posebni filtrski enoti. Odpadna sanitarna voda, ki nastane po tuširanju ali kopanju v gospodinjstvih in javnih zgradbah, vsebuje raztopljene organske snovi (ostanki mila in preparati za osebno nego), trdne delce in mikroorganizme. V rezervoarjih, kjer se zbira sanitarna odpadna voda, začnejo mikroorganizmi razgrajevati organske snovi, pri čemer se nenadzorovano množijo, kar lahko povzroči smrad ali celo zamaši cevi v splakovalniku ali WC školjki. Po izumu smo ta problem rešili tako, da sistem za obdelavo sanitarne odpadne vode vključuje intenzivni biološki proces za odstranjevanje raztopljenih organskih snovi in proces deaktivacije mikroorganizmov z UV svetlobo določene valovne dolžine.The patented compact (house) systems known so far that allow the reuse of sanitary wastewater to flush the toilet bowl mainly use untreated sanitary wastewater (CN201228372, CN201190305, CN201125422), with reference to patent CN195192092 the biological treatment of sanitary wastewater in a special filter unit . Waste water generated by showering or bathing in households and public buildings contains dissolved organic substances (soap residues and personal care preparations), solids and micro-organisms. In reservoirs where sanitary wastewater is collected, microorganisms begin to decompose organic matter, multiplying uncontrollably, which can cause the stench or even clog the pipes in the flushing cistern or toilet bowl. According to the invention, this problem has been solved by the fact that the sanitary wastewater treatment system includes an intensive biological process for the removal of dissolved organic matter and the deactivation of microorganisms with UV light of a certain wavelength.
Opis izuma in izvedbeni primerDescription of the invention and embodiment
Izum bo opisan na osnovi izvedbenega primera in slike, ki prikazuje:The invention will be described on the basis of an embodiment and an illustration showing:
Slika 1. Kompaktni sistem za obdelavo sanitarne odpadne vodeFigure 1. Compact sanitary wastewater treatment system
Kompaktni sistem za obdelavo sanitarne vode je prikazan na sliki 1. Sestavljen je iz rezervoarja 1, vtočnega dela la rezervoarja 1, aktivnega dela lb rezervoarja 1, reaktorskega modula lc, pokončne pregrade ld, modula za dezinfekcijo 2, nivojskega senzorja 3, elektromagnetnega ventila za odvzem vode 4, elektromagnetnega ventila za dotok vode iz vodovodnega omrežja 5, elektromagnetnega ventila s časovnim regulatorjem 6, odprtega preliva 7 in odduha 8. Pri kompaktnem sistemu za obdelavo sanitarne odpadne vode z namenom njene ponovne uporabe, je uporabljen intenziven biološki proces za odstranjevanje organskih snovi, ki so prisotne v odpadni vodi. Biološki proces poteka z mikroorganizmi, pritrjenimi na nosilni material. Delovanje sistema temelji na principu občasnega ali stalnega prisilnega kroženja vode skozi aktivni del lb rezervoarja 1 z reaktorskim modulom lc in modulom za dezinfekcijo 2.The compact sanitary water treatment system is shown in Figure 1. It consists of reservoir 1, inflow part la of reservoir 1, active part lb of reservoir 1, reactor module lc, upright barrier ld, disinfection module 2, level sensor 3, solenoid valve for withdrawal of water 4, solenoid valve for water supply from water supply network 5, solenoid valve with time controller 6, open spillway 7 and vent 8. The compact system for treatment of sanitary wastewater for its reuse uses an intensive biological process for organic removal. substances present in waste water. The biological process is carried out with microorganisms attached to the carrier material. The operation of the system is based on the principle of periodic or continuous forced circulation of water through the active part 1b of reservoir 1 with the reactor module lc and the disinfection module 2.
Sanitarna odpadna voda, s koncentracijo organskih snovi izraženo kot KPK v območju od 10-250 mg/l, se obdeluje v rezervoarju 1, ki hkrati služi kot nadometni ali podometni splakovalnik. Rezervoar 1 je izveden v obliki posode s poševnim dnom s kotom nagiba 5 - 20°, volumna od 50 - 200 litrov, izdelane iz plastičnega materiala, ki se uporablja za klasične sanitarne splakovalnike (kotličke). Rezervoar 1 je opremljen s pokončno pregrado ld, ki deli rezervoar 1 na dva dela v volumskem razmerju 1: 5, pri čemer predstavlja manjši volumski del vtočni del la, večji volumski del pa aktivni del lb rezervoarja 1. S pokončno pregrado ld je v zgornjem delu rezervoarja 1 preprečen direktni stik med vodo, ki se zadržuje v aktivnem delu lb rezervoarja 1 in vodo, ki doteka v rezervoar 1. V spodnjem delu rezervoarja 1 znaša razdalja med spodnjim robom pregrade ld in dnom rezervoarja 1 od 4 do 10 cm. Dotok vode (sanitarne odpadne vode, občrpavane vode in vodovodne vode), je izveden v vtočnem delu la rezervoarja 1, torej delu za pregrado ld z manjšim volumnom, pri čemer se voda dovaja pod gladino vode, zadrževane v rezervoarju 1. V spodnji del aktivnega dela lb rezervoarja 1, torej v delu za pregrado ld z večjim volumnom, je vstavljen reaktorski modul lc v obliki košare s stenami iz mreže iz nerjavnega materiala, ki je napolnjen z nosilcem mikroorganizmov. Kot nosilni material je uporabljen dobro definiran industrijski izdelek s poznanimi mehanskimi in kemijskimi lastnostmi. Nosilec temelji na ekspandiranem polimeru v obliki okroglih lističev s trgovskim imenom Mutag BioChip (Umvvelttechnologie AG, Nemčija), kije močno porozen in ima zato zelo veliko specifično površino 3.000 m2/m3. Slednje omogoča, da je v majhnem volumnu reaktorskega modula lc, napolnjenem z nosilnim materialom, dosežena visoka koncentracija mikroorganizmov, ki so naseljeni in se množijo v porah nosilca. Volumen reaktorskega modula lc znaša % volumna celotnega rezervoarja 1, reaktorski modul lc pa je napolnjen z nosilcem do A tako, da lahko delci nosilca plavajo v omejenem volumnu reaktorskega modula lc. Rezervoar 1 je v zgornjem delu opremljen z odprtim prelivom 7, ki omogoča vzdrževanje gladine vode v rezervoarju 1 in odduhom 8, preko katerega se rezervoar 1 odzračuje.Sanitary wastewater, with an organic matter concentration expressed as COD in the range of 10-250 mg / l, is treated in reservoir 1, which simultaneously serves as a surface or surface flusher. Tank 1 is made in the form of a sloping tank with an angle of inclination of 5 - 20 °, volume of 50 - 200 liters, made of plastic material used for classic sanitary flushing cisterns (kettles). Tank 1 is provided with an upright barrier ld, which divides the tank 1 into two portions in a volume ratio of 1: 5, with the smaller volume portion representing the inflow portion la and the larger volume portion the active portion lb of tank 1. With the upstream barrier ld being in the upper part of tank 1 is prevented from direct contact between water retained in the active part lb of tank 1 and water flowing into tank 1. In the lower part of tank 1, the distance between the bottom edge of barrier ld and the bottom of tank 1 is 4 to 10 cm. Water inlet (sanitary wastewater, abstracted water and tap water) is effected in the inlet part 1 of reservoir 1, ie the partition partition ld with a smaller volume, the water being fed below the water level retained in reservoir 1. Into the lower part of the active part 1b of reservoir 1, that is to say, in the bulk partition ld part, a reactor module lc is inserted in the form of a basket made of stainless steel mesh filled with a carrier of microorganisms. A well-defined industrial product with known mechanical and chemical properties is used as a carrier material. The carrier is based on an expanded round-shaped polymer called Mutag BioChip (Umvvelttechnologie AG, Germany), which is highly porous and therefore has a very large specific surface area of 3,000 m 2 / m 3 . The latter allows a high concentration of microorganisms to be reached and multiply in the pores of the carrier in a small volume of the reactor module lc filled with the carrier material. The volume of the reactor module lc is% of the volume of the entire tank 1, and the reactor module lc is filled with the carrier to A so that the carrier particles can float in the limited volume of the reactor module lc. The tank 1 is provided in the upper part with an open overflow 7, which allows the water level in the tank 1 to be maintained and the vent 8 through which the tank 1 is vented.
Na zunanji steni rezervoarja 1 je nameščen modul za dezinfekcijo 2 z nizkotlačno UV žarnico z močjo 15-20 W, ki oddaja UV svetlobo v območju 180-260 nm in črpalko, ki omogoča prisilno kroženje vode med aktivnim delom lb rezervoarja 1 z reaktorskim modulom lc in modulom za dezinfekcijo 2, pri čemer je odvzem vode izveden v aktivnem delu lb rezervoarja 1 v višini od 1 - 3 cm nad zgornjim robom reaktorskega modula lc. Pri črpanju vode skozi modul za dezinfekcijo 2 se deaktivirajo mikroorganizmi, ki so prisotni v vodi. Ker so aktivni mikroorganizmi imobilizirani v reaktorskem modulu lc z nosilcem, ta pa zadrži in delno razgradi tudi mikroorganizme, ki pridejo v rezervoar 1 s sanitarno odpadno vodo, je na ta način v vodi, ki kroži v sistemu, prisotna le nizka koncentracija dispergiranih aktivnih mikroorganizmov. Zato se lahko za dezinfekcijo uporabi vir UV svetlobe z nižjo intenziteto oziroma nizko porabo energije.On the outer wall of reservoir 1 is a disinfection module 2 with a low-pressure UV lamp of 15-20 W power, which emits UV light in the range of 180-260 nm and a pump that allows forced circulation of water during the active part of the reservoir 1 lb with the reactor module lc and a disinfection module 2, wherein the water abstraction is performed in the active portion 1b of reservoir 1 1 to 3 cm above the upper edge of the reactor module lc. When pumping water through the disinfection module 2, the microorganisms present in the water are deactivated. Since the active microorganisms are immobilized in the reactor module lc by the carrier, which retains and partially decomposes the microorganisms that enter sanitary wastewater reservoir 1, thus only a low concentration of dispersed active microorganisms is present in the circulating water in the system. . Therefore, a lower intensity or low energy consumption UV light source can be used for disinfection.
Splakovanje WC školjke z obdelano vodo iz rezervoarja 1 poteka preko elektromagnetnega ventila za odvzem vode 4 povezanega z nivojskim senzorjem 3, ki omogoča izbiro definirane količine porabljene vode za eno splakovanje. Elektromagnetni ventil za odvzem vode 4 je nameščen na vtočnem delu rezervoarja 1 tako, da se odvzem vode iz rezervoarja 1 vrši na višini 4 cm nad zgornjim robom reaktorskega modula lc. Tako lahko nivo vode v rezervoarju pade le do višine, pri kateri je reaktorski modul lc še potopljen v vodi pri vseh pogojih delovanja. Na ta način preprečimo nastajanje smradu v rezervoarju 1 in njegovo širjenje v okolico. Rezervoar 1 se s pomočjo zunanje črpalke ob ponovnem tuširanju ali kopanju polni s sanitarno odpadno vodo, pri čemer odvečna voda preko odprtega preliva 7 na vrhu vtočnega dela la rezervoarja 1 izteka v kanalizacijski sistem.The flushing of the toilet bowl with treated water from the reservoir 1 is via a solenoid valve for water withdrawal 4 connected to a level sensor 3, which allows the selection of a defined amount of used water for one flush. The solenoid solenoid valve 4 is positioned at the inlet portion of the reservoir 1 so that water is withdrawn from the reservoir 1 at a height of 4 cm above the upper edge of the reactor module lc. Thus, the water level in the tank can only fall to a height at which the reactor module lc is still submerged in water under all operating conditions. This prevents the formation of odor in tank 1 and its spread into the surrounding area. The reservoir 1 is filled with sanitary waste water by means of an external pump when it is re-showered or bathed, with excess water flowing into the sewer system via the open overflow 7 at the top of the inlet part 1 of the reservoir 1.
Če po ciklu obdelave vode in spiranja WC školjke v rezervoarju 1 ni na razpolago zadosten volumen odpadne sanitarne vode, se rezervoar 1 polni z vodovodno vodo do definiranega nivoja preko sistema nivojskega senzorja 3 in elektromagnetnega ventila za dotok vode iz vodovodnega omrežjaIf, after the cycle of water treatment and flushing of the toilet bowl, sufficient volume of waste water is not available in reservoir 1, the reservoir 1 is filled with tap water to the defined level via the level sensor system 3 and the solenoid valve for water supply from the water supply network
5. Količina te vode zadostuje za enkratno spiranje WC školjke z maksimalno definirano količino vode. Trdni delci, ki prihajajo v rezervoar 1 z odpadno sanitarno vodo in odmrli mikroorganizmi, se kopičijo v koničnem spodnjem delu rezervoarja 1. Preko elektromagnetnega ventila s časovnim regulatorjem5. The amount of this water is sufficient to flush the toilet once with a maximum amount of water. The solids entering the wastewater reservoir 1 and the dead microorganisms accumulate in the conical lower part of the reservoir 1. Through a solenoid valve with a time controller
6, ki je nameščen v koničnem delu na dnu vtočnega dela la rezervorja 1, se usedlina v določenih časovnih intervalih odplakuje v kanalizacijski sistem.6, which is located in the conical part at the bottom of the inlet part 1 of reservoir 1, the sediment flushes into the sewer system at certain intervals.
Sistem za obdelavo sanitarne odpadne vode in njeno ponovno uporabo, ki je predmet izuma, je zasnovan tako, da omogoča kompaktne tipske izvedbe v območju od 50 do 200 litrov, ki se lahko namestijo v sanitarne bloke posameznih stanovanjskih enot bodisi v nadometni bodisi podometni izpeljanki.The sanitary wastewater treatment and reuse system of the present invention is designed to allow compact type designs in the range of 50 to 200 liters, which can be installed in the sanitary blocks of individual housing units, either in the surface or subfloor version.

Izvedbeni primer temelji na rezultatih zaključenih preskusov biološkega odstranjevanja organskega onesnaženja in dezinfekcije odpadne sanitarne vode v pilotnem sistemu, ki je predmet izuma, kjer je bil s predhodnimi preskusi določen optimalni tip materiala za nosilec mikroorganizmov in razmerje med volumnom rezervoarja 1 in volumnom reaktorskega modula lc.The embodiment is based on the results of completed tests for biological removal of organic pollution and disinfection of sanitary wastewater in the pilot system of the invention, which, by preliminary tests, determined the optimal type of material for the micro-organism carrier and the ratio of volume of tank 1 to volume of reactor module lc.
Pilotni sistem je sestavljen iz rezervoarja 1 iz prozornega poliakrilata s poševnim dnom (15 cm x 60 cm x 67/55 cm) z volumnom 50 I s potopljenim reaktorskim modulom lc in modulom za dezinfekcijo 2, opremljenim z UV lučjo (nizkotlačna Hg žarnica, 254 nm, 17 W, Helios ltalquartz). Sistem je opremljen z dvema peristaltičnima črpalkama, elektromagnetnimi ventili 4,5,6 (Jakša) in ultrazvočnim nivojskim senzorjem 3 (Echosvvitch).The pilot system consists of a tank 1 of transparent polyacrylate with a sloping bottom (15 cm x 60 cm x 67/55 cm) with a volume of 50 I with a submerged reactor module lc and a disinfection module 2 equipped with a UV light (low pressure Hg lamp, 254 nm, 17 W, Helios ltalquartz). The system is equipped with two peristaltic pumps, solenoid valves 4,5,6 (Jakša) and ultrasonic level sensor 3 (Echosvvitch).
Reaktorski modul lc predstavlja košarica, obdana z vseh strani z mrežo iz nerjavnega materiala, ki je napolnjena z nosilcem mikroorganizmov (Mutag BioChip). Volumen reaktorskega modula lc znaša 'A volumna celotnega rezervoarja 1, volumen nosilca pa znaša 'A volumna reaktorskega modula lc. Lastnosti sanitarne odpadne vode se simulira z definiranim dodatkom preparatov za osebno higieno (tekočega mila, gela za tuširanje in šampona) v vodovodno vodo. Količina organskega onesnaženja v sanitarni odpadni vodi je določena-na osnovi podatkov iz literature (Eriksson et al., Characteristics of grey wastewater, Urban Water, 2002). Po teh podatkih znaša povprečna KPK (kemijska potreba po kisiku) vrednost sanitarne odpadne vode 150 mg/l, pri čemer se KPK vrednosti v izvedbenem primeru določa-s standardizirano analitsko metodo (SIST ISO 6060,1989). Koncentracijo mikroorganizmov v vodi se določa s standardizirano metodo (ISO EN ISO 6222,1999), ki podaja rezultate kot število kolonij (CFU)/ml.The reactor module lc is a basket surrounded on all sides by a mesh of stainless material filled with a micro-organism carrier (Mutag BioChip). The volume of the reactor module lc is 'A volume of the entire tank 1 and the volume of the carrier is' A is the volume of the reactor module lc. The properties of sanitary wastewater are simulated by the defined addition of personal hygiene products (liquid soap, shower gel and shampoo) to tap water. The amount of organic pollution in sanitary wastewater is determined-based on literature data (Eriksson et al., Characteristics of Gray Wastewater, Urban Water, 2002). According to these data, the average COD (chemical oxygen demand) value of sanitary wastewater is 150 mg / l, the COD values in the embodiment being determined by the standardized analytical method (SIST ISO 6060,1989). The concentration of microorganisms in water is determined by a standardized method (ISO EN ISO 6222,1999), which gives the results as colony counts (CFU) / ml.
Pri spremljanju delovanja pilotnega sistema za obdelavo sanitarne odpadne vode je bila simulirana dinamika nastanka sanitarne odpadne vode v štiričlanskem gospodinjstvu.The monitoring of the operation of the pilot sanitary wastewater treatment system simulated the dynamics of sanitary wastewater generation in a four-member household.
Ker sintetično pripravljena sanitarna odpadna voda ne vsebuje mikroorganizmov, ji je v začetni fazi preskusov dodana komunalna odpadna voda, da se na nosilnem materialu v reaktorskem modulu lc naselijo mikroorganizmi. Občutna razlika v izmerjenih KPK vrednostih v odpadni in obdelani vodi je znak, da je reaktorski modul lc postal biološko aktiven.Since the synthetically prepared sanitary wastewater does not contain micro-organisms, municipal wastewater was added to it in the initial phase of the tests to settle microorganisms on the carrier material in the reactor module lc. The significant difference in the measured COD values in the waste and treated water is an indication that the reactor module lc has become biologically active.
* ·* ·
Določena je bila KPK vrednost in število mikroorganizmov po dolgotrajnem (2 dni) zadrževanju odpadne vode v sistemu, ko je voda prisilno krožila med reaktorskim modulom lc in modulom za dezinfekcijo 2. KPK vrednost je znašala 62 mg/l; ta vrednost predstavlja preostalo količino organskega onesnaženja, ki pa biološko ni več razgradljivo in ga mikroorganizmi ne morejo uporabiti za prirast. Izmerjeno število mikroorganizmov v vodi, ki se je zadrževala v rezervoarju 1, je v povprečju znašalo 200 - 300 CFU/ml (mejna vrednost za pitno vodo znaša 100 CFU/ml). Meritve so pokazale, da je pilotni sistem odstranil organske snovi do KPK = 70 mg/l in vzdrževal koncentracijo mikroorganizmov pri 400 CFU/ml že po eni uri zadrževanja sanitarne odpadne vode v sistemu.The COD value and the number of microorganisms were determined after long (2 days) retention of waste water in the system when the water circulated between reactor module lc and disinfection module 2. The COD value was 62 mg / l; this value represents the residual amount of organic pollution, which is no longer biodegradable and cannot be used by microorganisms for growth. The measured number of microorganisms in the water retained in tank 1 averaged 200 - 300 CFU / ml (the drinking water limit was 100 CFU / ml). Measurements showed that the pilot system removed organic matter up to COD = 70 mg / l and maintained the microorganism concentration at 400 CFU / ml after one hour of retention of sanitary wastewater in the system.
Pilotni preskusi so tudi pokazali, da se lahko v kompaktnem sistemu za obdelavo sanitarne odpadne vode, ki je predmet tega izuma, pripravi vodo s takimi lastnostmi, da je ponovno uporabna za splakovanje WC školjke.Pilot tests have also shown that the compact sanitary wastewater treatment system of the present invention can produce water with such properties that it is reusable for flushing the toilet bowl.
Izvedbeni primer, naveden v opisu, služi obrazložitvi izuma in ne njegovemu omejevanju.The embodiment given in the description serves to explain the invention and not to limit it.
