Description
Technical field
The invention belongs to technical field of buildings, particularly relate to a kind of green ecological four grid septic tank and sewage water treatment method.
Background technology
Septic tank is process ight soil and the equipment of in addition filtering-depositing; Its principle is that cured article decomposes at the bottom of pond, and the aquation object on upper strata, enters pipeline and flow away, prevent line clogging, has sufficient time hydrolysis to solidification object rubbish such as () ight soil; Septic tank refers to and is precipitated by sanitary sewage lattice, and mud is carried out to the small-sized process structures of anaerobic digestion.
Septic tank the earliest originated from the Europe in 19th century, apart from the history of modern existing more than 100 year; The initial object arranging septic tank in urban life district gets fertilizer in order to long-pending. along with the progress of urbanization and the aggravation of environmental pollution, septic tank serves active effect to protection water body; Now, in the many big cities of China, septic tank provides the effect of fertilizer substantially to disappear for agriculture production, and septic tank is one of basic measures becoming environment protection.
Septic tank is basic sludge treatment facilities, and be also simultaneously the pre-treatment facility of sanitary sewage, its effect shows: the environmental health 1, ensureing living community, avoids sanitary sewage and pollutent in the diffusion of living environment.2, in the Working environment of septic tank anaerobism corruption, mosquitos and flies worm's ovum is killed.3, provisional storage mud, organic sludge carries out anaerobism corruption, and the organic sludge of slaking can be used as agricultural fertilizer.4, the pre-treatment (coagulation) of sanitary sewage, precipitated impurities, and larger molecular organics is hydrolyzed, become the small organic molecules such as acid, alcohol, improve follow-up sewage disposal.
Septic tank is a kind of principle utilizing precipitation and anaerobically fermenting, removes the organic treatment facility of suspension in sanitary sewage, belongs to elementary transitionality life process structures; Containing a large amount of ight soil, paper scrap, protozoon in sanitary sewage ... suspended solids concentration is 100 ~ 350mg/L, and organic concentration CODCr is between 100 ~ 400mg/L, and wherein the organic concentration BOD5 of suspension is 50 ~ 200mg/L; Sewage enters the precipitation of septic tank through 12 ~ 24h, can remove the suspended substance of 50% ~ 60%; The mud precipitated decomposes through the anaerobically fermenting of more than 3 months, and make the inorganics that the organic substance decomposing in mud becomes stable, putrefactive raw sludge is converted into stable ripe sludge, changes the structure of mud, reduces the water ratio of mud.Regularly sludge clearing is transported outward, landfill or be used as fertilizer.Require: the sediment fraction of septic tank and the calculating volume of corruption part, should determine by " Code for design of building water supply and sewerage " (GB50015-2003) 4.8.4 ~ 4.8.7 article; Sewage residence time in septic tank should adopt 12h ~ 24h.For the Sewage treatment systems without sludge disposal, septic tank volume also should comprise the volume of storage mud.
The application of traditional manure pit has had more than 100 year history, technological line is the pattern that sewage contacts with mud, the sludge digestion degraded of deposition produces the digestion gas such as biogas, carbonic acid gas, hydrogen sulfide, the Float upward function of digestion gas produces disturbance to mud, digestion gas can allow mud more abundant with mixing of biological flora to the perturbation action of mud, contributes to digestion degraded.But base sludge rises with digestion gas, after bubble effusion, mud precipitates downwards again, and these rise and the mud of precipitation pollutes sewage again.
Under contacting at cesspool sewage the technology mode mixed with mud, affect precipitation and the effluent quality of septic tank, need to extend dwell time of sewage to improve sedimentation effect and effluent quality, dwell time of sewage is generally 12 ~ 24 hours.
Three phase separation septic tank technology is on the basis of traditional manure pit, remain the advantage of muddy water mixing in septic tank, add the technology of " sewage, mud, digestion gas " three phase separation, in the water side of septic tank, three-phase separating device is set, make the mud of water side, digestion gas is separated with sewage treatment process, avoid air supporting phenomenon to the interference of sewage disposal.The settling bath reference horizontal sedimentation tank technological standard of water side, within settlement of sewage time 2 h.
The volume of septic tank is made up of sewage volume and mud volume, dwell time of sewage 4-6 hour in three phase separation septic tank, relative to dwell time of sewage in muddy water hybridization manure pit 12 ~ 24 hours, by shortening dwell time of sewage and save useful volume, save useful volume and can store more mud.
The ultimate principle of septic tank utilizes the proportion of parasitic ovum to be greater than fecaluria mixed solution and the principle such as the precipitating action that produces and the fermentation of ight soil closing anaerobic, liquefaction, ammonification, biological antagonist removing and kill parasitic ovum and germ, control mosquitos and flies to multiply, thus reach the object of decontamination of human excreta.Three-grid septic tank is made up of three ponds be connected, middle by manure through pipe UNICOM, mainly utilize anaerobically fermenting, excrement is crossed in middle level and parasitic ovum proportion is greater than general mixed solution proportion and be easy to precipitate principle, ight soil decomposes through the fermentation of more than 30 days in pond, middle level liquid manure flow to 3 ponds by 1 pond successively, to reach the object precipitating or kill parasitic ovum and pathogen enterobacteria in ight soil, the 3rd pond liquid manure becomes high-quality chemical fertilizer.
The requirement of the time that three-grid septic tank volume should become thoroughly decomposed according to number of users, amount of flush water, manure fermentation and heavy ovum sterilizing decides.Become thoroughly decomposed time and pathogenic agent death time of manure fermentation calculated by 30 days, and wherein need stop 20 days in the first pond, the second pond stops 10 days, and the 3rd pool volume is at least two pond sums.
