Description
Technical field
The utility model is related to water process more particularly to a kind of static bed biomembrane containment type light electrolysis advanced nitrogen dephosphorization
Cabin.
Background technology
Sanitary sewage often contains a large amount of phosphorus, and algae excessive propagation can be caused by being discharged into water body, led to body eutrophication, made
Water quality deterioration.In sanitary sewage, 80% phosphorus comes from body discharges, remaining comes from washes and exemplary food waste.Wherein
Powdered Detergent Containing Phosphate is the main source of life phosphorus-containing wastewater.Phosphorus is the critical nutrients for causing body eutrophication.Water body is rich
Nutrient laden not only results in algae in water and overgrows, and oxygen content of water can be made drastically to decline, and influences the aquatiles such as fish
Existence.Body eutrophication shows as wawter bloom in lake, reservoir.In order to administer above-mentioned harm, must just reduce at sanitary sewage
The content of phosphorus is discharged in reason.
Promotion with people to environmental quality requirement, sewage discharge require also gradually stringent the removal of nitrogen, phosphorus etc.
Get up.In comparison, phosphorus can utilize chemical precipitation method to remove, and the degradation of nitrogen then relies primarily on biological treatment, this is just
It is required that sewage treatment process unit need to be reinforced considering Denitrogenation.
China's town sewage plant Effluent criteria is secondary discharge standard before 2002, wherein only ammonia nitrogen (NH3-N) refers to
Mark requires, and does not have total nitrogen index request, and in this case, NH3-N can be oxidized to nitrate nitrogen by aeration and biological processing procedure, realizes
Qualified discharge.Currently, being typically employed at conventional two level for the domestic and international decentralized type sewage treatment facility of the removal of nitrogen in sewage
Depth denitrification is carried out after reason and proposes mark transformation, and this technology is intended to the depths of the regional decentralized type sewage processing equipment such as key breakthrough rural area
Degree denitrification puies forward mark technology, and implementation focus engineering proposes mark transformation, completes utilization of wastewater resource degree.

It can not estimate, generally need to additionally increase medicine storing pot and metering pump, and a worker need to be increased and carry out plant maintenance and medicine daily
Prepared by agent, wide, the remote feature of distance is distributed for rural area, so safeguards and brings additional equipment cost and manpower maintenance cost；
On the other hand,, can not be lasting although reaction is rapid in conventionally employed dosing technique, it needs persistently to add using artificial or equipment
Medicine can not be suitable for the distributed small-sized sewage treating system in rural area, and the indexs such as suspended matter, total phosphorus, floating oil, coloration can not
National water process standard is stably reached, can not accomplish water quality advanced processing；According to the sewage disposal system of reverse osmosis membrane structure
Although treatment effect is pretty good, construction cost is high, and for rural area distribution small-sized sewage treating system, treating capacity is little, adopts
It is domestic at present mainly to have precast concrete pond body, glass fiber reinforced plastic tank, carbon steel tank for buried structure with buried structure；Wherein, in advance
For concrete basin processed because of long construction period, Corrosion Protection is poor, forms the shortcomings that leakage easily pollutes water body and is not suitable for
Rural sewage treatment；Glass fiber reinforced plastic tank is because of its poor rigidity, and mutability, long-term temperature tolerance is poor, while anti-aging property is low, manufacture craft
Not environmentally lead to secondary environmental pollution dangerous health simultaneously；For carbon steel tank because intensity is low, poor corrosion resistance is unable to reach rural area
The topology requirement of the buried equipment of sanitary sewage；It is badly in need of a kind of novel suitable for the distributed deep phosphorous removal in rural area and denitrification equipment
Or technology.

In, as shown in fig. 6, the width in sustained release channel is the caliber of double joint static bed biomembrane pipe 6；Wherein, dash area is to be placed with
The static bed biomembrane pipe 6 of micro-electrolysis stuffing, blank parts are not to be placed with the static bed biomembrane pipe 6 of micro-electrolysis stuffing.It answers
Work as understanding, the quantity in the sustained release channel in cabin ontology 1 can be unique passage or a plurality of channel in the same direction, it is common complete from
Water inlet 3 is directed toward the process of water outlet 4.Specifically, it is raising water treatment efficiency, the axis of the axis and water outlet 4 of water inlet 3
It is not conllinear, direct convection current can not be formed after making wastewater influent, treatment sewage is avoided just to be flowed directly to water outlet without sustained release channel
Mouth 4 to improve reaction efficiency, ensures that reaction is abundant, as shown in figure 3, agitating device 7 is installed on cabin ontology 1 in one embodiment
The plane that the central axis of center, the axis of water inlet line 5 and cabin ontology 1 is formed is vertical with 7 rotary shaft of agitating device
Plane included angle is 25 ° -35 °, and 4 position of water outlet is with 3 position of water inlet about 1 central axis central symmetry of cabin ontology.
Particularly, the caliber of static bed biomembrane pipe 6 determines that pipe porosity, pipe porosity determine mixing effect, stirring effect
It is decisive and resolute to determine removal rate and ability；On the one hand, caliber determines that the quantity for the micro-electrolysis material stacked in same volume finally influences
Phosphor-removing effect is handled, caliber is bigger, and accumulation micro-electrolysis stuffing quantity is more, and treatment effect is better；On the other hand, caliber determines solid
The specific surface area of fixed bed biology membrane tube 6 finally influences the quantity of the microorganism of carry, influences denitrification effect, and caliber is bigger, compares table
Area is smaller, and microbial biomass is fewer, and denitrification effect is poorer, but simultaneously, and caliber is smaller, is more likely formed in pipe and blocks, same to influence
Biofilm effect.Wherein, the caliber (diameter value) of static bed biomembrane pipe 6 is [2.5,8] cm, as shown in the table, it is preferable that fixed
When bed 6 caliber of biological membrane tube is 5.5cm, denitrogenation and dephosphorization resultant effect are best, meet rural area distributing water process requirement.
Behind the sustained release channel formed through static bed biomembrane pipe 6, the phosphorus concentration in sewage reaches country-level A standards, takes off
Nitrogen effect is preferable, and in such a way that light electrolysis is combined with biofilm, and difference and traditional dosing aeration mode, acid-base property is without adjusting
It is whole, while non-aeration structure is used, medicament slow release, medicament bulk life time is long, fully meets the distributed water process in rural area
Processing requirement.
The lattice of micropore is in netted diamond hole, and accounting is larger, and flow passability is good；When micro-electrolysis stuffing consumes, it is only necessary to
Static bed biomembrane pipe nozzle supplements micro-electrolysis material；And tube wall surface passes through specially treated, is conducive to microorganism carry, needs
Bright is that water body oxygen is consumed in micro-electrolysis material reaction process, and dissolved oxygen is less than 0.5mg/L in entire nacelle, is conducive to denitrification
The anoxic denitrification of bacterium, denitrification effect are preferable.
