Description
Technical field
This utility model relates to a kind of sewage disposal device, particularly one way of life biochemical wastewater treatment system.
Background technology
Existing lavatory waste water, usually through carrying out receiving pipe treatment technology after anaerobic tank process:
The principle of anaerobic tank handy organic sludge precipitation and anaerobic fermentation is come except the organic treatment facility of suspension in sanitary sewage, containing a large amount of feces, paper scrap, protozoon in sanitary sewage ... suspended solids concentration is 100 ~ 350mg/L, organic concentration CODCr is between 100 ~ 400mg/L, and wherein the organic concentration BOD5 of suspension is 50 ~ 200mg/L.Sewage enters the anaerobic tank precipitation through 12 ~ 24h, the float of removable 50% ~ 60%.The mud precipitated decomposes through the anaerobic fermentation of 2 to 3, makes the Organic substance in mud resolve into stable inorganic matter, and putrefactive primary sludge is converted into stable ripe sludge, changes the structure of mud, reduces the moisture content of mud.Periodically sludge clearing is transported outward, fill or be used as fertilizer.
Prior art there is problems in that
1, anaerobic tank only serves temporarily storage, buffering, solid retain and anaerobic digestion, and the COD of final outflow water does not reduce, it could even be possible to be raised, and COD:300 ~ 500mg/L;Water outlet major part blackout, ammonia nitrogen through anaerobic tank are the highest simultaneously, NH3-N;And the water blackout foul smelling taste after anaerobic tank, being not reaching to can be with emission request.
2, assembling in city or school that the anaerobic tank on ground is follow-up can reach country's emission request through receiving after pipe processes, but pipe cannot be received in some places, relative distribution edge in rural area, mountain area etc., ring mirror is caused and has a strong impact on by institute's effluent sewerage.
3, anaerobic tank is relatively big through the sludgd deposition amount of ripening, within general 3 to 5 months, needs scarfing cinder, and foul smelling is relatively big on the impact of ring mirror, the Treatment of Sludge difficulty of particularly ripening.
4, major part anaerobic tank be embedded in underground, be easy to every rainy season occur overflow, then anaerobic tank do not play the effect because of having instead may one-tenth come polluter.
5, keeping because of unmanned duty, anaerobic tank is splashed the reason such as swollen because of float, anaerobic fermentation mud, easily causes anaerobic tank blocking, has a strong impact on properly functioning.
6, major part public lavatory institute, because user is unpredictable, has many non-degradable things to enter system, also can affect the properly functioning of anaerobic tank.
7, anaerobic tank is to utilize organic sludge to pass through anaerobic fermentation, and in high-density region, biogas spill-over, particularly summer, biogas is inflammable, has potential safety hazard, environment is also resulted in pollution simultaneously.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the utility model discloses one and directly processes sanitary sewage, prevents the sanitary sewage biochemical treatment system of secondary pollution.
Technical scheme: the utility model discloses one way of life biochemical wastewater treatment system, including cesspool, is provided with micro power grid, it is characterized in that, also include biochemical treatment system in described cesspool；Described biochemical treatment system includes anaerobic pond, Aerobic Pond, sedimentation tank and the sterilization pool being sequentially connected；Described anaerobic pond is provided with the biologic packing material of suspension；Described Aerobic Pond is provided with the biologic packing material of suspension, at the bottom of pond, is provided with aeration plate；Described sedimentation tank top is provided with filtering baffle.
Wherein, described anaerobic pond, Aerobic Pond, sedimentation tank connect with sterilization pool top.
When this utility model uses, sanitary sewage being entered cesspool, after the preliminary solid-liquid separation of micro power grid, solid life refuse separates discharges, and carries out and carries out recycling compost treatment；Filtrate enters biochemistry pool；
When filtrate enters anaerobic pond, sanitary sewage filtrate has containing ammonia, nitrogenous, the phosphorous and organic characteristic of height, biologic packing material in anaerobic pond has efficient hydrophilic and parent's microbes, during catalytic oxidation, microorganism in filtrate is attached on biologic packing material, forming biological filtering membrane, filtrate enters Aerobic Pond after filtering；
While aeration plate aeration, the filtration through biologic packing material completes nitrification and denitrification reaction, and after entering sedimentation tank precipitation, clear water is separated out by filtering baffle, enters after sterilization pool filters and is expelled directly out.
Beneficial effect: sanitary sewage biochemical treatment system disclosed in this utility model, small, structural integrity good, corrosion-resistant, equipment is succinct, easy for installation, simple to operate, continuously-running, it is not necessary to special messenger's duty is kept；Noiselessness, free from extraneous odour, sludge quantity reduce, low erosion degree (water outlet SS be less than 30mg/L) environmental friendliness, high treating effect, sanitary sewage after integration biochemical treatment up to direct emission request.
