Abstract
The utility model discloses a novel domestic sewage treatment device which consists of three parts namely a prepositioned denitrification tank, a micro-sludge biodegradation tank and an auxiliary wetland plant absorption system, wherein the front section of the prepositioned denitrification tank is a reaction zone in which a sewage inlet, a nitration liquid backflow water inlet and a contacting and mixing agitation pump of sewage and a nitration liquid are arranged; the back section of the prepositioned denitrification tank is a solid-liquid separation zone which is provided with a filter filling material; the micro-sludge biodegradation tank is formed by successively arranging porous water distribution walls and separated biological carrier filling materials at intervals and arranging a perforation aeration pipe at the bottom of the tank; the micro-sludge biodegradation tank is provided with a reflux pump for refluxing nitration liquid backflow water; and the auxiliary wetland plant absorption system consists of auxiliary constructed wetland grading medium packing filter layer of above level two and a balancing plant absorption layer. By using the novel domestic sewage treatment device, the technical problems that in the traditional municipal sewage treatment process, occupied area is large, investment is large, sludge treatment needs to be carried out and the like are solved.
Description
Technical field
The utility model belongs to field of environment engineering technology, relates to a kind of sewage treatment unit, relates in particular to the sewage treatment unit of a kind of employing Prepositive denitrification pond-little sludge biodegrading pond-auxiliary wetland plant absorption system (being called for short AOF technology).
Background technology
China's urban wastewater treatment firm dominance technology generally adopts activated sludge process at present, for example oxidation ditch, A
2Technologies such as/O, SBR, CAST, MSBR, ICEAS, technical process is long, and the pond body structure is complicated, and excess sludge is many.Because the productivity ratio of activated sludge process own is higher, because mud has produced a series of problem, such as problem among the process of follow-up disposal and secondary pollution problem.Simultaneously, WWT in factory also exists the problem of high energy consumption.The special 11th Five-Year that gets into, since 12, country call energy-conservationly subtract, target such as blowdown mud decrement, therefore from technological development and treatment process, reducing the mud output is more satisfactory technological line.Have in the research at present: the first, reactor drum mud when disposing of sewage is wanted decrement, mainly is to be trapped in the reactor drum according to environment and microbial diversity, second, high concentration microorganism system, the 3rd, the outflow mud of purifying waste water.
Summary of the invention
The purpose of the utility model is to provide a kind of novel sewage treatment unit, and big to solve the floor space that traditional town sewage treatment process exists, investment is many, needs technical problems such as sludge treatment.
The utility model realizes that the technical scheme of foregoing invention purpose is following:
A kind of novel sewage treatment unit is made up of Prepositive denitrification pond, little sludge biodegrading pond and three parts of auxiliary wetland plant absorption system; Prepositive denitrification pond leading portion is a reaction zone, has sewage water inlet, nitrification liquid recirculation water inlet, and be provided with sewage and nitrification liquid contact, mix the stirring pump, back segment is a solid-liquid displacement zone, is provided with filter packing; Little sludge biodegrading pond is provided with by the porous water distribution wall and the bio-carrier of wandering about as a refugee successively at interval, and is provided with the boring aeration pipe composition in the bottom, pond, on little sludge biodegrading pond, is provided with the reflux pump that supplies the nitrification liquid recirculation water to reflux; Auxiliary wetland plant absorption system joins the media filtration packing layer by the indirect labor's wetland more than the two-stage and balance plant absorbing layer is formed.
The beneficial effect of the utility model is: need not increase new structures owing to transform, newly-built sewage work can use simple pond shape structure or the good area of soil condition to adopt the anti seepage membrane mode, can save construction investment and occupation of land in a large number.Because the bio-carrier distribution of material that bio-carrier adopts is extensive, the project construction locality can provide, and can save construction investment greatly in addition.Because this technology hydraulic detention time is short, can save construction investment greatly.
Description of drawings
Fig. 1 is the structure principle chart of the utility model.
Number among the figure: 1 Prepositive denitrification pond, 2 little sludge biodegrading ponds, 3 auxiliary wetland plant absorption systems, 4 stir pump; 5 filter packings, 6 porous water distribution walls, 7 bio-carriers of wandering about as a refugee, 8 boring aeration pipes; 9 reflux pumps, 10 grating media filtration packing layers, 11 balance plant absorbing layers.
Embodiment
Can see that from Fig. 1 the utility model implements to adopt AOF technology sewage treatment unit, supply three parts to form by Prepositive denitrification pond 1, little sludge biodegrading pond 2 and auxiliary wetland plant absorption system 3.Prepositive denitrification pond 1 is contacted, mixes through stirring pump 4 by sewage water inlet, nitrification liquid recirculation water, carries out solid-liquid separation through filter packing 5 then.
Water after little sludge biodegrading is handled by Prepositive denitrification gets into the bio-carrier 7 of wandering about as a refugee through porous water distribution wall 6 and contacts with air through bottom perforated aeration tube 8 aerations; Can in same reactor drum, form multi-form fluidised form on the different levels through porous microbial carrier and interval aeration; Form numerous anaerobism, anoxic, aerobic zone, thereby realize the removal and the sludge reduction of hardly degraded organic substance.In the microbe carrier sewage disposal technology, there are anaerobism, anoxic, aerobic zone,, discharge CO2 at the aerobic zone organism synthetic aerobic sludge that is decomposed; Aerobic sludge is broken down into lipid acid, polysaccharide, extracellular enzyme and protein etc. at anaerobic zone, and the extracellular enzyme that discharges also helps the degraded of mud; The degraded product of anaerobic zone gets into next aerobic zone and is decomposed again.Organism in the water is fully degraded, and produces a large amount of microbial films simultaneously, is trapped within the bio-carrier surface for a long time, and is endogenous nitrated through the final realization of anaerobism anoxybiotic alternating action; Nitrification liquid refluxes like Prepositive denitrification pond 2. through reflux pump 9
The water outlet that after handle in little sludge biodegrading pond, has a small amount of suspended substance gets into auxiliary wetland plant absorption system 3; Through the multistage absorption of joining the filtration of media filtration packing layer 10 and passing through balance plant absorbing layer 11 of indirect labor's wetland, guarantee that organism, ammonia nitrogen, phosphorus, SS reach emission standard.
The utility model is directly transformed in the biochemical section of the sewage work that has built up and is added, and newly-built sewage work can use simple pond shape structure or the good area of soil condition to adopt the anti seepage membrane mode.Wetland plant can suit measures to local conditions to adopt local natural phant and natural carrier material.
The utility model and common process leading indicator contrast like following table:
