Oxidation pond 6: the distributing artificial marsh sewage treatment system compiles through sewage and enters oxidation pond 6, and oxidation pond 6 is effectively further purified liquid waste through self-purification capacities.
Sewage Treatment in Process Design and principal pollutant:
Septic tank is that three compartment septic tanks 1 are by the A that links, B, three ponds of C form, middle by crossing excrement siphunculus 17 UNICOMs, establish sewage import 15 in the A pond, establish wastewater outlet 18 on the C pond, simultaneously at A, establish slag removing hole 16 on the B pond, it mainly is to utilize anaerobically fermenting, the principle that excrement and parasitic ovum proportion are easy to precipitate greater than general mixed solution proportion is crossed in the middle level, ight soil decomposes through the fermentation more than 30 days in the pond, the middle level liquid manure flow to B by the A pond successively, the C pond, to reach precipitation or to kill the purpose of parasitic ovum and pathogen enterobacteria in the ight soil, C pond liquid manure becomes the high-quality chemical fertilizer.
To enter the first pond be the A pond to fresh excreta by advancing excrement import 15, in the pond ight soil begin fermentation decompose, because the different liquid manures of proportion can be divided into three layers naturally, the upper strata is pasty state excrement skin, lower floor be block or a shape excrement slag, the middle level is the liquid manure of relatively clarifying.In upper strata excrement skin and lower floor's excrement slag, contain bacterium and parasitic ovum is maximum, it is minimum that the middle level contains worm's ovum, the middle level liquid manure of initial fermentation is the B pond through manure through pipe siphunculus 17 overflow to the second ponds, and excrement skin and the excrement slag detention of major part without fully fermentation continued to ferment in the first pond.The liquid manure that flows into the second ChiBChi decomposition of further fermenting, worm's ovum continues to sink, and pathogenic agent is dead gradually, and liquid manure obtains further innoxious, and the excrement skin of generation and excrement Thickness Ratio the first ChiAChi significantly reduce.The liquid manure that flows into the 3rd pond and be the C pond generally becomes thoroughly decomposed, and wherein germ and parasitic ovum are killed substantially.The 3rd pond function mainly plays the substantially innoxious liquid manure effect of storage.
The underground part structure in three-grid septic tank 1 lavatory by closet, advance soil pipe, manure through pipe, three-grid septic tank, cover plate five parts and form.Closet adopts through type, and advances soil pipe and connects.
Three-grid septic tank 1: cast-in-place with brick cement flour wall or cement, prefabricated all can, take " order " font as main Types, or " product " font, " fourth " font, volume reached manure storage 60 days.Three lattice pond significant depths should be no less than 1m, take water (flow) direction from A, B to C three lattice volume size by volume ratio be 2:1:3;
The type brick mix structure
(H) m of size L * B * H=(0.8+1.0+0.4) * 0.6 * 1.2.
Biological filter 4, biological filter 4 comprises two districts, being provided with bed of packings provides attached growth of microorganisms required surface.Two district's media are large and small pebbles 9,10 or the synthetic plastics filler of gravel, wood strip and all kinds and shape.
Pool wall is used for depositing filler, holding the waste water of batching, and pool wall can be Steel Concrete.
Water distribution system must guarantee water distribution uniformity, makes all fillers can both be wetted.It will affect the operating performance in filter tank.
Filler not only provides bond area for microorganism, and the stay mechanism of microorganism in the unit also is provided.Organic matter removal is identical with other aerobic treatment processes with the nitrated mechanism of nitrogen in the filter tank.Dissolved organic matter is utilized as carbon source and the energy of heterotrophic bacteria by diffusing into the microbial film that is positioned at filling surface.Ammonia nitrogen is by diffusing into microbial film, and part is synthesized microbial biomass by heterotrophic bacteria, and remaining is become nitrate nitrogen by oxidation by nitrobacteria.Organism and nitrogen is nitrated to cause the biomass of adding, and has increased the thickness of biomass.Come off when microbial film is blocked up, the microbial film after coming off enters in the processed water outlet and discharges.Metabolism plays control action kou to Medium Diffusion to microbial film.
Fluid flow pattern in the filter tank is generally considered to be the pulling flow type with dispersivity.Because the apposition growth of this liquid state and microorganism, different types of microorganism is surviving on the filter bed different depths.The common oxidation of coal in filter bed top and nitrogen are nitrated to be occured simultaneously, and heterotrophic bacteria is dominant bacteria, and most of carbonaceous organic material is removed on the top of filter bed.And current are when the filter bed bottom, and the carbonaceous organic material major part is removed, and COD drops to below the 20mg/L, limited the growth of heterotrophic bacteria, ammonia-nitrogen content is relatively high in the water at this moment, and nitrifier becomes dominant bacteria, and in microbial film stable growth, finish the oxidation to nitre nitrogen.
Compiled by artificial swamp 5 water outlets and to enter oxidation pond 6.Oxidation pond 6 is a kind of half artificial ecosystems, and the principle that it is purified liquid waste and the purification mechanism of natural water area are quite similar.Water weeds 12 is arranged such as Herba Eichhorniae, floating heart, barnyard grass, black algae in oxidation pond 6 water surface kinds, and cultivation there are aquatic bird, duck; Support in the water fishes and shrimps are arranged; In the wetland plant 7 of artificial swamp 5 plantation as Herba Eichhorniae, floating heart, barnyard grass, deceive algae, hybrid giant napier and at oxidation pond 6, the water weeds 12 of water surface planting can be the same or different; Waste water is in oxidation pond 6 interior stop processes, and pollutent is through dilution precipitation, the oxygenizement of aerobic microbiological, or the Decomposition of anaerobion and removing or stabilization; By the stereo biological chain that forms, thoroughly with few part nutritive substance in the middle water, nitrogen, phosphorus compound, organism purifies clean, makes at last water discharging up to standard.
The source of sewage: mainly be that domestic sewage in rural areas by using is bathing, kitchen water, the water of doing washing, the water etc. that goes to toilet, principal pollutant are pH, CODcr, BOD 5, ammonia nitrogen, total phosphorus, total nitrogen, suspended substance etc.
Sewage effluent water quality is carried out the one-level B standard of GB18918-2002 " urban wastewater treatment firm pollutant emission standard " after administering:
