Main processing working procedure systems explanation: like Fig. 1, shown in 2
Three-grid septic tank 1: septic tank adopts brick mix structure, and appearance is coated waterproof mortar, is mainly used in the pre-treatment of waste water, reduces pollution load;
Pipe network: pipe network sewage dedicated pipe.The pipe of the Zhi Guanyong φ 150mm that draws from each family, main pipe line φ 300mm;
Biological filter 4: adopt the concrete structure, appearance is coated waterproof mortar.Mainly be to utilize biologic packing material wherein to increase surface-area, increase adhering to of biological bacteria, through the metabolic characteristic decomposing organic matter of microorganism.Sewage stops certain hour at this, and the organism that is beneficial in the sewage is fully degraded;
Artificial swamp 5: adopt the concrete structure, appearance is coated waterproof mortar, and artificial swamp combines physics, chemistry and three kinds of biological effects to the processing of waste water.After the wet land system maturation, filling surface and root system of plant will form microbial film owing to a large amount of microbial growths.When waste water was flowed through microbial film, a large amount of SS was stopped by filler and root system of plant and holds back that organic pollutant then is removed through biomembranous absorption, assimilation and dissimilation.Because of root system of plant discharges the transmission of oxygen, make to occur aerobic, anoxic, anaerobic state in the environment around it successively in the wet land system, thus through nitrated, denitrification with contaminant removal, the realization qualified discharge;
Oxidation pond 6: the distributing artificial marsh sewage treatment system compiles entering oxidation pond 6 through sewage, 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 format manure pits 1 are by the A that links; B; C forms in three ponds; Middle by crossing excrement siphunculus 17 UNICOMs; On the A pond, establish sewage import 15; 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; Excrement is crossed in the middle level and parasitic ovum proportion is easy to sedimentary principle greater than general mixed solution proportion; 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 deposition 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 get into first pond be the A pond to fresh excreta by advancing excrement import 15, in the pond in ight soil begin fermentation decompose, because of the different liquid manures of proportion can be divided into three layers naturally, the upper strata is a pasty state excrement skin, lower floor is a bulk or a shape excrement slag, the middle level is more clarifying liquid manure.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 first pond.The liquid manure that flows into 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 and the excrement thickness of generation significantly reduce than first ChiAChi.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 basically.The 3rd pond function mainly plays the innoxious basically 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, be main type with " order " font, or " article " font, " fourth " font, volume reached manure storage 60 days.Three lattice pond significant depths should be no less than 1m, with water (flow) direction from A, B to C three lattice volume size by volume ratio be 2:1:3;
The type brick mix structure
Size L * B * H=(0.8+1.0+0.4) * 0.6 * 1.2 (H) m.
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 the large and small pebbles 9,10 or the synthetic plastics filler of gravel, wood strip and all kinds and shape.
Pool wall is used to deposit filler, holds the waste water of batching, and pool wall can be a Steel Concrete.
Water distribution system must guarantee water distribution uniformity, makes all fillers can both be wetted.It will influence 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 removal is identical with other aerobic treatment processes with the nitrated mechanism of nitrogen in the filter tank.Dissolved organic matter is utilized as the carbon source and the energy of heterotrophic bacteria through diffusing into the microbial film that is positioned at filling surface.Ammonia nitrogen is through 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 additional biomass, has increased the thickness of biomass.When microbial film is blocked up, come off, the microbial film after coming off gets in the water outlet that is processed 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 that has dispersivity.Because the apposition growth of this liquid state and microorganism, different types of microorganism is surviving on the filter bed different depths.Common oxidation of coal in filter bed top and nitrogen are nitrated to be taken place simultaneously, and heterotrophic bacteria is a 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 higher relatively in the water at this moment, and nitrifier becomes dominant bacteria; And in microbial film stable growth, accomplish oxidation to nitre nitrogen.
Compile entering oxidation pond 6 by artificial swamp 5 water outlets.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 like Herba Eichhorniae, floating heart, barnyard grass grass, black algae in oxidation pond 6 water surface kinds, and breed there are aquatic bird, duck; Support in the water fishes and shrimps are arranged; On artificial swamp 5 wetland plant 7 as the Herba Eichhorniae of plantation, floating heart, barnyard grass 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 in the stop process, and pollutent is through the dilution deposition, 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, processes water discharging up to standard at last.
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.
Administer back sewage effluent water quality and carry out the one-level B standard of GB18918-2002 " urban wastewater treatment firm pollutant emission standard ":
