Description

A kind of anaerobism, aerobic multistage wet field facilities for treating sewage
Technical field
The invention belongs to water purification technology field, it is related to sewage-treatment plant, especially a kind of anaerobism, aerobic multistage wet field facilities for treating sewage.
Background technology
With the development of rural economy, rural area living standard is improved constantly, and Development of China's Urbanization is also constantly promoted, therefore the also more and more higher of the requirement to living environment, meanwhile, the discharge capacity of domestic sewage in rural areas is also continuously increased.At present, the wastewater treatment rate in China city has reached certain level, but the sanitary sewage disposal of rural area is also almost blank.For a long time, lacked of capital and to the thin of Rural Water Environment protective awareness due to administering, the sanitary sewage of rural area is unprocessed just directly to be discharged, sanitary sewage that is unprocessed or dealing with improperly turns into the one of the main reasons of rivers and lakes water quality deterioration.Therefore, it is necessary to implement the design and construction waste water treatment project for production actual in village dirty angle in vast rural area.
The patent of invention of application number 201410187150.8, a kind of multi-stage sewage processing system is disclosed, including the sand-catching apparatus for being used to remove sewage sand grains set gradually, the odor removal that catchments eliminated for dispatch sewage and by sewage smells, sewage decomposition apparatus for degrading and stablizing the organic matter in sewage, for by nitrogen compound in water, phosphorus compound, the wetland filter that hardly degraded organic substance is removed, for the quartz sand filter for stopping suspension in water, absorb peculiar smell and adsorb the active carbon filtering device of harmful substance and the ecological recycling equipment for increasing water quality.Multi-stage sewage processing system, it can remove the solid impurity in sewage, colloidal substance, nitrogen compound, phosphorus compound, heavy metal, hardly degraded organic substance, bacterium and virus etc., obtain ideal water quality.The dependence chemical method processing excessive in sewage disposal process of above-mentioned patented product carries out sewage disposal, and this sewage water treatment method cost is higher, and easily causes other to endanger environment during chemical reagent use.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of anaerobism, aerobic multistage wet field facilities for treating sewage, by way of physical filtering and biodegradation are combined, country sewage qualified discharge is realized, and sewage-treatment plant is economic and practical, operating cost is low.
Technical scheme is as follows:
A kind of anaerobism, aerobic multistage wet field facilities for treating sewage, by grille well, Anaerobic Contact pond, aerobic wetland pond, anaerobism wetland pond and water outlet well construction.It is serial connection that sewage-treatment plant, which respectively constitutes product, is grille well, Anaerobic Contact pond, aerobic wetland pond, anaerobism wetland pond and wet well successively from front to back.
Each blowdown point initially enters the grille well in wet field facilities for treating sewage by independent pipeline sewage effluent after centralized collection.A set of filtering grid is set in grille well, processing removal is carried out to suspension in sewage.SS, floating type COD etc. are substantially reduced in water after grid is handled, and filter grid slag is by transporting outward landfill disposal.Grille well, which can be amputated in sewage, carries thick debris secretly, it is ensured that the normal operation of subsequent processing units, while observing into aqueous condition.
Removed by the suspension of filtering grid, now the organic and inorganic of the bulky grain suspension in water waits material to remove totally substantially, and now into Anaerobic Contact pond, its anaerobism function is played while this regulating water quality, water, organic matter in degraded sanitary sewage, improves the absorptivity of its vegetation.Partial organic substances are removed by anaerobic processes, organic matter of sewage concentration is reduced and larger molecular organicses in sewage is decomposed into small organic molecule, by carrying out depth pretreatment behind Anaerobic Contact pond.
Aerobic wetland pond is formed using the filled stones such as cobblestone, rubble and filter sand landfill, plant a variety of water plants in top layer, natural wind energy aeration increase microbial activity is utilized by vent riser and tunnel ventilation pipe in aerobic wetland pond, add the preferable filler of permeability and select suitable vegetation Implantation Rate to increase oxygen content, while organic pollution is handled, Nitrogen/Phosphorus Removal is further lifted.The sewage stream flowed out from Anaerobic Contact pond passes through aerobic wetland pond, and the biological degradation function through the plant in wetland, partial contamination thing is digested, decomposed and absorbed.The water quality for flowing through aerobic wetland is got a promotion, and the sewage after Partial digestion is concentrated in the antipriming pipe in aerobic wetland pond, and anaerobism wetland pond is then flowed into by the road.
Filler is identical with aerobic wetland pond in anaerobism wetland pond, and surface grafting aquatic plant species are also identical, but without air pipeline in anaerobism wetland pond.Part microorganism in sewage carries out anaerobic respiration in anaerobism wetland pond, carries out biodegradable and is absorbed by water plant.For the organic matter bed mud produced by anaerobic fixed film reactor, after periodic cleaning, place into dung yard and carry out compost, being re-used as organic fertilizer after curing of compost is utilized.
The vegetation in aerobic wetland pond and anaerobism wetland pond absorbs water quality nutrition, and the dirty Organic substance in water of degraded, most organic pollution is handled by vegetation absorption, and N, P nutrients of part are directly absorbed by wetland plant.Whole wet land system is in a series of anaerobism, aerobic state, to N element formation nitrification, denitrification environment, can substantially reduce ammonia nitrogen concentration.
Sewage flows through grille well, Anaerobic Contact pond, aerobic wetland pond, anaerobism wetland pond, and carries out physical filtering, precipitation and biodegradation wherein, finally reaches water quality discharge standard, is discharged through wet well.
The invention has the advantages that the anaerobism, aerobic multistage wet field facilities for treating sewage:
(1) introduce natural air and carry out aerobic wetland variation, nitrification and denitrification can be strengthened, increase COD clearance and de- N rates;
(2) organic matter for being decomposed, being absorbed in sewage using water plant, while vegetation is abundant, builds good ecological environment;
(3) once input is used for a long time, it is easy to safeguard, and wastewater treatment efficiency is good, applied widely.
