Description

A kind of anaerobism, aerobic multistage wet field facilities for treating sewage

Technical field

This utility model belongs to water purification technology field, relates to sewage-treatment plant, especially a kind of anaerobism, Aerobic multistage wet field facilities for treating sewage.

Background technology

Along with the development of rural economy, rural area living standard improves constantly, and Development of China's Urbanization the most constantly pushes away Entering, therefore the requirement to living environment is more and more higher, and meanwhile, the discharge capacity of domestic sewage in rural areas is the most continuous Increase.At present, the wastewater treatment rate in China city has reached certain level, but the life of rural area Sewage disposal of living is also almost blank.For a long time, lack of capital due to improvement and Rural Water Environment is protected Consciousness thin, the sanitary sewage of rural area is unprocessed the most directly to be discharged, unprocessed or deal with improperly Sanitary sewage become the one of the main reasons of rivers and lakes water quality deterioration.Therefore, it is necessary in vast agriculture Village implements the design and construction waste water treatment project for product dirt angle actual in village.

The patent of invention of application number 201410187150.8, open a kind of multi-stage sewage processing system, including depending on Secondary setting for remove the sand-catching apparatus of sand grains in sewage, for dispatch sewage and by sewage smells eliminate Catchment odor removal, for the organic sewage decomposition apparatus degraded and stablize in sewage, for by water Wetland defecator that nitrogen compound, phosphorus compound, hardly degraded organic substance are removed, for by float in water The quartz sand filter that stops, absorb abnormal flavour and the absorption active carbon filtering device of harmful substance and be used for carrying The ecological recycling equipment of high water quality.Multi-stage sewage processing system, it can be by the solid impurity in sewage, colloid Material, nitrogen compound, phosphorus compound, heavy metal, hardly degraded organic substance, antibacterial and virus etc. are removed, To ideal water quality.The dependence chemical method process that above-mentioned patented product is too much in sewage disposal process Carrying out sewage disposal, this sewage water treatment method is relatively costly, and the most right during chemical reagent use Environment causes other to endanger.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of anaerobism, aerobic multistage wetland sewage disposal dress Put, by the way of physical filtering and biodegradation combine, it is achieved country sewage qualified discharge, and dirty Water treatment facilities is economic and practical, and operating cost is low.

The technical solution of the utility model is as follows:

A kind of anaerobism, aerobic multistage wet field facilities for treating sewage, by grille well, Anaerobic Contact pond, aerobic wet Pond, ground, anaerobism wetland pond and wet well composition.It is connected in series, in the past that sewage-treatment plant respectively forms product It is grille well, Anaerobic Contact pond, aerobic wetland pond, anaerobism wetland pond and wet well the most successively.

Each blowdown point passes through independent pipeline sewage effluent, initially enters wetland sewage disposal after centralized collection Grille well in device.Grille well sets a set of filtering grid, carries out float in sewage processing and remove. After grid processes, in water, SS, floating type COD etc. are substantially reduced, and filter grid slag is by transporting outward at landfill Reason.Grille well can amputate in sewage carries thick foreign material secretly, it is ensured that subsequent processing units properly functioning, with Time observe water inlet situation.

Through the suspended substance removal of filtering grid, the organic and inorganic of the now suspension of the bulky grain in water waits material Substantially, remove clean, now enter Anaerobic Contact pond, while this regulating water quality, the water yield, play it detest Oxygen function, the Organic substance in degraded sanitary sewage, improves the absorbance of its vegetation.Removed by anaerobic processes Partial organic substances, reduces organic matter of sewage concentration and that larger molecular organics in sewage is decomposed into little molecule is organic Thing, by carrying out degree of depth pretreatment behind Anaerobic Contact pond.

Aerobic wetland pond uses the filled stone landfills such as cobblestone, rubble and mistake filter sand to form, and top layer plantation is many Plant water plant, aerobic wetland pond utilizes natural wind energy aeration to increase by vent riser and tunnel ventilation pipe Add microbial activity, add the preferable filler of permeability and select suitable vegetation Implantation Rate to increase Oxygen content, while processing organic pollution, promotes Nitrogen/Phosphorus Removal further.From Anaerobic Contact pond The sewage stream flowed out is through aerobic wetland pond, the biological degradation function of the plant in wetland, partial contamination thing Digested, decomposed and absorbed.The water quality flowing through aerobic wetland gets a promotion, the sewage collection after Partial digestion In in antipriming pipe in aerobic wetland pond, flow into anaerobism wetland pond the most by the road.

In anaerobism wetland pond, implant is identical with aerobic wetland pond, and surface grafting aquatic plant species is the most identical, But without air pipeline in anaerobism wetland pond.Part microorganism in sewage carries out anaerobic in anaerobism wetland pond and exhales Inhale, carry out biodegradation and absorbed by water plant.For bed mud organic produced by anaerobic fixed film reactor, After periodic cleaning, place into dung yard and carry out compost, be re-used as fertilizer after curing of compost and utilize.

Aerobic wetland pond absorbs water quality nutrition with the vegetation in anaerobism wetland pond, the dirty Organic substance in water of degraded, big portion The organic pollution divided is processed by vegetation absorption, and N, P nutrient of part is directly absorbed by wetland plant.Whole Individual wet land system is in a series of anaerobism, good oxygen condition, and N element is formed nitrification, denitrification environment, Ammonia nitrogen concentration can be substantially reduced.

Sewage flows through grille well, Anaerobic Contact pond, aerobic wetland pond, anaerobism wetland pond, and carries out wherein Physical filtering, precipitation and biodegradation, finally reach water quality discharge standard, discharges through wet well.

The invention have the advantages that this 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 lead；

(2) utilizing the Organic substance that water plant is decomposed, absorbs in sewage, vegetation is enriched simultaneously, builds good Ecological environment；

(3) once put into life-time service, it is easy to safeguard, and wastewater treatment efficiency is good, applied widely.
