Description
Affiliated technical field
The present invention relates to a kind of ecological blowdown ditch building technology, belong to sewage treatment area, especially for the ecological purification technique building technology of Rural Waste Water.
Background technology
Wash away the rainwash of generation, high density percolate that dumping produces, peasant household's cultivation (chicken and duck and pig ox) livestock and poultry uncontrollable discharge behind the sanitary wastewater that Rural Waste Water mainly produces from every family (kitchen washing draining, the daily laundrywastes of washing one's face and rinsing one's mouth, garden wash-down water), colony house cultivation and lavatory draining, garden and the road rain and wash away the sewage, farmland production (growing vegetables of high rich water etc.) efflux wastewater etc. of generation through water.Contain the organism such as Mierocrystalline cellulose, starch, carbohydrate, fat, protein in the Rural Waste Water, also be rich in the inorganic nutrients salts such as nitrogen, phosphorus, microbe species is abundant, and contains multiple pathogenic bacteria.Rural Waste Water has a large capacity and a wide range, discharges dispersion, organic concentration is low, and it is a difficult problem that faces in the new countryside construction that Rural Waste Water is administered.For Rural areas sparsely populated, that economy falls behind relatively, particularly remote border area, mountain area and karst region, because special economic condition, being uneven of geology and geomorphology and physical features, can't lay on a large scale pipe network or lay the pipe network cost high, and because relief is larger, lives and relatively disperse, Rural Waste Water is difficult to effectively collect and the more pumping equipment of needs and energy consumption.Fall behind in the Rural areas Economic development, per capita income is lower, and in the few situation of arable area, the laying of traditional sewage collecting pipe network and sewage pumping equipment and operation and maintenance cost are for the Rural areas is difficult to accept.
The city domestic sewage concentrated relative to the whole nation processed present situation and compared, the Rural Waste Water in current China overwhelming majority area still is in the state of letting drift, the processing rate of Rural Waste Water is extremely low, according to statistics, the domestic sewage in rural areas by using more than 95% or ight soil draining directly are discharged into underground or rivers,lakes and seas.Therefore, in recent years, the pollution effect of Rural Waste Water has surmounted the scope of local and point source, develops into basin-wide pollution problem, brings very big impact for the water body environmental capacity.
The normal method that adopts of existing dirty water living creature processing technique has anaerobic biological treatment, activated sludge process, biomembrance process etc.Its principal character is particularly bacterium of using microbe, and for giving full play in the custom-designed biochemical reactor of microbial process, the pollutent in the waste water is converted into microorganism cells and simple inorganics.In existing sewage disposal, brought into play vital role.Anaerobic biological treatment is mainly for the processing that is applicable to high concentrated organic wastewater, the residence time is longer, all kinds of Pollutant levels are still higher in the water outlet, and the Rural Waste Water organic content is totally lower, just so that anaerobic biological treatment is processed in Rural Waste Water great limitation arranged.Activated sludge process is the topmost method of conventional B-grade sewage treatment plant, and conventional B-grade sewage treatment plant pollutes at the control Sewage Environment is also having significant limitation aspect the control.At first the weakness of this method maximum is to produce a large amount of active sludge, and active sludge will cause serious secondary pollution as can not get effective processing, and excess sludge has become the bottleneck of activated sludge process development.Secondly it can only effectively be removed in biodegradable organism (usually with BOD), and can not effectively remove the organism (usually in COD) of difficult degradation, more can not effectively remove the trophicity salt such as nitrogen, phosphorus.The many subsequent processes of processing as anerobic sowage of biomembrance process are in order to improve water quality.The membrane bioreactor design and operation is simple, technical maturity, but use all is difficult to obtain good treatment effect separately, but mainly have at present the problems such as running cost is higher, system's running maintenance is comparatively complicated.
