Description
Technical field:
The present invention relates to the high-concentration culture technical field of sewage, specifically is to make it reach scale pig farm sewage water treatment method and integrated-type equipment thereof that " livestock and poultry breeding industry pollutant emission standard " requires after a kind of pig farm sewage directly can the processing.
Background technology:
Large scale of pig farm field sewage is a most typical pollutant in the aquaculture waste, and it mainly comprises pig urine, part pig manure and pig house wash-down water, belongs to high concentrated organic wastewater.Because described large scale of pig farm field sewage is the important source of aquaculture environmental pollution, therefore, how large scale of pig farm field sewage being carried out harmless treatment has become scale pig farm aquaculture in recent years and has been badly in need of the problem researched and solved.
At present, the sewage harmless treatment of scale pig farm mainly contains also field processing, handles naturally and three kinds of tupes of industrial treatment, wherein, also the field tupe is a kind of traditional, cost-effective method of disposal, it is that fecaluria, wash-down water are imposed in the soil, organic substance is decomposed changes into soil ulmin and plant growth factor, and organonitrogen phosphorus changes into inorganic nitrogen phosphorus, thereby realize the recycle of nutrient, reach zero release of pollutant.But this pattern only is applicable to away from the city, and the soil broadness has the dissolve large scale of pig farm field of fecal sewage, enough farmlands.What the nature tupe adopted is natural treatment systems such as oxidation pond, artificial swamp.Although natural tupe also can reach the similar also effect of field tupe; but it also can only be applicable to away from the city; the large scale of pig farm field of soil broadness particularly has beach, wasteland, forest land or bottom land can do the large scale of pig farm field of sewage natural treatment system.
Along with increasing progressively day by day of population, soil in short supply day by day, the industrial treatment pattern is progressively replacing the status of going back field tupe and natural tupe, its reason just is, the enforcement of industrial treatment pattern need not to rely on a large amount of farmlands fecal sewage of dissolving, and also need not to rely on beach, wasteland, forest land or bottom land and makes the sewage natural treatment system.At present, Granted publication number is handled the anaerobic reactor that contains high-concentration suspension solid waste water for the patent of invention of CN1269744C discloses a kind of industrial treatment pattern that adopts, and it is applicable to that Wastewater from Pig Farm, excrement and urine water, excess sludge etc. contain the Anaerobic Digestion of high-concentration suspension solid (high-concentration suspension solid SS is 1%～10%) waste water.This anaerobic reactor is by reactor body, gas extractor, automatic control system and advance, four parts of water exhaust system constitute; Described reactor master ladder is a cylindrical reinforced concrete pond; Described cylindrical reinforced concrete is provided with agitator in the pond; Concrete sump pool wall upper part is set to an annular seal-water tank; Floating bell jar is placed in the annular seal-water tank of pool wall upper end; Gas collection pipe is contained in the floating bell jar center of top; Advance, water-freeing arrangement and pond body connect; Automatic control device is controlled slush pump, agitator and sump pump respectively and is opened and close.Tupe that the disclosed anaerobic reactor of above-mentioned utility model patent adopts and other industrial treatment pattern have a common drawback, be that they can only carry out a kind of processing of strengthening the anaerobic treatment or a certain local unit of pig farm sewage, also can't make water outlet after the processing reach the emission standard of " livestock and poultry breeding industry pollutant emission standard " regulation fully.
Summary of the invention:
The technical problem to be solved in the present invention is, provide a kind of under the situation that need not a large amount of farmlands, beach, wasteland, forest land or bottom land, can carry out effective integrated harmless treatment to scale pig farm sewage, thereby make water outlet after the processing reach the scale pig farm sewage water treatment method of the emission standard of " livestock and poultry breeding industry pollutant emission standard " regulation fully.
Technical solution of the present invention is that a kind of scale pig farm sewage water treatment method that includes following steps is provided:
1., at first make sewage in the cylindrical shell of membrane biological reaction storehouse, carry out biochemical reaction, and make the sewage behind the biochemical reaction flow in the membrane filtration storehouse that directly is communicated with membrane biological reaction storehouse cylindrical shell by a pipeline;
