Description
Technical field
The present invention relates to living drainage processing technology field, particularly relate to the preparation method of one way of life drainge treating agent.
Background technology
The sewage produced during human lives, is one of the primary pollution source of water body.Mainly feces and wash water.Containing large amount of organic in sanitary sewage, such as cellulose, starch, saccharide and fat protein etc.；The most often contain pathogen, virus and parasitic ovum；The chloride of inorganic salts, sulfate, phosphate, bicarbonate and sodium, potassium, calcium, magnesium etc..Total feature is nitrogenous, sulfur-bearing and phosphorous height, under anaerobic bacteria effect, easily gives birth to odorant.Existing sanitary sewage disposal material has, bodied ferric sulfate, is a kind of inorganic polymer coagulant water-purifying material developed on the basis of aluminium salt and iron salt coagulation Hydrolytic Mechanism.According to Synergistic principle, add the new and effective coagulant of one that fe ion or ferric oxide are composited with other iron containing compounds.Aluminum sulfate, not easy-weathering and lose water of crystallization, more stable, heating can dehydration, high temperature can be decomposed into aluminium oxide and sulfur oxide.Aluminium hydroxide is generated after hydrolysis.Aqueous solution seethes with excitement for a long time and can generate basic aluminium sulphate.Industrial goods are canescence lamellar, granular or block, because of the band light green containing low iron salt, make surface turn to be yellow because low price iron salt is oxidized again.Crude product is canescence aplitic texture cellular thing.Nontoxic, dust can stimulate eyes.Aluminium polychlorid, sewage disposal aluminium polychlorid special increase temperature extends the response time, make whole Molecularly Imprinted Polymer structure the hugest, crane span structure distribution is the most reasonable, so that having higher absorption affinity and cohesiveness, being the first-selection of medicament used by Industrial Wastewater Treatment, it can decline to a great extent cost of water treatment.Polyacrylamide, on the premise of reaching equal water quality, polyacrylamide as flocculation aid and other flocculant (the most inorganic or organic coagulants) with the use of, the usage amount of flocculant can be substantially reduced.Improve water quality.In the processing procedure of drinking water treatment and industrial wastewater, polyacrylamide uses with inorganic coagulant, can obviously improve effluent quality.These inorganic agents, can only Cucumber in single treatment sewage owing to using monistic chemical substance, it is difficult to reach the purpose of integrated treatment, it is also difficult to remove the float in sanitary sewage, BOD and COD simultaneously.
Summary of the invention
The purpose of the present invention is aiming at the defect of above-mentioned existence and provides the preparation method of one way of life drainge treating agent.Multiple biological raw material is prepared as living drainage inorganic agent, effective, low cost, it is suitable for large-scale production.
1. the present invention provides the preparation method of one way of life drainge treating agent, and step is as follows:
