Abstract
The invention discloses a kind of preparation methods of living drainage inorganic agent to prepare living drainage inorganic agent by being mixed again with other auxiliary agents after being handled a variety of biological raw materials, it is easy to operate, the living drainage inorganic agent prepared is at low cost, and effect is good, is suitble to large-scale production.Living drainage inorganic agent prepared by the method for the present invention, it be 90% or more, COD removal rates is 90% or more that living drainage removal efficiency, which reaches 95% or more, BOD removal rates, after processing.
Description
Technical field
The present invention relates to living drainage processing technology fields, more particularly to a kind of preparation side of living drainage inorganic agent
Method.
Background technology
The sewage generated during human lives, is one of primary pollution source of water body.Mainly excrement and wash water.
Contain large amount of organic, such as cellulose, starch, carbohydrate and fat protein in sanitary sewage；Also often containing pathogen, virus
And parasitic ovum；Chloride, sulfate, phosphate, bicarbonate and the sodium of inorganic salts, potassium, calcium, magnesium etc..Total feature is
Nitrogenous, sulfur-bearing and phosphorous height, in the case where anaerobic bacteria acts on, easily raw odorant.Existing sanitary sewage disposal substance has, polymerised sulphur
Sour iron is a kind of inorganic polymer coagulant water purification material that developed on the basis of aluminium salt and molysite coagulation Hydrolytic Mechanism
Material.According to synergistic principle, it is new that one kind that simple substance iron ion or ferric oxide and other iron containing compounds are combined is added
Type coagulant.Aluminum sulfate, not easy-weathering and lose the crystallization water, it is more stable, heating can dehydration, high temperature can be decomposed into oxidation
Aluminium and sulfur oxide.Aluminium hydroxide is generated after hydrolysis.Aqueous solution boils for a long time produces basic aluminium sulphate.Industrial goods are ash
It is white plates, granular or blocky, so that surface is turned to be yellow with light green, and because low price molysite is aoxidized due to containing low molysite.Crude product
For canescence aplitic texture cellular object.Nontoxic, dust can stimulate eyes.Aluminium polychloride, sewage disposal aluminium polychloride
Special increase temperature extends the reaction time so that and entire Molecularly Imprinted Polymer structure is more huge, and crane span structure distribution is more reasonable, so that
There are stronger adsorption capacity and cohesiveness, be the first choice of medicament used in Industrial Wastewater Treatment, it can decline to a great extent cost of water treatment.It is poly-
Acrylamide, under the premise of reaching same water quality, polyacrylamide is as flocculation aid and other flocculants（It is mainly inorganic or
Person's organic coagulants）It is used cooperatively, the usage amount of flocculant can be substantially reduced.Improve water quality.In drinking water treatment and Industry Waste
In the processing procedure of water, polyacrylamide is used with inorganic coagulant, can obviously improve effluent quality.These inorganic agents are due to adopting
With monistic chemical substance, Cucumber that can only be in single treatment sewage, it is difficult to achieve the purpose that integrated treatment, it is also difficult to
The suspended matter in sanitary sewage, BOD and COD are removed simultaneously.
