Abstract
The invention relates to a compound coagulant, which is prepared by jointly mixing the following raw materials by mass percent: 20%-30% of aluminum chloride, 1.0%-2.5% of poly dimethyl diallyl ammonium chloride, 5%-20% of aluminum sulfate, 1%-10% of ferric chloride, 0.03%-0.1% of cation PAM, and 50%-65% of deionized water. The compound coagulant has the beneficial effects that heavy metals and organic matters in an organic complex are removed through multiple actions, and the compound coagulant also has discolored action and a wide drug action range, can substitute a plurality of coagulants and is convenient to operate.
Description
Technical field
The present invention relates to a kind of compound coagulant, belong to technical field of waste water processing.
Background technology
Continuous development along with wastewater treatment new technology and waste water recycling technology, the application of coagulating agent in wastewater treatment more and more widely, and the technology of rare earth exploitation and rare earth deep processing constantly changes improvement, cause the complexity of industry waste water to have higher requirement with the normal operation that worsens existing rare earth processing technology, and along with improving constantly of national water quality emission standard, how the water outlet of the water treatment system first obstacle that also becomes its operation not up to standard reduces and removes heavy metal in the waste water, ammonia nitrogen, indexs such as organism become the research direction of paying close attention to the most in the present industry field.Mainly handle by regulating methods such as PH, redox by traditional medicament at these pollutents, thereby heavy metal and organism in the waste water are spun off from water, but the removal effect of these medicaments is relatively poor, function singleness, drug effect are low, does not have heavy metal, ammonia nitrogen, organic matter removal effect up to standard; After can by introduce coagulating agent, coagulant aids be helped, available coagulation coagulant aids (polymerize aluminum chloride, aluminium iron polychloride etc.) can't satisfy the demands in face of more unmanageable complex compound, and the colourity of use iron salt coagulant water outlet alumen ustum higher, that use aluminum salt to form is more open.
Summary of the invention
At the problem of wastewater treatment in the above-mentioned prior art, the invention provides and a kind ofly can effectively remove the compound coagulant that heavy metal in the waste water and organism, drug effect scope are wide, can replace various medicaments to use.
For achieving the above object, the present invention is by the following technical solutions:
A kind of compound coagulant includes the component of following quality proportioning:
Aluminum chloride 20%-30%, Poly Dimethyl Diallyl Ammonium Chloride 1.0%-2.5%, Tai-Ace S 150 5%-20%, iron(ic) chloride 1%-10%, cationic polyacrylamide (PAM) 0.03%-0.1% and deionized water 50%-65%.
Preferably, the viscosity of described Poly Dimethyl Diallyl Ammonium Chloride is 8000-12000Pas; Described cationic polyacrylamide (PAM) molecular weight 80000-100000.
The quality proportion optimization of each component is: aluminum chloride 25%, Poly Dimethyl Diallyl Ammonium Chloride 1.5%, Tai-Ace S 150 10%, iron(ic) chloride 3%, cationic PAM 0.05% and deionized water 60.45%.
The compound method of compound coagulant of the present invention can adopt the preparation of common composition to be about to the common mixing and stirring of each feed composition and get final product.
Compound coagulant of the present invention can be removed heavy metal (copper, nickel, zinc etc.) in the organic complex and organism especially for the heavy metal organic complex by multiple action, has the effect of decolouring, and the drug effect scope is wide; Can replace multiple coagulated agent to use, easy and simple to handle.
