Abstract
The invention relates to a preparation method of a compound coagulant. The compound coagulant is prepared by commonly mixing polyaluminium chloride, diallydimethylammonium chloride (the viscosity is 8,000-12,000), magnesium sulfate, polyferric chloride and deionized water according to the mass ratio of 30 percent, 2 percent, 5 percent, 1 percent and 62 percent. The invention has the advantages of removing heavy metals and organisms in an organic complex by multiple actions, having the effect of decolorization, wide medicine effect range and simple and convenient operation and replacing a plurality of coagulants for use.
Description
Technical field
The present invention relates to a kind ofly has good effect of removing to heavy metal in the Waste Water Treatment, organic matter removal compound coagulant and to complex compound, relates in particular to a kind of compound method of compound coagulant.
Background technology
Continuous development along with wastewater treatment new technology and waste water recycling technology; The application of coagulant in water treatment more and more widely; And the continuous complicacy at waste water water source is normally moved the higher requirement of proposition with deterioration to existing treatment system; And along with the mark of carrying of national water quality discharging, the water outlet of the water treatment system first obstacle that also becomes its operation not up to standard, how reducing and removing heavy metal and organic matter in the waste water becomes in the present industry field research direction of concern the most.Mainly lean on traditional medicament to handle to these pollutants by regulating methods such as ph, redox; Thereby heavy metal and organic matter 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 all kinds of materials are removed effect completely; After can through introduce coagulant, flocculation aid helped; Available coagulation flocculation aid (aluminium polychloride, PAFC 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
To above defective, the present invention provides a kind of and removes that organic matter heavy metal effect in the water is preferable, the drug effect scope wide, can replace the compound method of the compound coagulant that various medicaments uses, thereby solves the problem in the sewage.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of compound method of compound coagulant, its preparation method comprise that mainly aluminium polychloride, PDDA (viscosity is 8000-12000), magnesium sulfate, poly-ferric chloride and deionized water composition are respectively 30%, 2%, 5%, 1% and 62% mixed together according to the quality proportioning and form.
The beneficial effect of the compound method of compound coagulant of the present invention is: remove heavy metal and organic matter in the organic complex through multiple action, also have the effect of decolouring, the drug effect scope is wide; Can replace multiple coagulated agent to use, easy and simple to handle.
