Description
Technical field
The invention belongs to water-treatment technology field, relate to a kind of flocculating agent composition and application thereof.
Background technology
The coagulating treatment of water is one of key link in wastewater treatment, turbid scrubbing can be gone, reduce the pollution load of sewage subsequent disposal, and flocculation agent is the key factor determining coagulating treatment effect, all has material impact to the operation conditions of follow-up flow process, final outflow water water quality and cost etc.
Flocculation agent can be divided into inorganic flocculating agent and organic floculant two class according to its Chemical Composition, wherein, inorganic flocculating agent can be divided into low molecule flocculation agent and polymeric flocculant again, low molecule flocculation agent is as the aluminium such as Tai-Ace S 150, aluminum chloride salt system and the molysite such as iron(ic) chloride and ferric sulfate system, low molecule flocculation agent cost is lower, but, the shortcomings such as flocculation sediment speed is slow, medicine consumption is high that it has; Polymeric flocculant, as aluminum chloride hydrocarbon complex (PAC), polyaluminium sulfate, bodied ferric sulfate etc., overcome the shortcoming that the processing efficiency of low molecule flocculation agent existence is low, but its cost is higher, and treatment effect is poor when low-temperature and low turbidity.Organic floculant is generally high molecular polymer, as polyamine flocculation agent, Quaternary Ammonium Starch base flocculation agent and polyacrylamide flocculant etc., wherein, polyacrylamide has the advantages such as the pH value that consumption is few, primary water mass-energy power is strong, flocculation rate soon, is not subject to water affects, the sludge quantity of generation is few and is applied widely, but polyacrylamide has strong neurotoxicity and certain carinogenicity, large weight polyacrylamide remains for the treatment of producing polymer during waste water, destroy aqueous bio chain, and then have influence on human health.
CN1393410A discloses a kind of Inorganic whisker type flocculation agent and production method thereof, this kind of flocculation agent comprises the polymkeric substance of Dicyanodiamide and formaldehyde, Polyaluminium Sulfate Chloride and/or Polyaluminium Sulfate Chloride calcium, prepare by the following method: first by aluminium salt hydrolysis, then in described hydrolysate, add calcium salt and carry out polyreaction, add again after Dicyanodiamide and formaldehyde carry out polycondensation and obtain described Inorganic whisker type flocculation agent, it is low that this flocculation agent has medicine consumption, the advantages such as good waste water treatment effect, but this flocculation agent take formaldehyde as raw material, production process easily produces environmental pollution, also containing a large amount of free formaldehyde in the flocculation agent obtained, be detrimental to health.
CN102295335A openly knows clearly a kind of flocculating agent composition, comprising: the ferrate of 1wt% ~ 10wt%; The poly-aluminum calcium chloride of 20wt% ~ 50wt%; The aluminum contained compound of 10wt% ~ 40wt% and/or calcium containing compound; The iron(ic) chloride of 5wt% ~ 25wt% and the polyacrylamide of 1wt% ~ 20wt%.When flocculating agent composition usage quantity provided by the invention is 0.6g/L, be that in the sanitary sewage of 300mg/L ~ 400mg/L, turbidity removal rate can reach more than 93% to COD, the clearance that total tp removal rate can reach more than 90%, COD can reach more than 31%.But the consumption of flocculating agent composition is higher when disposing of sewage in the present invention.
