Sulfuric Acid Burning Slag Flocculant Prepared PPFS And Application In Wastewater Treatment

This article from the sulfuric acid slag current burn and recycling began to burn, discusses the harm of sulfuric acid slag, survey the current burn slag main utilization way, and on this basis, and carried out the sulfuric acid burning slag flocculant prepared in wastewater treatment research.Reduced under certain condition and soaked in the acid, Price will be three iron(Fe³⁺) restore for two price iron (Fe²⁺), put the Three price iron (Fe³⁺)restore the two price iron(Fe²⁺), then with sulphuric acid-which price will be two iron analysis sulphuric acid-which so that come to have the iron solution (FeSO₄), In the catalyst, the oxidizing, water and aggregate function of the aggregate hydrous iron (PFS).The emphasis on research in this experiment, to make the best conditions for PFS (liquid) reached a level with the class of country standardOn the basis of the PFS which changing nature , to gain the flocculation of more effectful. By introduced PO43-,and PFS be made by improving . As the role of the bridge, Process of Poly Ferric Sulfate is more reforcing than PPFS. The article is study on the optimum physics experiments condition during the changing fuction and nature. With sulphuric acid-which to cope with the urban sewage and waste water, and studying for the main coagulant usage for COD, degrees,NH₃-N,TP,SS, in effect, and find out the optimum dosage.Finding in the subject, we have the optimum physics experiments condition for the aggregation of sulphuric acid-which iron, the best experiment have been aggregated hydrous iron process. Be researching by the aggregate hydrous iron which to change nature and using to deal with the effect of water.
