Activated Carbon With Enhanced Coagulation Associated With Processing The Pilot Study Of The The Xiangjiang Micro-polluted Source Water

Many problems which water source is facing are the problems of water quality ofwater source. The average available water quantity of water source of Per people is lowin China, and the water quality is even worse. By now the tradiontial process oftreatInent of water is not suitable. GAC and Optimized Coagulation are two mature andeffective ways to treat water. And if we unite these them, we will get more advantagesfrom them.This experiment made some prime lab research about the unition of the two ~,processes. It contents:1)jar test of optimized coagulation: to determine the quantity of drug.2)lab experiment of GAC: to find the suitable granual activated carbon to treat theslightIy POlluted Xiang riveL3)production experiment: make use of the dates acquired from lab experiment andjar test to run the model water plant. By contrasting two series of treating PrOcesses, theeffect of "improving GAC perfOrmance by optimized coagulatiod' was investigated.The resuIt indicates: wheIl treating sIightIy polluted source water of Xiang rivet,optimized coagulation will improve the effect of reducing organics remarkably; GAChas good effect in reducing the DBPFP and organics of Xiang rivef, but the effect inreducing DBP is more obviously; the process of "improving GAC by optimizedcoaguIation" can not only has a wonderful result of reduction in DBPPP and organics,but also improve the effect of GAC evident1y and decreasing the caPital cost for a GACfacility; although optimized coagulation increase the quantity of Alum dose, but thelevel of aluminum of treated water will not beyond the standard level; differentprocesses will have different resu1ts in lessening the amount of organics and DBP, sowe should adopt treatment process by considering the requirements of treated wateL...
