New Water Treatment Chemical PFZSS Preparation and Application

摘要

Nowadays global water quality pollution has become extremely serious, and solving water pollution has beenextremely urgent, so researches on water pollution solutions have become even urgent. And flocculating method is themost traditional water purification method, research and create new high performance flocculating agent is one of flocculatingmethod inherent problems. The paper mainly describes adding iron, zinc two kinds of metal captions together inpolysyllabic acid, well controlling all aspects requirements in technology, researching and creating new water purificationsubstance—poly iron and zinc silicate sulfate flocculants (PFZSS). PFZSS making method is weighting proper amountsodium silicate into container, and meanwhile putting it into water to dissolve, then utilizing dilute euphoric acid and sodiumhydroxide to adjust silicic acid solution pH value and arrive at regulated scope, letting it to activate and arrive at certaintime, slowly importing activated proper silica acid solution into moderate iron sulfate and zinc sulfate on the conditionof fully blending, and finally putting and curing for a while. And implement experiment research on how mixed solutionmetal cations matching; making method, pH value, and silicon dioxide concentration these factors affect PFZSSoverall performance. PFZSS application mainly takes catering industry sewage solution as an example to get PFZSS hasvery strong absorption capacity, owns good cleaning effects on extremely turbid catering industry treatment sewage CODand turbidity acquiring, its reaction formed flock density is great, sedimentation rate is very fast, so PFZSS will have greatapplication prospects in the aspect of treating urban sewage.
