化学-混凝沉淀法处理酸性高浓度含氟光伏废水OA北大核心CHSSCDCSTPCD
Treatment of acidic and highly concentrated fluorine-containing photovoltaic wastewater by chemical coagulation-precipitation method
研究常用钙源沉淀剂对出水pH和溶解性总固体(TDS)的影响,优选出最佳钙源沉淀剂,在此基础上研究化学-混凝沉淀法对某光伏废水中高浓度F-的去除效果.结果表明:CaCO3沉淀剂不仅能有效去除F-并减少TDS,还能使处理后的废水pH接近中性;相较于聚合氯化铝(PAC)和聚合氯化铝铁(PAFC),使用FeCl3作为混凝剂的投加量较少;投加聚丙烯酰胺(PAM)助凝剂可以强化混凝效果,缩短沉淀时间.CaCO3投加量(钙氟摩尔比)为0.8时,F-质量浓度从6…查看全部>>
The effects of common calcium source precipitants on effluent pH and total dissolved solids(TDS)were investigated,and the optimal precipitant was identified.Based on this,the effect of chemical coagulation-precipitation method on the removal of high concentrations of F-from photovoltaic wastewater was studied.The results showed that the CaCO3 precipitant could not only effectively remove F-and reduce TDS,but also bring the pH of the treated wastewater close …查看全部>>
