摘要
通过烧杯试验,分别对Al2(SO4)3·18H2O,Fe2(SO4)3,聚合Al2O3以及1:1组合无机絮凝剂(Al/Fe)对高浓度垃圾渗滤液的除磷效果进行了研究,结果表明当pH值相同,静沉50min,投药量为700mg/L时,1:1组合絮凝剂的除磷效率高于单独使用无机絮凝剂,TP去除率为95.12%。处理后出水TP浓度小于1.5mg/L,达到GB16889-2008一级标准。
TAluminum sulfate, ferric sulfate, poly aluminum oxide and 1：1 combination of two inorganic flocculants were chosen as coagulants; the phosphorus removal effect of high concentration landfill leachate by beaker experiment was carried out. The results showed that, when the dosage was 700mg/L, setting time was 50min in the same pH value, the removal effect of TP was 95.12%, and the TP removed by 1：1 combination floeculants was higher than the two inorganic flocculants used alone. The concentration of TP was lower than 1.5 mg/L after treatment, which is up to the primary standard of GB16889-2008.
