| 摘 要： | 对粪便废水絮凝处理的药剂进行了初步筛选,选定常用絮凝剂硫酸铝、聚合氯化铝和聚丙烯酰胺(包括3种类型)进行了单独絮凝和复配絮凝的实验研究,优选出最佳絮凝剂.结果表明:对于500 mL水样,在pH 7.5、0.2%硫酸铝投加量8 mL、0.2%PAM(阳离子型,分子质量1 500万u)投加量1.5 mL的条件下,废水的色度、浊度、CODCr的去除率分别达到94.3%、96.0%和58.2%,絮凝效果较理想.

| Abstract: | Flocculants for treating night soil wastewater were selected primarily. AS,PAC and PAM(including 3 types),which were used commonly, were chosen to flocculate singly and together. Best flocculants were determined at last. The result showed that for 500 mL of water sample, when pH was adjusted to be 7.5,8 mL of AS and 1.5 mL of PAM(cation, M=15 million u)whose concentrations were both 0.2% were used,removal rate of chroma,turbidness and CODCr could be up to 94.3%,96.0% and 58.2% respectively. The effect of flocculation treatment was ideal. |
