摘要
对某城市污水厂污泥采用PAFC与PAM复合絮凝剂进行脱水调理试验,污泥含水率可从91.8%降至86.8%,污泥体积则由原先的45%降至28%。复合药剂无机与有机的最佳配比(质量比)为100∶1;而且在相同的处理条件下,采用复合絮凝剂不但较大幅度提高处理效果,而且药剂成本比单一采用无机药剂有所降低。
The dehydration test was applied to treat the municipal sewage sludge with PAFC and PAM,and the moisture content of sludge could reduce from 91.8% to 86.8%,sludge volume could reduce by the original 45% to 28%.The best ratio of compound coagulant was 100,and under the same processing conditions,using compound coagulant,not only greatly improved treatment effect,and coagulant cost was reduced than single.
