摘　　要：采用CASS工艺协同处理高盐榨菜废水与城镇污水,研究了除磷剂对污泥活性及絮体结构的影响。结果表明:聚合硅酸铁、氯化铁和硫酸铝的投加改善了污泥的絮体结构,提高了污泥絮体的密实度;聚合硅酸铁、氯化铁和硫酸铝对异养菌和硝化菌的OUR及污泥脱氢酶活性影响较小,硫酸铝对亚硝化菌OUR的影响明显强于聚合硅酸铁和氯化铁。The CASS process was used to treat high-salinity mustard tuber wastewater and municipal wastewater. The effect of phosphorus removing agents on sludge activity and floe structure was investigated. The results showed that the addition of polysilicate ferric, ferric chloride and aluminum sulfate improved structure and density of sludge floes. The three kinds of phosphorus removing agents above had little effect on OUR of heterotrophic bacteria and nitrifying bacteria and sludge dehydrogenase activity. The effect of aluminum sulfate on OUR of nitrite bacteria was significantly stronger than that of polysilicate ferric and ferric chloride.
