针对东湖风景区湖底淤泥含水量高，重金属镉、汞、铅、砷等含量超标，氮、磷含量高的情况，采用脱水固结一体化工艺结合FSA泥沙聚沉剂和HEC高强高耐水土体固结剂进行处理，处理后泥饼及尾水含水率、重金属含量等都达到了相关标准。处理后泥饼可作为农业、园林用土及填方材料，尾水可达到直接排放标准。

According to the high water content of sublacustrine silt and over standard of cadmium, mercury, plumbum and arsenic, dehydration-consolidation integrative construction technique combined with FSA sediment coagulant agent and HEC soil mass solidifying agent was adopted for treatment. Each index can reach the requirement after treatment, the mud cake can be used as agricultural soil and filling material, tail water can reach the discharge standard.
