| 摘 要： | 目的]探索适于滇池疏浚底泥脱水的工艺参数。方法]借鉴污水处理厂中污泥的处理方法,采用絮凝剂FeCl3、Al2（SO4）3和PAM作为脱水药剂,通过向疏浚底泥中投加絮凝剂进行试验研究。结果]Al2（SO4）3比FeCl3和PAM的脱水效果好,每升滇池疏浚底泥样品中Al2（SO4）3的最佳投加量为170 mg,上清液可达到GB18918-2002的一级B标准,可直接排放至自然水体而不会造成污染。结论]该研究可为滇池疏浚底泥快速脱水提供一条简易可行的途径,便于底泥的处置及资源化利用。

| Abstract: | Objective]The technological parameter suitable for the dewatering of dredged sediment in Dian Lake was studied.Method]By means of the treatment method of sewage sludge in sewage treatment plant,flocculants including FeCl3,Al2(SO4)3 and PAM were taken as dewatering agents which were added in dredged sediment.Result]The results showed that Al2(SO4)3 had better dewatering effect than FeCl3 and PAM,and the optimum dosing quantity of Al2(SO4)3 in dredged sediment was 170 mg/L,in addition,the supernatant could meet the first class B standard of GB18918-2002 and be discharged directly to nature water without pollution.Conclusion]Our study could provide a simple and feasible way for the rapid dewatering of dredged sediment in Dian Lake,which would be convenient for the disposal and resource utilization of dredged sediment. |
