菲律宾蛤仔黏附污泥已被报道为一种新型的天然生物絮凝剂,适合淡水处理和海水处理.本文探究了菲律宾蛤仔黏附污泥在实际废水处理中的应用效果.结果表明:菲律宾蛤仔黏附污泥作为絮凝剂可以有效去除废水中悬浮物(SS),去除率可达49.3%,并能有效改善膨胀的活性污泥的沉降性能,促进光合细菌的挂膜,促进率为33.3%;另外,其还有效吸附去除水中的重金属,当重金属离子Cd2+、Zn2+、Cu2+的浓度分别为5.09 mg/L、14.09 mg/L、255.81 mg/L时,去除率分别达72%、67%、92%.%Ruditapes philippinarum conglutination mud (RPM) has been reported as a new type of natural bioflocculant for freshwater treatment and seawater treatment. In this study, RPM will be used as a research object to explore its treatment effect in actual wastewater. The research results were showed as follows: RPM could be used as a bioflocculant to remove SS from the wastewater, with a removal rate of 49.3%, and the set-tling property of bulking activated sludge was improved effectively. RPM could also promote the biofilm build-ing of photosynthetic bacteria, with a promoting rate of 33.3%. Furthermore, it could effectively remove heavy metals from wastewater, when the concentration of Cd2+, Zn2+and Cu2+were 5.09 mg/L, 14.09 mg/L, 255.81 mg/L, the removal rate could reached 72%, 67%, 92% respectively.
