The addition of MCMP had not only ensured the water quality of treated effluent to be up to first-class B of "Discharge standard of pollutants for municipal wastewater treatment plant"(GB18918-2002), but also achieved the removal of N and P effectively. Based on surveying the content of heavy metals, the T-Hg is about 81% higher, the TAs is about 110% higher, the TNi is 46% higher, the TK is 24% higher, the TP is 7% higher, the TCr is 64% lower, the TN is 29% lower. The MLVSS/MLSS is lower. The SVI value is from 19.3 to 26.23. This method needed no changes for wastewater treatment process and operation pattern, the extra consumption of power was also needlessness.

但同时发现，总汞较试验前提高81%，总砷较试验前提高110%，总镍较试验前提高46%，总钾较试验前提高24%，总磷提高7%；总铬较试验前减少64%，总氮减少29%，污泥的MLVSS/MLSS值略有降低，SVI值从19.3增加到26.23，为了保证排放的污泥中重金属含量不超标，在以后的实际生产运行中，需要定期以排泥形式排出含重金属等污染物的污泥，以保证污水处理的正常运行。
