With the urban sewage treatment capacity and treatment rate continues to improve, along with the amount of sludge generated is also increasing. Sludge is usually high water content, perishable, fetid, toxic substances, and a large number of harmful pathogens, the importance of timely treatment and disposal. The landfill, incineration and land use sludge treatment technology because of its need to take up a lot of land to produce secondary pollution and costly pretreatment increasingly restricted. Therefore, the source of the sludge treatment should begin, fundamentally, in essence, to reduce the amount of sludge, sludge reduction technology came into being. 1990s proposed sludge reduction concept to sludge reduction for the purpose of the entire wastewater treatment system of increasingly widespread. Various countries around the world continue to expand sludge reduction of new technology, new technology research and application. This article focuses on the sewage treatment aerobic reaction directly dosing MCMP-Ⅱ multifunction microbial agents, through microbial enhanced, enzymes, biodegradation, extended sludge age, improve sludge concentration, biological predation and uncoupling United metabolism role in achieving the sludge reduction feasibility and operability. In Chongqing, a sewage treatment plant for the production of experimental research, the testing process, directly in the aerobic reaction zone dosing MCMP-Ⅱ multifunction microbial agents to combine with existing activated sludge, without increasing the dedicated processing Facilities unit, nor alter the original treatment facilities. The results showed that: adding a MCMP-Ⅱ multifunction microbial agents, the sewage treatment plant operating parameters based upon the original run, do not change the original operation mode, aeration exactly the same, without increasing power consumption, nor impact of sewage treatment plant effluent quality. The sewage treatment plant sludge is still in negative growth, sludge reduction effect is much better than before the test to determine the sludge reduction rate of 80% or more goals. Through the sludge reduction, you can also get good economic, environmental and social benefits. It is evident that the sewage treatment plant aerobic biological treatment section dosing MCMP-Ⅱ multifunction microbial agents for sludge reduction is a very effective method. And fully validated multifunction microbial agents (MCMP-Ⅱ) in respect of the various characteristics of sludge reduction, to obtain various operating parameters for future application to provide a reliable scientific basis.
