Urbanization, economic growth, and the continuing improvement in living standards have all contributed to the increase of municipal solid waste. More effective technology is needed to improve the conditional landfill of municipal solid waste. Multifunctional microbe community introduced in bioreactor landfill accelerates the degradation of leachate of MSW( Municipal Solid Waste). The results show that introduced microbes shorten the acid formation phase effectively, 208 days earlier than contrast group; introduced microbes accelerated the degradation of leachate. Concentration ofCODof leachate decreases significantly and remains 3000mg/Lafter 505thday, 187 days earlier than contrast group. Concentration of ammonia nitrogen of leachate decomposes more rapidly (63 days earlier) and finally reaches 0.025g/Lat 700thday that meets the national pollution - control requirements of MSW (GB 16889-2008).
