Acceleration of the Degradation of Leachate with Introduced Microbes in Bioreactor Sanitary Landfill

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 of COD of leachate decreases significantly and remains 3000 mg/L after 505th day, 187 days earlier than contrast group. Concentration of ammonia nitrogen of leachate decomposes more rapidly (63 days earlier) and finally reaches 0.025 g/L at 700th day that meets the national pollution - control requirements of MSW (GB 16889-2008).
