Research On Co-landfilling Of Lime Mud From Paper-making And Municipal Solid Waste

In this paper, the experiment with the ingredients of lime mud from paper-making to explore the possibility of co-landfilling of lime mud and municipal solid waste (MSW). Lime mud eliminate use of paper refuse in the process of degradation of organic acid accumulation phenomenon, to avoid "over acid condition", to accelerate the process of anaerobic degradation.Making Lime mud from paper-making and municipal solid waste (MSW) co-landfilling according to the principle of two different proportion but equal total dry weight, by simulating the real landfill waste decomposition conditions, regularly monitor the leachate in the two devices for a period of37days in order to study the influence on the content of lime mud from paper-making to MSW.The experiment indated that add a certain amount of Lime mud from paper-making in the process of co-landfilling. the conductivity, salinity. TDS, ammonia levels of leachate water would all rise, and the content of COD would reduce. At last,the experiment achieved the desired effect.Therefore, we can infer that adding the right amount of lime mud from paper-making could accelerated the process of anaerobic degradation, and could improve the effect on waste degradation. The study provides a viable way for the comprehensive utilization.
