Analysis Of Water Quality Changes And Influencing Factors Of Village And Town Landfill Leachat

Transfer Station is an important part of waste disposal.Our country environment governs starts late,and governs the work to start from the city,the village and town area is relatively backward.In recent years,with the development of village economy,the income and consumption level of residents are increasing,the output of domestic waste is increasing rapidly,so is the leachate.Although some villages and towns in our country have entered the new rural model,the environment has been improved to a certain extent,but there are still some problems,such as the random piling of garbage in villages and towns,the irregular discharge of leachate,etc..To explore the influencing factors of the change of water quality and quantity and the present situation of the disposal of the landfill leachate in villages and towns can provide a new idea for the further improvement of the treatment of the garbage in villages and towns.In this paper,the seasonal sampling,detection,investigation and analysis of leachate from village and township Transfer station in different areas were carried out.The results showed that leachate from village and township leachate was acidic,and its biodegradability was generally poor,high concentrations of nitrogen and phosphorus and heavy metals affect the growth of microbial community.At the same time,due to the economic and geographical environment of villages and towns,the infrastructure construction of villages and towns and the refuse collection and transportation system are not complete and sound,and the existing disposal equipment is not feasible in the Transfer station of villages and towns.Leachate quality and quantity fluctuated seasonally due to seasonal variations,changes in residents’ lifestyles and irregular Transfer station operations.The leachate of village and township Transfer station is disposed of mainly by discharging into the surrounding environment or merging into the municipal sewer network.However,due to the long storage time and high concentration of leachate before discharge,the random discharge of leachate may affect the environment around the transfer station and put pressure on the municipal sewer system.
