Abstract: Based on the domestic waste of three administrative villages in Tongshan of Jiangsu,the anaerobic bioreactor was designed,and the changes of rural domestic refuse in the reactor were studied.The research shows that the three administrative villages of garbage in the heavy metal content is higher in the early stage of content,with the reaction time into methane producing period,its content decreased rapidly,the reflux equipment through percolate treatment,the percolate Cr,Mn,Cd,Cu concentration decreased significantly in later stage.Contains a lot of water and protein,Pan Tang and Jiang Lou Village garbage,promote the anaerobic microbial growth and reproduction,promote the generation of methane gas,the percolate pH value increased rapidly,30 weeks to reach the highest point of 8.24 and 8.33 pH.But Zhao Dian Village due to great loss of garbage percolate,a large number of organic acids produced by microbial acidification phase decomposition is slow,long time of pH in a low range.
