垃圾高效反应器对农村生活垃圾的降解研究

Study on Degradation of Rural Domestic Refuse by High Efficiency Reactor

以江苏铜山区潘塘街道办事处下辖3个行政村生活垃圾为对象,设计了厌氧型垃圾生物反应器,研究了农村生活垃圾在反应器中的变化情况。研究表明:潘塘村和姜楼村生活垃圾中含有大量的水分和蛋白质,促进了厌氧微生物的生长繁殖,推动甲烷气的产生,使渗滤液p H值迅速上升,30周p H达到最高点8.24和8.33。初期反应器中BOD浓度,3个行政村都呈上升趋势,16周左右达到最大值,30周后赵店村、潘塘村、姜楼村3个行政村渗滤液中BOD浓度分别下降到26101mg/L、16121mg/L、20105mg/L。

Based on the domestic waste the anaerobic bioreactor was designed from three administrative villages in Tongshan,Jiangsu Province,and the changes of rural domestic refuse in the reactor were studied.Research shows that:contained a lot of waterand protein,Pan Tang and Jiang Lou garbage,promotes the anaerobic microbial growth and reproduction;promotes the generationof methane gas;the leachate pH value increased rapidly;30weeks to reach the highest point of8.24and8.33pH.The initialconcentration of BOD in the reactor,three administrative villages have increased about16weeks,reached the maximum after30weeks of the three administrative villages,Zhao Dian,Pan Tang,Jiang Lou in leachate BOD concentration decreased to26101mg/L,16121mg/L,down to20105mg/L.
