| 中文摘要 |
| 在系统分析现有MSW生物反应器型填埋方法优缺点基础上,对其改进,将强制通风好氧和渗滤液循环2种方式有机结合组成新的反应器(称之为反应器A) ,与只有强制通风好氧的反应器(称之为反应器B)作对比.实验过程中对2反应器中NH3、CH4、CO2、pH、温度、电导率及沉降进行控制和监测,对渗滤液中Fe3+和NH4+进行监测与分析,研究2种MSW好氧生物反应器对所填垃圾降解及所产生渗滤液中COD、Fe3+和NH4+的去除效果,探讨两者对所填埋垃圾降解和渗滤液中所测参数去除机理,从而得出反应器A比反应器B对垃圾和渗滤液有更好的降解和去除效果. |
| 英文摘要 |
| Bioreactor landfill is an emerging landfilling method, which represents the newest developing aspect of Municipal Solid Wastes (MSW) treatment. On basis of analyzing the merits and defects of present bioreactor landfilling methods, the paper improves these methods and combines organically aeration and leachate recirculation into a new reactor (called reactor A), which is contrasted with bare aerobic landfill (called reactor B). During the course of experiment, NH3, CH4, CO2, pH, temperature and electric conductivity in the two bioreactors were controlled and detected, meanwhile, COD, Fe3+, NH4+ in the leachate were detected and analyzed. The paper researches on the wastes degradation and the COD, Fe3+ and NH4+ removal of the two bioreacotors, probes into the mechanics of wastes and leachate degradation. Finally the paper draws a conclusion that the effect of degrading wastes and leachate of bioreactor A is better than that of bioreactor B. |
