【摘要】 研究了以炉渣、陶粒、核桃壳为填料的三种变速厌氧滤池处理城市污水的工况,交对影响反应器性能的因素作了分析。结果表明,在负荷2.31和4.54kgCOD/m~3·d下,三种滤池的出水COD均<100和150mg/L,分别达到国家有关排放标准。更多还原

【Abstract】 A process for treating municipal sewage by three different variable - velocity anaerobic biofilters with various media(walnut shell,cinder and ceramsite)is studied,and factors affecting reactor performance are analysed in this paper. The results show that effluent COD concentration is less than 100mg/L when organic loading rate is at 2. 31kg COD/m3 ·d,whereas effluent COD concentration is less than 150mg/L when at 4. 54kg COD/m3 · d.更多还原
