摘要
测试活性炭、沸石、建筑陶粒以及工程陶粒等四种填料、体积1.23L的生物滤池性能。结果表明,装有工程陶粒的生物滤池其出水无论是COD、NH3-N还是浊度都要低于其他填料。在水力停留时间1.5h,进水COD小于150mg/L时,两种陶粒出水COD均小于25mg/L,而沸石出水COD则达到50mg/L,活性炭出水,为29mg/L。当进水有机负荷为0.74kgCOD/(m3*d)时,工程陶粒出水COD甚至降低到10mg/L以下。
The performances of the 1.23L biofilter filled with activated carbon,zeolite,architecture keramics and engineering keramics are measured.The results show that no matter COD,NH3-N or turbidity,the values from the biofilter with engineering keramics are lower than that with other stuffings.Under the circumstances of HRT=1.5h,COD<150mg/L,the effluent COD from biofilters filled with two kinds of keramics is beneath 25mg/L,whereas COD values from biofilter full of zeolite reaches 50mg/L,and the value from car...
