生物滤池的运行原理
不同规模的生物滤池,其最佳生物量的控制方法不同。对于小型生物滤池(横截面积为0.004~0.015m2),回流水冲洗法的效果较佳;而对于大型生物滤池(横截面积>0.09m2),搅拌法的效果较优。回流水洗法对生物量的去除率随着洗涤温度(30~60℃)的增加而增大;回流碱洗较回流水洗可更快地去除多余的生物量,但是滤池恢复稳定的时间较长。

生物滤池的运行原理

不同规模的生物滤池,其生物量的控制方法不同。对于小型生物滤池(横截面积为00040015m2),回流水冲洗法的效果较佳;而对于大型生物滤池(横截面积>009m2),搅拌法的效果较优。回流水洗法对生物量的去除率随着洗涤温度(3060)的增加而增大;回流碱洗较回流水洗可更快地去除多余的生物量,但是滤池恢复稳定的时间较长。

生物滤池的运行原理

搅拌、回流水洗可有效去除多余的生物量(去除率>80)且不影响滤池的运行,但是耗能较大;逐渐减少氮供给对生物量的去除率(60)及压降的控制效果均不佳;周期变换氮浓度可有效控制生物量,使压降<022kPam

①生物滤池是去除低浓度硫化氢VOCs的有效方法。对硫化氢的去除主要与滤料的吸附/吸收作用有关;生物降解在VOCs的去除中起主导作用;当同时去除多种气体时,需考虑气体间的相互作用对去除率的影响。②复合滤料既可为微生物代谢提供丰富的营养物质,又可解决压降问题,有利于维持滤池稳定、降低运行成本及操作难度,因此在实际应用中建议使用复合滤料。③在一定范围内,对气体的去除率随滤料含水率的增加而增大;控制滤料含水率可采用进气预喷淋加湿和填料喷淋加湿相结合的措施。④延长EBRT可增大对硫化氢,特别是疏水性VOCs的去除率,但EBRT过长容易造成有害介质在生物滤池中累积,且会增加能耗。⑤可以采用物理方法、化学方法、生物方法、改善生物滤池的没计和运行参数等途径控制生物滤池的生物量及压降。在实际应用中,应针对不同生物滤池选取最佳控制方法。

上海羿清环保生产的生物滤池臭气处理设备能够有效处理恶臭气体中的有害物质,而且不会产生二次污染,目前已经得到广泛应用。
