Abstract:

为强化曝气生物滤池(BAF)的除磷效果,以石化二级出水为处理对象,研究了投加FeSO4·7H2O对BAF除磷性能的强化作用并对投量进行了优化,同时分析了FeSO4·7H2O投加对BAF除碳、脱氮和生物膜活性的影响。结果表明:投加少量FeSO4·7H2O(3~15mg·L-1)能有效强化BAF的除磷性能;BAF除磷的效果随FeSO4·7H2O投加量的增加而提高,但在投量高于9mg·L-1时增加趋势逐渐变缓,当FeSO4·7H2O的投加量为9mg·L-1时,TP的去除率达到57.0%以上,而同期平行运行的BAF除磷效率为7.1%。BAF中少量投加FeSO4·7H2O对COD的去除没有不良影响,COD的去除率比对比装置平均提高了5.4%左右,对相对分子质量较大的有机物去除明显。FeSO4·7H2O投加量低于12mg·L-1时对的去除没有不良影响,高于15mg·L-1时由于生物膜中微生物活性的下降去除率有所降低。投加FeSO4·7H2O对TN的去除影响甚微。Fe2+的投加使得BAF中附着微生物的量有所降低,但在12mg·L-1以下时不会造成大的影响,FeSO4·7H2O投量在3~9mg·L-1时BAF中生物膜的脱氢酶活性和比好氧呼吸速率有所增加,可弥补生物量降低的影响,因此BAF的运行状况未受到影响。
