摘要
提出了出水满足水质标准兼顾对目标污染物抗冲击负荷能力的活性炭失效诊断方法。中试结果表明,S 市 M 水厂运行9年后的1#炭对 CODMn和 DOC 的平均去除率分别为22%和31%；对苯酚、2 MIB 以及三氯乙醛前体物等目标污染物的去除能力分别为76.9%~93.1%、30.0%~44.1%及28.0%。相比2#新炭的运行效果而言,1#炭对有机物仍具有去除效果且出水能够满足水质标准,对目标污染物也具备一定的抗冲击负荷能力。
This paper brought forward the evaluation method for the inability of activated carbon to treat the water and to take the shock load of pollutants.The pilot study showed that the average removal rates of CODMn and DOC of 1 # activated carbon in M Water Treatment Plant of S City were 2 2 .0% and 3 1%,respectively;its removal rates on phenol,2-MIB and the precursor of chloral were 7 6 .9%~93.1%、30.0%~44.1% and 28.0%,respectively.Compared with the operation results of 2# new car-bon,the removal ability of 1# activated carbon on organic matter contend could meet the standards of effluent and 1 # activated carbon could also sustain the shock load to some degree.
