| 摘 要： | 评价了生物强化活性炭(BAC)的生物降解与吸附作用协同对消毒副产物前体物质(DBPFP)的控制效果.控制 BAC 的空床接触时间(EBCT)为 20min 时,BAC 对卤乙酸生成势(HAAFP)的去除率达到 59%,而相同条件下,普通颗粒炭(GAC)对其去除率只有 27%.BAC 工艺中微生物数量和微生物活性均明显高于 GAC 工艺.通过微生物降解作用和活性炭吸附作用的协同,BAC 对 HAAFP 的去除率与 EBCT 具有明显的线性相关性(R2=0.9069).BAC 出水中指标 UV254与 HAAFP 也表现出一定的线性相关性(R2=0.7702).

| Abstract: | The control effect of DBPFP by cooperative of haloacetic acids formation potential biodegradation and adsorption was evaluated. As the empty bed contact time (EBCT) of BAC control was 20min, the removal rate of haloacetic acid formation potential (HAAFP) reached 59%. Under the same conditions, the removals of GAC was 27% only. For BAC technique the biology number and bioactivity were higher markedly than those of GAC. A marked linear correlation (R2=0.9069) existed between HAAFP removal rate and EBCT of BAC. In the effluent water of BAC, the indices HAAFP and UV254 also expressed definite linear correlation (R2=0.7702). |
