| 摘 要： | 研究了用于修复模拟受ＰＣＰ污染地表水的厌氧颗粒污泥反应器降解ＰＣＰ活性的维持条件和修复性能．结果表明，降解ＰＣＰ活性可通过连续提供电子供体和选择压力来维持，操作条件为ＣＯＤ进水／ＰＣＰ进水＞３０，此时反应器具有稳定的ＰＣＰ去除和产甲烷性能；颗粒污泥反应器修复受ＰＣＰ污染地表水的性能与过程稳定性受电子供体类型、数量的影响．当ＣＯＤ／ＰＣＰ＞１５０—２００，ＨＲＴ为０５ｄ时，含ＰＣＰ１２９１ｍｇ／Ｌ的模拟受污地表水经厌氧反应器修复后，其ＰＣＰ浓度可低于１ＰＰｂ，生物毒性明显降低．

| Abstract: | The operative conditions for maintaining PCP degrading activity of anaerobic ranular sludge reactor and its performance for remediating PCP contaminated surface water were investigated.The results showed that the PCP degrading activity could be maintained by supplying electron donor (organic wastewater) and selective pressure (PCP).The ratio of COD inf /PCP inf should be above 30 for stabilizing PCP removal and methanogensis in anaerobic reactor.The performances and process stability of anaerobic granular sludge reactor for remediating simulated PCP contaminated surface water were influence by the kinds and mass of electron donor.When the PCP contaminated surface water used as influent with PCP concentration of 12.91mg/L,1ppb of PCP in remediated water was obtained under COD inf /PCP inf >150 200 and HRT 0.5d,the biotoxicity of remediated water was disappeared. |
