摘要

摘要: 针对现有焦化废水处理工艺中存在的对水中化学需氧量（COD）和含氮污染物处理效果不稳定、功能菌群活性差等问题，探讨了双级串联序批式反应器用于人工模拟焦化废水的处理效能及其相关污染物降解规律。结果表明，双级串联序批式反应器对COD、氨氮、挥发酚的去除率经一级处理后相对稳定在88.33%、89.29%、92.86%，二级处理后相对稳定在95.83%、96.43%、98.57%；对氮杂环有机物（NHCs，吡啶、喹啉、吲哚）中吡啶、喹啉、吲哚的一级去除率分别为48.3%、87.13%、100%，二级去除率分别为91.09%、91.82%、100%；对急性生物毒性削减98%以上。大部分污染物质在一级处理的好氧段被降解，后续阶段可对残余污染物进一步去除；经污染物梯度浓度变化定向驯化的微生物菌群对废水中主要污染物质有良好耐受性，相关功能菌群丰度较高，多为兼氧菌。研究表明双级串联序批式反应器可用于实现焦化废水的高效稳定处理。

Abstract: In response to the problems of unstable treatment effects on chemical oxygen demand （COD） and nitrogen-containing pollutants in water， and poor activity of functional bacterial communities in existing coking wastewater treatment processes， this paper explored the treatment efficiency and related pollutants’ degradation laws of a two-stage cascade sequencing batch reactor for coking wastewater treatment. The results showed that the removal rates of COD， ammonia nitrogen， and volatile phenols by the two-stage series sequencing batch reactor were relatively stable at 88.33%， 89.29%， and 92.86% after the first stage treatment， and at 95.83%， 96.43%， and 98.57% after the second stage treatment. The primary removal rates of COD， ammonia nitrogen， volatile phenols， and pyridine， quinoline， and indole in nitrogen heterocyclic organic compounds in coking wastewater were 48.3%， 87.13%， and 100%， respectively， and the secondary removal rates were 91.09%， 91.82%， and 100%， respectively； acute biological toxicity was reduced by more than 98%. Most pollutants were degraded in the aerobic stage of primary treatment， and residual pollutants can be further removed in subsequent stages. The microbial community that had been selectively domesticated through changes in pollutants’ gradient concentration showed a good tolerance to the main pollutants’ species in wastewater， and the abundance of related functional microbial communities was relatively high， mostly facultative bacteria. This research proued that a two-stage series sequencing batch reactor can achieve efficient and stable treatment of coking wastewater.
