摘要
焦化废水是含有大量难降解有机污染物的工业废水,其成分复杂,采用传统的A-A/O活性污泥工艺处理蒸氨后的高浓度焦化废水。结果表明,该工艺可使COD、氨氮去除率分别在96%、98%以上。
Coking wastewater contains a large number of refractory organic pollutants.To treat the wastewater containing high concentration ammonia by the traditional A-A/O activated sludge process.The results showed that the removal rates of COD and ammonia nitrogen were respectively higher than 96% and 98%.
