摘要
Abstract
After heavy metal poisoning of activated sludge, the metabolic activity of activated sludge will decrease rapidly, the pollutants removal performance of sewage treatment plant will reduce significantly, and the system will collapse in severe cases. During an sludge heavy metal poisoning incident occurred in a sewage treatment plant at a central city, the characteristics of sludge poisoning were analyzed in detail, and comprehensive countermeasures including the increase of aeration rate, influent control, regulation of sludge recycle flow and excess sludge discharge, and the addition of external carbon source were taken. Metabolic activity of sludge were quickly restored, and sewage plant returned to normal operation. This article analyzed and summarized the characteristics of activated sludge heavy metal poisoning in incident and process control measures adopted by sewage treatment plant, which can provide an effective reference for other sewage treatment plants to cope with similar incidents and achieve stable operation.关键词
