摘要
Abstract
Effluent chromaticity is an important factor in sewage treatment industry.The cause of intermittent yellowing of effluent from a sewage treatment plant in Chongqing is investigated and analyzed.According to the investigation,it is found that the possible causes of effluent yello-wing are sludge disintegration,high concentration of ammonia nitrogen and the presence of non-ferrous metal ions.According to our experi-mental analysis,the main reason is the existence of manganese ion,and the current sewage treatment technology cannot effectively remove man-ganese ion.Based on this,this work reports using sodium bicarbonate as coagulant in the primary sedimentation tank can effectively reduce the concentration of manganese ion and thus effectively reduce the effluent chromaticity.关键词
