摘　　要：为了解决用户投诉的黄水、黑水现象,水厂从自身实际出发,研究水厂锰含量的时空分布发现,水厂工艺平流沉淀池锰富集严重。经检测,沉淀池中的锰主要集中在中部和尾部,尾部总锰是沉淀池头部总锰含量的六倍多;水厂在沉淀池清洗期间发现,清洗后的2~3个月是沉淀池锰富集的主要时期;锰达到一种平衡状态一般锰元素的富集周期在2个月左右,由此提出每两个月定期清洗沉淀池,并在每年的台风来临,水质恢复到正常后,再次清洗沉淀池。In order to solve the problem of yellow water and black water complained by users,the distribution of manganese content in water plant was studied from its own reality.It was found that manganese concentration in horizontal flow sedimentation tank of water plant was serious.After testing,the manganese in the sedimentation tank was mainly concentrated in the middle and the tail,and the total manganese in the tail was more than six times of the total manganese in the head of the sedimentation tank.It was found that 2~3 months after cleaning was the main period of manganese enrichment in sedimentation tank.The enrichment period of manganese was about 2 months,so it was suggested to clean the sedimentation tank regularly every two months,and clean the sedimentation tank again after the annual typhoon come and the water quality returns to normal.
