2008年5.12汶川大地震后,绵阳涪江出现高浊度源水的频率以及持续时间都逐年增长,严重影响了该流域自来水厂的供水安全。本文对汛期涪江高浊度源水进行了水处理工艺试验研究,揭示了混凝剂PAC投加量、水体pH值与锰离子含量三者之间的相互影响关系,还总结了采用高锰酸钾氧化法去除锰离子与多级混凝处理工艺中各药剂的投加量,希望能对同行朋友在处理类似问题时有一定的帮助。
After the 5.12 Wenchuan earthquake in 2008, the frequent occurrence and duration of high-turbidity source water in Fujiang, Mianyang City increased year by year, seriously affecting the water supply safety of the waterworks in this basin. In this paper, high-turbidity source of Fujiang River flood season water treatment process experimental study revealed the coagulant PAC dosage, pH value of water and manganese ion content of the interaction between the three, but also summed up the use of high-manganese Potassium and potassium oxide removal of manganese ions and multi-stage coagulation treatment of the dosage of various drugs, hoping to peer friends in dealing with similar problems have a certain amount of help.
