摘要
以海水为试验对象,研究了不同实验条件下的强化混凝效应.试验结果表明,三氯化铁在去除浊度和CODMn上较其它混凝剂更有效;加大三氯化铁的投加量,海水的浊度和CODMn的去除率均呈现上升趋势,当投加量大于15 mg/L时,两者去除率的增长速度减缓;在维持海水pH值相对较低的条件下,辅以强氧化性助凝剂和适当的水力条件对海水混凝具有强化效应.
The effects of enhanced coagulation under different experimental conditions are studied, taking seawater as the target of experiment. The experimental results show that ferric chloride performs better in removing CODM, and turbidity than other coagulants. Increasing the dose of ferric chloride, the performance become better, but the trend become faint when the dose is larger than 15mg/L. Furthermore, at lower pH condition, reasonable hydraulic condition and injection of strong oxidant as coagulant aid would improve the seawater coagulation process.
