磷矿浮选废水治理的探索与实践

Study on the Waste Water Treatment of Phosphate Ore Flotation and its Practice

酸碱中和破坏尾矿废水胶体分散系，使细悬浮微粒形成絮状沉淀物沉降在库区内，浑浊的尾矿废水变澄清。处理后的外排清水ｐＨ 值控制在７ ～８ 时。

After the colloid dispersion system being destroyed by neutralization reaction of acid and alkli,the flocculating sediments formed by fine suspension particle were settled in the tailing pond,so that muddy tailings waste water was changed into clear water.when the pH value of clear water discharged after treatment was controlled in the range of 7～8,other indexes reached the second grade of discharge standard of the State.
