采用混凝技术处理稀土冶炼废水

The Technology of Coagulation and Flocculation in Rare－earth Smelting Sewage Treatment

混凝剂的恰当选取是废水混凝处理技术的关键．利用多种混凝剂按不同比例配制成的综合混凝剂来处理某厂稀土冶炼废水，试验结果表明，此适当比例配制的综合混凝剂能有效地处理稀土冶炼废水，使其出水达标排放．

The key technology of coagulation and flocculation in waste water treatment is suitable selection from coagulant and flocculants． A lot of coagulant and flocculants which are disposed with a definite proportion ratewere choosen to treat rare－earth smelt waste water． The test results show that the complex the coagulant and flocculants could efficiently treat rare－earth smelt waste water and let the water quality of effluent meet to the national waste water discharge standard．
