强化絮凝净化法脱除水中的残留铝

TECHNIQUE OF REMOVING RESIDUAL ALUMINUM BY FLOCCULATION CLARIFICATION

研究了在给水工业中使用铝盐净水过程中脱除水中残留铝技术，分析了水中残留铝的原因。理论分析及实验表明，采用适宜的絮凝剂、合理的搅拌条件和适当延长絮凝反应时间，能使处理后水的铝含量降至０２ｍｇ／Ｌ以下。

The technique of removing residual aluminum by flocculation clarification process was introduced in this paper. The experiment results showed that the residual aluminum concentration could be less than 0.2 mg/L after it was treated under the conditions of right flocculant, reasonable stirring strength and long enough reaction time.
