摘要：

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。

Abstract:

The technique of removing residual aluminum by flocculation clarificatio n process was intro duced in t his paper. The exper iment results showed that the residual aluminum concentr ation could be less than 0. 2 mg/ L after it was treated under the conditions of right flocculant, reasonable stirr ing streng th and long enoug hreactio n time.
