排水渠污水自然净化研究

On the natural purification of the water in offtake

通过对位于某市城郊结合部的泄洪排水渠渠水进行水质分析,提出了氧化塘和人工湿地法自然净化方案,具体为:前期处理工艺—氧化塘处理—人工湿地处理,即先对污水进行分流收集,使水中混浊物沉淀,再采用人工湿地污水处理系统—垂直流人工湿地,使污水发生质的变化,达到景观用水的要求,从而在减少污染的同时美化环境.

The researchers perform an analysis of discharged offtake water in the rural and municipal borders,and offer a natural purification program consisting of oxidation pond and wetland method. The scheme includes pretreatment technology,oxidation pond and artificial wetland treatment. The split-flowing and collection of water precipitates the muddy materials. Vertical flowing wetland results in the clean water for landscape use. This program is, therefore, thought as both reducing the water pollution and beautification of the environment.
