摘要：

再生水厂利用城市污水处理厂二级出水作为再生水的水源，采用二级曝气生物滤池+纤维球过滤工艺对污水处理厂二级出水进行处理，处理后出水作为再生水进行回用。由于来水水质的制约，严重影响了再生水厂的中水再生能力，通过改变再生水厂来水水源，将二级曝气生物滤池串联运行改为并联运行，提高了再生水厂的处理能力，降低再生水成本。

Abstract:

A water regenerating plant has used the secondary effluent water from the municipal sewage treatment plant as water sources. The secondary effluent water from the sewage treatment plant has been treated by using secondary aerated biological filter (BAF) -fabric globe filter technology. Then, the treated effluent water can be reused as regenerated water for being reused. Because of the restriction of the influent water quality, the water regenerating capacity of the water regenerating plant is affected seriously. Through changing the influent water sources of the water regenerating plant, the series connection running of the secondary BAF has been changed to parallel connection running. This improves the treatment capacity of the water regenerating plant and lowers the cost of the regenerated water.

Key words: secondary effluent water, biological aerated filter(BAF), regenerated water
