摘要
针对6×10~4m^3/d临安城市污水厂尾水的水质特点,采用基于水资源循环利用的多级复合式高效植物生态系统工艺对其进行深度处理。结果表明,经过两年多的运行,出水水质达到了设计标准,除TN外,其他指标均达到《地表水环境质量标准》(GB 3838—2002)的Ⅳ类标准,有效改善了东笤溪带的水环境质量,并实现了一定的社会经济效益。
Based on the effluent quality of Lin＇ an municipal wastewater treatment plant, the pro- ject of a multi-stage composite effective plant ecosystem with treatment capacity of 6 × 10-4 m3/d was de- signed to recycle and reuse the effluent. The results showed that the effluent quality could meet the design requirement after more than two years operation. All the items except TN reached the Environmental Quality Standards for Surface Water （ GB 3838 - 2002） class IV standards. The plant ecosystem effluent effectively improve the water environment of East Sea River belt, and in turn, which achieved a certain social and economic benefits.
