摘要
研究能耗、物耗和二次污染最少化的城镇污水处理绿色工艺已成为我国城镇污水处理技术研究的重要方向。国内新研究开发成功的厌氧水解—高负荷生物滤池和蚯蚓生态滤池就是其中突出的代表。通过处理工艺、环境影响和技术经济指标诸方面的比较 ,可以看出 ,厌氧水解—高负荷生物滤池和蚯蚓生态滤池这两种绿色技术的污水处理效果达到或超过了活性污泥法 ,既大幅度减少了剩余污泥产量和其他二次污染物 ,又可节约 2 0 %～ 45 %的工程造价 ,5 0 %～ 65 %的运行费用 ,操作管理简单方便 。
The best practical environmental option for municipal wastewater treatment provides the most benefit to the environment as a whole, at lower investment cost, lower material energy consumption with less maintenance need and less environmental releases. The sewage treatments with the combination of an anaerobic fixed\|film reactor followed by a high\|rate trickling\|filter without re\|circulation and with the earthworm bio\|filter were investigated. The new processes have got good results of pollutant removal, and will save 20%～45% of the investment cost and 50%～65% of the operation and maintenance cost, have lower sludge production and an easier maintenance than the traditional activated sludge process.
