| 摘 要： | 简要介绍化粪池的原始功能、负面效应、建设费用、技术管理等方面内容;分析新形势下兴建集中式污水处理厂取代传统化粪池的可行性;探讨化粪池设置对进入污水处理厂中有机物负荷削减产生的对脱氮除磷不利影响;提出修正化粪池设置有关规范和取消化粪池后室内外管线布置等有关技术措施;明确有集中式污水处理厂的城市(城镇)可以完全取消化粪池的意义。

| Abstract: | The function,deficiency,construction costs and,management of septic tanks were briefly introduced.Feasibility for centralized wastewater treatment plants(WWTPs) replacing septic tanks was analyzed.The negative effects of septic tanks on nitrogen and phosphorus removal were discussed,which was caused by the decreasing of organic loadings into the WWTPs.Some suggestions about revising the location criterion of septic tanks and pipeline layout techniques after canceling septic tanks were made.Finally,the significance for replacement of septic tanks with centralized wastewater treatment plants(WWTPs) was concluded. |

| Keywords: | wastewater treatment septic tank domestic wastewater nitrogen and phosphorus removal |
