| 摘 要： | 《城镇污水处理厂污染物排放标准》(GB18918-2002)规定了总磷的排放标准:当污水排放达到一级A标准时,在2005年12月31日前建设的污水厂为1 mg/L,2006年1月1日起建设的污水厂为0.5 mg/L。现在化学除磷辅助生物除磷成了所有新建污水厂除磷工艺的选择,本文在介绍生物和化学除磷机理的基础上,对生物除磷和化学除磷的控制要素作了相关的分析和论述。

| Abstract: | The discharge standard of pollutants for municipal wastewater treatment plant(GB18918-2002) prescribed standards for the total phosphorus.The primary A standard prescribed that TP of treated wastewater shall not exceed 1 mg/L in the wastewater treatment plants built before Dec 31st,2005,and TP shall not exceed 0.5 mg/L in plant built since January 1st,2006.Supplemental chemical phosphorus removal for biological phosphorus removal process becomes the choice of all new wastewater treatment plants.This paper introduced the mechanism of chemical phosphorus removal and biological phosphorus removal,and made interrelated analysis and discussed for control factors of phosphorus removal. |
