珠江三角洲城镇污水的水质特征

Quality of the Sewage in Pearl River Delta

从珠江三角洲城镇人群的排污特点、城镇下水道的结构特性及其环境条件等方面论述珠江三角洲城镇污水的水质特征．认为：水量大、污染物含量低、ＢＯＤ５／ＣＯＤＣｒ值小是珠江三角洲内城镇污水的共性．在实施“广东碧水工程”计划，到处兴建城镇污水处理厂的今天，应充分重视这一特性，并将它列为主要的进水水质指标加以控制，以达到保障处理效果、节省能耗之目的．

Characteristics of the sewage quality in Pearl River Delta were discussed from the points of view of pollutant raising, sewer structure and its environmental conditions Results show that pollutant content and the ratio of BOD 5/COD Cr of sewage in Pearl River Delta are low, which should be mentioned while constructing a sewage treatment plant
