摘要
采用浊度,pH 和粪大肠杆菌数三个指标,对流经广州地区的珠江河段,市内各小河涌、井水,自来水等水源的污染情况的调查结果表明,珠江河段,各小河及地下水都受到不同段度的污染,作为饮用水的水源,珠江水的大肠杆菌数已大大超过国家规定的饮用水水源的标准.
Systemic survey was carried on for the faecal pollution of different water sources including Pearl River sec- tion,streams,wells,and tape water in Guangzhou using the turbidity,pH and faecal E.coli as parameters.The results show that waters from Pearl River,streams and underground were polluted in some ex- tent.As the source for drinking water,the number of faecal E.coli was much higher than the state standard of the source of drinking water,which should be pay more attention by depart- ments concerned.
