京津城市废水中洗涤剂——磷酸盐污染的评价

本文通过对北京高碑店污水场、天津纪庄子污水场及西苑饭店废水中阴离子表面活性剂的测定和调查,估算在废水总磷酸盐中洗涤剂磷酸盐所占份额,以评价其污染程度。测定的高碑店污水中阴离子表面活性剂含量平均为1.5 mg/l,洗涤剂磷酸盐约占污水中总磷酸盐的6.4～9.7％。调查的纪在子污水中活性剂含量为2.08mg/l,其洗涤剂磷酸盐占总磷酸盐的3.9～5.9％。 

Pollution Assessment of phosphate from Detergents in the Urban Waste Waters

The contents of anionic surfactants in the waste waters of the Beijing Gao Bei Dian and Tien Jin Ji Zhuang Zi waste water treatment plants, and of the Xi Yuan hotel were measured and investigated. On the basis of obtained data the portions of phosphate supplied by the detergent to the total phosphate in the urban waste water were estimated. The content of anionic surfactants in the Gao Bei Dian waste water is a mean of 1. 5mg/ 1, that in the Ji Zhuang Zi is 2.08mg/ 1. The phosphate from the detergent in Gao Bei Dian accountsyor 6.4-9.7% of the tatol phosphate content, that in Ji Zhuang Zi accountsyor 3.9-5.9%.
