珠江澳门河口高浊度水的成因及其控制途径初探

STUDY ON THE CAUSE OF FORMATING HIGH TURBIDITY WATER IN Macao ESTUARY OF PEARL RIVER AND ITS SOLVING WAY

本文研究了珠江澳门河口的水质特征，研究结果表明水的浊度较高和有机污染较严重，而高浊度是有机污染的重要表现形式．高浊度成因主要是地理位置和人类活动的影响；当水中ｐＨ值大于７．５时，随着ＣＯＤ值的升高，悬浮颗粒的ζ电位增大，导致颗粒物的稳定性增大。

This paper studies the quality of water in Macao estuary. The results show that the turbidity was high, and organic pollution were serious. High turbidity was the importent form of expression to organic pollution. The cause of high turbidity are the geographical situation and the human activities.When pH value of water larger than 7.5,with the COD value of water increasing,the Zeta value of suspended solids is also increasing.This results in increasing the stability of suspended solids, then the turbidity of water is raising with it.
