摘　　要： 采用胶体界面化学研究手段，着重研究水体悬浮细颗粒泥沙ξ电位和ｐＨ值、盐度、污水排放等影响因素的关系。微量有机物的加入可以改变细颗粒泥沙的ξ电位，水体ＣＯＤＭ ｎ大于５ｍ ｇ／ｌ时。 The effects of pH value,salinity,waste water discharge toward the stability of fine silt of Macao estuary of Pearl river were studied in this paper.The relationship between ξ potential of fine silt and pH value,salinity,waste water discharge was researched deeply.The research results showed that ξ potential of fine silt can be changed by tiny amount of organic materials,and fine silt was stabilized when the COD Mn of water is over 5mg/l.
