On Cause Analysis and Treatment Strategy of River Water Pollution in Northern China

Taking the Weihe River in Baoji area as an example, the paper discusses the contaminants’ (counted with COD) production, treatment capacity, pollutant amount into the river, river water quality and relationship between annual water inflow distribution and river water quality in river channel. It is argued that it is impossible by relying solely on the sewage treatment to control the pollutant amount into the river and solve the river water pollution. The paper also presents that sewage reclamation is a new method to treat the river water pollution in Northern China.
