A Discussion about Comprehensive Environmental Treatment and Protection in Pijiang River Catchment

The current situation, main problems and their causes of the environment of Pijiang River Catchment are discussed and analyzed. Abiding by the principle of ＂Combining Protection, Treatment and Development＂, we pro- pose to establish a comprehensive pollution control system, the alternative water sources for the polluted area, and to treat the contaminated land and improve the monitoring and supervision system. A number of engineerings are also suggested such as putting up facilities for industrial pollution treatment, the ecological restoration in the mining area, control of the urban pollution sources, river dredging , rehabilitation of the contaminated source water protection and so on. It is aimed to safeguard the water environmental safety and maintain the ecological balance in the catch- ment; as well as facilitate the communication between the upper and lower reaches and harmonious economic and en- vironmental development through the comprehensive ecological, engineering and management measures.
