Abstract

The "Major Science and Technology Program for Water Pollution Control and Treatment" is one of 16 major projects of the national medium and longterm science and technology development plan. The Liaohe River basin is one of key basins for state water pollution control. Based on the summary and analysis of water environmental problems, this paper introduces two technology systems including thought, target, framework, and content forwatershed water pollution control and treatment and management in Liaohe River basin. During the "11th Five-year" plan, some research and demonstration projects have been carried out successfully covering aquatic ecological function zoning, water quality benchmarking technology, aquatic ecological carrying capacity, water quality management in the control unit, water pollution control in key industries, and early warning and risk management of water environment. The two technology systems have played a positive significant role in the water quality improvement and ecological restoration of Liaohe River basin. A new water environmental management mode—"zoning, classification, grading, staging" mode— has been established in the whole basin, which will promote the spread of the watershed water quality target management.
