Making the River Steady, Protecting Water Quality and Improving Ecology: Eco-treatment Practice of Liaohe Conservation Area

Since the Liao River basin eliminated water quality worse than class V for COD in the mainstream in 2009, the water pollution control has acquired breakthrough progress. Currently, in accordance with the five main indicators of surface water (COD, NH₃-N, BOD₅, DO, pH) detection, the water quality has reached class IV and been relatively stable, the fish has been restored to 40 kinds, and the river marked fish, saury, has been reproduced. Liaoning Provincial Government designated the mainstream of Liaohe as conservation area and established a conservation bureau. This is the first administration to be set up in China carrying out integrated basin management. This has provided institutional guarantees for implementation of multi-objective integration to protect the mother river of Liaoning people. The eco-treatment technology and practice of Liaohe Conservation Area were introduced. It has great significance on implementing the state strategy of “construction of ecological civilization”, accomplishing coordinated growth between economy and environment, and realizing harmony between people and nature.
