Overview
Heilongjiang wastewater treatment plant serves Hulin City in Heilongjiang Province, China, with a population of 81,000. It operates under Chinese national wastewater standards.
The Heilongjiang wastewater treatment plant is located in Hulin City, Jixi, Heilongjiang Province, China. It serves a population of approximately 81,000, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. As a plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants serving populations over 50,000, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant's treated effluent likely discharges into a local watercourse that eventually flows into the Ussuri River or the Songhua River basin, both part of the larger Amur River system. This region supports diverse aquatic ecosystems and is important for migratory fish species. Proper treatment helps protect downstream water quality in this ecologically significant area.
Environmental context
The plant is located in the Amur River basin, with effluent likely draining into the Ussuri River or a tributary, eventually reaching the Sea of Okhotsk. The region supports diverse aquatic life, including salmonids and other migratory fish, and is ecologically sensitive due to seasonal flooding and agricultural runoff. Effective wastewater treatment is crucial to prevent eutrophication and protect downstream habitats.
