Jiangsu Wastewater Treatment Plant, Hongze District, Huai'an, Jiangsu, China

The Jiangsu wastewater treatment plant is situated in Hongze District, Huai'an, within Jiangsu Province, China. It serves a population equivalent of 137,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a facility in China, the plant operates under the national Water Pollution Prevention and Control Law, which sets discharge standards for municipal wastewater. For agglomerations of this size, secondary treatment is typically required, with potential nutrient removal in sensitive areas. The plant's capacity suggests it handles a significant volume of wastewater from the urban and industrial areas of Hongze District. The plant's discharge ultimately reaches the Hongze Lake, one of China's largest freshwater lakes, which is part of the Huai River basin. Hongze Lake supports diverse aquatic life and provides water for irrigation and drinking. The lake drains into the Huai River, which flows to the Yellow Sea. Protecting this water body is critical for regional ecology and water security.

The plant's treated effluent likely discharges into Hongze Lake, a major freshwater lake in the Huai River basin. Hongze Lake is ecologically significant, supporting fisheries and migratory birds. The lake connects to the Huai River, which flows eastward to the Yellow Sea. Nutrient loading from wastewater can impact lake water quality, making effective treatment essential for maintaining aquatic health and downstream ecosystems.
