Overview
Shandong wastewater treatment plant serves Luozhuang District, Linyi, China, with a population equivalent of 200,000. It discharges into the Yi River, part of the Huai River basin.
The Shandong wastewater treatment plant is located in Luozhuang District, Linyi, Shandong Province, China. It serves a population equivalent of 200,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated near the Yi River, a major tributary of the Huai River system. As a facility serving over 100,000 people, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients. Typical plants of this scale employ activated sludge processes with nutrient removal. The treated effluent is discharged into the Yi River, which flows into the Huai River and eventually reaches the Yellow Sea. The plant plays a critical role in protecting the Yi River water quality, which supports local agriculture, fisheries, and downstream ecosystems. The region experiences a temperate monsoon climate, with seasonal variations in flow and pollutant loads.
Environmental context
The plant discharges into the Yi River, a tributary of the Huai River, which flows eastward to the Yellow Sea. The Yi River supports diverse aquatic life and is used for irrigation and drinking water supply downstream. The Huai River basin is ecologically sensitive, with issues of eutrophication and industrial pollution. The plant's treatment performance directly affects the health of this watershed.
