Overview
Shandong wastewater treatment plant serves Shouguang City in Shandong Province, China, with a population equivalent of 109,300 and a designed capacity of 1.00 unit.
The Shandong wastewater treatment plant is located in Shouguang City, part of Weifang Prefecture in Shandong Province, China. It serves a population equivalent of approximately 109,300, placing it in the medium-to-large agglomeration category under Chinese wastewater regulations. The plant's designed capacity is 1. As a facility serving over 100,000 people, it is subject to China's national wastewater discharge standards, which require secondary treatment as a minimum. For plants of this scale, advanced treatment may be mandated if the receiving water body is classified as sensitive, such as for eutrophication control or drinking water source protection. The plant discharges into the local water system within the Shandong Peninsula region, which ultimately drains into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea that supports fisheries and maritime activities, making proper wastewater treatment critical to prevent nutrient loading and algal blooms. The plant's location inland, more than 50 km from the coast, reduces direct marine impact but still influences downstream coastal water quality.
Environmental context
The plant's treated effluent likely enters a tributary of the Xiaoqing River or a similar watercourse that flows into Laizhou Bay, part of the Bohai Sea. The Bohai Sea is a semi-enclosed water body with limited water exchange, making it susceptible to eutrophication from nutrient inputs. The region supports important fisheries and aquaculture, and excessive nitrogen and phosphorus from wastewater can lead to harmful algal blooms and oxygen depletion. Proper treatment is essential to protect the ecological health of the downstream estuary and coastal zone.
Frequently asked questions
The plant is located on Xingye Road in Shouguang City, Weifang Prefecture, Shandong Province, China.
The plant serves a population equivalent of 109,300, classifying it as a medium-to-large agglomeration under Chinese wastewater regulations.
The plant discharges into local waterways that ultimately flow into Laizhou Bay and the Bohai Sea. The region's drainage network feeds into the Bohai Sea.
The plant operates under China's national wastewater discharge standards, which require secondary treatment as a minimum. For plants serving over 100,000 people, advanced treatment may be required if the receiving water body is designated as sensitive.
In China, plants of this scale typically employ secondary biological treatment processes such as activated sludge or sequencing batch reactors. Advanced treatment (tertiary) may be added for nutrient removal if the effluent enters a sensitive water body.
