Overview
Hainan wastewater treatment plant serves Jiyang District, Sanya, Hainan, China, with a designed capacity of 1.00 unit and serves a population of 80,000. It is located within 50 km of the coast.
The Hainan wastewater treatment plant is located in Jiyang District, Sanya, Hainan Province, China, near the Yalong Bay area. It serves a population of approximately 80,000 people, making it a medium-sized agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a facility in China, the plant operates under national wastewater discharge standards, which are enforced by local environmental protection bureaus. For agglomerations of this scale, secondary treatment is typically required, with potential for advanced treatment if the receiving water body is sensitive. The plant's proximity to the coast (within 50 km) suggests that treated effluent may eventually reach marine environments, necessitating compliance with stringent discharge limits to protect coastal water quality. The plant's treated wastewater likely discharges into local watercourses that flow into the South China Sea. The Yalong Bay area is a popular tourist destination, and the surrounding marine ecosystem supports coral reefs and diverse aquatic life. Proper treatment is essential to prevent nutrient pollution and protect the ecological health of the bay and downstream coastal waters.
Environmental context
The plant is situated in the Yalong Bay watershed, which drains into the South China Sea. The bay supports coral reefs and marine biodiversity, making it ecologically sensitive to nutrient loading and pollution. Treated effluent from the plant must meet national discharge standards to safeguard the coastal environment and recreational water quality in this tourism-dependent region.
