Wastewater treatment In China
Water pollution is just one of the environmental challenges facing China’s policy makers. According to statistics , around 32.5% of China’s 7 major river systems and 29.2% of China’s major basins do not meet the prevailing water quality standards (grade III and below) in 2015. Municipal wastewater treatment is typically undertaken by local governments, especially in the urban areas. Industrial wastewater treatment, on the other hand, is often done in-factory or in centralized treatment facilities located within industrial parks. the graph shows the wastewater treatment volume, capacity and cost.
