Abstract

The results showed that the reclaimed water was mainly used for industrial purposes, municipal use, replenishment water of ecology and environment, and irrigation water in the central urban area. The reclaimed water demand for ecological and environmental use is the largest, accounting for 69.9% of the total demand. The water quality of the wastewater treatment plants can meet the Grade A standard of discharge standard of pollutants for municipal wastewater treatment plants.
