Background technique

Water treatment refers to the purification of polluted industrial wastewater or river water through a series of water treatment equipment to meet the water quality standards stipulated by the state. Water treatment, including water supply treatment, sewage and rainwater treatment, etc. refers to the process of changing the composition of water through man-made or natural phenomena. Artificial water treatment can be divided into treating natural water for human use, and treating waste water after human use and then discharging it into nature.
