Description
This dataset represents the average level of advanced treatment at tap water treatment plants in Henan, covering the full production process of tap water from raw water intake to plant effluent, specifically including conventional treatment units such as water intake, coagulation-sedimentation, filtration, disinfection, water storage and water conveyance, while also covering advanced treatment stages such as activated carbon adsorption, ozonation and membrane filtration. The dataset focuses on recording the use of chemicals such as coagulants, disinfectants and sludge treatment agents, as well as electricity consumption, plant construction and maintenance, and related aspects. The data are sourced from statistical yearbooks.
Activity Description
The water production process of water plants mainly purifies raw water through a series of treatment units (such as coagulation, sedimentation, filtration and disinfection). During operation, the system mainly consumes electricity and uses a variety of agents such as coagulants and disinfectants to remove suspended solids, pollutants and pathogenic microorganisms in the water. Some water plants also introduce advanced processes such as activated carbon adsorption, ozone oxidation or membrane treatment to further improve the quality of effluent water. The entire treatment process has stable water output and reliable water quality. Its environmental impact is mainly reflected in two aspects: energy consumption and chemical use.
Process Description
Tap water refers to water supply that meets national health standards after purification, disinfection and other processes of source water (such as rivers, lakes, groundwater, etc.) through tap water treatment plants. It can be directly used for domestic drinking and daily production activities.
