Recently, the Ministry of Industry and Information Technology and the Ministry of Water Resources jointly announced the "Catalog of Industrial Water-Saving Processes, Technologies and Equipment Encouraged by the State (2023)".
  The 2023 edition of the catalog is mainly divided into R & D, industrialization demonstration, and promotion and application categories according to the stage of process, technology and equipment. It covers common general technologies and water-saving processes, technologies and equipment such as wastewater recycling, efficient cooling or washing, substitution of high-water-consuming production processes, and synergy of water conservation, pollution reduction and carbon reduction in 13 industrial industries such as steel, petrochemical chemicals, textile dyeing and finishing., a total of 171 items.
  32 processes, technologies and equipment in the petrochemical and chemical industry entered the catalog, namely: Petrochemical water conservation and emission reduction complete integrated process, petrochemical sewage air flotation biochemical filtration regeneration and reuse complete technology, refining enterprise water balance testing and optimization analysis system, refining sewage advanced treatment and reuse technology, refining wastewater advanced treatment and electrodialysis desalination combined process, refining catalyst comprehensive wastewater treatment and reuse technology, condensed water active molecular membrane ultra-micro filtration combined multi-functional fiber adsorption technology, coal chemical wastewater treatment and reuse integrated technology, coal chemical wastewater treatment and reuse technology, coal chemical wastewater treatment and reuse technology, Complete technology for zero-emission and resource utilization of high-salt wastewater from coal chemical industry, complete technology for treating high-concentration wastewater from direct coal liquefaction, zero-emission technology for salt-containing wastewater from chlor-alkali chemical industry, solid alkali evaporation alkaline condensate treatment technology, ionic membrane chelating resin tower Regeneration wastewater reuse technology, full-membrane method three-wash water filtration and recovery technology, multi-stage adsorption and desalination, regeneration and reuse technology for titanium dioxide wastewater, titanium dioxide acid wastewater treatment and recycling equipment, full high-titanium slag titanium dioxide production water washing process technology, Process integration technology for making coal slurry from chemical wastewater, membrane integration technology for high-salinity chemical wastewater resource utilization, chemical wastewater double alkali chemical hardening technology, waste salt water recycling technology for hydrazine hydrate production, ethylene glycol condensate recycling technology, incremental gas production Water treatment and reuse technology, forced circulation heating reaction system for epichlorohydrin saponification tower, water-saving equipment for furfural production, molecular sieve treatment technology for petroleum exploitation sewage, electrocatalytic oxidation treatment technology for offshore platform domestic sewage, High temperature, high salinity and high hardness heavy oil produced water treatment and reuse technology, large diameter, pollution resistant, high-flux ceramic membrane oilfield reinjection water treatment technology, polymer flooding oily sewage treatment and reuse technology, and high temperature resistant integrated water treatment equipment.
