introduction to China coal processing and Utilization Association

China coal processing and utilization association was established in 1982. It is a national industry association managed by the state owned Assets Administration Commission of the State Council and registered by the Ministry of civil affairs

business scope: coal washing and processing, coal deep processing and coal chemical industry, coal mine energy conservation, mining area environmental protection, comprehensive utilization of coal waste resources (coal mine water, coal mine gas, gangue slime low calorific value fuel power generation, oil shale and other associated resources, waste building materials)

the association provides two-way services to the government and enterprises, and gives full play to the functions of government think tanks, industry management and consulting platforms through investigation and research, information consulting, technical services, exchanges and cooperation, etc; Publicize national policies, promote industry self-discipline, reflect the demands of enterprises, safeguard the legitimate rights and interests of members, etc

since its establishment, with the strong support of relevant superior departments and member units, the association has done a lot of work around coal washing and processing, industrial structure adjustment and product structure optimization, clean and efficient transformation of coal, energy conservation and emission reduction, clean production and circular economy, comprehensive utilization of resources, and achieved obvious economic and social benefits, in order to promote the rational development and utilization of coal resources, It has made important contributions to promoting the healthy and sustainable development of the coal industry

as a link between the past and the future, the association will continue to keep pace with the times, implement China's coal green development and clean and efficient utilization strategy, help the transformation and upgrading of the coal industry, give full play to the association's role as a bridge and link between the government and enterprises, promote clean production of coal products, ecological civilization construction, transformation of coal from fuel to both fuel and raw materials, comprehensive utilization of waste resources, etc., and promote the green development, circular development Low carbon development, and make active efforts to create a new situation in China's coal processing and utilization

brief introduction of the visit project

Ningdong mining area mine water and coal chemical wastewater treatment and utilization project

the visit project is located in Ningdong coal chemical industry base of Ningdong energy chemical industry in Ningxia Autonomous Region. The project is under the general contract of EP (design and procurement) of China Wuhuan Engineering Co., Ltd. and the construction party is Ningdong coal infrastructure company. The total investment of the project is 1.6 billion, and the production plant covers an area of 20.1 hectares

the construction scale of the project is 3000m/h, of which the mine water treatment capacity is 1500m/h, and the wastewater treatment capacity of the coal chemical industry park is 1500m/h. The mine water and the wastewater of the coal chemical industry park are completely treated separately. After the treated product water reaches the primary reclaimed water quality standard (TDS ＜ 500mg/l), it is reused in the chemical industry projects in the park as the make-up water for circulating cooling water. The concentrated brine produced by the project is sent to the evaporation crystallization unit for treatment after membrane concentration and salt separation. The annual by-products of the project are 37100 tons of sodium chloride crystal salt and 39300 tons of anhydrous sodium sulfate, which meet the standards of gb/t refined industrial dry salt and gb/t anhydrous sodium sulfate class II first-class product respectively, and the recovery rate of product salt is more than 85%
