The ten-year development of chemical science and technology is praised, and China's prosperity and strength in the prosperous age are inspiring. Everyone's participation is more lively and the ocean is more exciting with you. Everyone is welcome to participate in more forum exchanges and discussions. Everyone pays attention to safety and knows how to respond to emergencies. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * The Mine Water and Coal Chemical Wastewater Treatment and Utilization Project of Ningdong Mining Area of Energy Ningmei Group Company started flushing the nanofiltration system in the second phase of the project at 17:00 on December 29, 2018. At 17:00 on December 30, 2018, the membrane group of the coal chemical series nanofiltration salt separation system began to debug the production of concentrated water, marking the full start of the trial run of the country's largest zero-discharge industrial wastewater project. * * Energy Ningmei Group Company's important environmental protection goal "12·30" milestone was achieved on schedule. It is reported that the mine water and coal chemical wastewater treatment and utilization project in the East Mining District is currently the largest industrial wastewater zero discharge project in China with the largest investment, the most complex process route, the highest product salt resource utilization, and the most advanced technology. The project covers a total area of 201,000 square meters, with a total investment of 1.69 billion yuan. The treatment scale is 3,000m3/h, the wastewater discharge volume is 24 million tons/year, the recycled product water is 23.76 million tons/year, the by-product first-class sodium chloride is 37,100 tons/year, and the anhydrous sodium sulfate is 39,300 tons/year. The project started on June 30, 2016 and is divided into two phases. ； Thanks to the continuous hard work of the coal-to-liquids chemical engineering construction headquarters and more than 1,000 construction personnel from various construction units, the first phase of the project produced qualified recycled water on May 30, 2018, and the second phase of the project was commissioned with water input on December 30.

Which process technology is used in this zero industrial wastewater discharge project? The processing scale of 3000m3/h is quite large.
.Ningdong Project Introduction The Ningdong Mining Area mine water and coal chemical wastewater treatment and utilization project is a local* * An environmental protection project that is of concern to the environmental protection department. This project has long process lines, complex processes, large civil engineering volume, short construction period, many types of equipment and pipeline materials, and high installation requirements. The EP contractor of this environmental protection project is China Wuhuan Engineering Co., Ltd., and the project owner is Shenhua Ningmei Co., Ltd. The Ningdong project started construction in October 2016 and was put into production in February 2019. The production equipment of the mine water and coal chemical wastewater treatment and utilization project in Ningdong Mining Area covers an area of 20.1 hectares. The total processing scale is 3000m3/h. in: The mine water treatment capacity is 1500 m3/h, and the coal chemical wastewater treatment capacity is 1500 m3/h. 24.09 million tons of product water are recycled per year, and the treated product water reaches the quality standard of primary recycled water.
