China Drying Network News On July 31, the 2012 China Petroleum and Chemical Industry Wastewater Utilization Technology New Technology Application Symposium hosted by China Chemical Industry News was held in Beijing. At the meeting, experts from the Environmental and Economic Policy Research Center of the Ministry of Environmental Protection analyzed the opportunities for the recycling of chemical wastewater; experts from the Water Treatment Center of the Sinopec Research Institute of Petroleum and Petrochemicals introduced the progress of wastewater treatment and reuse technology; experts from Beijing University of Chemical Technology described Energy-efficient high-concentration ammonia nitrogen wastewater treatment complete sets of technology; Harbin Institute of Technology experts analyzed the key issues of coal chemical wastewater zero-emission technology. In the face of the current upsurge of investment in coal chemical industry, Mr. Xu Xudong, chief engineer of Donghua Environmental Engineering Technology Co., Ltd. reminded the industry that the new coal chemical industry consumes a huge amount of water. The tons of large-scale projects consume more than 10 tons of water and the annual water consumption is usually as high as several thousand. Million cubic meters. China's coal resources are mainly concentrated in the north and northwest, where these areas are seriously inadequate water resources. The rapid development of coal chemical industry has caused imbalances in the supply and demand of regional water resources. At present, disputes over water rights have emerged in these areas. To this end, Si Xudong suggested that governments and enterprises should pay attention to protecting the ecological environment and avoid water and groundwater pollution in investing in coal chemical projects. At the same time, the coal chemical project itself needs to achieve zero discharge of sewage and maximize the reuse of sewage to alleviate the severe shortage of water resources. Treatment of coal chemical wastewater requires different wastewater treatment technologies for different processes. In addition, a large amount of circulating water is needed in the production process of coal chemical industry. In order to save water resources, it is necessary to consider reuse of water.
