What is the near zero emission of coal-fired power plants?

Near zero discharge of sewage treatment in coal-fired power plants refers to the activities of infinitely reducing pollutants and energy emissions until they reach zero. From the perspective of sewage treatment equipment and sewage treatment industry cycle, domestic urban reclaimed water, industrial wastewater treatment, industrial wastewater treatment and high-salt wastewater treatment will develop rapidly in the future.

The application of near-zero emission technology in coal-fired power plants has a long history. In fact, in 1973, the Florida power plant in the United States realized the first power plant wastewater zero discharge in the world. Subsequently, there were successful cases of zero wastewater discharge in metallurgy, papermaking, chemical industry, electroplating, food and other industries. As early as 1994, Japan also regarded recycling industry as the basis and direction of future industry. In order to promote the development of zero emissions more effectively, UNU established the "UNU Zero Emissions Forum" in 1999.

For the sustainable development of China's economy and society, "Xingrui" combined with more than ten years' experience in water treatment, and after hundreds of tests, worked out "the overall solution of sewage reuse in circulating water system with almost zero pollution discharge". The wastewater can be reused in the circulating water system after simple treatment. Under the premise of ensuring that the circulating water system equipment does not scale and corrode for a long time, no or less sewage is discharged, and the advantages of the circulating water system are used to promote the degradation and consumption of sewage. Not only reduces pollution emissions, but also saves a lot of water resources; It not only reduces the production cost, but also reduces the damage to the environment.

In addition, what is the environment of Xingrui (Shandong) in terms of dosing mode and dosing frequency? "Protruding metering pump" is used to continuously and evenly add it near the suction port of circulating water pump for 24 hours, which ensures the stability of drug content in circulating water to the greatest extent.
