How to achieve zero discharge of desulfurization wastewater? Let's take a look together. Usually, the discharge of desulfurization wastewater from power plants is still difficult to meet the standards after traditional treatment, and there is secondary pollution in the discharge of harmful substances in water, which cannot be implemented in areas with strict water environment protection. In addition, there are technical obstacles in the reuse of zero discharge of desulfurization wastewater from power plants, some of which are used for ash yard, coal yard spray, etc., and cannot be completely recovered. Traditional pre-treatment also contains high salt, high chloride ions, and trace heavy metals, which have significant limitations in repeated use. The characteristics of high salt and high chloride ions require reusable equipment to have high materials, which may have other uncertain adverse effects on system concentration. However, at the same time, the improvement of corporate environmental protection social responsibility and the promotion of policy regulations provide opportunities for zero discharge technology of desulfurization wastewater. According to the differences in emission standards, takeover, and zero discharge, the wastewater treatment process can be divided into the general treatment process of desulfurization wastewater and the zero discharge treatment process of desulfurization wastewater.
What is the significance of zero discharge of desulfurization wastewater? Let's take a look together.
The zero discharge treatment of desulfurization wastewater is of great significance for the operation and development of coal-fired power plants, and also has a significant impact on the ecological environment of the country. At present, only by rapidly improving the operating status of desulfurization wastewater treatment equipment and continuously optimizing it can we promote the good development of power plants and also contribute to the civilization of the national ecological environment.
1. Make tremendous contributions to our social environmental protection cause:
The society we live in now is threatened by various types of pollution. In order to reduce this threat, we are also continuously conducting research on "zero discharge" of wastewater. At present, the "zero discharge" technology for industrial wastewater has also made significant breakthroughs. Significantly reducing pollution in the industrial sector and making significant contributions to environmental protection. This zero discharge environmental contribution based on wastewater has made great progress in recent years
2. To a certain extent, it ensures the safety of domestic water in China:
The zero discharge system of desulfurization wastewater greatly reduces the probability of domestic water pollution, and in recent years, there have also been cases of water pollution endangering the health of residents. In order to prevent this situation from happening, it is urgent to use a zero discharge system for desulfurization wastewater. Ensuring the safety of our domestic water supply is also the responsibility of residents' life safety.
3. Significantly saving the use of water resources:
The use of zero discharge systems for desulfurization wastewater has greatly improved the utilization rate of water resources in China. The treatment of wastewater has greatly improved the recovery and utilization of water resources, reduced the use of fresh water, and alleviated water scarcity.
In recent years, many enterprises have responded to the national call for "energy conservation and emission reduction" by deeply treating all industrial wastewater. On the one hand, they can recycle the treated water, and on the other hand, reduce environmental pollution. Developed countries have high requirements for the environment, so most enterprises also demand to achieve "zero emissions". Now, there are reflections in the coastal areas of Guangdong and the middle and lower reaches of the Yangtze River. With the enrichment of social material resources, the requirements for the environment are also increasing. I believe that more and more enterprises will achieve zero discharge of industrial wastewater.
