Whether it is a power plant or other plants, I believe that as long as it is in production, wastewater will be generated. In response to the national call for green environmental protection, it is necessary to treat wastewater. So how can power plants achieve zero discharge of wastewater?

1. Zero discharge processing technology for power plant wastewater

Basic solid-liquid separation equipment is used to treat flue gas desulfurization wastewater using wastewater preparation equipment. The wastewater is directed into the exhaust duct behind the air preheater and in front of the dust removal equipment. After being atomized by a dual fluid dynamics electronic smoke atomizer with a high aspect ratio, under the heating effect of high-temperature flue gas waste heat recovery, the water is completely evaporated into liquid phase water vapor, and the salt is evaporated and crystallized into solid particles along with the water, which are captured by the dust removal equipment into dry ash, exceeding the goal of "killing" the wastewater. Moreover, it has significantly increased the humidity of the smoke and dust environment, improved the efficiency of dust removal equipment, and reduced the use of water in the flue gas desulfurization and desulfurization tower processing process, resulting in significant water conservation, environmental protection, and energy conservation, and maintaining zero discharge of flue gas desulfurization wastewater.

2. Production and manufacturing adjustment of the company

The company is required to regulate and improve production and manufacturing, save water resources, and improve the utilization rate of the production and manufacturing tap water circulation system. Various wastewater should be separated and prepared for treatment, and the amount of wastewater treatment at the tail end should be minimized as much as possible.

3. System software and equipment rectification

Rectify the current wastewater treatment system software. The wastewater treatment system software uses traditional organic chemical settling processing technology, which is technically feasible. However, due to the many years of operation of the solution system software, it is necessary to upgrade the machine equipment and further improve the level of automation technology.

4. Wastewater recycling and utilization system

Reuse wastewater that exceeds environmental standards through recycling system software for reuse in electroplating production lines. The company has adopted reasonable measures to save water resources in production and manufacturing, such as adjusting the positions of the plating tank and cleaning pool; Adjust the concentration value of the plating bath to the appropriate level; Choose the methods of reverse flow cleaning and self spray cleaning; Any wastewater that exceeds environmental standards after resolution will be immediately returned to the production and manufacturing modules before use.
