The first step, pretreatment, is crucial for the Power Plant Industry Wastewater Treatment Equipment. It's essential to eliminate the "obstacles" first. Coal ash and suspended solids from coal transportation and ash flushing are poured into a sedimentation tank, where they settle to the bottom. Oily wastewater from leaks in the oil system is also easily handled; a dissolved air flotation unit removes the oil droplets, which are then skimmed off. For acidic water from boiler cleaning or other alkaline wastewater, a neutralization tank precisely adjusts the pH to neutral, preventing corrosion of subsequent equipment. For difficult-to-decompose substances in desulfurization wastewater, an iron-carbon tower combined with advanced oxidation equipment is used to tackle the tough contaminants, making subsequent treatment easier.
The intermediate biochemical treatment is the core of organic matter removal. For power plant wastewater with relatively low organic concentrations, an MBR membrane bioreactor works well. It aerates the water, allowing microorganisms to "eat" the pollutants, while simultaneously filtering the water through a membrane, resulting in water with almost no suspended solids. If the wastewater concentration is high, an anaerobic reactor is used, which not only treats the wastewater but also produces biogas as fuel, making it environmentally friendly and cost-effective – a win-win situation.
Finally, after advanced purification, the water can be recycled. After ultrafiltration and reverse osmosis treatment, all the salts are removed, making it suitable for boiler feedwater. Further filtration with activated carbon removes any remaining odors and organic matter, and UV disinfection ensures safer use. The water quality indicators after treatment with the Power Plant Industry Wastewater Treatment Equipment are very stable, with COD controlled between 50 and 100, and suspended solids between 10 and 30, fully meeting emission standards and eliminating concerns about environmental inspections.

The most thoughtful aspect of this Power Plant Industry Wastewater Treatment Equipment is its ability to be customized to meet the specific needs of each power plant. For smaller sites, we use skid-mounted systems, like building with LEGOs – whatever's most convenient. If there's desulfurization wastewater, we add a heavy metal removal module to specifically address that problem. And it's all automatically controlled; pH levels and pollutant concentrations are monitored in real time, and the chemicals are added with extreme precision. There's no need for constant human supervision, saving labor and preventing wasted chemicals, resulting in significantly lower operating costs.
Speaking of which, Wuxi Jingbo Environmental Protection Technology Co., Ltd. truly understands the practical needs of power plants in the design of this Power Plant Industry Wastewater Treatment Equipment. Both the treatment efficiency and adaptability are excellent. Power plants that have used our equipment know that it's not only reliable, but also easy to maintain. Even if there are higher requirements for treatment effectiveness, Jingbo can adjust the solution according to the actual situation, truly helping power plants solve their wastewater treatment concerns and eliminating worries about this issue.
