Chemical wastewater treatment

 Wastewater characteristics: chemical wastewater has complex components, many by-products, high pollutant content, more toxic and harmful substances, low B / C ratio and poor biodegradability.

Chemical waste water refers to the waste water produced in the production process of chemical plant products, such as the oily waste water from the production of ethylene, polyethylene, rubber, polyester, methanol, glycol, oil tank area, air separation and air compression station and other devices. After biochemical treatment, it can generally reach the national secondary discharge standard. Now, due to the shortage of water resources, the water that meets the discharge standard needs to be further treated After treatment, it can be recycled to meet the requirements of industrial water supply. Because the impurities in the water are mainly suspended particles and fine wool fibers, the microporous filtration technology is used to remove the impurities based on the principle of mechanical filtration. PLC or time relay control the working condition of filter equipment to realize automatic back washing and automatic operation. The water head required by the filter is provided by the lifting water pump, and the outlet water is directly introduced into the production system.

Treatment method: we use electro oxidation / electro flocculation – Microwave Catalysis – advanced oxidation as pretreatment, biological method as follow-up treatment process, which has low operation cost and good treatment effect, and realizes the effective treatment of chemical wastewater.

      We have different cases of mud pressing in mining industry in many countries. Welcome to visit our manufacturing workshop and work out a better sludge dewatering plan suitable for your company’s mining industry.Welcome to joyce@doyenchina.com or visit https://www.doyenchina.com.
