Technical features of Bettow:

Especially for high-concentration waste liquids such as waste emulsions (oils), cutting fluids and grinding fluids produced in the production process of machinery processing, automobile manufacturing, surface treatment and other industries. Aiming at the characteristics of high pollutant concentration, high salt content and low amount of waste water in the relevant waste liquid, low-temperature evaporation is used for pretreatment to separate waste water and a small amount of organic matter from the waste liquid. Using low-temperature evaporation, on the one hand, is beneficial to save energy consumption, on the other hand, it is beneficial to reduce the concentration of pollutants in the distillate and reduce the difficulty of subsequent distillate processing. For the distillate, the "flocculation-air flotation" + "efficient biological treatment" process is used for advanced treatment, and the "flocculation-air flotation" further reduces the pollutants in the wastewater and reduces the composite of the subsequent biochemical treatment system; the subsequent biochemical treatment system Considering the characteristics of pollutants such as mineral oil in the relevant waste liquid, the MBR process based on special membrane materials is selected to enhance the biological treatment effect while further enhancing the anti-fouling performance of the membrane to ensure that the membrane treatment effluent can reach level 1A At the same time as the standard, and can maintain a higher throughput. In addition, for the distillate, the process of "activated carbon adsorption" + "ultrafiltration + reverse osmosis" can also be used. Through the adsorption of activated carbon, the concentration of pollutants in the distillate can be further reduced to ensure the efficient and stable operation of the subsequent reuse system. In the follow-up "ultrafiltration + reverse osmosis" process, the produced water is reused in the front-end production process, and the RO concentrated water is reused in the waste liquid storage tank, ultimately achieving zero discharge of wastewater. Through the research and integration of key technologies for the emission reduction of pollutants in the waste emulsion (oil), the advanced treatment and reuse of the waste emulsion (oil) can finally be realized according to the scale and emission requirements of the enterprise. Relevant process technology and processing units can also be equipped to form an integrated waste emulsion (oil) processing equipment and a mobile processing platform.
