Technical scheme of ultrasonic cleaning wastewater treatment equipment
Efficient sewage treatment equipment combining biotechnology and physicochemical technology. Its technical core source is the combination of composite biochemical technology and catalytic oxidation technology. This process not only effectively achieves the purpose of removing high-concentration COD, ammonia nitrogen and desalted wastewater, but also has incomparable advantages over the traditional secondary sewage treatment process. Compared with the traditional biochemical water treatment technology, the ultrasonic cleaning wastewater treatment equipment (catalytic oxidation-biological fluidized bed) produced by Yixing Enyue has the following main characteristics: high treatment efficiency and good effluent quality; Compact equipment and small floor space; Easy to realize automatic control, simple operation and management, low investment cost of key processes, economical operation, convenient operation, energy saving and consumption reduction.
Traditional wastewater treatment methods mainly include biological method, physical method and chemical method. However, biological methods, including anaerobic processes, take a long time, and it is difficult to reduce their toxicity and produce many more toxic products. Physical methods include electrocoagulation, adsorption, membrane separation and flocculation, which are usually not applicable. Chemical methods, such as photocatalytic degradation and ozone oxidation, will not bring secondary pollution, but the treatment time is longer and the cost is higher. Ultrasonic wastewater treatment technology has become one of the focuses of environmental workers in recent years, and it is favored by researchers because of its advantages of rapidity, high efficiency and no secondary pollution. The cavitation effect of ultrasound provides the possibility to degrade harmful organic substances in water, thus achieving the purpose of ultrasonic treatment of organic wastewater. In the process of organic wastewater treatment, ultrasonic cavitation has a strong ability to degrade organic matter, and the degradation speed is very fast. The high energy produced by ultrasonic cavitation bubble collapse is enough to break the chemical bond, and the cavitation bubble collapse produces hydroxyl and hydrogen groups, which react with organic substances in oxidation. Yixing Enyue Environmental Protection can convert harmful organic substances in water into inorganic ions or organic substances which are less toxic and more degradable than the original organic substances. Therefore, in the traditional organic wastewater treatment, the organic pollutants that are difficult to treat can be degraded by ultrasonic cavitation, while the wastewater produced by ultrasonic cleaning machine still contains many impurities, oils and other substances, which need further treatment.
