Organic wastewater is mainly composed of organic pollutants. Because organic wastewater is easy to cause water eutrophication and has great harm, it needs to be treated by integrated sewage treatment equipment.
Ultrasonic degradation uses ultrasonic technology to degrade organic pollutants in water, especially those difficult to degrade. Ultrasonic degradation technology is a new water pollution control technology rising in the 1990s.
Treatment method - oxidation adsorption method after diluting the high concentration wastewater, it needs to be coagulated and adsorbed with pulverized coal initially, then it is catalyzed, oxidized and acid coagulated with Fenton reagent, and then the pulverized coal is used for coagulation and adsorption again. The waste water treated by this method is burned by adsorbed pulverized coal without secondary pollution, which is more economical than using activated carbon as absorbent.
Concentration method is to evaporate most of the water and concentrate and separate pollutants through the low solubility of some pollutants. The concentration method has the advantages of simple operation and mature process, and can realize the partial recovery of useful substances. It is suitable for the treatment of salty organic wastewater.
Physicochemical methods are often used in the pretreatment of organic wastewater. The purpose of pretreatment is to remove the useful components in the recovered wastewater or the organic substances in the products that are difficult to degrade, so as to improve the biodegradability and treatment efficiency and reduce the biochemical treatment load.
