Description

technical field [0001] The invention belongs to the field of organic wastewater treatment equipment, in particular to an integrated treatment of refractory organic wastewater and a method for treating refractory organic pollutants in organic wastewater by using the equipment. Background technique [0002] With the continuous development of modern industry, a large number of organic compounds are widely used in human production and life, and various wastewater containing organic pollutants that are difficult to biodegrade also increase. These wastewaters generally have the characteristics of high pollutant concentration, high toxicity, and poor biodegradability, which have caused serious pollution to the water environment and directly threatened human health. [0003] At present, physicochemical, chemical, and biochemical methods are often used to treat such refractory organic wastewater. However, due to the particularity of water quality, conventional treatment technologies ...
