Solution for Difficult to degrade Wastewater

Some specific industries may generate recalcitrant wastewater during production, and the organic pollutants in this wastewater are difficult to biodegrade, such as organic phosphorus wastewater, coking wastewater, antibiotic wastewater, etc. For this type of wastewater, it is necessary to first use physical and chemical processes to improve the biodegradability of the wastewater, and then carry out biochemical treatment. These processes mainly include physical methods such as adsorption, extraction, and precipitation, as well as advanced oxidation technologies such as Fenton, electrocatalytic oxidation, and catalytic wet oxidation. For this type of wastewater, our company has developed adsorption, extraction, catalytic oxidation and other devices combined with biochemical processes to solve the problem of difficult and costly treatment of this type of wastewater.
