Adsorption resin for coking wastewater treatment

Coking wastewater is a typical toxic refractory organic wastewater.Coking wastewater mainly comes from coke oven gas primary cooling and coking process production water and steam condensing wastewater.Due to the high concentration of pollutants in coking wastewater, it is difficult to degrade. Due to the existence of nitrogen in coking wastewater, the nitrogen source required for biological purification is excessive
