We are specialized in the treatment and utilization of organic poisonous wastewater released from chemical plants. Supported by departments at all levels, we have developed dozens kinds of complexation resins, adsorption resins and hypercrossing resins with different aperture and polarity, which have been applied effectively in the treatment of nearly one hundred kinds of wastewater in the past ten years. The industrialized equipments have been running successively in more than ten companies such as Nanjing Chemical plant. Using resin adsorption in the treatment of the organic poisonous wastewater combines the developement and manufacture of resin，the treatment and utilization of wastewater, and achieves environmental benefit as well as social and enconomic benefit.
