Since 2010, based on a series of surveys on industrial wastewater characteristics, the Environmental Protection Administration (EPA) has amended the Effluent Standards of high-technology industries and petrochemical industries. In this project, we traced the effluent quality of the two industries and the implementation of their Effluent Pollutant Elimination Management Plans. The second focus was to investigate the wastewater characteristics of steam electric power plant and conclude the new regulations of the Steam Electric Power Generating Effluent Guidelines drafted by the US EPA. The Effluent Standard drafts for steam electric power plant were proposed. Besides, this project was to assess the wastewater characteristics of industries using ammonia-bearing substances and with the discharge concern of true color. We suggested the priority of the Effluent Stnadard regulation for ammonia nitrogen and the strengthened limitation of true color for the specific industries. Besides, we considered the effluent standard of a variety of countries and proposed the suggestion of the strengthened limitation based on the receiving water quality or specific areas. For metal manufacturing industries and paper manufacturing industries, this project summarized the domestic and international literatures, as well as the relevant reports of wastewater characteristics to draft the “Industry Wastewater Management Guideline” of these two industries. Besides, we compared the requirements in “Petrochemical and Cheical Industry Wastewater Management Guideline” and the discharge permits of some industries to analyze the difference. We conducted three education and training courses of the finalized guidelines. For the run-off wastewater elimination and effluent acute toxicity control of the “Water Pollution Control Measures and Test Reporting Management Regulations”, we accumulated the background data of industrial wastewater, run-off wastewater and effluent acute toxicity. In the project, we proposed the suggestion of sludge reduction management rule for the specific factories with the wastewater amount higher than some specific value.
