Since 2009, based on a series of survey 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 conclude the wastewater characteristics of chemical industries and draft the Effluent Standard drafts for this year. Besides, we drafted the E-coli effluent limitations for the slaughter industry and food industry as well as waste incinerators and other waste treatment plants (facilities) with animal wastes. Furthermore, we assessed the new regulations of the Steam Electric Power Generating Effluent Guidelines drafted by the US EPA. The rationality of effluent standards of COD for livestock industry (Applicable to cow) and electroplating industry (chromium) were reviewed and assessed. For leather tanning industries and printing, dyeing, and finishing industries, this project summarized the domestic and international literatures and the relevant reports of wastewater characteristics to draft the “Industry Wastewater Management Guideline” of the two industries. Besides, the wastewater characteristics of waste landfill were investigated and the “Document of the Wastewater Characteristic” was proposed. 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 wastewater background data of run-off wastewater and effluent acute toxicity as well as traced run-off wastewater elimination measures. Besides, we proposed the acute toxicity identification and reduction evaluation protocol as well as tested one real case. In the project, we concluded the calculation protocol and real cases for water quality based effluent limitations of the US EPA. The suggestions were then proposed.
