Taiwan’s Environmental Protection Administration (EPA) has set the strategy behind Article 14-1 in the Water Pollution Control Act to fully understand the characteristics of wastewater discharged from specific industries and prevent as well as improve the risk management of non-regulated items in the Effluent Standards. The project analyzed three disclosure pollutants (N-Methyl-2-pyrrolidone, butadiene, and acrylonitrile) in industrial wastewater and proposed suggestion for the Effluent Standard regulations. The three disclosure pollutants have been used widely in specific manufacturing industries. Moreover, for metal finishing industry and textile industry, this project summarized both Taiwanese and international literatures, as well as relevant reports on wastewater characteristics to draft industrial wastewater management guideline for these two industries. On the other hand, we conducted one educational training course on the finalized guidelines. This project has revised the reinforcing strategies in the Effluent Standards based on industrial manufacturing and wastewater characteristics, including (1) the Effluent Standard for the industries that discharged effluent into the villages near reservoir and conservation storage within range; (2) the reinforced limitation on heavy metals for specific industries (such as the electroplating with the flowrate reach a certain scale); (3) the Effluent Standard draft for steam-electric power plant; (4) management assessment regulation for nonylphenol, microbead, and ammonia nitrogen. Further, we traced the effluent quality of the industries that have revised Effluent Standards and the implementation of their Effluent Pollutant Elimination Management Plans.
