According to the investigation of wastewater characteristics for specific industries, the Environmental Protection Administration (EPA) has revised and set the Effluent Standards for High-technology Industry and Petrochemical Industry from 2009. This study not only keeps tracking the effluent quality and the results of the Effluent Pollutant Elimination Management Plan, but also analyses the wastewater characteristics of chemical industry and industries bearing polybrominated diphenyl ethers or ammonia. The plan has revised and set the Effluent Standard for dioxin, chemical engineering industry and ammonia-nitrogen. Moreover, this study has summarized the domestic and international references and the wastewater characteristics as well as drafted the “Industry Wastewater Management Guideline” for wafer and semiconductor manufacturing industry and electroplating industry. At the same time this study has surveyed the wastewater characteristics of laundry, dialysis center and metal surface treatment industry with the rod as the raw material. The aim of this study is to accomplish the effective pollutant management of industry wastewater and fulfill the wastewater management mechanism for various industries. The plan has helped the EPA to promote the management strategy and implementation procedure for leakage prevention management of wastewater pit, run-off wastewater elimination management and effluent acute toxicity management for specific industries. The plan has analyzed and drafted the management of residual building sand stone, monitoring and reporting project, permit review guideline, permit of storage leakage management and guideline of water-quality-based effluent limitations as well as promoted the management suggestions. Furthermore, the plan also investigates the appropriateness of regulations and standards for specific industries or items (such as pollution prevention for rendering plants, the COD standard for livestock industry applicable to cows, the chromium compounds standard for leather tanning industry).
