The focus of this plan is on the international and domestic petrochemical industry effluent control, the current situation regarding biological wastewater acute toxicity, data collection of total toxic organics processing technology analysis of the sixth naphtha cracker district petrochemical industry, water quality, waste water treatment facility, swage mass balance map data, and the sixth naphtha cracker district petrochemical industry raw wastewater and effluent sampling plang. The Data show the foreign petrochemical effluent control are more stringent than those used domestically, regardless of cause. For example, china has different control standards which makes it difficult to compare performance with international standards. However, countries such as the U.S. and Germany continue to collect information on other countries effluent standards in order to better evaluate and reduce the toxicity of biologically activated carbon, ozone or activated sludge. The water quality analysis results show that Nan Ya Plastics Haifeng factory in biological acute toxicity of raw wastewater, in addition to the raw wastewater the Acute toxicity TUa of invertebrates <1.00 outside, the rest of the waste water treatment plant of raw wastewater spine with no spine biological acute toxicity TUa in referral1.81 to> 5.00; in effluent aspects, Formosa Petrochemical Mailiao factory, stage chemical fiber dimensional sea Fung factory (invertebrates), Taiwan the chemical fiber Weimai Laos Factory (invertebrates) and Mai-Liao Power Corporation biological acute toxicity mediated1.64 to 5.00, the rest of the wastewater treatment plant effluent biological acute toxic TUa of less than 1.0. The test results to the station chemical fiber the dimensional sea Fung factory and Nan Ya Plastics the Haifeng Plant of the TTO reduction rate is very good and Nan Ya Plastics the Mailiao Plant and Chang Chun Plastics Mailiao plant TTO and biological acute toxicity reduction showed significant efficiency , but the process of receiving water, the small number of samples was less than the effect of their specific assessment handler. This plan has try to combine the result of investigation and built standard, submit three proposal to restrict wastewater standard at biological acute toxicity and total toxic organics.
