- 摘要:
- 石化废水成分复杂，含有大量难降解和毒性强的有机物，水质水量变化大。东营港某石化废水处理厂扩建工程一期规模为2.5×104 m3/d，采用水解酸化工艺改善废水的可生化性，同时对原水的水量、水质起到调节作用；采用固定生物膜-活性污泥（IFAS）工艺有效去除COD，同时脱氮除磷；采用磁混凝沉淀-臭氧催化氧化-活性焦吸附深度处理工艺，进一步去除废水中SS、TP、难降解有机物、色度。实际运行结果表明，出水COD、NH3-N、TP达到《地表水环境质量标准》（GB 3838—2002）的Ⅳ类标准，出水TN≤12 mg/L，其余指标达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级A标准。
- Abstract:
- Petrochemical wastewater has complex composition, contains a large amount of refractory and toxic organics, and fluctuates greatly both in quality and quantity. The first?stage capacity of the expansion of a petrochemical wastewater treatment plant in Dongying Port is 2.5×104 m3/d. Hydrolysis acidification is used to improve the biodegradability of the wastewater, and simultaneously regulates the quantity and quality of raw water. IFAS process is used to effectively remove COD, nitrogen and phosphorus. The advanced treatment process adopts magnetic coagulation sedimentation, catalytic ozonation and activated coke adsorption to further remove SS, TP, refractory organics, and chromaticity. The actual operation results show that the effluent COD, NH3-N, and TP can meet the level Ⅳ criteria specified in Environmental Quality Standards for Surface Water (GB 3838-2002), the effluent TN can be less than 12 mg/L, and the other indicators can meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
