摘要
为提高化工园区环境治理水平,太湖流域某化工园区建设专业的污水处理厂用于处理化工废水。通过“一企一管,明管(专管)输送”方式收集园区内各企业化工废水后排放至园区专业污水处理厂,按照“分类收集、分质处理”的方式进行集中处理。污水处理厂设计规模为1.0×10^(4) m^(3)/d,其中有机化工废水采用“调节均质+水解酸化+AO生化+芬顿氧化+高效沉淀+活性炭原位吸附脱附”组合工艺处理,无机化工废水采用“调节均质+高效沉淀”工艺处理,出水水质能稳定达到《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》(DB 32/1072—2018)及《化学工业水污染物排放标准》(DB 32/939—2020)排放限值要求。平均废水处理成本约为8.466元/m^(3)。
To improve the environmental treatment level of chemical industrial park,a professional wastewater treatment plant was built to treat chemical wastewater in a chemical industrial park in Taihu basin.Chemical wastewater from all enterprises in the park is collected through“one enterprise one pipe and open channel or special pipe transportation”and discharged to the wastewater treatment plant,and treated based on the principle of“classified collection and treatment”.The design scale of the wastewater treatment plant is 1.0×104 m3/d.The organic chemical wastewater is treated by the combined process of regulating homogenization,hydrolytic acidification,AO biochemical process,Fenton oxidation,high efficient precipitation and activated carbon in-situ adsorption and desorption,while the inorganic chemical wastewater is treated by the process of regulating homogenization and high efficient precipitation.The effluent quality stably meets the limit specified in Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant&Key Industries of Taihu Area(DB 32/1072-2018)and Discharge Standard of Water Pollutants for Chemical Industry(DB 32/939-2020).The average wastewater treatment cost is approximately 8.466 yuan/m3.
