摘要:
浙江某大型综合化工园区污水处理厂(20×104 m3/d)服务范围既包括化工工业园区，又包含城区居住区，提标前进厂水中工业废水量约占54%，出水统一执行《污水综合排放标准》(GB 8978—1996)一级标准，尾水排入杭州湾。提标工程设计采用将生活污水与工业废水分开收集、分质处理提标的总体方案。将现状处理线拆分、改造为两条独立的10×104 m3/d规模处理线，一条用于生活污水提标处理，改造方案为在现状二级生化/高效沉淀池基础上增加纤维转盘滤池，处理后尾水达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。另一条用于工业废水提标处理，改造方案为在现状絮凝沉淀/水解酸化/二级生化基础上增加催化芬顿+活性炭吸附工艺，处理后尾水达到《污水综合排放标准》(GB 8978—1996)一级标准（COD≤80 mg/L）。提标改造新建设施占地2.87 hm2，全部利用厂内空地。提标改造完成后，两条线均运行良好，出水稳定达标。生活污水部分改造吨水投资约117元/m3，运行费用在原基础上增加0.08 元/m3。工业废水部分改造吨水投资为1 920 元/m3，运行费用在原基础上增加3.48 元/m3。
Abstract:
The service area of a wastewater treatment plant (treatment capacity of 20×104 m3/d) in a large comprehensive chemical park in Zhejiang Province covers both the industrial park and urban residential area. Before upgrading, the percentage of industrial wastewater in the influent of the plant is about 54%. The effluent quality need to meet the first degree criteria specified in Integrated Wastewater Discharge Standard (GB 8978-1996), and the tail water is discharged into Hangzhou Bay. In the upgrading project, the overall scheme of separate collection and treatment of the domestic sewage and industrial wastewater was determined. The existing treatment process was split and transformed into two independent treatment processes with the treatment capacity of both 10×104 m3/d. One process was used for domestic sewage upgrading. The upgraded plan was to add a fiber rotary filter on the basis of the existing secondary biochemical treatment and high-efficiency sedimentation tank, in which the effluent quality reached the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Another process was used for industrial wastewater upgrading treatment. The transformation scheme was to add a process of catalytic Fenton and activated carbon adsorption on the basis of the current process of flocculation and sedimentation, hydrolysis acidification and secondary biochemical treatment, and the effluent quality reached the first degree criteria specified in Integrated Wastewater Discharge Standard (GB 8978-1996) (COD≤80 mg/L). The newly built facilities for upgrading covered a footprint area of 2.87 hm2, all of which were made use of the open space in the plant. After the upgrading, the two processes run well, and the effluent quality is stable and reaches the national discharge standard. The investments of the domestic sewage and industrial wastewater upgrading projects are approximately 117 yuan/m3 and 1 920 yuan/m3, and the operating costs are increased by 0.08 yuan/m3 and 3.48 yuan/m3 on the original basis, respectively.
