- Title:
- Design of Wastewater Treatment System for a Solid Waste Comprehensive Disposal and Utilization Center in Qingdao
- Keywords:
- hazardous waste; wastewater treatment; MBR; RO; three-effect evaporation process
- 摘要:
- 青岛某固体废物综合处置利用中心采用焚烧、物化、稳定化/固化以及填埋等工艺处理危险废物。由于危废种类多、成分复杂，并且每种危废处理工艺产生的废水污染物成分不同，因此增加了废水处理的难度。基于对各种危废处理工艺系统排水、厂区冲洗排水、生活污水以及初期雨水等的水质特点的分析，将全厂废水分成有机物废水和高盐废水两大类，分开收集，分质处理。有机物废水处理规模为200 m3/d，采用 “气浮+还原+中和+絮凝沉淀+水解酸化+A/O+MBR+RO”组合处理工艺;高盐废水处理规模为150 m3/d，采用三效蒸发处理工艺，确保出水水质稳定达到《污水排入城镇下水道水质标准》（GB/T 31962—2015）B级标准和园区污水处理厂接管标准。整个废水处理系统总投资为1 759.10万元，运行成本约为19.5元/m3。
- Abstract:
- A solid waste comprehensive disposal and utilization center in Qingdao uses incineration, physicochemical, stabilization/solidification, and landfill processes to deal with hazardous waste. Because there are many types of hazardous wastes and complex composition, and the composition of wastewater pollutants produced by each hazardous waste treatment process is different, which increases the difficulty of wastewater treatment. Based on the analysis of the water quality characteristics of various hazardous waste treatment process system drainage, factory flushing drainage, domestic sewage and initial rainwater, etc., wastewater of the whole plant was divided into two categories: organic wastewater and high-salt wastewater. The different wastewater was collected separately and treated separately. The organic wastewater treatment scale is 200 m3/d, adopting “air floatation+reduction+neutralization+flocculation and precipitation+hydrolytic acidification+A/O+MBR+RO” combined treatment process. The treatment scale of high-salt wastewater is 150 m3/d, the three-effect evaporation process is adopted. The treatment process ensures that the effluent steadily meets the Class B standard of Wastewater Quality Standards for Discharge to Municipal Sewers (GB/T 31962-2015) and the takeover standard of sewage treatment plant in the park. The total investment of the entire wastewater treatment system was 17.591 million yuan, and the operating cost was about 19.5 yuan/m3.
