大型地下市政+工业混合污水处理厂兼顾人防设计案例
- Title:
- Design Case of Large Underground Municipal and Industrial Mixed Wastewater Treatment Plant with Civil Air Defense Function
- Keywords:
- underground wastewater treatment plant; hydrolytic acidification; AAOA+MBR; ozone advanced oxidation; civil air defense
- 摘要:
- 杭州市临平净水厂设计规模为20×104 m3/d，采用全地下建设模式，根据其进水水质和COD组分分析，确定采用水解酸化+AAOA+MBR+臭氧高级氧化污水处理工艺，出水水质达到一级A排放标准。项目采用大空间对流通风、多模式除臭、污水源热泵、精确曝气、光导照明等多种新技术，同时结合人防防护要求和厂区工艺运行特点，将部分生产区按照人防要求进行平战转换设计，是目前国内首座人防+地下式污水处理厂。
- Abstract:
- Hangzhou Linping wastewater treatment plant is a complete underground wastewater treatment plant, and its designed treatment capacity is 20×104 m3/d. According to its influent quality and COD components analysis, a process of hydrolytic acidification, AAOA, MBR and ozone advanced oxidation was employed, and the effluent quality met national first level A discharge standard. Several new technologies were adopted, such as large space convection ventilation, multimode deodorization, sewage source heat pump, precise aeration system, tubular lighting and so on. Meanwhile, considering the requirements of civil air defense and the characteristics of process operation, part of the production areas were designed to be switched between peacetime usage and wartime usage, making it the first underground wastewater treatment plant with civil air defense function in China.
