- 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.
