- Abstract:
- Combined with the experience of upgrading and reconstruction of the three wastewater treatment plants in Fuzhou, the improvement of biochemical treatment process, the key points of advanced treatment process selection, and the characteristics of upgrading and reconstruction of sewage treatment plants in southern cities are put forward, and the development direction of upgrading and reconstruction process is prospected. According to the biochemical treatment process, influent quality, regional environmental functions and operation conditions of the three sewage treatment plants, different facilities transformation and standard raising processes are adopted. Based on the existing process of three wastewater treatment plants, the high-efficiency sedimentation tank was selected as coagulation sedimention process, denitrification deep bed filter, fiber rotary disc filter and active sand filter were employed as filtration process, respectively. Through the technical upgrading and management optimization of the current process, the effluent quality of the three wastewater treatment plants could meet the requirement of the first level A standard steadily. The selection of advanced treatment process according to local conditions should be in line with the actual situation.
