- Abstract:
- The Jinganghe underground reclaimed water plant in Fuzhou is the key project of comprehensive control of Jingang River water environment. The design scale is 5 000 m3/d, and it is built together with a 5 000 m3 rainwater storage tank. The plant was constructed underground in the project, and a landscape park was created on the ground. The hybrid biofilm reactor (HBR) process was employed as the core biological treatment process. The process can realize the dual functions of biofiltration and biofilm treatment and replace the secondary sedimentation tank by forming a fixed bed with high filling rate of the fillers, thus solving the difficult problems of limited footprint and high effluent quality requirements. The main indicators of the effluent are better than the first class A discharge standard. The high quality tail water was discharged as the ecological water replenishment for Jingang River and effectively solves the problem of black and odorous water in the river.
