Abstract:
Huashan Wastewater Purification Plant is the first underground wastewater treatment plant in Jinan. The plant is located in Huashan Lake scenic area with a footprint area of 1.96 hm2. The designed treatment capacity was 3×104 m3/d, and the total investment was 176 million yuan. Sewage and sludge treatment unit, dosing room, blower room and other auxiliary units are built in the underground box. The underground box is divided into two layers, namely the first floor underground (maintenance layer) and the second floor underground (structure layer). The ground area is planned to be a green landscape. The treatment process consists of pre-treatment, AAO, MBR and UV disinfection. The COD, BOD5, NH3-N and TP in the effluent meet the class Ⅳ criteria specified in Environmental Quality Standards for Surface Water (GB 3838-2002), and other indices meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The effluent is discharged as landscape water to supplement the lake water in the scenic area.
