Embodiment 1
[0031] Take the effluent from the primary sedimentation tank of a city sewage treatment plant in winter as the influent water, the water temperature is 12-15°C, the concentration of BOD in the water is 165-180mg / L, the concentration of ammonia nitrogen is 30-40mg / L, the concentration of TN is 35-50mg / L, and the concentration of TP is 2- 3mg / L. Reactor effective volume 3.0m 3 , of which 1.2m in zone A 3 , 1.8m in zone B 3 . The specific surface area of the suspended filler used is 620m 2 / m 3 , the filling rate is 20%, and the specific gravity before filming is 0.98. The design operation cycle is: water inflow 2h, reaction 1h, precipitation 0.5h, decanting water 0.5h. Single water change 0.8m 3 .
[0032] When starting up, the return sludge of the water plant is used as inoculation sludge, and new suspended filler is added. In the start-up phase, the single water change volume is 0.4m 3 . After 3 days of start-up, the filler is wetted and begins to hang the film, a...
Embodiment 2
[0034] Take the effluent from the primary sedimentation tank of a sewage treatment plant in winter as the influent, the water temperature is 12-15°C, the concentration of BOD in the water is 125-150mg / L, the concentration of ammonia nitrogen is 32-44mg / L, the concentration of TN is 37-50mg / L, and the concentration of TP is 2-3mg / L. Reactor volume 5.4m 3 , of which 2.4m in zone A 3 , 3.0m in Zone B 3 . A total of 2 monomer reactors are operated alternately. The specific surface area of the suspended filler used is 620m 2 / m 3 , the filling rate is 25%, and the specific gravity before filming is 0.98. Due to the lack of carbon source in the water, a carbon source dosing device is installed in Area A to supplement the carbon source during the water inflow and reaction stage. The design operation cycle is: water inflow 2h, reaction 1h, precipitation 0.5h, decanting water 0.5h. 2 reactors alternately feed water to realize continuous water inlet and outlet operation, with...
