Example Embodiment
[0074] Example 1 Biofilm Reactor
[0075] The structure of the biofilm reactor is as figure 1 As shown, it includes an outer cylinder 11, an inner cylinder 12 arranged inside the outer cylinder 11, a semi-soft filler filled inside the inner cylinder 12, and a shale ceramsite filled between the outer cylinder 11 and the inner cylinder 12. The filter material is the aeration head that is arranged at the bottom of the outer cylinder 11 and communicated with the inner cylinder 12. The parameters of the biofilm reactor are as follows:
[0076] Outer cylinder: height 5.5m, diameter 2.8m, effective water depth 4.8m, effective volume 30.0m 3 , the hydraulic retention time is 1.5h;
[0077] Inner cylinder: 1.8m in diameter, the distance between the bottom of the inner cylinder and the bottom of the outer cylinder is 0.3m, and the distance between the top of the inner cylinder and the top of the outer cylinder is 0.3m;
[0078] The semi-soft packing is a semi-soft hanging packing pur...

[0080] Example 2 Wastewater Treatment System
[0081] The wastewater treatment system includes: a water diversion tube, a cyclone separator whose water inlet is connected to the water outlet of the water diversion tube, a lift pump whose water inlet is connected to the water outlet of the cyclone separator, and a water inlet connected to the water outlet of the lift pump. In the biofilm reactor provided in Example 1, the sloping plate precipitator whose water inlet is connected to the water outlet of the biofilm reactor, and the sludge return pump connected with the mud outlet of the sloping plate precipitator, use a Roots blower for aeration; wherein, The parameters of each device are as follows:
[0082] Water diversion cylinder: diameter 0.85m, length 1.17m, volume 0.66m 3 ;
[0083] Lift pump: flow 20.0m 3 / h, head 10.0m;
[0084] Cyclone separator: processing capacity 20.0m 3 / h~29.0m 3 / h, diameter 273mm, height 1350mm, head loss 4m ~ 5m;
[0085] Inclined plate s...
