Background

Among the current sewage treatment methods, the activated sludge method is still the most widely applied secondary biological treatment process in all countries in the world. After the sewage is subjected to secondary biochemical treatment in the aeration tank, the sewage generally needs to enter a secondary sedimentation tank for sludge-water separation, and clear water is disinfected and discharged. Because the aeration tank needs to be inoculated with microorganisms, sludge needs to flow back to the aeration tank from the secondary sedimentation tank. Two modes, pump reflux and gas lift (gas lift) reflux, are generally adopted for refluxing or discharging sludge. The pump backflow has the advantages that the flow and the pressure are controllable, the backflow ratio can be accurately controlled, but the impeller rotating at a high speed can break sludge flocs, and zoogloea is damaged to a certain extent, so that the activity and the settleability of sludge are reduced. The gas lifting reflux does not damage sludge flocs, is very favorable for maintaining the activity and settleability of the sludge, and simultaneously reduces energy consumption.

However, the existing gas lift reflux device has the following defects:

(1) the gas lifting reflux device is generally arranged underwater in the pool, and is difficult to overhaul when the gas lifting reflux device fails;
