Background

The SBR+MBBR technology (intermittent activated sludge process+moving bed biomembrane reactor) is a novel energy-saving sewage biochemical treatment system and has the advantages of less sludge, stable operation, small occupied area and the like. The SBR reaction tank is added with a certain amount of suspended filler, wherein the suspended filler is also called porous rotary spherical suspended filler, is a new material developed from various fillers adopted in domestic sewage and biomembrane treatment technologies, is generally provided with a spherical structure with a certain diameter, and effluent continuously flows through the suspended filler and gradually forms biomembranes on the inner surface and the outer surface of the filler, so that microorganisms on the biomembrane can purify sewage. The suspended filler moves freely in the reactor, but because the density of the filler is close to that of water, the filler flows out to other structures along with the water during stirring or aeration, so that the filler is lost, a pipeline is blocked, even an SBR decanter is damaged, and the normal water discharge of the system is affected.

The filler interception device generally requires high hydraulic load bearing capacity, good interception effect, strong deformation resistance, small equipment investment and stable operation. In the prior art, a transverse pulling type is generally adopted in a rectangular pool, but under the condition of higher overcurrent intensity, the structure is unstable, and the flow rate of the water is too low. The SBR reaction tank is mostly a round steel tank, the largest water passing area of the filler filtering device is theoretically arranged on the diameter part, but when the SBR reaction tank is arranged at the position, the MBBR filler is only used on one half part of the effective volume of the SBR tank, and the filler and pollutants in sewage do not fully contact and react, so that the denitrification and decarbonization effects are affected, and the treatment efficiency of the MBBR process is reduced. Therefore, under the condition of the largest water passing area, the suspended filler can be intercepted, the treatment efficiency of the MBBR process is ensured, the mechanical structure is more stable, and the subsequent treatment equipment can be protected, so that the method is a technical problem which needs to be solved by a person skilled in the art.
