Embodiment Construction
[0014] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0015] Such as figure 1 As shown, the aerobic precipitation integrated bioreactor of the present invention includes an aerobic pool 1 and a sedimentation area 2 located at the bottom of the aerobic pool 1; The wall is a hollow cavity 3, that is, the inner and outer walls of the sedimentation area 2 are surrounded by a hollow structure. The hollow cavity 3 is a muddy water channel. There is a muddy water inlet 4 on the outer wall of the sedimentation area 2, and a muddy water inlet 4 is opened on the inner wall of the bottom of the sedimentation area 2. Water discharge port 5; the aerobic sedimentation integrated bioreactor of the present invention also includes a circulation mud discharge pipe 6, the mud inlet of the circulation mud discharge pipe 6 extends into the hollow cavity 3, and the mud discharge port of the circulation mud discharge p...

The invention discloses an aerobic precipitation integrated bioreactor. The integrated bioreactor comprises an aerobic tank and a precipitation area positioned at the bottom of the aerobic tank; the top of the precipitation area is open, the side wall of the precipitation area is a hollow cavity which is a muddy water channel, a muddy water inlet is formed in the outer side wall of the precipitation area, and a water outlet is formed in the inner side wall of the bottom of the precipitation area; and the integrated bioreactor further comprises a circulating sludge discharge pipe, the sludge inlet of the circulating sludge discharge pipe extends into the hollow cavity, the sludge discharge port of the circulating sludge discharge pipe is located in the aerobic tank, and a gas stripping device is arranged on the circulating sludge discharge pipe. According to the integrated bioreactor disclosed by the invention, the precipitation area is arranged at the bottom of the aerobic tank, and meanwhile, sludge sucked from the precipitation area by the sludge discharge pipe is discharged into the aerobic tank through the gas stripping device; and the integrated bioreactor disclosed by the invention can effectively improve the concentration and activity of sludge in the aerobic tank, and cannot generate dead angles of the sludge, so that the sedimentation of a sludge-water mixed solution and the mixing of microorganisms, water and oxygen can be accelerated, and the water treatment effect of the aerobic tank is further improved.
Description
technical field [0001] The invention relates to an aerobic precipitation integrated bioreactor, which belongs to the technical field of water treatment. Background technique [0002] In the existing sewage treatment system, the aerobic pool and the sedimentation area are set separately. After the sludge in the aerobic pool is naturally settled, it is pumped into the sedimentation area through the sludge pump. in the oxygen pool. In the above-mentioned setting method, the sludge in the aerobic tank adopts the natural sedimentation method. On the one hand, the sedimentation efficiency is low, and on the other hand, the sludge concentration in the aerobic tank is low, and there is also the problem of sludge dead ends. Contents of the invention [0003] The present invention provides an aerobic sedimentation integrated bioreactor aiming at the problems of low sedimentation efficiency, low sludge concentration and sludge dead ends in the aerobic pool in the prior art when the ...
