Embodiment Construction

[0016] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0017] Such as Figure 1-6 The device for treating a sewage pond includes a filter area 1 , an aeration area 2 and a sedimentation area 3 . The filter area 1 is provided with a sewage tank 4, and the sewage tank 4 is provided with a sewage pipe 5. A triangular bracket 20 is provided outside the filtering area 1 , and the triangular bracket 20 supports the sewage tank 4 . The fixed area between the sewage box body 4 and the filter area 1 is small, and the sewage box body 4 is easy to come off from the filter area 1, so a triangular bracket 20 is set between the filter area 1 and the sewage box body 4 to increase the fixed area, so that A part of the force borne by the sewage tank 4 can be shared on the filter area 1, increasing the firmness of the sewage tank 4 on the filter area 1, so that the sewage tank 4 can discharge sewage into t...

Abstract

The invention mainly discloses a device for treating a sewage tank. According to the technical scheme, the device comprises a filter area, an aeration area and a settling zone, wherein a filter frame is fixedly connected with the filter area; a filter screen is arranged in the filter frame; an aeration device is arranged at the bottom of the aeration area; a support frame is arranged in the aeration area; a limiting block is arranged at the bottom of the support frame; a rotating rod is arranged on the limiting block; the rotating rod is rotationally connected with a turnover plate; the support frame is fixedly connected with a transverse plate; an elastic rope is arranged between the transverse plate and the turnover plate; a tilt table is arranged at the bottom of the settling zone; and a guide plate is fixedly connected to the side wall of the settling zone. The fluidity of sewage in the aeration area can be improved, transfer of oxygen in air to a liquid is accelerated, the oxygen supply rate in an aeration tank is improved, meanwhile, the content of solid particles in the treated water is reduced and the production quality of paper is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device for treating sewage pools. Background technique [0002] In the prior art, the pulp and water are mixed for anaerobic treatment, and the color of the effluent turns black. Generally, the sewage is treated through an aeration tank to make the sewage white, so as to avoid the impact on papermaking. The aeration tank is a structure that uses the activated sludge method for sewage treatment. A certain sewage residence time is provided in the pool to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. However, in the actual sewage treatment process, the fluidity of the aeration area is poor, the oxygen supply in the aeration tank is low, and the effect of purifying the sewage has not been achieved, and there are some solid particles in the water quality after the aeration tank, which affec...
