Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, the present invention provides a two-way flow aerated biological ecological pool. The pool body is provided with a biological purification area, a flocculation area, a sludge concentration area, a sedimentation area and a top ecological area, and a side ecological area is provided outside the pool body. The biological purification area and the flocculation area are sealed structures, and the flocculation area is located on one side of the biological purification area and communicated with the biological purification area through a connecting pipe 22, so that the purified sewage at the bottom of the biological purification area is introduced into the flocculation area through the connecting pipe 22; The area is connected with the sludge concentration area and the sedimentation area, so that the sewage in the flocculation area enters the sedimentation area through the sludge concentration area; the top ecological area is set on the t...

Embodiment 2

[0038] Such as Figure 2 to Figure 4 As shown, in combination with the technical solution of Embodiment 1, in this embodiment, the breathable and water-permeable device 20 includes a pipe body 201, an air collecting cover 202, a spherical channel 203 and a small ball 204, and the pipe body 201 is arranged on the filter plate 21, and the pipe body 201 One end of the body 201 is provided with a semicircle cover 205, and one end of the semicircle cover 205 and the pipe body 201 is provided with a plurality of water passage holes 207, and the semicircle cover 205 is positioned above the filter plate 21, so that the passage on the semicircle cover 205 The water hole 207 is located above the filter plate 21, and the water hole 207 on the pipe body 201 is located below the filter plate 21; the sewage purified by the filter filler 30 enters the bottom of the filter plate 21 from the water hole 207; There is an air-collecting passage 206, the spherical passage 203 communicates with one...

Embodiment 3

[0041] Such as figure 1 As shown, in combination with the technical solutions of Embodiment 1 and Embodiment 2, in this embodiment, a sludge return pipe 14 is also included, and the sludge return pipe 14 is respectively connected to the sludge concentration area and the return pipe 12. The sludge return pipe The sludge discharge pipe 15 is also connected with the bottom of the top ecological zone on the top 14, and the sludge discharge pipe 15 is provided with a valve ten 10, so as to pass through the valve ten ten 10 to accumulate a certain degree of sewage in the sludge concentration zone and the bottom of the top ecological zone. Mud is discharged.

[0042] Further, the valve three 3 is located at the back end of the valve four 4 and the valve five 5, the valve six 6 is located at the front end of the valve four 4 and the valve five 5, and the sludge discharge pipe 15 is connected to the sludge return pipe 14 at the front end of the valve five 5, By closing the valve 5, op...

Abstract

The invention discloses a two-way flow aeration biological ecological pool, which comprises a pool body, in which a biological purification area, a flocculation area, a sludge concentration area, a sedimentation area and a top ecological area are arranged, and a side ecological area is arranged outside the pool body , high integration, compared with the separate construction of each functional unit, the floor area and engineering cost are greatly reduced; and the biofilter is alternately in two operating modes of upflow and downflow, making full use of the role of biological purification ; The backwash water is purified inside the filter, the system itself has a small amount of sewage, and the equipment operates normally during the backwash of the filter, which improves the treatment efficiency; avoids the problem that two or more process sections with the same function are arranged side by side, and reduces project investment At the same time, the filter plate is equipped with a ventilation and water passage device, so that the upward movement of the gas and the downward movement of the water are not blocked, and the aeration efficiency of the downward flow biological filter is improved, the energy utilization rate is improved, and the microbial diversity is increased. , Improve microbial metabolism, and the water quality of the equipment effluent is more stable and better.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a two-way flow aeration biological ecological pool. Background technique [0002] With the development of urbanization and the rise of comprehensive improvement of the ecological environment, land resources are becoming more and more scarce. Many sewage treatment plants are facing the problem of insufficient reserved land when expanding or upgrading bids. Even if there is enough land, the traditional sewage treatment process, It is also difficult to achieve the perfect combination of water treatment structure construction and ecological landscape. In China, under the condition of satisfying high-quality effluent, it is necessary to achieve a small footprint, economical and safe sewage treatment process and its lack. The separate construction of the structures in each process section has the problems of large footprint, complex structure, high cost and poor ecological landscape eff...
