Bi-directional flow aerated biological ecological pool

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...

Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies in the above-mentioned technologies, and propose a two-way flow aerated biological ecological pool, aiming to solve the problem that the above-mentioned biological filter has a single operation form, cannot fully utilize the effect of biological purification, and the backwash water It cannot be purified inside the filter, the equipment needs to stop working when the filter is backwashed, there are few types of microorganisms in the equipment, and the energy utilization rate is low, etc.
