Description

Miniaturized good oxygen aeration tank

Technical Field

The utility model belongs to the technical field of sewage treatment, especially a miniaturized good oxygen aeration tank.

Background

The aerobic aeration tank is a functional component commonly used in a sewage treatment system, and is mainly used for disinfecting, oxidizing and reducing the level of anaerobic pathogens of sewage.

The structure of the existing aerobic aeration tank generally comprises a box-type or box-type sealed cavity, wherein a water inlet pipe and a water outlet pipe are respectively arranged on two sides of the cavity, and an aeration pipe is arranged in the cavity for aeration. The aerobic aeration tank can basically realize the aeration function, but in the actual use process, the structure of the aerobic aeration tank can realize better aeration effect only by matching with other structural designs and functional areas.

First, a solid-liquid separation facility or a settling facility should be installed at the front end of the aeration tank to separate the liquid from the excrements in the excrement, and then to aerate the liquid. Secondly, even if solid-liquid separation or sedimentation work is performed, a part of the solid and the residue are mixed in the liquid. During the aeration process, the solids can be quickly disturbed to be suspended in the liquid to form suspended matters under the action of air flow, so that after the aeration is finished, the liquid can be pumped out after the solids are kept for a long time, and the residual solids, residues and the liquid are prevented from being discharged together. Thirdly, the arrangement of the water outlet pipes needs to be designed, and the arrangement modes of the water outlet pipes commonly used at present can be divided into two types according to the existence of external power. Such as passive drainage using head, top in and bottom out, and active drainage using pump extraction. In the passive drainage process, because the water flow can generate surging in the horizontal direction, the settled solids and residues at the bottom of the aeration tank can be disturbed, and a large amount of solids can be caused to flow outwards particularly in the later stage of drainage. In the active drainage process, the passive drainage process is better, but in the process of pumping from bottom to top by the pump, the solid and residue near the water inlet side of the water outlet pipe can be caused to rush out, and if the power of the pump is too high, the liquid in the whole aeration tank can also be caused to rush.

Therefore, although the principle of the aeration tank is simple, a plurality of containers, components and equipment are required to be matched in the actual process to achieve the ideal effect. Such a design would undoubtedly raise the cost and maintenance requirements of the required equipment and also increase the required floor space. Therefore, the method is only suitable for matching with large factories such as sewage or excrement treatment plants. However, in the actual application process, with the development of energy conservation, emission reduction and resource utilization consciousness, more and more community individuals also need the small aeration equipment. For example, a water storage device for collecting rain and snow in a community, or a wastewater treatment device matched with a septic system in a rural area and a public toilet, and the like.

Therefore, aiming at the defects, the aeration tank is improved and designed based on the structure of the aeration tank, and the functions of the aeration tank are enriched on the premise of not increasing external equipment and occupied area, so that the aeration tank is suitable for some individuals to use and carry out some water treatment processes with lower standards.
