Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a household high-efficiency integrated reaction tank. Background Art

[0002] Rural sewage mainly consists of two parts: black water and grey water generated by residents' lives. Rural domestic sewage is mainly the sewage generated during the lives of villagers, and the water consumption is directly affected by factors such as living conditions, living habits, and solar terms, such as feces, showers, household kitchen waste, and washing sewage. With the rapid economic development, the pollution of rural sewage has become extremely urgent, and it is necessary to strengthen the treatment of rural domestic sewage. China has a vast territory, and the village layouts and terrain environments in different places are different. For some mountainous areas, areas where excavation construction is not possible, areas with many river channels and forks that are not suitable for large pipeline collection, and areas where villagers are very scattered, many units have developed different small-scale decentralized devices, but they all face problems such as high cost, large floor area, and cumbersome later maintenance and management.

[0003] The utility model patent with the publication number CN 212174748 U discloses a micro domestic sewage treatment device, which includes a tank body, as well as an inlet and an outlet arranged on the tank body. The inlet is connected to an inlet pipe, and the outlet is connected to an outlet pipe; a plurality of partition plates are vertically arranged in the tank body to divide the tank body into several treatment areas. All treatment areas are, in the order of water flow direction, a pre-reaction area, a first anoxic area, a first aerobic area, a second anoxic area, a second aerobic area, and a sedimentation area. The outlet end of the inlet pipe is arranged at the top of the pre-reaction area, and the outlet is arranged on the upper side wall of the tank body corresponding to the sedimentation area; flow-through openings are arranged on the partition plates corresponding to adjacent two treatment areas of all treatment areas; aeration devices are arranged at the bottoms of the first aerobic area and the second aerobic area, and the aeration devices are connected to an aeration pump. Biological fillers are arranged in the upper and middle parts of the first aerobic area and the second aerobic area; a reflux device is also provided to reflux the mixed liquid at the bottom of the sedimentation area to the first anoxic area.

[0004] The above solution sets an anoxic area for denitrification, but for the sewage treatment of single rural households, the pertinence is not strong; and Figure 1 It can be seen that its reaction area is arranged in a circular ring shape, the water flow direction is circular, the floor area is large, which is not conducive to the setting of single rural households; and its internal structure is complex, the comprehensive cost is high, and it is not convenient for mass production. Content of the Utility Model

[0005] In view of this, in order to solve the above problems, the present utility model proposes a household high-efficiency integrated reaction tank, which integrates a sedimentation tank 4, an aerobic tank 5 and a sedimentation tank 6 into one device. It can remove COD and ammonia nitrogen in household sewage without an anoxic zone, with strong pertinence. The aerobic tank 5 and the sedimentation tank 6 are in a vertical flow series mode, occupying a small area. At the same time, the internal structure of the device is simple, which is more convenient for batch modular production. It can be one for each household, reducing the coordination of contradictions during construction.

The sewage treated by the grille basket 42 falls along the guide cylinder 41 to the first baffle 7.

[0008] Further, the biological filler 51 is filled between the first baffle 7 and the second baffle 8. When the water body passes through the biological filler 51, it absorbs COD and ammonia nitrogen in the water body, resulting in a high treatment load and a small amount of sludge.

[0009] Further, a number of second openings are provided on the second baffle 8 to further block the scum after reacting with the biological filler 51 at the biological filler 51, so that the reacted water body can pass through the second openings and enter the sedimentation tank 6.

[0010] Further, an aeration system 9 is provided in the aerobic tank 5 and the sedimentation tank 6 for aerating the aerobic tank 5.

[0011] Further, the aeration system 9 includes a first aeration pipe 91 and a second aeration pipe 92. The first aeration pipe 91 is arranged in the aerobic tank 5, and sealing heads 93 are provided at both ends of the first aeration pipe 91. The second aeration pipe 92 is vertically arranged. One end of the second aeration pipe 92 is connected to the first aeration pipe, and the other end extends towards the sedimentation tank 6 and is connected to the air outlet of an external aeration pump.

[0012] Further, the aerobic tank 5 adopts a fixed bed mode to avoid the biological film on the filler being washed away by aeration, improve the treatment efficiency, and reduce the sludge volume.
