Problems solved by technology

[0003] The existing integrated container-type sewage treatment equipment is placed horizontally after completion, that is, the long side of the container is close to the ground; while the height of the short side of the standard container is 2.3 meters, if it is used for intermittent activated sludge process (SBR) sewage treatment, it restricts Effective water depth (the ideal effective aeration water depth is 4 to 5 meters), the oxygen utilization rate is not high during biochemical aeration, and the distance between the sludge sedimentation area and the clean water area is too short, resulting in sludge mixed flow when the supernatant is discharged, which affects the quality of the effluent , It is difficult to arrange funnels in the mud collection area, and the supernatant water may need power pumping due to insufficient water level, so most of them use MBR and other processes

Embodiment 1

[0035] see Figure 1-Figure 4, the vertical container-type intermittent activated sludge process sewage treatment device of this embodiment includes a frame 1 having the same external dimensions as a standard container, and this embodiment adopts a 20-foot standard container, and its external dimensions are about 6.0 × 2.3 × 2.3 meters . The frame 1 is arranged vertically, and a water treatment area suitable for the intermittent activated sludge sewage treatment process is set in it, and the water treatment area is used to regulate, aerate and settle the sewage; when used for sewage regulation , the water treatment area constitutes a regulating tank, when used for aeration of sewage, the water treatment area constitutes an aeration tank, and when used for static sedimentation of sewage, the water treatment area constitutes a sedimentation tank. The upper end of the water treatment area 2 is open, and the other sides are closed. When standing and settling, the inner cavity of...

Embodiment 2

[0049] see Figure 5 , the main difference between the embodiment and the embodiment is:

[0050] In this embodiment, an auxiliary function area 17 is also provided in the frame 1, so that the interior of the frame 1 is divided into a water treatment area 2 and an auxiliary function area 17; the auxiliary function area 17 is used for setting an electric control cabinet, a water inlet pump, Auxiliary equipment such as drainage pumps, fans, dispensing boxes, and dispensing pumps enable the auxiliary equipment to be installed before the entire device is installed on site, making it more convenient to use. It is suitable for occasions where the amount of sewage treatment is relatively small.

Abstract

The invention discloses a vertical-container-type intermittent-activated-sludge-process sewage treatment plant. A frame with the same external dimension as a standard container is used as a basic support, and a water treatment region suitable for the intermittent-activated-sludge-process (SBR) sewage treatment technique is arranged in the frame; the water treatment region integrates the functions of regulation, aeration and settling, thereby implementing functions of water intake, reaction, settling, drainage and idling in one plant; when the water level is below the available water level, the sewage treatment plant is used as a regulating tank in the water intake process; and the sewage treatment plant is used as a biochemical aeration tank in the aeration process, and is used as a settling tank in the standing and settling process. The sewage treatment plant adopts the vertically arranged container as the main body; by taking the 20-foot standard container as an example, the external dimension is about 6.0*2.3*2.3m, and the effective aeration water depth can reach 4-5m, thereby completely satisfying the SBR working conditions. The sewage treatment plant is convenient for transportation and installation, has the advantages of small occupied area, simple structure and the like, can be flexibly moved and disassembled, and is convenient for assembly and overhaul.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a vertical container type intermittent activated sludge process sewage treatment device. Background technique [0002] Ordinary sewage treatment equipment is generally installed and constructed on-site with a reinforced concrete structure, and the applicable occasion is a sewage treatment point with a fixed location for the sewage to be treated and a large amount of sewage treatment. For occasions where the location of sewage is not fixed or the amount of sewage treatment is not large, on-site civil engineering is used for construction, which has disadvantages such as high construction cost and long construction period. For this reason, there are many kinds of integrated container-type sewage treatment equipment in the prior art, for example, "a kind of container-type sewage treatment equipment" disclosed by the utility model patent with the authorized announcement number CN204325092U...
