As a commonly used tool in scientific research, wastewater treatment biochemical simulation experimental equipment is of great significance for studying wastewater treatment technology, optimizing treatment processes and later sewage treatment project construction.

[0003] Existing sewage treatment simulation experimental equipment usually adopts a fixed-volume treatment box design. Although it can simulate the basic process of sewage treatment, when treating different types of sewage, due to differences in sewage composition, concentration and treatment difficulty, the fixed volume ratio often cannot meet actual needs. This leads to deviations between the experimental results and the actual sewage treatment effects, and cannot provide accurate data support for the optimization of sewage treatment processes. It also affects the accuracy of the subsequent sewage treatment project construction, resulting in unnecessary waste of resources.

[0004] Therefore, the utility model proposes a sewage treatment biochemical simulation experiment equipment to solve the above problems. Utility Model Content

[0021] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] See also Figure 1 and Figure 2A biochemical simulation experiment equipment for sewage treatment comprises an anaerobic box 1, an anoxic box 2, an aerobic box 3 and a sedimentation box 4, wherein the anaerobic box 1, the anoxic box 2, the aerobic box 3 and the sedimentation box 4 are connected in sequence, the sedimentation box 4 is provided with a sludge pump 20, and the output end of the sludge pump 20 is connected with three sludge return pipes 21 respectively used for sludge to return to the anaerobic box 1, the anoxic box 2 and the aerobic box 3, the anaerobic box 1 is provided with a first partition 5 which is adapted to the internal contour of the anaerobic box 1 and can be moved and adjusted along the anaerobic box 1, the anoxic box 2 is provided with a second partition 7 which is adapted to the internal contour of the anoxic box 2 and can be moved and adjusted along the anoxic box 2, the aerobic box 3 is provided with a third partition 9 which is adapted to the internal contour of the aerobic box 3 and can be moved and adjusted along the aerobic box 3, and the first partition 5, the second partition 7 and the third partition 9 are all provided with sealing strips 23 on their sides.

[0023] It should be noted that the sealing between the partition and the wall of each processing box is achieved by the sealing strip 23, and the partition in each processing box is similar to the form of a "sealing piston".

[0024] The sewage is sequentially treated in the anaerobic tank 1, the anoxic tank 2, the aerobic tank 3 and the sedimentation tank 4 according to the process flow. According to different sewage types, the volume of the anaerobic tank 1 is changed and adjusted by moving the first baffle 5, the volume of the anoxic tank 2 is changed and adjusted by moving the second baffle 5, and the volume of the aerobic tank 3 is changed and adjusted by moving the third baffle 9, so as to determine the optimal volume ratio among the anaerobic tank 1, the anoxic tank 2 and the aerobic tank 3 when treating different types of sewage, provide a verification experimental device for the efficiency of biochemical treatment of different types of sewage, and provide design reference data for the construction size of each sewage pool in the later sewage treatment project.

[0025] Furthermore, the inner walls of the anaerobic box 1, the anoxic box 2 and the aerobic box 3 are all provided with volume scale lines 22. When the partition is moved and adjusted, the volume of the treatment box at this time can be accurately known by reading the value on the volume scale line 22 on the side of the partition.

[0026] See also Figure 1 and Figure 3 In one embodiment of the utility model, the anaerobic box 1 is provided with a first adjustment mechanism 6 for realizing movement and adjustment of the first partition 5, the anoxic box 2 is provided with a second adjustment mechanism 8 for realizing movement and adjustment of the second partition 7, and the aerobic box 3 is provided with a third adjustment mechanism 10 for realizing movement and adjustment of the third partition 9;

[0027] The first adjustment mechanism 6 includes a threaded rod 24 rotatably arranged inside the anaerobic box 1, an internally threaded barrel 25 threadably sleeved on the threaded rod 24, and a rotating rod 27 rotatably passed through one side of the anaerobic box 1. One end of the internally threaded barrel 25 away from the threaded rod 24 is fixedly connected to the first partition plate 5. A bevel gear transmission assembly 26 is provided between the rotating rod 27 and the threaded rod 24, and a hand wheel 28 is provided at one end of the rotating rod 27 located outside the anaerobic box 1. The second adjustment mechanism 8 and the third adjustment mechanism 10 have the same structure as the first adjustment mechanism 6.

[0028] In this embodiment, the rotating rod 27 is rotated by the hand wheel 28, and the threaded rod 24 is driven to rotate under the transmission action of the bevel gear transmission assembly 26. Since the threaded rod 24 and the internal threaded tube 25 are threadedly matched and the internal threaded tube 25 is fixedly connected to the first partition 5, the rotation of the threaded rod 24 drives the internal threaded tube 25 to "extend and retract", thereby driving the first partition 5 to move and adjust along the anaerobic box 1, thereby changing and adjusting the volume of the anaerobic box 1. The anoxic box 2 and the aerobic box 3 both adopt the same structure as above to achieve movement and adjustment.

[0031] Furthermore, in this embodiment, the sedimentation tank 4 is also provided with a discharge port for discharging the treated sewage.
