[0002] With the development of my country's industry and the improvement of people's quality of life, a large amount of sewage is generated in residential areas, construction sites, factories and other places. The sewage needs to be treated by sewage treatment equipment before it can be discharged. The existing sewage treatment equipment is composed of several treatment pools with different functions. The sewage passes through each treatment pool in turn and is discharged outside the sewage treatment equipment after meeting the discharge standards.

[0003] Since the pollution degree of sewage generated by each site is different, the discharge standards are also different. In theory, sewage should be treated by different treatment processes according to the pollution degree and sewage properties of each site. For sewage with high pollution degree, only after the sewage is treated in each treatment tank in turn can it meet the discharge standard; but for sewage with low pollution degree, it can meet the discharge standard by only being treated in some treatment tanks. However, in the current sewage treatment equipment, such as Figure 1 As shown, each sewage treatment tank (septic tank 100, anaerobic aerobic integrated tank 200, membrane biological reactor 300, disinfection tank 400) is usually integrated and fixed in the sewage treatment equipment. No matter what degree of pollution the sewage is, it must pass through each treatment tank completely before it can be discharged. This leads to the problem of energy waste in the existing sewage treatment equipment when treating sewage with a low degree of pollution. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] With the rapid development of my country's economy and society, the problem of sewage treatment has become increasingly prominent. Traditional sewage treatment methods generally use fixed sewage treatment facilities, such as burying huge physical sedimentation tanks underground, etc., but this treatment method has problems such as long construction period and high cost. In order to solve the problems of long construction period and high cost of traditional fixed sewage treatment facilities, mobile sewage treatment equipment has gradually emerged, integrating related facilities for sewage treatment into containers, which can realize rapid transfer of sewage treatment equipment and can be reused.

[0023] In current mobile sewage treatment equipment, each sewage treatment tank is usually integrated and fixed in the sewage treatment equipment. No matter what the pollution level of sewage is, it must pass through each treatment tank completely before it can be discharged. This leads to the problem of energy waste in existing sewage treatment equipment when treating sewage with low pollution level.

[0024] In order to solve the above technical problems, Figure 2 As shown, the utility model provides an integrated modular sewage treatment equipment, including: a box body 1, and a plurality of treatment tanks arranged in the box body 1, and two adjacent treatment tanks are detachably connected; the treatment tanks include: a septic tank 2, an anaerobic and aerobic integrated tank 3, a membrane biological reaction tank 4, and a disinfection tank 5;

[0025] The septic tank 2 is used to filter and remove suspended matter in sewage, and a grid 6 for filtering and removing the suspended matter is provided inside the septic tank.

[0026] The anaerobic-aerobic integrated pool 3 is used for primary removal of organic matter in sewage, and a partition 7 is provided inside the pool, by which the anaerobic-aerobic integrated pool 3 is divided into an anaerobic zone 8 and an aerobic zone 9; an anaerobic microbial filler bag is provided in the anaerobic zone 8, and anaerobic microorganisms are used to degrade and decompose macromolecular organic matter, heavy metals and other substances in the sewage; an aerobic microbial filler bag is provided in the aerobic zone 9, and aerobic microorganisms are used to denitrify and remove phosphorus from the sewage.

[0027] The membrane bioreactor 4 is used to deeply remove organic matter in sewage, and a membrane bioreactor 10 (MBR) is arranged inside the membrane bioreactor 10, through which the refractory organic matter in the sewage can be treated, and further nitrogen and phosphorus removal can be carried out on the basis of the treatment of the anaerobic aerobic integrated tank 3, so that the water quality can meet higher requirements. The membrane bioreactor 4 is usually used when the sewage pollution level is high and the treatment requirements are high. When the sewage pollution level is low, the membrane bioreactor 4 can be disassembled and the sewage treatment tank is not used to save energy and reduce consumption.

[0028] The disinfection tank 5 is used to disinfect sewage, and a disinfection box is arranged inside the disinfection tank 5.

[0029] The treatment tanks of the integrated modular sewage treatment equipment of the utility model are detachably connected. Different treatment tanks can be flexibly combined when using the sewage treatment equipment, so that different treatment processes can be adopted for sewage with different pollution degrees. While meeting various sewage treatment requirements, no energy waste will be generated.

[0030] Furthermore, if Figure 3 As shown, two adjacent treatment tanks are detachably connected via a hook structure 11. For the convenience of subsequent description, the treatment tank located at one end of the box body 1 is defined as a fixed tank, and the treatment tanks arranged in sequence on one side of the fixed tank are defined as an assembly tank. Those skilled in the art can understand that the fixed tank is a septic tank 2, and the assembly tank includes at least an anaerobic aerobic integrated tank 3 and a disinfection tank 5.

[0031] The tops of the fixing pool and the assembly pool are both open, a portion of the side walls of the assembly pool are provided with a hook structure 11, and another portion of the side walls are not provided with a hook knot 11; the hook structure 11 comprises: a horizontal section 111 and a vertical section 112, one end of the horizontal section 111 is connected to the edge of the side wall of the assembly pool, and the other end is connected to the vertical section 112, and the vertical section 112 is parallel to the side wall of the assembly pool.

[0032] The side wall of one assembly pool without a hook structure is inserted into the space surrounded by the hook structure 11 and the side wall of another assembly pool, so that the two assembly pools can be detachably connected. The side wall of the fixed pool is inserted into the space surrounded by the hook structure 11 and the side wall of one assembly pool, so that the fixed pool and the assembly pool can be detachably connected.

[0033] Furthermore, the sewage treatment equipment provided by the utility model is a mobile sewage treatment equipment, and the box body 1 can be installed on a large transport vehicle. According to the needs of sewage treatment, the box body 1 and each treatment pool can be transported to various places by the transport vehicle for sewage treatment. Compared with the traditional fixed sewage treatment equipment buried underground, the utility model does not require civil construction, greatly reducing the construction and installation cycle of the sewage treatment equipment, and also facilitates the maintenance of the equipment during subsequent use.

[0034] In some embodiments, the size of the box 1 can be designed according to the needs of sewage treatment. For example, if the sewage has a high degree of pollution, it is necessary to use a septic tank 2, an anaerobic aerobic integrated tank 3, a membrane biological reactor 4, and a disinfection tank 5 to treat the sewage. In this case, a large-sized box 1 that can just accommodate the septic tank 2, the anaerobic aerobic integrated tank 3, the membrane biological reactor 4, and the disinfection tank 5 is used; if the sewage has a low degree of pollution and does not need to be treated with a membrane biological reactor 4, a small-sized box 1 that can just accommodate the septic tank 2, the anaerobic aerobic integrated tank 3, and the disinfection tank 5 is used. In this way, when the integrated modular sewage treatment equipment of the utility model is moved, the size of the box 1 limits the movement of the treatment tanks, and each treatment tank is not easy to shake in the box 1.

[0035] The present invention is described in detail below with reference to the embodiments and the accompanying drawings.
