The functional modules added in the embodiment can be prefabricated in factories, so that the system has more functions and meets the customization requirements of customers.

It is worth to be noted that the principle of sewage treatment by each water treatment module is as follows:

(1) The anaerobic biological treatment in the anaerobic treatment module 11 is a process of forming nutritional conditions and environmental conditions required by anaerobic microorganisms under anaerobic conditions, decomposing organic matters in wastewater by using the anaerobic microorganisms and producing methane and carbon dioxide; the anaerobic treatment module 11 refers to a reaction tank having no dissolved Oxygen nor nitrate, having a low COD (Chemical Oxygen Demand Chemical Oxygen, which indicates the amount of Oxygen required to oxidize organic substances in water with Chemical oxidants), and the anaerobic biological treatment process may be divided into four stages: hydrolysis stage, acidification stage, acetogenesis stage and methanogenesis stage.

(2) The anoxic treatment module 12 is a reaction tank with a small amount of dissolved oxygen and nitrate, and mainly degrades organic matters in the wastewater by using facultative microorganisms and a biological membrane. Specifically, dissolved oxygen in the anoxic treatment module 12 needs to be controlled to be 0.3-0.8mg/l, so that the denitrifying bacteria can be ensured to utilize nitrogen in the nitrate as an electron acceptor under the condition of extremely low dissolved oxygen concentration, and the nitrate is reduced into nitrogen, thereby realizing the denitrification process of the sewage. Meanwhile, denitrification can provide partial alkalinity, so that favorable conditions are provided for the subsequent nitrification reaction of the aerobic treatment module 13 (nitrite and nitrate are generated and can flow back to the anoxic treatment module 12 to be treated), the main function of the system is to remove nitrate nitrogen through denitrification reaction, and the system has low BOD (biochemical oxygen demand, which is the amount of dissolved oxygen consumed by biochemical processes performed by microorganisms for decomposing certain oxidizable organic matters in water under specific conditions).

(3) The aerobic treatment module 13 is used for aerobic respiration of the activated sludge to further decompose organic matters into inorganic matters. The aerobic treatment module 13 maintains the dissolved oxygen content in the water at about 4mg/l by measures such as aeration and the like, and is suitable for the growth and propagation of aerobic microorganisms therein, thereby treating pollutants in the water. Specifically, under the aerobic condition, the microorganisms in the activated sludge use one part of organic matters in the sewage to synthesize new cells, and decompose and metabolize the other part of organic matters to obtain energy required by cell synthesis, and the final product is CO ₂ And H ₂ O and the like; organic nitrogen and free ammonia nitrogen in the sewage are gradually converted into nitrite and nitrate under the condition that dissolved oxygen is sufficient while organic matters are oxidized. Therefore, the main function of the aerobic treatment module 13 is to degrade organic matters and nitrify ammonia nitrogen.

Therefore, different oxygen environments can be provided with different microorganism groups, and the microorganisms can change the behavior when the environment is changed, thereby achieving the aim of removing different pollutants.

(4) The main functions of the precipitation treatment module 14 are as follows: 1. the sinkable objects or the floating objects are removed, and the load of subsequent treatment facilities is reduced; 2. fine solids are flocculated into larger particles, so that the solid-liquid separation effect is enhanced; 3. has certain adsorption and removal effects on colloidal substances; 4. the device can play a role of a regulating tank to a certain extent and has a certain homogenization effect on water quality; 5. in addition, an iron-containing coagulant can be added in front of the primary sedimentation tank to enhance the dephosphorization effect.

(5) Two layers of biological treatment filter screens 15a formed by broken stones or plastic product fillers can be arranged in the biological filtration treatment module 15, when sewage is settled, the sewage is in clearance contact with microbial films growing on the surfaces of the biological treatment filter screens 15a, so that the sewage is purified, and after purification, the sewage is discharged to the clear water storage module 16 from the bottom of a partition plate 18 between the biological filtration treatment module 15 and the clear water storage module 16.

(6) Ultraviolet rays can also be provided in the clean water storage module 16 for final sterilization and disinfection. Because a large amount of escherichia coli and the like are generated in the biochemical degradation process, the escherichia coli and the like can be sterilized by ultraviolet rays and then discharged from the water outlet pipe 102. In addition, bleaching powder is added for sterilization and disinfection, and the bleaching powder reacts with water to generate hypochlorous acid, so that the sterilizing and disinfecting effects are achieved.

It should be noted that, in actual operation, according to the requirement of water treatment, all of the above treatment modules may be arranged, or some of them may be arranged according to the requirement, which is not limited herein.

Referring to fig. 6, in some embodiments, the gas distribution manifold 100 is perpendicular to the length direction of the container 10, and the communicating pipes 110 communicate with the surface of the pipe body of the gas distribution manifold 100. By adopting the arrangement mode of the embodiment, the gas distribution header pipe 100 is perpendicular to the length direction of the container 10, the space in the length direction can be saved, the space in the width direction of the container 10 is not occupied more, and the intensive degree is improved.

The first pipe frame 210 is laid on the bottom plate, and the gas discharged from the plurality of gas holes has a large area and is homogenized and comprehensive; the air holes face the bottom plate, the sprayed air firstly touches the bottom plate and then turns back to the space, and because the included angle between the axis of the air holes and the vertical direction is 40-50 degrees and faces the outer side of the first pipe frame 210, the turned-back air flow touches the inner wall of the space and then turns back again, and the water body in the space can be fully stirred by multiple times of turning back, so that the sewage is fully homogenized; because the air hole faces one side of the bottom plate, the blockage caused by the covering of the sewage settled in the sewage can be avoided.

Referring to fig. 6, in some embodiments, the stirring assembly 200 at the bottom of the aerobic treatment module 13 comprises a second pipe frame 220, a plurality of air wheels 221 are distributed on the second pipe frame 220, and an exhaust direction of the air wheels 221 faces away from the bottom plate. The dissolved oxygen content in the aerobic treatment module 13 needs to be about 4mg/l, so a large air disc 221 needs to be arranged to realize the transportation of a large amount of oxygen; the large air plate 221 also further enhances the effect of homogenizing the sewage.
