HSR has the following notable features: Fast speed: can significantly shorten travel time and improve travel efficiency. High safety: using advanced technology and strict safety standards to ensure safe operation. Punctual and reliable: with precise operation scheduling and high punctuality rate. Comfortable and convenient: the interior environment of the train is comfortable and the supporting facilities are complete. Large capacity: can effectively transport a large number of passengers. At present, all countries are actively developing high-speed railways, and China is a leader in high-speed railway construction and operation, with a large and advanced high-speed railway network. By the end of 2023, the mileage of high-speed railways will reach 45,000 kilometers.

[0003] As high-speed rail is booming, domestic sewage treatment is one of the problems in high-speed rail operation and maintenance. Usually, domestic sewage on high-speed rail needs to be collected and treated at the destination. High-speed rail needs to be equipped with storage containers with large floor space and a large number of exposed pipes, which is not conducive to the stable transportation of domestic sewage after collection. In addition, if domestic sewage is not treated in time, it will also produce odor problems.

[0004] In view of this, how to provide a device that occupies a small area, isolates odor, and is suitable for treating high-speed rail domestic sewage is a technical problem that people in this field urgently need to solve. Utility Model Content

[0027] In this embodiment, a mixer 400 is provided in the regulating tank 110, which can fully mix the raw sewage and the degradation agent to improve the sewage degradation effect.

[0028] In this embodiment, a generator 152 and a blower 153 are provided in the equipment room 150. The generator 152 supplies power to the mixer 400 and the blower 153. The blower 153 is connected to the aerator 180 through the aeration pipe 700. A fan and a control cabinet are also provided in the equipment room 150. Ventilation windows are provided on the sides thereof. According to actual needs, air conditioners, lighting lamps, movable stairs, etc. can also be provided.

[0029] In this embodiment, an anaerobic tank 120 and an anoxic tank 130 are formed between the regulating tank 110 and the aerobic tank 140 by a partition 200 inside the outer shell 100, and the regulating tank 110, the anaerobic tank 120, the anoxic tank 130 and the aerobic tank 140 are arranged in sequence from left to right; the water flow pipeline includes a first water flow pipeline, a second water flow pipeline and a third water flow pipeline, the regulating tank 110 and the anaerobic tank 120 are connected through the first water flow pipeline, the anaerobic tank 120 and the anoxic tank 130 are connected through the second water flow pipeline, and the anoxic tank 130 and the aerobic tank 140 are connected through the third water flow pipeline.

[0030] In this embodiment, a first return pipe 500 is also included. The first return pipe 500 is arranged in the aerobic tank 140, one end of which is connected to the sludge lifting pump, and the other end passes through the partition 200 and extends into the anoxic tank 130. The ultraviolet treatment equipment 151 has a return sludge discharge outlet and a residual sludge discharge outlet 154, and the return sludge discharge outlet is connected to the sludge lifting pump.

[0031] In this embodiment, a second return pipe 600 is also included, one end of which is disposed in the aerobic tank 140, and the other end of which passes through the anoxic tank 130, penetrates the baffle 200 and extends into the anaerobic tank 120. A water pump is disposed at one end of the second return pipe 600. Both the first return pipe 500 and the second return pipe 600 are double-end threaded steel pipes.

[0032] In this embodiment, a plurality of submersible flowmakers 170 are disposed in the anaerobic tank 120 and the aerobic tank 140 . The submersible flowmakers 170 can form a circulation in the anaerobic tank 120 and the aerobic tank 140 .

[0033] In this embodiment, the housing 100 is provided with observation holes 160 corresponding to the regulating tank 110 , the anaerobic tank 120 , the anoxic tank 130 , the aerobic tank 140 and the equipment room 150 .

[0034] The specific sewage treatment process is as follows:

[0035] High-speed rail wastewater is fed into the regulating tank 110 from the water inlet 111, the automatic feeder 300 automatically feeds degradation agents into the regulating tank 110, the mixer 400 fully mixes the wastewater and the degradation agents, and transports them to the aerobic tank 140 in sequence through the first water flow pipe, the second water flow pipe and the third water flow pipe.

[0036] The aerator 180 in the aerobic tank 140 works intermittently to aerate the sewage, thereby increasing the efficiency of sewage degradation and improving the quality of sewage. The aerated sewage is transported through the drain pipe 141 to the ultraviolet treatment device 151 for disinfection and sterilization. After the sewage is treated, it becomes usable water and is discharged through the drain port 155.

[0037] In the above process, the activated sludge in the sewage gradually settles at the bottom of the ultraviolet treatment device 151. When the aeration of the aerator 180 is intermittent and the dissolved oxygen content decreases, the sludge is partially transported to the anoxic tank 130 through the sludge lifting pump and the first return pipe 500. The sludge contains a large amount of polyphosphate bacteria. The polyphosphate bacteria can excessively gather and absorb phosphorus in the sewage under the anoxic environment of the anoxic tank 130, thereby achieving the effect of removing phosphorus from the sewage. The remaining sludge in the ultraviolet treatment device 151 loses its activity after being sterilized and disinfected by ultraviolet rays, and is discharged through the remaining sludge discharge port 154. When the aeration of the aerator 180 is intermittent and the dissolved oxygen content decreases, the second return pipe 600 returns the aerated treated reclaimed water to the anaerobic tank 120 through a water pump. The nitrogen in the original sewage enters the aerobic tank 140 in the ammonia state, and is converted into nitrate nitrogen after aeration treatment. The nitrate nitrogen returns to the anaerobic tank 120 with the reclaimed water, and can be denitrified into nitrogen gas under the anaerobic environment, thereby achieving the technical effect of sewage denitrification.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
