[0016] In this embodiment, the spray device 103 is a spiral nozzle, so that the sprayed wastewater is in the form of water mist, thereby increasing the contact area between the wastewater and the air.

[0017] In this embodiment, the anti-corrosion filler 104 is a plastic with a polyhedral structure, which further increases the contact area between wastewater and air.

[0018] In this embodiment, a power cord 2 connected to an external power source is provided on the device body, and the output end of the power cord 2 is respectively connected to the input end of the fan 106 and the input end of the water pump 107, and provides electric energy to the fan 106 and the water pump 107 after the power is turned on.

[0019] In this embodiment, the water inlet of the water pump 107 is connected to an external pipeline, and a valve is provided between the water pump 107 and the external pipeline. When the valve is opened, waste water is transported to the tower body 1 through the transport pipeline 108 .

[0020] In this embodiment, the lower end surface of the tower body 1 is provided with a tower body outlet 109 for discharging the fallen and collected wastewater to an external water reservoir. The treated wastewater may be collected at the bottom of the tower body 1, so the treated wastewater is discharged to the external water reservoir through the tower body outlet 109.

[0021] In this embodiment, the number of the filling brackets 105 is not less than three, and can be added or reduced according to actual conditions. For example, the larger the tower body 1, the more anti-corrosion fillers 104 are required, and therefore the more filling brackets 105 are required, and vice versa.

[0022] In this embodiment, the principle of the utility model is that the ammonium ions in the wastewater are converted into free ammonia under alkaline conditions, thereby separating them from the wastewater. The efficiency of free ammonia (i.e., ammonia gas) directly overflowing from the wastewater is very low, so the fan 106 is selected to supply air, and the free ammonia in the wastewater is quickly separated from the wastewater by the action of external force. A spiral nozzle is used inside the tower body 1, and the wastewater pressurized by the water pump 107 is sprayed out from the nozzle. The wastewater is in a mist and becomes water droplets with very small molecular weight, which directly increases the contact area between the wastewater and the air, thereby enhancing the treatment effect. At the same time, an anti-corrosion filler 104 is used in the tower. The anti-corrosion filler 104 is a plastic with a polyhedral structure, which can increase the contact area between the wastewater and the air again, thereby enhancing the treatment effect again.

[0023] In this embodiment, the water pump 107 is a booster pump device, such as a CHLF / CDMF fully automatic variable frequency constant pressure water pump, a CWS-VI integrated constant pressure variable frequency water pump, etc.

[0024] In this embodiment, the fan 106 is a common air supply equipment, such as a SHT-300mm12 portable air supply fan, a 4-72-C medium-pressure industrial fan, etc.

[0025] In this embodiment, the control circuit of the utility model is a common circuit in the circuit field. The utility model is connected to an external power supply or a built-in battery to provide power for the device. Technicians in the relevant technical field can implement it and will not be described in detail here.

[0026] During the specific implementation of the utility model: during use, wastewater is transported to the tower body 1 through the transport pipe 108. During the wastewater transportation process, the water pump 107 pressurizes the wastewater so that the wastewater sprayed from the spiral nozzle is in the form of water mist, which becomes water droplets with very small molecular weight, directly increasing the contact area between the wastewater and the air. The water mist falls on the anti-corrosion filler 104. The anti-corrosion filler 104 is a plastic with a polyhedral structure, which can further increase the contact area between the wastewater and the air. At the same time, the fan 106 supplies air to the tower body 1 through the air supply port 102, and the free ammonia in the wastewater is quickly separated from the wastewater through the action of external force. Finally, the wastewater collected at the bottom of the tower body 1 is discharged to the external water storage tank through the tower body water outlet 109.
