The fan 23 runs to extract the water vapor and volatile gases and transport them outward through the air pipe 22. When the water vapor and volatile gases pass through the middle of the air pipe 22, they are cooled by the sewage in the separation chamber of the separation box 16 in the cold zone. After cooling, the water vapor condenses into water, so that the mixture of water, water vapor and volatile gas is input into the gas-liquid separator 25, so that the water gathers at the lower part of the gas-liquid separator 25 and is discharged through the water outlet pipe 26, and the water vapor and volatile gas gather at the upper part of the gas-liquid separator 25 and are discharged through the gas outlet pipe 27. The gas outlet pipe 27 inputs the water vapor and volatile gas into multiple catalytic tubes 28. When the volatile gas flows in the multiple catalytic tubes 28, it is irradiated by the ultraviolet rays emitted by the multiple ultraviolet lamps 30, and cooperates with the multiple catalyst mesh plates 29 to catalytically oxidize and decompose the volatile gas.

[0036] The main functions achieved by the present invention are:

[0037] 1. It can carry out biological treatment and high-temperature disinfection and sterilization of sewage, reduce the risk of sewage infecting poultry and reduce poultry illness;

[0038] 2. Use solar heating system to reduce energy consumption of sterilization treatment;

[0039] 3. Use the volute channel to separate the sewage into solid and liquid, which is convenient for the subsequent treatment of solid impurities;

[0040] 4. It can carry out efficient catalytic oxidation treatment of volatile gases.

[0041] A poultry breeding wastewater treatment device of the present invention has common mechanical installation methods, connection methods or setting methods, which can be implemented as long as they can achieve their beneficial effects; a treatment pool 1, a partition 2, a solar thermal pipe group 5, a high-temperature heat dissipation pipe 9, a low-temperature heat dissipation pipe 10, a filler layer 13, a component detector 15, a volute guide plate 19, a filter cartridge 20, an air collecting hood 21, a fan 23, a fin 24, a gas-liquid separator 25, a catalyst mesh plate 29, an ultraviolet lamp tube 30, and a slag receiving pool 31 of a poultry breeding wastewater treatment device of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
