Background
The traditional microwave enhanced sewage treatment technology is to install a conventional sewage treatment reactor in a cavity of a microwave generator, and after microwaves are transmitted out of a waveguide tube and enter the cavity of the microwave generator, the microwaves are contacted with sewage in the sewage treatment reactor.
In the process, on one hand, microwaves are reflected by metal wall surfaces around the cavity of the microwave generator, and a large number of practical applications show that in the process of reflection, the wave crests and wave crests (or wave troughs and wave troughs) of the microwaves are overlapped at certain positions, so that the radiation intensity of the microwaves is stronger; in other positions, the wave crests and wave troughs of different microwaves are overlapped, so that the microwave radiation intensity is weaker. The external appearance form of the phenomenon is that the microwave radiation is uneven, so that the sewage in the sewage treatment reactor cannot uniformly receive the microwave radiation, and the sewage treatment effect is unstable; on the other hand, in the process of reflecting microwaves by the surrounding metal wall surfaces, part of the microwaves are reflected back to the magnetron, so that the service life of the magnetron is reduced, and the maintenance pressure is increased; finally, it should be noted that the microwave generator cavity has a certain volume, and when the sewage treatment capacity is large, the microwave generator cavity occupies a large space.

The integrated microwave conduction and sewage treatment tubular sewage treatment reactor of the invention has the preferred embodiment shown in fig. 1 to 4:
the sewage treatment device comprises a sewage inlet 1, a conventional sewage pipe 2, a perforated metal plate 3, a waveguide tube 4, a sewage pipe 5 capable of penetrating microwaves, a microwave energy output device shield 6, a magnetron 7 and a sewage outlet 8, wherein two perforated metal plates 3 are separated into a section of microwave action section M in the whole sewage flow pipeline, the microwave action section M is respectively connected with the sewage inlet 1 and the sewage outlet 8 through two perforated metal plates 3, and the magnetron 7 is arranged on any end side surface (P1, P2 or P3) of the microwave action section M.
The microwave action section M is a space surrounded by the two perforated metal plates 3 and the microwave permeable sewage pipe 5, and the length L is between 0.3 and 2M.
The specifications of the two metal plates 3 with holes are completely consistent, and the aperture ratio is between 85 and 95 percent.
The microwave-transparent sewage pipe 5 is non-microwave-absorbing and resistant to sewage corrosion.

Specific examples:
as shown in fig. 1 to 4, the sewage treatment device comprises a sewage inlet 1, a conventional sewage pipe 2, a perforated metal plate 3, a waveguide tube 4, a sewage pipe 5 capable of penetrating microwaves, a microwave energy output device shield 6, a magnetron 7 and a sewage outlet 8, wherein two perforated metal plates 3 are separated into a microwave action section M in the whole sewage flow pipeline, the microwave action section M is respectively connected with the sewage inlet 1 and the sewage outlet 8 through the two perforated metal plates 3, and the magnetron 7 is arranged on any one end side surface (P1, P2 or P3) of the microwave action section M. Specifically, the microwave action section M is a space surrounded by the two perforated metal plates 3 and the microwave-permeable sewage pipe 5, and the length L is between 0.3 and 2M. The core technology of the sewage treatment reactor is that the microwave action section M is arranged, so that the sewage can uniformly receive microwave radiation, and some chemical reactions can be completed or induced in the section, thereby improving the sewage treatment effect. Preferably, the length of the microwave action section M is 0.5M.
In the tubular sewage treatment reactor, specifically, the specifications of the two metal plates 3 with holes are completely consistent, and the aperture ratio is between 85 and 95 percent. By adopting the structure, the two metal plates 3 with holes have double functions, so that sewage can pass through with smaller resistance and can completely reflect microwaves, and the two metal plates with holes and the waveguide tube 4 can enclose a closed space for microwaves. Preferably, the aperture ratio is 90%.
In the above-mentioned tubular sewage treatment reactor, in particular, the microwave-permeable sewage pipe 5 is non-microwave-absorbing and resistant to sewage corrosion. By taking a microwave-transparent sewage pipe having this characteristic, microwaves in the sewage can be transmitted directly through the microwave-transparent sewage pipe without loss and conducted to the inner wall of the waveguide 4, so that the microwaves can be conducted forward in the sewage.
In the above-described tubular sewage treatment reactor, specifically, the outer wall of the microwave-permeable sewage pipe 5 is closely adhered to the inner wall of the waveguide 4, but is not adhered. The bonding process may use other agents to reduce the microwave-conducting effect of the waveguide inner wall.
In the above-described tubular sewage treatment reactor, specifically, the width and height of the inner cross section of the waveguide 4 are commonly determined according to sewage treatment amount, microwave wavelength and industry standard. The inner walls of the microwave-transparent sewage pipe 5 and the conventional sewage pipe 2 are identical in size and shape, and the cross sections of the microwave-transparent sewage pipe 5 and the conventional sewage pipe 2 can be round or rectangular. By adopting the structure, the design of the single tubular sewage treatment reactor can be provided with a certain flexibility.
In the above-described tubular sewage treatment reactor, in particular, the microwave energy output shroud 6 is non-absorptive to microwaves and resistant to sewage corrosion. By adopting the microwave energy output device shield with the characteristics, the microwave energy output device shield cannot be corroded by sewage, and the microwave energy output device shield cannot be influenced at the same time.
In the tubular sewage treatment reactor, specifically, any two cross-section geometric center lines of the sewage inlet 1 and any two cross-section geometric center lines of the sewage outlet 8 intersect, and the angle alpha is between 1 and 180 degrees. By adopting the structure, the tubular sewage treatment reactor can be well adapted to the limitation of sewage treatment space, and can be flexibly distributed.
In the above-mentioned tubular sewage treatment reactor, specifically, the sewage treatment reactor may function alone or may constitute a reactor group to function together according to the amount of sewage and the hydraulic retention time.

The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
