Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
The invention will be further described with reference to the accompanying drawings and specific embodiments:
example one
Referring to fig. 1, the deodorizing device for treating the odor overflowing from the closed space of the sewage treatment plant comprises a cylinder body 1 matched with a well head, a filler bearing layer 2 is arranged at the bottom of the cylinder body 1, a deodorizing filler layer 3 is arranged on the filler bearing layer 2, activated carbon is arranged in the deodorizing filler layer 3, a well lid 4 is arranged at the top of the cylinder body 1, and the cylinder body 1 and the well lid are fixedly connected through a buckle 5.
In this embodiment, the barrel 1 and the filler bearing layer 2 are both cylindrical structures, and the filler bearing layer 2 is uniformly provided with a plurality of air holes. In addition, a cavity is arranged between the deodorization packing layer 3 and the well cover 4.
According to the principle of biological deodorization, odor is dispersed upwards and simultaneously decomposed into CO through the porous active carbon deodorization filter material layer filled with active microorganisms by utilizing the adsorption, absorption and degradation functions of microbial cells on malodorous substances and the characteristics of small cells, large surface area, strong adsorbability and various metabolic types of the microorganisms after being adsorbed 2 、H 2 O、H 2 SO 4 、HNO 3 And simple inorganic matters, thereby achieving the purposes of deodorizing, reducing the odor concentration in a closed space and relieving the odor accumulation.
