The connecting pipe 128 is fixedly embedded in the lower end of the sewage tank 1. Multiple aeration discs 129 are provided on the outer surface of the connecting pipe 128. The aeration discs 129 convert the air into fine bubbles. During the aeration process, isooctane in the sewage evaporates and forms gaseous pollution. The vacuum pump 115 is connected to the transfer pipe 111 via the extension pipe 114. Therefore, the vacuum pump 115 draws the gaseous isooctane into the filter box 117 through multiple U-shaped pipes 110 and the transfer pipe 111. One-way valve 112 is provided at one end of the transfer pipe 111 to prevent gas backflow. The extension pipe 114 and the transfer pipe 111 are connected by two sealing sleeves 113.

A one-way valve 112 is provided at one end; a mounting bracket 116 is fixedly installed on the side of the sewage tank 1 away from the blower 103, a filter box 117 is fixedly installed on the top of the mounting bracket 116, an exhaust pipe 118 is provided on the top of the filter box 117, a through groove 119 is opened on one side of the filter box 117, and a placement box 120 is movably embedded inside the through groove 119; a plurality of through holes 122 are opened on the side of the placement box 120 near the sealing cover 101, and a sealing ring 121 is provided on one side of the placement box 120; an air pump 115 is provided at the lower end of the filter box 117 near the sealing cover 101, an extension pipe 114 is fixedly installed at the input end of the air pump 115, and sealing sleeves 113 are fixedly installed on the outer surfaces of the opposite sides of the extension pipe 114 and the transmission pipe 111, and magnets 134 are provided on the opposite sides of the two sealing sleeves 113.

[0039] In this embodiment, a placement box 120 is movably embedded inside the filter box 117. The placement box 120 is filled with activated carbon. Gas isooctane enters the placement box 120 through multiple through holes 122. The activated carbon inside has a strong adsorption capacity and can adsorb the gaseous isooctane. The filtered and purified gas is discharged through the exhaust pipe 118. The placement box 120 can be removed from the filter box 117, and the activated carbon inside can be replaced periodically. A sealing ring 121 is fixedly installed on one side of the placement box 120 to prevent gas isooctane from entering. In case of leakage, after the sewage treatment is completed, pull the limit pin 106 out of the limit hole 133. The sealing cover 101 can be opened by the handle 109. When the sealing cover 101 is rotated, the two sealing sleeves 113 are opened, so that the extension pipe 114 and the transmission pipe 111 are no longer connected. The filter screen plate 124 can be taken out from the inside of the sewage tank 1 by the connecting rod 126. The filter screen plate 124 can block the floating objects that are dispersed by the aeration treatment. The floating objects settle on the filter screen plate 124 to prevent them from adhering to the aeration disc 129 and affecting the use of the aeration disc 129.

[0040] Working principle: During use, the sealed cover 101 is closed, and sewage is introduced into the sewage tank 1 through the inlet pipe 131. Sealing the sewage tank 1 prevents isooctane from directly evaporating during aeration and polluting the air. The blower 103 is turned on to transmit air through the air supply pipe 104 to the interior of the connecting pipe 128. The connecting pipe 128 is fixedly embedded in the lower end of the sewage tank 1. Multiple aeration discs 129 are provided on the outer surface of the connecting pipe 128. The aeration discs 129 convert the air into fine bubbles. During the aeration process, isooctane in the sewage evaporates and forms a gaseous state. The contaminant is extracted by a vacuum pump 115 connected to a transfer pipe 111 via an extension pipe 114. The vacuum pump 115 draws the gaseous isooctane through multiple U-shaped pipes 110 and the transfer pipe 111 into the filter box 117. A one-way valve 112 is installed at one end of the transfer pipe 111 to prevent gas backflow. The extension pipe 114 and the transfer pipe 111 are connected by two sealing sleeves 113. Magnets 134 are installed on the opposite sides of the two sealing sleeves 113. The attraction between the magnets 134 allows the extension pipe 114 and the transfer pipe 111 to connect. A placement box 120 is movably embedded inside the filter box 117. The placement box 120 is filled with activated carbon. Gas isooctane enters the placement box 120 through multiple through-holes 122. The activated carbon inside has a strong adsorption capacity and can adsorb the gaseous isooctane. The filtered and purified gas is discharged through the exhaust pipe 118. The placement box 120 can be removed from the filter box 117, allowing for periodic replacement of the activated carbon. A sealing ring 121 is fixedly installed on one side of the placement box 120 to prevent gaseous isooctane leakage. After the sewage treatment is completed, pull the limit pin 106 out of the limit hole 133. The sealing cover 101 can be opened by the handle 109. When the sealing cover 101 is rotated, the two sealing sleeves 113 are opened, so that the extension pipe 114 and the transmission pipe 111 are no longer connected. The filter screen plate 124 can be taken out from the inside of the sewage tank 1 by the connecting rod 126. The filter screen plate 124 can block the floating objects that are dispersed by the aeration treatment. The floating objects settle on the filter screen plate 124 to prevent them from adhering to the aeration disc 129 and affecting the use of the aeration disc 129.
