[0042] The optimal working principle in the utility model is as follows

[0043] When in use, sewage enters the box body 21 through the water inlet pipe 22, and then passes through the solid-liquid separation plate 23 set in the box body 21. The solid and the liquid are separated by the solid-liquid separation plate 23. The solid is blocked by the solid-liquid separation plate 23 and then falls downward onto the separation conveyor belt 67. A small amount of liquid drips into the separation box 28 through the separation hole 30, and then is discharged into the main drain pipe 32 through the auxiliary drain pipe 31, and enters the sewage pool 3 through the main drain pipe 32. When it is necessary to clean the solid that falls on the separation conveyor belt 67, the handle (not shown in the figure) or the output shaft of the motor (not shown in the figure) can be inserted into the positioning groove 71a of the rotating shaft 71, and the separation conveyor belt 67 can be moved by driving the rotating shaft 71, so that the solid on the separation conveyor belt 67 is conveyed to the collection unit 80;

[0044] In addition, the liquid falling into the box body 21 through the separation port 26 enters the main drain pipe 32 through the water outlet 27, and then enters the sewage pool 3 through the main drain pipe 32. The toxic and harmful gases enter the extraction and purification unit 8 through the air duct 4. The purified gas discharged by the extraction and purification unit 8 is discharged into the air through the exhaust pipe 9. As a preferred method, the following specific steps may also be included:

[0045] The environmental protection project safety monitoring intelligent disposal interconnection host (monitoring interconnection host 2) is powered on. When the detection value of the flammable, explosive, toxic and harmful gas monitor (gas monitor 1) reaches the warning value of the monitoring interconnection host 2, the Internet computer 11 and the Internet mobile phone 12 can view the concentration change data and charts in real time, and the explosion-proof centrifugal fan 7 is started. The inlet and outlet of the explosion-proof centrifugal fan 7 are connected to the equipment by a flame-retardant flexible soft connection. The flammable, explosive, toxic and harmful gases such as combustible gases in the environmental protection project sewage and wastewater pool (sewage pool 3) pass through the air duct 4 and enter the integrated extraction and purification equipment (extraction and purification unit 8). The air duct 4 is connected to the integrated extraction and purification equipment through a flange. The flammable, explosive, toxic and harmful gases are preliminarily filtered by the filter cotton 5, and are adsorbed, reduced and purified by the waterproof honeycomb activated carbon layer 6 (other environmental protection purification materials can also be provided). The discharged purified gas is discharged into the air through the exhaust pipe 9. The integrated extraction and purification equipment is flange-connected to the exhaust pipe 9. A rain cap 10 is provided on the top of the exhaust pipe 9 to prevent rainwater and other foreign matter from entering the extraction and purification system.

[0046] When the concentration of flammable, explosive, toxic and harmful gases (methane, hydrogen sulfide, etc.) accumulated in the sewage treatment environment of the utility model reaches the set warning danger threshold, the big data function of the Internet is used to realize the Internet computer 11 and the Internet mobile phone 12 to view the gas concentration changes and early warning disposal response in real time, and the flammable, explosive, toxic and harmful gases in the relatively limited space of the sewage treatment facility structure can be timely extracted and discharged into the atmosphere after environmental purification, solving the flammable, explosive, toxic and harmful gas danger sources and environmental purification problems in the sewage treatment facility structure, and further eliminating the hidden dangers of production safety risks. It is conducive to the enhancement of the digitalization, informatization, remote controllability and other functions of daily production and operation management.

[0047] By utilizing the digital and information features of the Internet, mobile phones and computers can be interconnected through app software and website username and password login, and the concentration of flammable, explosive, toxic and harmful gases can be checked in real time, and emergency response and treatment measures can be initiated in a timely manner. At the same time, the explosion-proof centrifugal fan can be automatically linked to force extraction and environmental purification by setting the warning value of the concentration of such gases.

[0048] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
