[0029] Furthermore, the mixing mechanism 2 includes a motor 201, a rotating shaft 202, stirring blades 203 and a material shifting rod 204. The motor 201 is fixedly installed in the middle of the top of the coagulation tank 3, and the rotating shaft 202 is rotatably installed inside the coagulation tank 3. The output end of the motor 201 is fixedly connected to the top of the rotating shaft 202. There are a plurality of stirring blades 203, which are arranged in a circle on the shaft body of the rotating shaft 202. The material shifting rod 204 is fixedly installed on the bottom shaft body of the rotating shaft 202. A plurality of through holes 2031 are opened at one end of each stirring blade 203 away from the rotating shaft 202, and a roller 2032 is rotatably connected to the lower end of each stirring blade 203.

[0030] In the specific setting, a plurality of groups of stirring blades 203 are arranged on the shaft body of the rotating shaft 202 from top to bottom, and each group of stirring blades 203 is arranged in a circle on the shaft body of the rotating shaft 202. When working, the laboratory virus sewage and the coagulant are respectively introduced into the coagulation tank 3 through the water inlet pipe 301 and the feeding funnel 6, and the rotating shaft 202 and the plurality of stirring blades 203 are driven to rotate by starting the motor 201. The coagulant and the sewage are mixed by the stirring blades 203 to form flocs.

When the roller 2032 passes the movable plate 305, the spring 304 rebounds, driving the movable plate 305 and the blocking block 306 to move upward, so that the discharge port is opened, facilitating the subsequent discharge of the flocs.

[0033] Furthermore, the aeration mechanism 4 includes an aeration tank 401, an aeration pipe 402 and an air pump 403.

[0034] In the present application, the liquid after coagulation treatment is passed into the aeration tank 401 through the water pump 9, and oxygen is added into the aeration tank 401 through the air pump 403 to promote the oxidation and decomposition of organic matter in the sewage and remove organic pollutants in the sewage.

[0035] Furthermore, the disinfection mechanism 8 includes a disinfection tank 801, a first baffle 802, a second baffle 803 and an ultraviolet lamp tube 804.

The upper end of the middle second baffle 803 is fixedly connected to the lower surface of the first baffle 802, and the bottoms of the two second baffles 803 on both sides are fixedly connected to the bottom inner wall of the disinfection tank 801. The ultraviolet lamp tube 804 is overlapped on the three second baffles 803.

[0036] In the specific setting, the sewage after coagulation and aeration treatment is passed into the disinfection tank 801, and flows to the left from the right side of the first baffle 802 in sequence. By setting three second baffles 803, the time of sewage in the disinfection tank 801 can be extended, thereby extending the ultraviolet irradiation time and improving the disinfection and sterilization effect.

[0037] Through the above technical scheme, laboratory viral wastewater can be treated with multi-stage coagulation, aeration and disinfection, thereby improving the treatment effect of wastewater and protecting the safety of the ecological environment.

When the roller 2032 rotates to the movable plate 305, it rolls along the inclined surface of the movable plate 305, pressing the movable plate 305 downward, and at the same time drives the guide rod 303 and The block 306 is pressed downward, and the spring 304 contracts. The block 306 pushes the flocs in the discharge port downward to avoid blocking the discharge port. The liquid after coagulation treatment is passed into the aeration tank 401 through the water pump 9, and oxygen is added to the aeration tank 401 through the air pump 403 to promote the oxidation and decomposition of organic matter in the sewage and remove organic pollutants in the sewage. The sewage after coagulation and aeration treatment is passed into the disinfection tank 801 and flows to the left from the right side of the first baffle 802 in sequence, thereby extending the ultraviolet irradiation time and improving the disinfection and sterilization effect. The treated sewage flows out from the outlet pipe 10.

[0040] To sum up: this kind of integrated laboratory virus sewage treatment equipment, by setting a mixing mechanism 2, an aeration mechanism 4 and a disinfection mechanism 8 to coagulate, aerate and disinfect the laboratory sewage in turn, can effectively remove large molecular pollutants, organic pollutants and viruses and bacteria in the sewage, thereby protecting the safety of the ecological environment; by setting a plurality of through holes 2031 on the stirring blade 203, it can help the flow of sewage and coagulant and improve the mixing degree of sewage and coagulant; by setting a roller 2032 intermittently connected with the movable plate 305, the block 306 can be pushed up and down to facilitate pushing the flocs in the discharge port downward to avoid clogging the discharge port; by setting three second baffles 803, the time of sewage in the disinfection tank 801 can be extended, thereby extending the ultraviolet irradiation time and improving the disinfection and sterilization effect.
