The inner side of the bottom of the tank body 1 is provided with a titanium alloy aeration disc 11. The titanium alloy aeration disc 11 is provided with a porous air distribution disc/water distribution disc/bearing disc 12 above, which can play various roles of uniformly distributing air, uniformly distributing water, and bearing filler or catalyst, and the aperture and the number of holes of the disc body can be flexibly arranged according to the requirement. The porous air distribution plate/water distribution plate/bearing plate 12 is provided with a screen to ensure that the filler or the catalyst does not leak down. The tank wall is vertically arranged from top to bottom and is provided with a plurality of water inlets/water outlets/sampling ports 4 which can be flexibly arranged and used according to the requirement.

The charging opening 5 and the discharging opening 6 are arranged, so that the filler or the catalyst and the like can be more conveniently added and taken out without disassembling the tank body 1. Preferably, the feed inlet 5 and the discharge outlet 6 are arranged on the same vertical line, and the vertical line, the vertical line where the plurality of water inlets/water outlets/sampling ports 4 are located, and the central line of the tank body are located in the same plane. The exhaust port 3, the water inlet/water outlet/sampling port 4, the charging port 5, the discharge port 6, the water outlet/water inlet/sampling port 7, the water outlet 8 and the air inlet 9 are all provided with valves. Preferably, the material of the tank body 1 is organic glass. The ultraviolet lamp 16 is arranged inside the tank body 1, the transparent quartz protective cover is arranged outside the ultraviolet lamp 16 to protect the ultraviolet lamp 16, and the light blocking curtain is arranged outside the tank body 1 to prevent the ultraviolet lamp 16 from damaging experimenters.
The working principle of the invention is as follows:
when the device is used, gas enters the titanium alloy aeration disc 11 through the gas inlet 9, and the gas inflow is adjusted by the valve. The gas flows out from the titanium alloy aeration disc 11 through the gas inlet 9, and then is uniformly distributed in the whole tank body 1 through the porous gas distribution disc/water distribution disc/bearing disc 12 above the titanium alloy aeration disc. At this time, the porous air distribution plate/water distribution plate/bearing plate 12 has the function of uniform air distribution. The residual gas is discharged out of the tank body 1 through the gas outlet 3 so as to avoid the unorganized diffusion of harmful gas.
The invention can carry out continuous flow experiment and static experiment. The mode of upper water inlet and lower water outlet can be adopted, and the mode of upper water outlet and lower water inlet can also be adopted. When the water tank is used in an upper water inlet and lower water outlet mode, inlet water flows out of the tank body 1 through the water inlet/water outlet/sampling port 4 and the water outlet/water inlet/sampling port 7 after reaction. At the moment, the water inlet/outlet/sampling port 4 plays a role of a water inlet, the specific water inlet position can be flexibly selected according to the experimental requirement, the water outlet/inlet/sampling port 7 plays a role of a water outlet and a sampling port, and the water inlet flow and the water outlet flow are all adjusted by a valve. When the water tank is used in a mode of lower water inlet and upper water outlet, inlet water enters the tank body 1 through the water outlet/water inlet/sampling port 7, and flows out of the tank body 1 through the water inlet/water outlet/sampling port 4 after reaction. At this time, the water outlet/water inlet/sampling port 7 plays a role of a water inlet, the water inlet/water outlet/sampling port 4 plays a role of a water outlet and a sampling port, specific water outlet and sampling positions can be flexibly selected according to experimental needs, and water inlet and outlet flows are regulated by valves. At this time, the porous air distribution plate/water distribution plate/bearing plate 12 simultaneously plays a role of water distribution uniformity. When the experiment is finished and the water needs to be drained, the water outlet 8 is opened to drain the water.
When a small amount of filler or catalyst needs to be added in the experiment, the filler or catalyst can be conveniently added through the feed inlet 5 without disassembling the tank body 1, and the operation can be carried out through the discharge outlet 6 when the filler or catalyst is taken out. When a large amount of filler or catalyst needs to be added, the tank body 1 can be disassembled and assembled in sections through the flange connection disc 2, and the filler or catalyst can be filled or taken out. At this time, the porous air distribution plate/water distribution plate/bearing plate 12 functions as a bearing plate. In order to ensure that the filler or the catalyst does not leak down, a screen with corresponding specification can be additionally arranged on the porous air distribution plate/water distribution plate/bearing tray 12 according to requirements.
The invention can be used for various water treatment aeration reactions and experiments in a laboratory, and has the advantages of simple structure, convenient operation, flexible use and strong universality. The reactor is taken as a core, and other experimental devices can be flexibly accessed according to the requirement, so that the multifunctional use of the reactor is realized.
