[0041] like Figures 1 to 3 As shown, an embodiment of the utility model provides an industrial wastewater classification treatment device, comprising:

[0042] Treatment tank 1, used to treat industrial wastewater;

[0044] Oxygen tank 2, oxygen tank 2 is flange-connected to air inlet pipe 3, and is used to deliver oxygen to treatment tank 1;

[0045] The water inlet pipe 5 and the water outlet pipe 6 are both fixed through the surface of the treatment tank 1 and are used to control the input of industrial waste water in the treatment tank 1 and the output of treated liquid;

[0046] The filter screen 17, the first partition plate 18, the second partition plate 19 and the activated carbon partition plate 20 are all fixedly connected to the inner wall of the treatment tank 1, and the treatment tank 1 is divided into a filter layer, a reaction layer, a sedimentation layer, an activated carbon treatment layer, and a water storage layer. The industrial wastewater enters the reaction layer through the filter screen of the filter layer. The bottom of the reaction layer is covered with activated sludge. After the activated sludge method reaction is carried out in the reaction layer, it enters the sedimentation layer for sedimentation. The liquid after sedimentation is treated by the activated carbon partition in the activated carbon treatment layer and then stored in the water storage layer.

[0047] The first U-shaped tube 9 and the second U-shaped tube 11 are both fixed through the surface of the treatment tank 1; the first valve 10 is fixedly connected to the surface of the first U-shaped tube 9 to control the liquid treated by the activated sludge method in the reaction layer to flow into the sedimentation layer of the treatment tank 1; the second valve 12 is fixedly connected to the surface of the second U-shaped tube 11 to control the liquid after sedimentation to flow into the activated carbon treatment layer of the treatment tank 1;

[0048] The first sludge discharge pipe 13 and the second sludge discharge pipe 15 are both fixed through the surface of the treatment tank 1; the third valve 14 is fixedly connected to the upper surface of the first sludge discharge pipe 13, and is used to control the discharge of excess sludge produced by the activated sludge process; the fourth valve 16 is fixedly connected to the upper surface of the second sludge discharge pipe 15, and is used to control the discharge of the sludge after precipitation;

[0049] An accelerating reaction device 8, which is arranged on the inner wall of the processing tank 1 and is used to accelerate the reaction of the reaction layer in the processing tank 1;

[0050] The fixing device 7 is arranged on the lower surface of the oxygen tank 2 and is used to fix the oxygen tank 2 to facilitate the disassembly, assembly and replacement of the oxygen tank 2.

[0051] like Figures 3 to 5 As shown, the accelerating reaction device 8 includes a rotating base 806, which is fixedly connected to the upper surface of the treatment tank 1. The upper surface of the rotating base 806 is sleeved with a rotating top cover 804. The upper surface of the rotating top cover 804 is fixedly connected to two fixed columns 801. The surface of the fixed column 801 is fixedly connected to a support rod 802. The surface of the support rod 802 is fixedly connected to a rotating column 803. The rotating column 803, the rotating base 806, the rotating top cover 804, the filter screen 17 and the upper surface of the treatment tank 1 all rotate through it. The end of the rotating column 803 away from the support rod 802 is fixedly connected to a stirring column 810. The fixed column 801 fixes the support rod 802. Rotating the fixed column 801 drives the rotating top cover 804 to rotate on the rotating base 806, so that the support rod 802 drives the rotating column 803 to rotate, and the stirring column 810 on the rotating column 803 rotates accordingly, so as to stir the activated sludge in the reaction layer and make the activated sludge fully react with the industrial wastewater and oxygen.

[0052] like Figures 3 to 5 As shown, a diverter plate 807 rotates through the surface of the rotating column 803, and the diverter plate 807 is fixedly connected to the inner wall of the treatment tank 1. The side wall of the diverter plate 807 is provided with six diverter holes 812. The diverter plate 807 diverts the industrial wastewater filtered by the filter screen 17 into the reaction layer through the diverter holes 812, so that the activated sludge in the reaction layer is evenly contacted with the industrial wastewater, thereby improving the reaction effect in the reaction layer.

[0053] like Figure 4 and Figure 5 As shown, the diverter hole 812 on the arc surface of the diverter plate 807 is fixedly connected to the diverter pipe 808, and the surface of the diverter pipe 808 is fixedly connected to four sprinkler pipes 809. The industrial wastewater flows into the diverter plate 807, flows into the diverter pipe 808 through the diverter hole 812 on the diverter plate 807, and then flows evenly to the activated sludge in the reaction layer through the sprinkler pipe 809 connected to the diverter pipe 808, so as to make the reaction more complete.

[0054] like Figure 3 and Figure 4 As shown, six fixed rods 811 are fixed through the surface of the stirring column 810. When the stirring column 810 rotates, the fixed rods 811 are driven to rotate and stir the activated sludge in the reaction layer, so that the activated sludge and industrial wastewater are evenly mixed and the reaction is more complete.

[0055] like Figure 4 and Figure 6 As shown, a rotating shaft 805 is clamped on one side of the rotating base 806 and the rotating top cover 804 that are close to each other. When the rotating top cover 804 rotates, the rotating shaft 805 can reduce the friction between the rotating top cover 804 and the rotating base 806, making the rotation more convenient.

[0056] In the embodiment of the utility model (working principle), the industrial wastewater filtered by the filter screen 17 flows evenly to the activated sludge in the reaction layer through the diverter plate 807 and the sprinkler pipe 809, and the support rod 802 is rotated to drive the fixed rod 811 to stir the activated sludge in the reaction layer, so that the activated sludge and the diverted industrial wastewater are evenly mixed to increase the reaction rate.

[0057] like Figure 1 , Figure 2 and Figure 7 As shown, the fixing device 7 includes a fixing plate 73, which is sleeved on the surface of the oxygen tank 2. Two fixing bolts 75 are threadedly connected to one side of the fixing plate 73, and the surfaces of the two fixing bolts 75 are slidably connected with fixing frames 74. When it is necessary to install and fix the oxygen tank 2, the fixing plate 73 is placed on the ground, and the oxygen tank 2 is placed therein. The fixing bolts 75 are rotated to squeeze the fixing frame 74 onto the fixing plate 73 and fix it, so that the oxygen tank 2 is fixedly installed on the ground and is not easy to tip over. When disassembling and replacing, the fixing bolts 75 are rotated to remove the fixing frame 73, and the oxygen tank 2 can be disassembled and replaced.

[0058] like Figure 7 As shown, the lower surface of the fixing plate 73 is fixedly connected with a fixing base 71, and the surface of the fixing base 71 is threadedly connected with a base bolt 72, which is threadedly connected to the ground through the base bolt 72. The base bolt 72 is rotated to squeeze the fixing base 71, so that the fixing base 71 is fixed to the ground, so that the fixing device can fix the oxygen tank 2 more firmly.

[0059] In the embodiment of the utility model, the fixed base 71 is squeezed by the base bolt 72 to fix the fixed base to the ground, and the fixing frame 74 is fixed and disassembled by rotating the fixing bolt 75, so as to achieve the disassembly and replacement of the oxygen tank 2, making the disassembly and replacement of the oxygen tank 2 easier and saving a lot of time and manpower.

[0060] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
