Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figure 1, the oxidation tank for decentralized sewage treatment comprises a tank body 1.

The top of the tank body 1 is provided with a water inlet 2, the water inlet 2 of the tank body 1 is connected with a water inlet pump 19 through a water inlet pipe 18, the water inlet 2 is provided with a water inlet valve, and the water inlet pipe 18 is provided with a dosing pipe 20. The sewage to be treated is pumped into the water inlet 2 of the tank body 1 through the water inlet pump 19 and the water inlet pipe 18 and enters the tank body 1. At the same time, a catalyst may be added to the dosing tube 20 of the inlet tube 18. The catalyst can enter the tank 1 together with the sewage. The top of the tank body 1 is also provided with an exhaust hole 3, and the gas in the tank body 1 can be exhausted from the exhaust hole 3. The bottom of the tank body 1 is provided with a water outlet 5, and water treated by the oxidation tank for distributed sewage treatment is discharged from the water outlet 5.

The tank body 1 is internally provided with a filter plate 6, an aeration pipe 7, an upper screen 8, a lower screen 9 and a stirring rod 10 from top to bottom in sequence. The filter plate 6 intercepts sundries in the sewage. The gas blown out by the aeration pipe 7 pushes the sewage to continuously collide and react with the catalyst. The upper screen 8 and the lower screen 9 intercept the impurities in the sewage again. The stirring rod 10 can fully mix the sewage and the catalyst, and generates vortex, so that the decontamination effect is better.

The filter 6 slope sets up, and the impurity of the sewage under the filter 6 filtration mostly intercepts the short department of side on the filter 6, and the impurity of side eminence is then less on the filter 6. A self-sucking pump 11 is arranged between the short part of the upper side surface of the filter plate 6 and the tank body 1. Wherein, the output end of the self-priming pump 11 extends out of the tank body 1 through a connecting pipe. The self-priming pump 11 can pump out the debris on the filter 6 to the outside of the jar body 1. Therefore, most impurities on the filter plate 6 can be discharged out of the tank body 1 through the self-priming pump 11, and the guide pipe 12 is arranged at the high position of the lower side surface of the filter plate 6. The guide pipe 12 further discharges the sewage filtered by the filter plate 6 into the lower part of the tank body 1.

The aeration pipe 7 is fixed in the tank body 1 through a bracket 13 in the tank body 1. The side wall of the tank body 1 is provided with an air inlet 4, the aeration pipe 7 is communicated with the air inlet 4 on the side wall of the tank body 1, and the aeration pipe 7 is provided with a plurality of aeration ports. The gas blown out by the aeration pipe 7 pushes the sewage to continuously collide and react with the catalyst.

A filler 14 is arranged between the upper screen 8 and the lower screen 9. The filler 14 is one or more of a three-dimensional elastic filler, a rigid honeycomb filler, a fiber filler, a ceramic filler and an inclined tube filler. The filler 14 further treats the sewage in the tank 1.

One end of the stirring rod 10 extends out of the tank body 1 and is fixedly connected to the output end of the motor 15, and the other end of the stirring rod 10 is provided with a plurality of fan blades 16. The motor 15 drives the stirring rod 10 to rotate, and the fan blades 16 rotate along with the stirring rod 10, so that the sewage in the tank body 1 is driven to rotate, the sewage and the catalyst are fully mixed, eddy current is generated, and the decontamination effect is better.

The top fixed mounting in jar body 1 has guide plate 17, effectively prevents the sewage jam in the jar body 1.

When in use, sewage is pumped into the water inlet 2 from the water inlet pipe 18 through the water inlet pump 19 and finally enters the tank body 1. Sewage firstly flows to the filter plate 6 through the guide plate 17 in the tank body 1, impurities in the sewage are intercepted by the filter plate 6, and then the sewage continues to flow downwards through the guide pipe 12 at the filter plate 6. After filtering a period of time, the self-priming pump 11 is opened, and sundries on the filter plate 6 are pumped out of the tank body 1. The sewage continuously contacts the upper screen 8, the filler 14 and the lower screen 9, and the upper screen 8 and the lower screen 9 intercept the impurities in the sewage again. The filler 14 further treats the sewage in the tank body 1 of the fan blade 16. Then the motor 15 is started to drive the stirring rod 10 and rotate, so that the sewage in the tank body 1 is fully stirred, impurities are separated from water by utilizing centrifugal force, and in the separation process, the impurities are contacted with the upper sieve mesh 8, the filler 14, the lower sieve mesh 9 and the like again to be filtered again, so that the purification efficiency is improved. Finally, the purified sewage can be reused, and the utilization rate of the sewage is improved.

Above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
