[0024] In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0025] Secondly, the "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. In different places in this specification, "in one embodiment" does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

[0026] Embodiment 1

[0027] Reference Figure 1 and Figure 2 , the first embodiment of the present application provides a water treatment device which can improve the gas content rate inside the water treatment device, comprising a ditch body 100, an aeration member 200.

[0028] Specifically, the ditch body 100 comprises an outer wall 101 and a center guide wall 102, the outer wall 101 is arranged outside the ditch body 100, and the center guide wall 102 is arranged inside the ditch body 100, and the center guide wall 102 divides the ditch body 100 into left and right sides.

[0029] The aeration member 200 includes a rotating shaft 201 and an aeration rotating brush 202, the two ends of the rotating shaft 201 are matched with the inner walls of the center guide wall 102 and the outer side wall 101 respectively, and the aeration rotating brush 202 is fixedly arranged on the rotating shaft 201. The aeration member 200 also includes a motor, the motor drives the rotating shaft 201 to rotate when working, and in turn drives the aeration rotating brush 202 to rotate, when the sewage flows to the vicinity of the aeration member 200, the aeration rotating brush 202 will rotate to stir the water body, and oxygen is delivered into the water, so that the sewage is fully contacted with the oxygen, and the biological treatment effect of the sewage is promoted.

[0030] Further, the groove body 100 is annular, and the entire groove body 100 forms a circulating flow aeration ditch.

[0031] The aeration member 200 is fixedly arranged above the groove body 100 and is located at the same height as the first protruding member 301, so as to facilitate stirring of the sewage. The two ends of the rotating shaft are rotatably matched with the inner walls of the center guide wall and the outer side wall, and when the motor is driven, the rotating shaft starts to rotate.

[0032] In use, the sewage circulates in the groove body 100 and flows along the middle channel of the outer side wall 101 and the center guide wall 102, when the motor is started, the rotating shaft 201 rotates and in turn drives the aeration rotating brush 202 to rotate and stir the sewage flowing to the aeration member 200, so that air enters the sewage, and the sewage treatment speed of the oxidation ditch is accelerated.

[0033] In summary, the use of the aeration member can improve the air content in the sewage and improve the treatment performance of the water treatment device.

[0034] Embodiment 2

[0035] Referring to Figure 3 and Figure 4 , the second embodiment of the utility model, which is different from the previous embodiment, provides a protruding member of a water treatment device, and solves the problem that sludge in the sewage is easy to deposit.

[0036] Specifically, a plurality of protruding members 300 are fixedly arranged on the outer side wall 101 and the center guide wall 102. A plurality of protruding members 300 are continuously arranged on the opposite inner walls of the outer side wall 101 and the center guide wall 102, so that the sewage flowing through the groove body 100 generates a vortex, the vortex position water flow and air exchange effect is intensified, a large amount of air is mixed into the water flow, and the air content of the water flow in the channel is further improved.

[0037] Further, the cross section of the protruding member 300 is semicircular, and the diameter gradually decreases from one end to the other end along the depth direction of the water treatment device. The top portions of the protruding members 300 are tangent to each other. The height of the protruding member 300 is flush with the height of the outer side wall 101 and the center guide wall 102.

[0038] The convex piece 300 comprises a first convex piece 301 and a second convex piece 302, and the first convex piece 301 is fixedly arranged on one side of the second convex piece 302.

[0039] Preferably, the first convex piece 301 is in a semicircular shape, and the second convex piece 302 is in an inverted semicircular cone shape, and each first convex piece 301 is tangent to each other.

[0040] Preferably, the diameter of the first convex piece 301 is 1 / 10-1 / 4 of the one-side channel width of the ditch body 100.

[0041] In use, when the sewage flows through the gap between the outer side wall 101 and the central guide wall 102, the structure of the convex piece 300 causes the water flow to produce vortex fluctuation and no longer smooth, the water flow near the convex piece 300 is in large contact with air, and exchange is generated, so that air enters the sewage, improving the treatment effect of the sewage. At the same time, the conical top structure of the second convex piece 302 does not reduce the flow velocity of the water flow at the bottom position, preventing the formation of sludge deposition.

[0042] In summary, through the setting of the convex piece 300, air is more easily contacted with sewage, and sludge accumulation at the bottom of the ditch body 100 is prevented, and sewage flow is promoted.

[0043] Embodiment 3

[0044] Reference Figure 1 The third embodiment of the utility model is different from the previous embodiment, and a guide wall is provided to solve the problem of easy accumulation of sewage flow.

[0045] Specifically, the guide wall 400 is arranged in the ditch body 100 and fixedly arranged at both ends of the central guide wall 102.

[0046] Further, the guide wall 400 is fixedly arranged with two sections, which are respectively located at both ends of the inside of the ditch body 100, and are in an arc shape, dividing the corresponding ditch body 100 into two halves, and playing a role of flow division to avoid sludge deposition.

[0047] In use, when the sewage flows through the guide wall 400, it is divided into two paths and flows along the arc-shaped guide wall 400 under the guidance of the guide wall 400, and the water flow is guided by physical obstruction to avoid too fast or too slow water flow.

[0048] In summary, through the setting of the guide wall 400, the water flow of the oxidation ditch is smoother, and the treatment effect of the entire oxidation ditch is optimized.
