The medicine liquid member 22 is connected to the mixing space 2301 of the mixing member 23, the medicine liquid member 22 stores medicine liquid inside, and the mixing member 23 can suck the medicine liquid in the medicine liquid member 22 into the mixing space 2301 and mix with the sewage to perform chemical treatment on the sewage.

[0032] As an example, the sewage driving member 21 is implemented by a pump.

[0033] Preferably, the medicine liquid member 22 comprises a medicine liquid container 221 and a medicine liquid driving member 222, wherein the medicine liquid container 221 is connected to the medicine liquid driving member 222 by a pipeline, the medicine liquid driving member 222 is connected to the mixing space 2301 of the mixing member 23 by a pipeline, and the medicine liquid driving member 222 can drive the medicine liquid inside the medicine liquid container 221 to enter the mixing space 2301 by the pipeline to avoid that the mixing member 23 cannot suck the medicine liquid due to too small suction force.

[0034] As an example, the medicine liquid driving member 222 is implemented by a pump.

[0035] The device body 10 further forms a second treatment space 102. The filtering assembly 30 further comprises a second filtering member 32, the second filtering member 32 comprises a filtering body 321 and a filtering member 322, wherein the filtering body 311 has an overflow space 32101, the filtering member 322 is installed in the overflow space 32101 and forms a filtering space 32201, the filtering space 32201 is connected to the mixing space 2301 and connected to the overflow space 32101 by a plurality of small holes, and the overflow space 32101 is connected to the second treatment space 102. In this way, the sewage mixed with the medicine liquid in the mixing space 2301 of the mixing member 23 flows into the filtering space 32201 of the filtering member 322, and passes through the overflow space 32101 into the second treatment space 102 under the filtering of the filtering member 322 to complete further treatment on the sewage.

[0036] Preferably, the filter 322 is vertically arranged in the overflow space 32101 of the filter body 321, the upper end of the filter 322 is connected to the mixing space 2301 of the mixing member 23 through a pipe, and the part of the sidewall of the filter body 321 close to the bottom is connected to the pipe and communicates with the second treatment space 102, so that the bottom of the filter 322 is preferentially cleaned after the backwashing of the sewage, thereby avoiding the deposition of dirt on the bottom of the filter 322.

[0037] The backwashing assembly 40 comprises a backwashing member 41 and a base 42, wherein the base 42 is mounted on the device body 10, and the upper end of the filter body 321 is connected to the mixing space 2301 of the mixing member 23 through a pipe. The lower end of the filter body 321 is detachably connected to the base 42. The backwashing member 41 is mounted on the pipe connecting the second treatment space 102 and the overflow space 32101, and the backwashing member 41 communicates with the overflow space 32101 and the second treatment space 102, so that the backwashing member 41 can guide the sewage in the overflow space 32101 to the second treatment space 102 or backwash the sewage in the second treatment space 102 to the overflow space 32101.

[0038] As an example, the backwashing member 41 is implemented by a negative pressure pump.

[0039] As can be understood by those skilled in the art, when the second filter member 32 is filtering, the backwashing member 41 guides the sewage in the overflow space 32101 to flow into the second treatment space 102; when dirt deposits inside the filter 322, the operator can operate the filter body 321 so that the lower end of the filter body 321 is not firmly connected to the base 42, at this time, the backwashing member 41 backwashes the sewage into the overflow space 32101 and impacts the inside of the filter space 32201 from the outer wall of the filter 322, thereby vibrating the filter 322 to reduce the dirt on the inner wall of the filter 322, prolonging the service life of the filter 322 and avoiding the deposition of dirt on the bottom of the filter 322 to affect the treatment of sewage.

[0040] Preferably, the outer wall of the end of the filter body 321 is formed with external threads, the inside of the base 42 is formed with internal threads, the filter body 321 is screwed to the base 42, and when the filter body 321 is rotated away from the base 42, the filter body 321 is not firmly connected to the base 42.

[0041] It is worth mentioning that when the filter body 321 is connected to the pipe, the filter body 321 is difficult to rotate, in other words, the filter body 321 is not rotated to a large enough angle with one end connected to the pipe, which can not cause the filter body 321 to be disconnected from the base 42.

[0042] Preferably, the base 42 comprises a base body 421 and a movable member 422, wherein the base body 421 is fixed to the device body 10. The movable member 422 is arranged in a ring shape, the outer wall of the movable member 422 is threadedly connected to the base body 421, and the inner wall of the movable member 422 is threadedly connected to the filter body 321. An operator can rotate the movable member 422 to disconnect the movable member 422 from the base body 421 to cause the filter body 321 to be disconnected from the end of the base 42, while avoiding the filter body 321 from rotating.

[0043] Preferably, the shock-absorbing assembly 40 further comprises a buffer member 43, which comprises a joint body 431, at least one pair of buffer members 432, and at least one mounting member 433, wherein the joint body 431 is arranged around the communication pipe of the filter body 321, and the joint body 431 is formed with at least two pairs of buffer holes 43101 in the vertical direction. Each pair of buffer members 432 is arranged to be mounted in a pair of buffer holes 43101, and each mounting member 433 is fixed to the device body 10 by penetrating a pair of buffer members 432. In this way, the joint body 431 and the mounting member 433 are abutted by the buffer members 432 in the transverse direction. Since the mounting member 433 is fixed, when the filter body 321 vibrates, the joint body 431 is driven to vibrate and press against the buffer members 432, thereby absorbing part of the vibration force under the buffering action of the buffer members 432, and limiting the vibration of the upper end of the filter body 321, thereby avoiding excessive vibration of the filter body 321 and water leakage.

[0044] As an example, the buffer members 432 are implemented to comprise spherical springs.

[0045] Preferably, the mounting member 433 comprises a mounting main body 4331, a mounting sub-body 4332 and a pair of fixing pins 4333, wherein the mounting main body 4331 and the mounting sub-body 4332 are respectively arranged on the upper and lower sides of the pair of buffer holes 43101 of the joint main body 431, and the mounting main body 4331 is fixed to the device main body 10. Each of the fixing pins 4333 penetrates the mounting main body 4331, the mounting sub-body 4332 and one of the buffer holes 43101, so that the joint main body 431 is clamped by the mounting member 433 to avoid separation of the joint main body 431 from the mounting member 433.

[0046] Preferably, the mixing member 23 comprises a mixing main body 231 and a stirring member 232, wherein the mixing space 2301 is formed by the mixing main body 231, and the mixing space 2301 is communicated with the interior of the liquid medicine member 22 and the pipeline communicated with the sewage driving member 21. The stirring member 232 is installed in the mixing space 2301 of the mixing main body 231, and the stirring member 232 can rotate spirally and push the sewage and the liquid medicine in the mixing space 2301 to the second filtering member 32.

[0047] As an example, the stirring member 232 is implemented to comprise a rotatable spiral blade.

[0048] It can be understood that when the stirring member 232 rotates, the liquid in the mixing space 2301 is pushed to the second filtering member 32, at this time, a negative pressure is generated in the interior of the mixing space 2301, and since the interior space of the liquid medicine member 22 is communicated with the mixing space 2301, the liquid medicine in the interior of the liquid medicine member 22 can enter the mixing space 2301 and mix with the sewage due to the rotation of the stirring member 232, and then enter the second filtering member 32 under the pushing of the stirring member 232.

[0049] Preferably, the number of the liquid medicine members 22 is implemented to be at least two, and a plurality of the liquid medicine members 22 are all communicated with the mixing space 2301 of one of the mixing main bodies 231, and the liquid medicine in the interior of the plurality of the liquid medicine members 22 can be set to be of different components, so that different liquid medicines can be mixed in the mixing space 2301 to treat the sewage.

[0050] Preferably, the number of the mixing members 23 is implemented to be the same as the number of the liquid medicine members 22, each of the liquid medicine members 22 is communicated with the mixing space 2301 of one of the mixing main bodies 231, and the mixing spaces 2301 of two adjacent mixing main bodies 231 are communicated. In this way, different liquid medicines can be mixed with the sewage in sequence, which facilitates the use of certain liquid medicines.

[0051] Preferably, the filtering assembly 30 further comprises a third filtering member 33, which is installed in the second processing space 102, and is capable of further processing the sewage filtered by the second filtering member 32.

[0052] As an example, the third filtering member 33 is implemented as a MBR sewage treatment device.

[0053] Preferably, the device body 10 further comprises a third processing space 103, which is connected to the portion of the first processing space 101 away from the sewage inlet, and the sewage driving member 21 is installed in the third processing space 103, so as to avoid the sewage driving member 21 being hindered by the first filtering member 31 in the first processing space 101.

[0054] Preferably, the sewage treatment device further comprises a plurality of valve members 50, wherein the communication pipeline between each of the liquid medicine members 22 and the mixing body 231 is provided with the valve member 50, and the flow direction of the valve member 50 is set to be from the liquid medicine member 22 to the mixing body 231, so as to avoid the sewage in the mixing body 231 flowing into the liquid medicine member 22 and polluting the inner wall of the liquid medicine member 22.
