[0025] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0026] refer to Figures 1 to 4 The sewage treatment equipment according to a preferred embodiment of the utility model will be described in detail below. The sewage treatment equipment includes an equipment body 10 and a sewage treatment device 20, wherein the equipment body 10 has a liquid passage 101 and a liquid passage cavity 102 connected to the liquid passage 101, and the liquid passage 101 is used to pass sewage. That is, the sewage passed into the liquid passage 101 can pass into the liquid passage cavity 102.

[0027] The sewage treatment device 20 includes an intercepting unit 21, a liquid infusion component 22 and a phosphorus removal component 23, wherein the intercepting unit 21 is arranged in the liquid passage 101, and the intercepting unit 21 is provided with a plurality of sieve holes of a predetermined size along the direction of sewage passing in, so as to screen out large-sized solids in the sewage. The liquid infusion component 22 is arranged in the liquid passage cavity 102, and forms a liquid infusion channel 2201 for conveying sewage, and the liquid infusion component 22 can guide the sewage to be conveyed to the liquid infusion channel 2201 when the sewage passes into the liquid passage cavity 102. The phosphorus removal component 23 is arranged in the device body 10, so as to remove phosphorus from the sewage passing into the liquid infusion channel 2201.

[0028] It can be understood that the sewage introduced through the liquid passage 101 is passed into the liquid passage chamber 102 after the solids are screened out by the interception unit 21. At this time, the liquid infusion component 22 is started so that the sewage introduced into the liquid passage chamber 102 is transported to the dephosphorization component 23, so that the dephosphorization component 23 performs dephosphorization operation on the sewage.

[0029] Preferably, the liquid infusion member 22 is arranged on the bottom wall forming the liquid passage chamber 102 , so that the sewage entering the liquid passage chamber 102 can be dephosphorized by the dephosphorization assembly 23 .

[0030] Preferably, the barrier unit 21 is implemented as a grid. The liquid infusion component 22 is implemented as a lifting pump.

[0031] Specifically, the dephosphorization component 23 includes at least one liquid mixing component 231, the same number of dephosphorization agent suppliers 232 as the liquid mixing component 231, and the same number of liquid guides 233 as the dephosphorization agent suppliers 232, wherein each of the liquid mixing components 231 is arranged on the equipment body 10, and each of the liquid mixing components 231 has a liquid inlet, a liquid outlet, and a liquid mixing cavity arranged between the liquid inlet and the liquid outlet and connected to the liquid inlet and the liquid outlet. The liquid inlet of each of the liquid mixing components 231 is connected to the liquid infusion channel 2201 of the liquid infusion component 22, and the liquid outlet of each of the liquid mixing components 231 is used to discharge sewage. Each of the dephosphorization agent suppliers 232 is provided with a storage space for storing a predetermined volume of dephosphorization agent. Each of the liquid guides 233 is connected to a liquid mixing component 231 and a dephosphorization agent supplier 232, and each of the liquid guides 233 is used to guide the dephosphorization agent stored in the dephosphorization agent supplier 232 to be passed into the liquid mixing chamber. In addition, each of the liquid mixing components 231 is provided with a stirring shaft in the liquid mixing chamber, and the stirring shaft is used to stir the sewage and the dephosphorization agent passed into the liquid mixing chamber, so that the sewage and the dephosphorization agent in the liquid mixing chamber can be mixed.

[0032] Those skilled in the art can understand that, when the infusion component 22 is started to guide the sewage from the infusion channel 2201 into the mixing liquid component 231, the sewage enters the mixing liquid chamber from the liquid inlet of the mixing liquid component 231. At this time, the liquid guide 233 is started to allow the dephosphorization agent stored in the dephosphorization agent supplier 232 to be introduced into the mixing liquid chamber. At the same time, the stirring shaft of the mixing liquid component 231 is started to allow the dephosphorization agent to be fully mixed with the sewage entering the mixing liquid chamber. Due to the dephosphorization effect of the dephosphorization agent, the phosphorus substances in the sewage are removed.

[0033] In one embodiment, the number of the liquid mixing components 231 is set to two, and the two liquid mixing components 231 are arranged front and back along the sewage inlet direction, wherein the liquid inlet of the liquid mixing component 231 arranged in front is communicated with the liquid infusion channel 2201 of the liquid infusion component 22, and the liquid inlet of the liquid mixing component 231 arranged in the back is communicated with the liquid outlet of the liquid mixing component 231 arranged in the front. Correspondingly, the number of the dephosphorization agent supplier 232 and the liquid guide 233 are both set to two, and each of the liquid guides 233 is connected to one of the liquid mixing components 231 and one of the dephosphorization agent suppliers 232.

[0034] It can be understood that when the sewage is passed from the infusion channel 2201 into the mixing liquid chamber of the mixing liquid component 231 arranged in the front, the sewage first undergoes a mixing liquid dephosphorization operation and then passes into the mixing liquid chamber of the mixing liquid component 231 arranged in the rear to perform a mixing liquid dephosphorization operation. As a result, the sewage undergoes two mixing liquid dephosphorization operations, so that the phosphorus substances in the sewage can be more fully removed.

[0035] In another embodiment, the number of the liquid mixing components 231 is set to two, and the two liquid mixing components 231 are arranged in parallel, and the liquid inlets of the two liquid mixing components 231 are both connected to the liquid infusion channel 2201 of the liquid infusion component 22. Correspondingly, the number of the dephosphorization agent supplier 232 and the liquid guide 233 are both set to two, and each of the liquid guides 233 is connected to one of the liquid mixing components 231 and one of the dephosphorization agent suppliers 232.

[0036] It can be understood that the two liquid mixing components 231 arranged in parallel increase the amount of sewage guided by the liquid infusion component 22 to the liquid infusion channel 2201, thereby increasing the amount of sewage that can be dephosphorized at the same time, thereby improving the phosphorus removal efficiency of sewage.

[0037] Preferably, each of the liquid mixing components 231 is implemented as a pipeline mixer. Each of the liquid guiding components 233 is implemented as a pump.

[0038] Furthermore, the sewage treatment device 20 further includes at least one sludge deliquation assembly 24, each of which includes a liquid-passing container 241 and a screening element 242, wherein the liquid-passing container 241 has an inlet 24101, an outlet 24102, and a receiving chamber 24103 disposed between the inlet 24101 and the outlet 24102 and communicating with the inlet 24101 and the outlet 24102. The inlet 24101 is communicated with the liquid outlet of the liquid mixing member 231, so as to guide the sewage after the phosphorus removal treatment to pass through the inlet 24101 into the receiving chamber 24103 of the liquid-passing container 241. The screening element 242 is disposed in the accommodating chamber 24103 near the inlet 24101, and is arranged on the passage path of the sewage. The screening element 242 can filter out sludge when the sewage passes into the accommodating chamber 24103 from the inlet 24101, thereby dehydrating the sludge in the sewage.

[0039] Those skilled in the art can understand that sewage can pass into the containing chamber 24103 from the inlet 24101 and then flow out from the outlet 24102, that is, after the sewage passes through the dephosphorization operation of the dephosphorization component 23, the sewage passes into the containing chamber 24103 from the inlet 24101, and due to the screening effect of the screening element 242, the sludge part in the sewage passed through the inlet 24101 is retained by the screening element 242, thereby reducing the sludge content in the sewage flowing out from the outlet 24102.

[0040] Preferably, each of the liquid overflow containers 241 also forms an observation window 24104 connected to the accommodating chamber 24103, and the observation window 24104 is arranged at a position close to the screening element 242 on the side of the liquid overflow container 241 along the sewage inlet direction, and the observation window 24104 is used to install a transparent material to cover the observation window 24104.

[0041] It is understandable that the sludge will gradually accumulate on the surface of the screening element 242 after being intercepted by the screening element 242. However, as the amount of sewage passed into the liquid overflow container 241 increases, the amount of sludge accumulated on the surface of the screening element 242 will gradually increase, which will not only increase the bearing pressure of the screening element 242, but also the accumulated sludge may block the flow of sewage. Therefore, the observation window 24104 is opened on the liquid overflow container 241 to enable the staff to observe the sludge accumulation on the surface of the screening element 242 through the observation window 24104 at any time, so that when the sludge accumulated on the surface of the screening element 242 is in a serious state, the staff can promptly stop the sewage from passing into the liquid overflow container 241 by controlling the valve, and replace the screening element 242 with serious surface sludge accumulation.

[0042] In a preferred embodiment, the number of the sludge dehydration components 24 is set to two, and correspondingly, the number of the excessive liquid containers 241 and the screening element 242 are both set to two, and the two excessive liquid containers 241 are arranged in parallel, and the inlet 24101 of each of the excessive liquid containers 241 is connected to the liquid outlet of the mixing liquid component 231, thereby, when the amount of sewage that needs to be desludged increases, the total amount of sewage that can be desludged by the sludge dehydration component 24 increases, thereby improving the sludge dehydration efficiency.

[0043] Preferably, the screening element 242 is implemented as a cloth bag with a screening function.

[0044] Preferably, the equipment body 10 further forms an isolation space 103, wherein each of the liquid mixing components 231, each of the liquid guide components 233 of the phosphorus removal assembly 23, and each of the liquid overflow containers 241 of the sludge dehydration assembly 24 are arranged in the isolation space 103. The isolation space 103 enables the sewage phosphorus removal operation and the sludge dehydration operation to be performed in independent spaces, so that when the components used for the sewage phosphorus removal operation and the sludge dehydration operation are damaged and cause sewage leakage, due to the effect of the isolation space 103, the sewage is difficult to overflow and pollute the environment.

[0045] In addition, the equipment body 10 forms a sedimentation chamber 104 along the sewage introduction direction, and the sedimentation chamber 104 is connected to the outlet 24102 of the liquid overflow container 241, so that the sewage introduced into the sedimentation chamber 104 can be precipitated and processed.

[0046] Specifically, the sewage treatment equipment also includes at least one drainage pipe 30, each of the drainage pipes 30 is provided with one end passing through the isolation space 103 and the other end passing through the sedimentation chamber 104, and each of the drainage pipes 30 is connected to the liquid overflow container 241, and each of the drainage pipes 30 passing through the isolation space 103 is connected to the port of the liquid overflow container 241 forming the outlet 24102, so that the sewage that has undergone the sludge dehydration operation can be passed into the sedimentation chamber 104 through the drainage pipe 30.

[0047] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
