[0022] It also includes an aeration generating assembly, which includes a blower 41 and an exhaust component 42. The exhaust component 42 is arranged in the MCR reaction tank 2 and close to the bottom of the MCR reaction tank 2. The exhaust component 42 has an exhaust body 421, which is connected to the blower 41 through a fourth connecting pipe 43. A plurality of exhaust ports 422 are provided in the exhaust body 421.

[0023] Specifically, in actual use of an MCR pretreatment system for use in conjunction with a seawater desalination device according to this embodiment, domestic sewage or surface water is stored in a raw water tank, and the raw water lift pump 1 is connected to the raw water tank. Thus, the raw water lift pump 1 operates to pump the domestic sewage or surface water in the raw water tank into the MCR reaction tank 2 via the first connecting pipe 11. The blower 41 operates to pump air to the exhaust body 421 via the third connecting pipe 32. The air is discharged through each exhaust port 422, thereby aerating the domestic sewage or surface water in the MCR reaction tank 2. The aeration treatment is more complete, further improving the water treatment effect.

[0024] The clear liquid formed after being processed in the MCR reaction tank 2 is transported to the cleaning water tank of the seawater desalination equipment through the second connecting pipe 31 and the third connecting pipe 32 under the operation of the water production pump 3, thereby providing clear liquid for the seawater desalination equipment.

[0025] In this embodiment, an exhaust member 42 is provided near the bottom of the MCR reaction tank 2, and the exhaust member 42 is provided with multiple exhaust holes, so that the domestic sewage or surface water in the MCR reaction tank 2 can be aerated more fully. At the same time, the water production pump 3 is used to pump the clear liquid treated by the MCR reaction tank 2 to the seawater desalination equipment, so as to provide the seawater desalination equipment with the clear liquid usage needs, which is more economical and environmentally friendly.

[0026] like Figure 1As shown, this embodiment of an MCR pretreatment system for use in conjunction with a seawater desalination device further includes an MCR water production tank 5, which is connected to a third connecting pipe 32 via a first branch pipe 51. In this embodiment, the MCR water production tank 5 is provided to store the clear liquid treated by the MCR reaction tank 2. When the water production pump 3 is operating, the clear liquid treated by the MCR reaction tank 2 enters the MCR water production tank 5 through the third connecting pipe 32 and the first branch pipe 51 for storage.

[0027] like Figure 1 As shown, the present embodiment describes an MCR pretreatment system for use in combination with a seawater desalination device, wherein the MCR pretreatment system further comprises a backwash water pump 6 and a safety filter 7; the input end of the backwash water pump 6 is connected to the bottom of the MCR water production tank 5 via a fifth connecting pipe 61, the input end of the safety filter 7 is connected to the output end of the backwash water pump 6 via a sixth connecting pipe 71, and the output end of the safety filter 7 is connected to the MCR reaction tank 2 via a seventh connecting pipe 72; the MCR reaction tank 2 is provided with a first vent pipe 21 near the bottom, and a normally closed first control valve 22 is provided on the first vent pipe 21.

[0028] Specifically, in this embodiment, the first control valve 22 is in a closed state when the MCR reaction tank 2 is performing filtering and purification work through the backwash water pump 6 and the safety filter 7; when the MCR reaction tank 2 needs to be cleaned, the first control valve 22 is opened, and the backwash water pump 6 is used to pump the clear liquid in the MCR water production tank 5 through the fifth connecting pipe 61 to the sixth connecting pipe 71, and after filtering treatment by the safety filter 7, enters the seventh connecting pipe 72, and then enters the MCR reaction tank 2, thereby cleaning the MCR reaction tank 2, and the dirty liquid after cleaning is discharged from the first vent pipe 21 to ensure the filtering and purification effect of the MCR reaction tank 2.

[0029] like Figure 1 As shown, in this embodiment, an MCR pretreatment system for use in conjunction with a seawater desalination plant is provided. The MCR reaction tank 2 is connected to a first overflow pipe 23 on a sidewall near its top. The first overflow pipe 23 is connected to a first vent pipe 21. In this embodiment, the first overflow pipe 23 is used to guide the liquid in the MCR reaction tank 2 out when the maximum liquid level exceeds the maximum liquid level, making the structure more reliable.

[0030] like Figure 1As shown, in this embodiment of an MCR pretreatment system for use with a seawater desalination plant, a second control valve 33 is provided on the third connecting pipe 32, and a third control valve 52 is provided on the first branch pipe 51. Specifically, when supplying clean liquid to the seawater desalination plant, the third control valve 52 can be closed and the second control valve 33 opened.

The first overflow pipe 23 is connected to the second vent pipe 54. A normally closed fourth control valve 55 is provided on the second vent pipe 54. This embodiment utilizes the second overflow pipe 53 to allow liquid within the MCR water production tank 5 to flow out through the second overflow pipe 53 after exceeding the maximum liquid level, making the structure more reliable. When the liquid within the MCR water production tank 5 needs to be drained through the second vent pipe 54, the fourth control valve 55 is opened to discharge the liquid.

[0032] like Figure 1 As shown, in this embodiment, an MCR pretreatment system for use in conjunction with a seawater desalination plant is described. The fifth connecting pipe 61 is connected to a second branch pipe 62 and a third branch pipe 63, which are arranged side by side. In actual use, the second branch pipe 62 is connected to the chemical wash water tank of the seawater desalination plant. Therefore, when the MCR reaction tank 2 needs to be cleaned, the chemical liquid in the chemical wash water tank of the seawater desalination plant flows through the second branch pipe 62 into the fifth connecting pipe 61, where it is mixed with the clear liquid in the fifth connecting pipe 61 and then pumped into the MCR reaction tank 2 to clean the MCR reaction tank 2. The third branch pipe 63 is connected to the water inlet of the raw water booster pump of the seawater desalination plant, thereby further providing the seawater desalination plant with clear liquid.

[0033] like Figure 1 As shown, in this embodiment of an MCR pretreatment system for use with seawater desalination equipment, a fifth control valve 621 is provided on the second branch pipe 62, and a sixth control valve 631 is provided on the third branch pipe 63. By providing the fifth control valve 621 and the sixth control valve 631, this embodiment can meet usage requirements by simply opening the corresponding control valve.

[0034] like Figure 1 As shown, in the MCR pretreatment system for use with a seawater desalination device according to this embodiment, a breathing valve 44 is connected to the fourth connecting pipe 43. By providing the breathing valve 44, the pressure of the aeration generating assembly is stabilized, making the structure more reliable.

[0035] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of protection of the present invention patent application.
