[0002] With the acceleration of urbanization and the continuous growth of the population, the demand for urban water supply is constantly increasing, and the scale of water supply plant construction is also expanding accordingly. However, urban land resources are limited, and the construction of water supply plants often requires the occupation of large areas of land, which poses a serious challenge to the conservation and efficient use of land resources.
[0003] In existing technologies, traditional water supply plant designs have the following problems:
[0004] (1) Sand filters and activated carbon filters are usually designed and constructed independently due to their large differences in size, resulting in low land use efficiency.
[0005] (2) The separate construction of the filter tank pipe gallery and backwashing equipment room is not conducive to saving investment.
[0006] (3) The interconnected pipelines between the structures are complex and not conducive to energy conservation and management.

[0053] Preferably, such as Figure 8 As shown, a first water collection well 7 is provided in the first clear water main channel 12, and the inlet end of the first water collection well 7 is connected to the outlet end of the sand filter tank 1 through the first water outlet pipe 18.
[0054] The second main water channel 13 is equipped with a second water collection well 8. The inlet end of the second water collection well 8 is connected to the outlet end of the activated carbon filter 4 through the second water outlet pipe 19.
[0055] More preferably, the second main water channel 13 is connected to a third outlet pipe 20, which is connected to the inlet end of the ultraviolet sterilizer 5.
[0056] In a further preferred embodiment, the first clear water main channel 12 is connected to a first bypass pipe 21, which is connected to a third outlet pipe 20.
[0057] Preferably, the inlet end of the ultraviolet sterilizer 5 is provided with an ultraviolet sterilization pre-pool 51, and the third outlet pipe 20 is connected to the ultraviolet sterilization pre-pool 51.
[0058] More preferably, the outlet of the ultraviolet disinfection pre-tank 51 is connected to a second bypass pipe 22, which is connected to the main outlet pipe 17, and an eighth electric gate 33 is provided on the side of the second bypass pipe 22 near the main outlet pipe 17.
[0059] In a further preferred embodiment, a first electric gate 26 is provided at the inlet end of the booster pump station 2, a second electric gate 27 is provided on the side of the third outlet pipe 20 near the pipe gallery 6, and a third electric gate 28 is provided on the side of the first bypass pipe 21 near the first clear water main channel 12.
[0060] Preferably, such as Figure 8 As shown, a first backwash pipe 23 and a second backwash pipe 24 are installed in the pipe gallery 6. The first backwash pipe 23 is connected to the first water outlet pipe 18, and the second backwash pipe 24 is connected to the second water outlet pipe 19.
[0061] A fourth electric gate 29 is installed on the side of the first water outlet pipe 18 near the first water collection well 7, and a fifth electric gate 30 is installed on the first backwash pipe 23.
[0062] A sixth electric gate 31 is installed on the side of the second water outlet pipe 19 near the second water collection well 8, and a seventh electric gate 32 is installed on the second backwash pipe 24.
[0063] More preferably, the ends of the first backwash pipe 23 and the second backwash pipe 24 are connected to the wastewater tank 10, and the ends of the first backwash pipe 23 and the second backwash pipe 24 are respectively provided with a ninth electric gate 34 and a tenth electric gate.
[0064] More preferably, the ends of the first backwash pipe 23 and the second backwash pipe 24 are connected to the wastewater pool 10 via a primary filtrate discharge pipe.
[0065] In another embodiment, such as Figure 9 As shown, a backwashing air pipe 25 is also installed in the pipe gallery 6. A backwashing blower room 9 is set on the right side of the activated carbon filter 4. A backwashing blower is placed inside the room. The backwashing blower is connected to the backwashing air pipe 25. The sand filter 1 and the activated carbon filter 4 are backwashed through the backwashing air pipe 25.
[0066] Because the residual flushing water in the filter media pores and above the filter layer is quite turbid after backwashing, the filtered water quality is poor and the turbidity is high in the initial stage of filtration after flushing. Therefore, a primary filtrate discharge pipe is installed, which shares the pipeline system with the backwash water pipe. After the filter is backwashed, the effluent is discharged into the wastewater tank 10 through the backwash pipe. After the primary filtrate is discharged, the backwash inlet valve (fifth electric gate 30, seventh electric gate 32) is closed, and the outlet valve (fourth electric gate 29, sixth electric gate 31) is opened, and the filter effluent enters the collection well.
[0067] Preferably, the booster pump station 2 and the sand filter 1 are arranged in front of and behind each other, the ultraviolet sterilizer 5 is set on the right side of the sand filter 1, and the booster pump station 2, the ozone contact tank 3, and the activated carbon filter 4 are arranged from left to right.
[0068] The pipe gallery 6 is located between the sand filter 1, the booster pump station 2, the ozone contact tank 3, and the activated carbon filter 4, and the pipe gallery 6 is equipped with a second clear water main channel 13 and a first clear water main channel 12 arranged in a front-to-back manner.
[0069] More preferably, the sand filter 1 includes multiple sets of sand filters 1 arranged side by side from left to right, and the outlet end of each set of sand filters 1 is connected to a first water collection well 7 through a first water outlet pipe 18.
[0070] The activated carbon filter 4 includes multiple sets of activated carbon filter 4 arranged side by side from left to right. The outlet end of each set of activated carbon filter 4 is connected to a second water collection well 8 through a second water outlet pipe 19.
[0071] The working principle of the above embodiments is as follows:
[0072] When the incoming water quality is poor, the fourth electric gate 29 on the first outlet pipe 18, the first electric gate 26 at the inlet of the booster pump station 2, the second electric gate 27 on the third outlet pipe 20, and the sixth electric gate 31 on the second outlet pipe 19 are opened, while the third electric gate 28 on the first bypass pipe 21 and the eighth electric gate 33 on the second bypass pipe 22 are closed. The incoming water sequentially enters the sand filter 1 through the main inlet pipe 16 and the main inlet channel 11, where suspended solids, colloidal substances, and turbidity are removed and reduced. Then, it enters the booster pump station 2 through the first clear water main channel 12 and is pumped by the booster pump. Room 2 raises the water to a certain height and enters the ozone contact tank 3; then, the organic matter is oxidized and decomposed in the ozone contact tank 3; after that, it enters the activated carbon filter 4 through the second channel 15, where the physical adsorption and biodegradation of the activated carbon filter 4 further removes residual organic matter and disinfection by-product precursors, adsorbs organic matter and odors in the water, and further improves the water quality; finally, the water treated by the activated carbon filter 4 enters the ultraviolet sterilizer 5 through the second clear water main channel 13 and the third outlet pipe 20, where the ultraviolet sterilizer 5 kills bacteria, viruses and other microorganisms in the water to ensure the biological safety of the effluent, and then discharges it from the outlet main pipe 17;
[0073] When the incoming water quality is good, the first electric gate 26 at the inlet of the booster pump station 2 and the second electric gate 27 on the third outlet pipe 20 are closed, and the third electric gate 28 on the first bypass pipe 21 is opened. The water filtered by the sand filter 1 bypasses the ozone contact tank 3 and the activated carbon filter 4 process. The water effluent from the sand filter 1 enters the UV disinfection pre-tank 51 at the inlet of the UV disinfection unit 5 directly through the first bypass pipe 21, saving energy. If the incoming water quality is very good, the eighth electric gate 33 is further opened, and the water effluent from the sand filter 1 further bypasses the UV disinfection unit 5 and is discharged from the outlet main pipe 17 through the second bypass pipe 22.
[0074] When backwashing is required for sand filter 1 and activated carbon filter 4, the fourth electric gate 29 on the first effluent pipe 18 and the sixth electric gate 31 on the second effluent pipe 19 are closed, and the fifth electric gate 30 on the first backwash pipe 23 and the seventh electric gate 32 on the second backwash pipe 24 are opened. The sand filter 1 and activated carbon filter 4 are backwashed through the first backwash pipe 23 and the second backwash pipe 24 respectively. After backwashing is completed, the ninth electric gate 34 at the end of the first backwash pipe 23 and the tenth electric gate at the end of the second backwash pipe 24 are opened, so that the wastewater discharged through the two backwash pipes is discharged into the wastewater pool 10 for temporary storage.
[0075] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
