[0002] In the existing technology, the process technology of river water purification is mainly divided into physical method, chemical method and biological method. Among them, the physical method mainly involves building new coagulation and sedimentation facilities near the river to purify water quality. It has the characteristics of high technical requirements, large land area and huge investment, and is difficult to promote and implement on a large scale.

[0003] Chemical methods usually achieve the purpose of purifying water quality by throwing purification agents into the river. However, the river water is usually mixed with a large amount of solid pollutants such as silt, which will affect the purification effect of the chemical method. In addition, river pollution also has the problem of uneven distribution in time and space. Traditional treatment technology has the disadvantages of large one-time investment and difficult to move facilities, which makes it impossible to purify the river in a specific area on a regular basis.

[0023] The utility model will be further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, the integrated river water purification and treatment machine includes an outer casing 1, in which a lifting pump 2, a coarse filtration unit 3, a sterilization unit and a fine filtration adsorption unit 6 are sequentially connected. In this embodiment, the outer casing 1 is made of stainless steel. The outer casing 1 is 1500 mm long, 1000 mm wide and 1000 mm high.

[0025] The lifting water pump 2 is connected to the river channel through the first water inlet pipe. Driven by the lifting water pump 2, the treated river water is passed into the multi-media filtration unit to adsorb small suspended particles in the treated river water. In this embodiment, a stainless steel filter is provided at the water inlet of the lifting water pump 2 to filter branches, leaves or large suspended particles in the introduced river water.

[0026] The coarse filtration unit 3 includes a water valve, a first water pipe 3-1, a multi-media filter 3-2, and filter material arranged in the multi-media filter 3-2. The water valve is arranged at the top of the multi-media filter 3-2 to control the entry of the treated river water. The water valve is provided with a water inlet and a water outlet. The water inlet is connected to the drain outlet of the lifting water pump 2 through the first water pipe 3-1.

[0027] A filter chamber is provided on the multi-media filter 3-2. The filter material is arranged in the filter chamber, which includes quartz sand, activated carbon and anthracite arranged layer by layer. Furthermore, a second water inlet pipe connected to the water inlet of the water valve is arranged in the filter chamber. The second water inlet pipe is arranged vertically, and the water outlet is located at the bottom of the filter chamber, so that the treated river water introduced from the water inlet of the water valve can be fully contacted and filtered with the filter material during the process of rising water level, and discharged from the water outlet of the water valve by overflow.

[0028] The water outlet of the water valve is provided with a second water pipe 7 connected to the sterilization unit. The treated river water filtered by the multi-media filter 3-2 flows to the sterilization unit through the second water pipe 7 for sterilization.

[0029] The sterilization unit includes a chemical sterilization mechanism 4 and a physical sterilization mechanism 5. The water outlet of the second water pipe is connected to the water inlet of the physical sterilization mechanism. The second water pipe 7 is provided with a first branch connected to the chemical sterilization mechanism 4. The output end of the chemical sterilization mechanism 4 is connected to the first branch of the second water pipe 7.

[0030] In this embodiment, the chemical sterilization mechanism 4 adopts an automatic dosing device. The automatic dosing device is loaded with agents for dosing, such as chlorine dioxide tablets, sodium hypochlorite tablets, and chlorine tablets. The treated river water flowing through the second water pipe 7 is initially sterilized under the action of the dosed agent. At the same time, the automatic dosing device can dose a fixed amount of agents into the treated river water, thereby avoiding secondary pollution of the treated river water caused by excessive agents.

[0031] Furthermore, the water inlet of the physical sterilization mechanism 5 is connected to the water outlet of the second water pipe 7, and a first switch valve is provided at the water outlet of the second water pipe 7 to control the conduction or cutoff of the treated river water in the second water pipe 7. The physical sterilization mechanism 5 adopts an ultraviolet sterilizer. The treated river water is subjected to secondary sterilization treatment under the action of ultraviolet rays to avoid bacterial residue.

[0032] In this embodiment, a second branch is provided on the second water pipe 7. A water pipe 9 is connected to the second branch. A second switch valve for controlling the conduction or cutoff of the water pipe 9 is provided on the water pipe 9. In the initial state, the first switch valve on the second water pipe 7 is in the conduction state, and the second switch valve on the water pipe 9 is in the cutoff state, so that the treated river water in the second water pipe 7 can smoothly enter the ultraviolet sterilizer. When the ultraviolet sterilizer is damaged, the first switch valve is in the cutoff state, and the second switch valve on the water pipe 9 is in the conduction state, so that the treated river water can be diverted from the water pipe 9 to the outside to avoid interference with the maintenance of the ultraviolet sterilizer by the staff.

[0033] In addition, in this embodiment, the water valve adopts a reversing valve, and a sewage outlet is provided on the reversing valve for backwashing with the multi-media filter 3-2. When the filter chamber needs to be flushed and cleaned. The reversing valve is adjusted to a state where the water inlet and the sewage outlet are connected, and clean water is introduced into the filter chamber through the lifting water pump 2. The clean water passes through the second water inlet pipe and flushes the bottom of the filter chamber. At the same time, as the water level rises, the inner wall of the filter chamber is cleaned. The sewage after flushing is discharged from the sewage outlet.

[0034] like Figure 1As shown, the water outlet of the ultraviolet sterilizer is provided with a third water pipe 8 connected to the water inlet of the fine filtration adsorption unit 6. The treated river water flows into the fine filtration adsorption unit 6 through the third water pipe 8 for fine filtration treatment.

[0035] The fine filtration adsorption unit 6 includes a filter body, a filter element, a drain valve, a pressure gauge and a controller. The outer shell of the filter body is made of SUS304 stainless steel. The filter element is a 1-5 μm filter element. The pressure gauge is used to measure the water pressure of the treated river water flowing through the filter body. The drain valve is set at the water outlet of the filter body and is turned on or off under the control of the controller, thereby controlling the discharge or retention of the purified treated river water.

[0036] In this embodiment, the first water inlet pipe, the first water pipe 3 - 1 , the second water pipe 7 , the water pipeline 9 and the third water pipe 8 are all made of UPVC material.

[0037] The working principle of the utility model is as follows:

[0038] The integrated river water purification and treatment machine is moved to the vicinity of a polluted river with a water temperature below 50 degrees and a pH value greater than 4 degrees. The lifting pump 2 is connected to the river through the first water inlet pipe. Driven by the lifting pump 2, the treated river water passes through the coarse filtration unit 3, the sterilization unit and the fine filtration adsorption unit 6 in sequence. Among them, the water inlet pressure is 0.2~0.6MPA under the control of the lifting pump 2.

[0039] The treated river water entering the coarse filtration unit 3 is discharged from the bottom of the filtration chamber under the guidance of the second water inlet pipe, and is fully contacted and filtered with the filter material during the rising water level, and flows to the sterilization unit from the outlet of the water valve by overflow.

[0040] The automatic dosing device in the sterilization unit quantitatively doses chlorine dioxide tablets, sodium hypochlorite tablets, chlorine tablets and other agents into the treated river water for preliminary sterilization. The amount of agents dosed each time is 7 kg.

[0041] The treated river water that has completed the initial sterilization is sent to the ultraviolet sterilizer. Under the action of ultraviolet rays, the treated river water undergoes secondary sterilization.

[0042] The treated river water after the sterilization treatment is passed into the fine filtration adsorption unit 6. The treated river water is further filtered by the filter element in the fine filtration adsorption unit 6 and discharged to the outside after the filtration is completed.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
