[0003] At present, membrane filtration technology is widely used. It is a membrane separation technology driven by pressure and is an advanced means of deep water treatment. Under a certain pressure, when raw water flows through the membrane surface, the many tiny micropores densely distributed on the membrane surface only allow water and small molecules to pass through and become permeate, while substances in the raw water with a volume larger than the micropore diameter of the membrane surface are retained on the liquid inlet side of the membrane. Membrane filtration is used to remove discoloration, odor, bacteria, viruses, etc. in the water, so that it can be directly drunk. Ceramic membranes, in particular, have the advantages of high temperature resistance, good chemical stability, high strength, and easy cleaning, and have good application prospects.

The power generation module is electrically connected to the electric water pump 7 and is used to supply the converted electric energy to the electric water pump 7 for use in an environment without power supply such as the wild. The raw water tank 5, the electric water pump 7, the filter 11, the pressure storage tank 12 and the backwash water tank 16 are connected in sequence through pipelines. The water outlet of the electric water pump 7 is also connected to the water inlet of the pressure storage tank 12 through a pipeline, and the water outlet of the backwash water tank 16 is also connected to the raw water tank 5 through a pipeline. Between the pressure storage tank 12 and the electric water pump 7, the concentrated water outlet of the filter 11 is connected to the outside world. The filter 11 is a ceramic membrane filter. The ceramic membrane filter adopts a filtering method that combines cross-flow filtration and dead-end filtration. The ceramic membrane can be cleaned during cross-flow filtration to prevent the ceramic membrane from being blocked and affecting the filtering effect. The pipeline between the pressure storage tank 12 and the backwash water tank 16 is connected to a clean water discharge pipe. The backwash water tank 16, the pipeline and the valve are set to enable backwashing of the ceramic membrane. The clean water discharge pipe is connected to the outside world. Valves are provided on the clean water discharge pipe and each pipeline. The pressure storage tank 12 is a diaphragm pressure storage tank that can store filtered clean water for drinking.

[0024] Specifically, the power generation module includes an engine 1, a coupling 2, a generator 3 and a power converter 4. The output shaft of the engine 1 is connected to the input shaft of the generator 3 through the coupling 2, and then the rotation of the engine 1 drives the generator 3 to rotate and generate electricity. The generator 3 is electrically connected to the power converter 4, and the power converter 4 is electrically connected to the electric water pump 7 to realize the conversion and output of electric energy.

[0025] The valve between the water outlet of the original water tank 5 and the water inlet of the electric water pump 7 is the main water inlet valve 6, and the pipe connected to the water outlet of the backwash water tank 16 is the backwash water pipe. One end of the backwash water pipe extends between the main water inlet valve 6 and the water inlet of the electric water pump 7, and a backwash water outlet valve 8 is provided on the backwash water pipe.

[0026] The pipeline connected to the water outlet of the electric water pump 7 is connected to a first branch pipe and a second branch pipe. The first branch pipe extends to the water inlet of the filter 11, and the second branch pipe extends to the pipeline between the clean water outlet of the filter 11 and the water inlet of the pressure storage tank 12. The valve on the first branch pipe is a filter water inlet valve 9, and the valve on the second branch pipe is a backwash valve 10.

[0027] The pipeline at the concentrated water outlet of the filter 11 is a concentrated water outlet pipe, and the valve on the concentrated water outlet pipe is a cross-flow water outlet valve 13. The three outlets of the filter 11 are a filtered water inlet 111, a filtered concentrated water outlet 112 and a filtered purified water outlet 113.

[0028] The valve between the water outlet of the pressure storage tank 12 and the water inlet of the backwash water tank 16 is the backwash water inlet valve 15 .

[0029] The pressure storage tank 12 is a diaphragm pressure storage tank.

[0030] The electric water pump 7 is provided with a pressure sensor. When the outlet valve is opened, the pressure sensor automatically turns on, and when the outlet valve is closed, the pressure sensor automatically turns off. When the cross-flow outlet valve 13 and the clean water outlet valve 14 are closed, clean water of a certain pressure will be stored in the pressure storage tank. The pressure storage tank 12 allows drinking water to be discharged quickly, and when the cross-flow outlet valve 13 is opened, some water will flow back, which has a backwashing effect and cleans the ceramic membrane.

[0031] The engine 1 is a light-duty gasoline engine.

[0032] The generator 3 can be an AC three-phase generator, an AC single-phase generator, or a DC generator. After the electric energy output by the generator 3 passes through the power converter 4, it can output AC 220V, 50Hz AC power, which can be used for the electric water pump 7, and can also be used for ordinary household appliances and lighting. The power converter 4 can also output DC 5V, 12V, 24V electric energy, which can be used for electronic equipment or other equipment that requires DC.

[0033] Through the above design, this embodiment can be used in places where there is no electricity supply to provide domestic water, hygienic and safe drinking water, and to power and charge electronic devices such as mobile phones.

[0038] (4) Before backwashing is required, the backwash water inlet valve 15 needs to be opened, and a certain amount of clean water needs to be stored in the backwash water tank 16 for backwashing; when backwashing is required, first unplug the power supply of the electric water pump 7, close the main water inlet valve 6, the filter water inlet valve 9, the clean water outlet valve 14, and the backwash water inlet valve 15, open the backwash water outlet valve 8 and the backwash valve 10, then plug in the power supply of the electric water pump 7, open the cross-flow outlet valve 13, and the clean water flows from the backwash water tank 16 under the action of the electric water pump 7, passes through the backwash water outlet valve 8 and the backwash valve 10, and then passes through the filter clean water outlet 113, and then passes through the ceramic membrane in the reverse direction and flows out from the filter concentrated water outlet 112 to achieve backwashing of the ceramic membrane.
