[0002] Existing single-village water supply equipment, such as modular water purification equipment, submerged ultrafiltration membrane water purification equipment, and pressure ultrafiltration membrane water purification equipment, has significant shortcomings in practical applications. Especially in mountainous areas with severe soil erosion, the turbidity of mountain streams and surface water is extremely high during the rainy season, leading to problems such as poor treatment effect, serious membrane fouling, and easy clogging of the above-mentioned equipment.

[0003] Furthermore, in remote mountainous areas, the lack of municipal power coverage or the high cost of establishing such systems makes it difficult for pressure-type equipment, which relies on a stable power supply, to operate. Existing equipment generally lacks the ability to adapt to drastic seasonal changes in water quality, and in the event of a malfunction, repairs are difficult due to the remote location, seriously affecting the safety of residents' drinking water. The equipment cannot automatically diagnose and clean blockages, requiring manual intervention and resulting in high maintenance costs.

The water inlet of the water storage tank 8 is... The end is connected to the main drainage pipe 6. The water outlet 52 of each ultrafiltration membrane filter 5 is connected to the main drainage pipe 6 through the drainage branch pipe 7. The dosing device 9 is connected to the top of the water storage tank 8 through a pipe. The water outlet of the water storage tank 8 is connected to the clean water delivery pipe 10. The first sewage outlet 54 of each ultrafiltration membrane filter 5 is connected to the main sewage pipe 16 through the sewage branch pipe 17. The pressure sensor 18 is provided on the raw water inlet pipe 1, the water outlet of the pre-filter 2, the main water inlet pipe 3, the main drainage pipe 6, the clean water delivery pipe 10 and the main air inlet pipe 12. The raw water inlet pipe 1 is connected to the energy storage mechanism.

[0024] The pre-filter 2 is provided with a second drain port 21 at the bottom to remove impurities it intercepts.

[0025] The backwashing system includes an air compressor 11, an air intake manifold 12, a backwashing pipe 14, and a backwashing pump 15. One end of the air compressor 11 is connected to the air intake manifold 12. The air inlet 53 of each ultrafiltration membrane filter 5 is connected to the air intake manifold 12 through an air intake branch pipe 13. One end of the backwashing pipe 14 is connected to the drain manifold 6, and the other end is connected to the clean water delivery pipe 10. The backwashing pump 15 is installed on the backwashing pipe 14.

[0026] The backwashing system is a key system for preventing ultrafiltration membrane clogging and ensuring its long-term stable operation. Air washing section: The air source is provided by the air compressor 11. Compressed air is delivered to the air inlet 53 at the bottom of each ultrafiltration membrane filter through the main air inlet pipe 12 and the air inlet branch pipe 13, and the airflow is used to wash the membrane fibers.

[0027] Water washing section: Clean water is drawn from the clean water tank by the backwash pump 15, pumped into the drain main pipe 6 through the backwash pipe 14, and then flows back into the ultrafiltration membrane module that needs to be cleaned for hydraulic flushing.

[0028] This system can achieve "air-water mixed backwashing", which has a cleaning efficiency far higher than that of water washing alone and can effectively restore membrane flux.

[0029] The raw water inlet pipe 1 is equipped with a first control valve 19, the inlet end of the pre-filter 2 is equipped with a second control valve 20, the outlet end of the pre-filter 2 is equipped with a third control valve 22, the inlet branch pipe 4 is equipped with a fourth control valve 24, and the drain branch pipe 7 is equipped with a fifth control valve 25.

[0030] The main water inlet pipe 3 is equipped with a first electric ball valve 23, and the air inlet branch pipe 13 is equipped with a sixth control valve 26. The sewage branch pipe 17 is equipped with a seventh control valve 27, the sewage main pipe 16 is equipped with a second electric ball valve 28, the drainage main pipe 6 is equipped with a third electric ball valve 29, and the backwash pipe is equipped with a fourth electric ball valve 30.

[0031] Both the main drainage pipe 6 and the clean water delivery pipe 10 are equipped with flow meters 31 to monitor the water production flow rate.

[0032] The energy storage mechanism includes a turbine generator set 32 ​​and a pipe connecting the raw water inlet pipe 1 and the turbine generator set 32. A fifth electric ball valve 33 is installed on the pipe connecting the turbine generator set 32 ​​and the raw water inlet pipe 1. Working principle: Before entering the equipment, the high-pressure raw water drives the turbine to generate electricity, converting the water's potential energy or pressure energy into electrical energy and storing it (e.g., in a battery). This provides power to the entire system's control circuits, sensors, air compressor, and backwash pump. This not only reduces dependence on mains power but also ensures normal operation of the equipment even in areas without mains power.

[0033] The equipment also includes a PLC control system, which is electrically connected to the pressure sensor 18, the flow meter 31, and the first control valve 19, the second control valve 20, the second drain outlet 21, the third control valve 22, the first electric ball valve 23, the fourth control valve 24, the fifth control valve 25, the sixth control valve 26, the seventh control valve 27, the second electric ball valve 28, the third electric ball valve 29, the fourth electric ball valve 30, and the fourth electric ball valve 33.

[0034] The built-in control logic of a PLC control system can: Based on the raw water turbidity and the pressure difference across the membrane module, the system automatically identifies and closes the valves of membrane modules that are blocked or about to become blocked, while simultaneously activating the standby membrane module to achieve uninterrupted water supply.

[0035] The backwashing program is automatically started to clean the designated membrane module.

[0036] Intelligent dosing is achieved by automatically controlling the dosing device based on water quality parameters.

[0037] All operational data (pressure, flow rate, water quality, equipment status, etc.) are uploaded through the communication module, enabling remote monitoring and control via mobile phone and computer, achieving unattended operation.

[0038] Workflow: Normal filtration process: Raw water (from reservoirs, rivers, and mountain streams) flows in through the raw water inlet pipe 1 and first undergoes preliminary filtration through the pre-filter 2 to remove large particulate impurities. The pre-treated water is then distributed to various ultrafiltration membrane filters 5 for further purification through the main inlet pipe 3 and individual inlet branch pipes 4. The purified product water is collected through the drainage branch pipes 7 and the main drainage pipe 6 and flows into the storage tank 8. The dosing device 9 intelligently adds disinfectant to the storage tank 8 based on data from online water quality monitoring instruments (not shown in the diagram, such as residual chlorine and pH meter). Finally, the qualified clean water is delivered to the user point through the clean water delivery pipe 10.

[0039] Energy storage power generation process: Before entering the equipment, the raw water flows through the energy storage mechanism. When the fifth electric ball valve 33 is opened, the high-pressure raw water drives the turbine generator set 32 ​​to operate and generate electricity. The generated electricity is stored in the battery and supplies power to the air compressor 11, backwash pump 15, all electric valves and PLC control system.

[0040] Intelligent group control and blockage diagnosis process: The PLC control system monitors the data from pressure sensor 18 and flow meter 31 in real time at the inlet main pipe 3, outlet main pipe 6, etc.

[0041] When the total transmembrane pressure difference (inlet manifold pressure - outlet manifold pressure) exceeds the preset threshold, the PLC determines that a membrane module in the system may be blocked.

[0042] The PLC sequentially selects a single ultrafiltration membrane filter as the target unit, and closes the fourth control valve 24 on the inlet pipe 4 and the fifth control valve 25 on the drain pipe 7 of all other ultrafiltration membrane filters, so that the target unit operates independently.

[0043] The PLC acquires the pressure values ​​P1 of the inlet main pipe 3 and P2 of the outlet main pipe 6 at this time, and calculates the real-time transmembrane pressure difference ΔP = P1 - P2 of the target unit.

[0044] The ΔP is compared with the reference pressure difference or preset threshold when the unit is being cleaned. If the difference is exceeded, the unit is determined to be blocked.

[0045] Once the clogged unit is located, the PLC initiates a backwashing program for that unit.

[0046] Backwashing process: For the ultrafiltration membrane filter 5 that needs cleaning, the PLC closes the valves on its inlet water pipe and product water pipe, and opens the seventh control valve 27 on its drain branch pipe and the second electric ball valve 28 on its main drain pipe 16. Simultaneously, the backwash pump 15 and air compressor 11 are started, the third electric ball valve 29 on the main drain pipe 6 is closed, and the fourth electric ball valve 30 on the backwash pipe 14 is opened. Clean water in the storage tank 8 flows backward into the ultrafiltration membrane filter 5 under the action of the backwash pump 15; simultaneously, compressed air enters through the main air inlet pipe 12 and the air inlet branch pipe 13, performing vigorous air-water mixing and scrubbing, while contaminants are discharged from the first drain port 54 through the drain branch pipe 17 and the main drain pipe 16. After flushing, the system automatically restores the filtration process of the membrane module and puts it into standby mode.

[0047] Pre-filter cleaning: After the pre-filter 2 has been running for a period of time, the second drain port 21 at the bottom can be opened manually or automatically for draining and cleaning.
