Referring to fig. 1, in one embodiment of the present invention, an underground water treatment system 10 includes a water treatment unit 100 and a water supply unit 200, wherein the water treatment unit 100 is used for treating underground water to obtain clear water. The water treatment unit 100 is provided with a first control member for starting or stopping the operation of the water treatment unit 100. The water supply unit 200 is connected to the water treatment unit 100, and is configured to receive the clean water and supply the clean water to a user. The water supply unit 200 is provided with a first sensor for detecting the amount of fresh water. The first sensor part is controlled in an interlocking manner with the first control part.

Specifically, when the first sensing element detects that the amount of the clean water in the water supply unit 200 is less than or equal to the minimum threshold value, the first control element is turned on, so that the water treatment unit 100 operates to treat the underground water to obtain the clean water. When the first sensing member detects that the amount of the clean water of the water supply unit 200 is greater than or equal to the maximum threshold value, the first control member is closed, so that the water treatment unit 100 stops operating. When the amount of the clean water of the water supply unit 200 is less than or equal to the minimum threshold, the water treatment unit 100 operates with a workload to treat the underground water, the obtained clean water can enable the amount of the clean water of the water supply unit 200 to be more than or equal to the maximum threshold within a short time, and the amount of the clean water of the water supply unit 200 can meet the water supply amount of rural residents within a period of time under a normal state, so that the intermittent operation of relevant water treatment equipment of the water treatment unit 100 is realized, and the operation is performed with a proper workload in the operation process, so that the equipment energy consumption and the water supply cost are reduced, and the loss of the water treatment equipment is reduced.

The first control member may be one or more of a pump motor, a regulating valve, a shut-off valve, or a relay switch to cut off the supply of the water source or to stop the operation of the water supply device in the water treatment unit 100. The first sensing member may be one of a level sensor or a pressure sensor. In one embodiment, the water treatment unit 100 includes a first water-drawing pump 110, and the first water-drawing pump 110 is used for drawing groundwater. The water supply unit 200 includes a clean water tank 210, a liquid level sensor 211 is disposed on the clean water tank 210, and the liquid level sensor 211 and the motor of the first water drawing pump 110 are controlled in an interlocking manner.

The groundwater is pumped by the first water pump 110, and enters the clean water storage tank 210 for storage after being treated by the water treatment unit 100. When the liquid level of the clean water in the clean water storage tank 210 is lower than a minimum threshold value, which is detected by the liquid level sensor 211, the first water drawing pump 110 is turned on, so that the relevant equipment of the water treatment unit 100 operates, and groundwater is treated and stored in the clean water storage tank 210. When the liquid level sensor 211 detects that the liquid level of the clean water storage tank 210 is higher than a maximum threshold value, the first water drawing pump 110 stops operating, and the water treatment unit 100 stops operating.

It should be noted that the size of the clean water storage tank 210 should be set to satisfy the water supply amount of the covered rural residents for a period of time under normal conditions. For example, the clean water storage tank is designed to meet the water consumption of 10 days which is normal for the covered rural population. The minimum threshold and the maximum threshold of the liquid level can be set according to the maximum daily average water consumption of the covered rural residents and the maximum acceptable water using period.

In a preferred embodiment, in order to ensure the safety of water used by rural residents, the water supply unit 200 further comprises a first water supply pump 220, a first water outlet pipe 221 is arranged at the outlet end of the first water supply pump 220, the first water outlet pipe 221 is used for supplying water to users, and a first cut-off valve 222 is arranged on the first water outlet pipe 221.

The clean water stored in the clean water storage tank 210 is supplied to rural residential users through the first water outlet pipe 221 by the first water supply pump 220. The water can be directly supplied to farmers or indirectly supplied through a water tower or a high-level water tank. In some cases, when the liquid level of the clean water storage tank 210 is lower than the minimum threshold value, the first cut-off valve 222 is temporarily closed, the water supply to the rural residents is suspended, and meanwhile, the second cut-off valve 224 is opened, and the residual bottom water in the clean water storage tank 210 is discharged through the water discharge pipe 223, so that the water is prevented from being stored for a long time and deteriorating, and the drinking water safety of the rural residents is influenced. After the water is drained, the first shut-off valve 222 is opened, the second shut-off valve 224 is closed, the water is regenerated and the water supply is resumed.

In order to further ensure the safety of water consumption of rural residents and prevent the water in the fresh water storage tank 210 from being stored for a long time to cause deterioration, the water supply unit 200 further comprises a timing device 230, and the timing device 230 is used for recording the storage duration of the fresh water. The timer 230 is interlockingly controlled by the first shut-off valve 222 and the second shut-off valve 224. For example, when the fresh water reservoir 210 is emptied, the timing device 230 is cleared, and when the liquid level of the fresh water reservoir 210 is above a maximum threshold, the timing device 230 restarts timing. When the time recorded by the timing device 230 exceeds the maximum allowable time, no matter how the liquid level of the clean water storage tank 210 is, the first cut-off valve 222 is temporarily closed, the water supply to rural residents is suspended, and meanwhile, the second cut-off valve 224 is opened, and the residual bottom water in the clean water storage tank 210 is discharged through the drain pipe 223, so that the water is prevented from being stored for a long time and deteriorating, and the drinking water safety of rural residents is influenced. After the water is drained, the first shut-off valve 222 is opened, the second shut-off valve 224 is closed, the water is regenerated and the water supply is resumed.

Preferably, in order to prevent the fresh water from being wasted due to the discharge of the fresh water in the fresh water tank 210, the water treatment unit 100 further includes a reclaimed water tank 120, and the drain pipe 223 is connected to the reclaimed water tank 120. The clean water left at the bottom of the clean water storage tank 210 or the clean water stored for a time period exceeding the maximum time period threshold value is preferentially discharged into the reclaimed water storage tank 120 for other uses.

Further, the drain pipe 223 is also connected to an underground water well 20 for supplying groundwater. In case that the reclaimed water storage tank 120 cannot receive the remaining clean water, the remaining clean water in the clean water storage tank 210 is discharged into the underground water well 20 for recycling, thereby preventing the water from being wasted.

A first booster pump 151 is arranged at the discharge end of the multimedia filter 150 to meet the water inlet requirement of the membrane filter 160.

In a preferred embodiment, the reclaimed water storage tank 120 is provided with a reclaimed water discharge pump 121, and the outlet end of the reclaimed water discharge pump 121 is connected with the feed end of the backwashing water of at least one of the multi-media filter 150 and the membrane filter 160.

When the multimedia filter 150 and the membrane filter 160 need to be backwashed, the multimedia filter 150 and the membrane filter 160 are backwashed by using the reclaimed water stored in the reclaimed water storage tank 120, so as to improve the utilization rate of the water.

Further, the discharge ends of the back washing water of the multi-media filter 150 and the membrane filter 160 are connected with the feed end of the inclined tube sedimentation tank 140.
