At present, many cities across the country have insufficient water supply, or even severe water shortage. In addition, the problem of water pollution in our country is also relatively serious, which not only further exacerbates the contradiction of water shortage, but also poses a serious threat to the drinking water safety and physical health of urban residents.

In order to alleviate the severe situation of water resources, our country actively develops various water-saving technologies in industry and agriculture, vigorously promotes the application of water-saving appliances, and strives to create a water-saving society. The reuse of urban waste water not only reduces pollution, but also alleviates the tension of water resources. In our daily life, sanitary bathing consumes the most water, and the water quality is good, but basically it is directly discharged into the sewer and cannot be further fully utilized, which leads to serious waste of sanitary water. At present, the research on water-saving technology mainly focuses on two aspects: one is the sanitary appliance itself, that is, by changing the structure or shape of the equipment or product, research and develop new high-efficiency water-saving sanitary appliances, and save water from the use of appliances; The second is the sanitary drainage system, that is, to redesign the drainage system so that it can recycle bath water to achieve the purpose of water saving.

Its purpose is to collect the daily sewage from the bathroom in an all-round way, and use it for secondary use after two-stage water treatment to achieve the purpose of saving water. Each module is described in detail below.

Sanitary ware sewage module

Sanitary appliance sewage module refers to the source of sewage generated in the bathroom and can be recycled. Generally, the family bathroom mainly includes devices such as bathtub 1, washing machine 2, washbasin 3, shower nozzle 25, etc. This system can combine these devices The discharged sewage is collected in all directions, making it fully utilized and improving the sewage recovery rate.

The washbasin 3 in the module has a high usage rate, frequent drainage, low pollution level, relatively good water quality, and can be collected for a long time. Bathtub 1 and shower nozzle 25 drainage water quality are slightly better, and pollution degree is not high, and water consumption is bigger each time, but frequency is slightly lower, can be discharged into one-level low water storage tank 8 and concentrate on collecting. The water consumption of the washing machine 2 is also large, wherein the laundry drainage is relatively dirty, while the drainage of rinsing and dehydration is relatively clean, and the water volume is relatively large. It can be selected to be directly discharged into the sewer or the first-level low water storage tank 8 according to the situation.

Specifically, the sewage generated by the sewage module of sanitary appliances is first detected by the turbidimeter 4. If the water quality is good and the turbidity is low, it flows into the first-level low-level water storage tank 8 through one of the diversion outlets of the diversion three-way solenoid valve 5. In the sewage isolation chamber 26, a filter is performed; on the contrary, if the turbidity is high, it is directly discharged into the sewer through another diversion outlet. When the sewage in the bathtub 1 and the washing machine 2 cannot all be discharged into the sewage isolation chamber 26, or when the sanitary utensil sewage is too turbid, the solenoid valve-6 can be controlled by the control processor 15, and directly discharged into the sewer without detection, if necessary Close solenoid valve 1-6 again when monitoring recovery.

Primary recycling processing module

In the filtering device 18, the filtered water flows into the secondary high-level water storage tank 17 to ensure that the filtered reclaimed water can continue to be recycled.

The diversion three-way solenoid valve 5 is mainly used to divert the sewage. There are two diversion outlets, one is the muddy water outlet, which is directly connected to the sewer, and the other is a relatively clean water outlet, which leads to the sewage isolation in the first-level low-level water storage tank 8 Chamber 26, the diversion three-way solenoid valve 5 can automatically open the diversion channel that should flow according to the indication of the turbidimeter 4, and close the other channel at the same time.

The four-way valve 22 is mainly used to control the supply of reclaimed water. It includes four channels, namely one inlet and three outlets, leading to the washing machine 2, the pool 12, and the toilet tank 14 respectively. A certain channel can be opened or closed as required. Two or three channels can also be turned on or off at the same time.

The turbidimeter 4 is mainly used to monitor the turbidity of sewage, and controls the action of the split three-way solenoid valve 5 through the control processor 15 . When the sanitary sewage flows through the turbidity meter 4, the sensor in the turbidity meter 4 senses the turbidity of the sewage to generate an electrical signal, which is transmitted to the control processor 15, and after processing, the electromagnet in the diverter three-way solenoid valve 5 is controlled to operate, and the electromagnet then Drive the spool to move to divert the sewage. The heavily polluted water is directly discharged into the sewer from the turbid water outlet of the three-way solenoid valve 5, and the less polluted water flows into the first-level low-level water storage tank 8 from the relatively clean water outlet for recovery.

The float level switch one 9 is mainly used to monitor the liquid level height in the primary low water storage tank 8, and controls the start and stop of the micro water pump 10 through the control processor 15. When the liquid level in the water storage tank 8 is close to the bottom of the water tank, the sensor induction signal on the float level switch one 9 is transmitted to the control processor 15, and after processing, the micro water pump is controlled to stop pumping water; when the primary filtered water flows into the water tank again, the liquid level rises When reaching a certain height, the sensor senses the signal and then controls the water pump to turn on.

The float level switch two 16 is mainly used for monitoring the liquid level height in the secondary high-level water storage tank 17, and controls the start and stop of the micro-water pump 10 and the switch of the solenoid valve two 19 by the control processor 15. When the water storage tank 17 was full capacity, that is, when the liquid level was close to the top cover of the water tank, the sensor induction signal on the float level switch 2 16 was transmitted to the control processor 15, and after processing, the micro water pump was controlled to stop the water supply; when the clear water in the water tank was discharged again After use, when the liquid level drops to a certain height, the sensor senses the signal and then controls the water pump to start water supply, so that the primary filtered water can be recycled in time. When the float level switch 9 and 16 control the start and stop of the water pump contradictory, it is preferred to control the water pump to stop. When the liquid level in the water storage tank 17 was close to the bottom of the water tank, the sensor sensing signal on the float level switch 2 16 then controlled the solenoid valve 2 19 to open, replenishing tap water to the water tank; when the liquid level rose to a certain height, the sensor sensing signal and then Control electromagnetic valve two 19 and close, stop supplying running water, so that save water.

Work process of the present invention is as follows:

The present invention can complete the all-round collection of all sewage in the bathroom during implementation, and automatically recycle after recycling. During specific implementation, first open the shunt three-way electromagnetic valve 5, the check valve 11, the stop valve 21 and the four-way valve 22, and other valves are closed, and all electrical equipment is energized.

When using the washbasin 3, the tap water is supplied through the pipe section ABCC', the sewage is discharged from the outlet G, and flows to the turbidimeter 4 through the pipe section GG'HH'; when the bathtub 1 is used, the tap water is supplied through the pipe section ABCD, and the sewage is discharged from the outlet D'. It flows to the turbidity meter 4 through the pipe section D'F'G'HH'; when using the washing machine 2, it supplies water through the pipe section EE', and the sewage is discharged from the outlet F, and flows to the turbidimeter 4 through the pipe section FF'G'HH'; During the shower nozzle 25, tap water is supplied through pipe section ABB ', and bath sewage flows into the sewage isolation chamber 26 through the filter plate 28 on the top cover of the first-level low water storage tank 8 . The sewage discharged from the bathtub 1, the washing machine 2, and the washbasin 3 is monitored by the turbidity meter 4, and the diversion three-way solenoid valve 5 is controlled by the control processor 15 according to the degree of turbidity. The water flows out from the outlet J, and is discharged to the sewer through the pipe section JJ′K′L′M′N′, and the water with low turbidity flows out from the relatively clean water outlet I, and flows into the sewage isolation in the first-level low-level water storage tank 8 through the pipe section II′ Room 26. When the user chooses to discharge the sewage directly to the sewer, or when the sewage in the washing machine and the bathtub is not completely discharged, the solenoid valve-6 can be controlled by the control processor 15, so that the sewage can be discharged through the pipe section H J'K'L'M'N' into the sewer.

When the sewage in the sewage isolation chamber 26 is filtered through the primary filter device 7, the speed is lower than the sewage inflow velocity. When the isolation chamber is full, it can flow out through the overflow pipe 24 provided in the primary low water storage tank 8. It is directly discharged into the sewer through the pipe section KK'L'M'N'. Sewage enters the first-level filter device 7, is filtered by three layers of filter elements, and flows out from the bottom, which is primary filtered water, and flows into the first-level low-level water storage tank 8, and the liquid level gradually rises. When it is higher than a certain height, the float level switch The induction signal of -9 controls the micro water pump 10 to turn on through the control processor 15, and the water pump starts to pump water, and the primary filtered water is transported to the secondary high-level water storage tank 17 through the pipeline OO'A'P. If the water storage tank 17 is full, the water pump does not will be on, still off. When the water in the water storage tank 8 was evacuated, the liquid level was close to the bottom surface of the water tank, and the float level switch-9 induction signal was controlled by the control processor 15 to close the micro-water pump 10, and the water pump stopped pumping. Repeating this cycle again and again can ensure that the primary filtered water can be transported to the secondary high-level water storage tank 17 in time, so that it can be recycled as soon as possible. The bottom of the primary low-level water storage tank 8 is provided with a discharge outlet L. When maintaining and cleaning the water tank, the solenoid valve 20 can be controlled by the control processor 15 to open, and the water flows through the pipe section LL'M'N' and is directly discharged into the sewer.

The primary filtered water enters the secondary high-level water storage tank 17 from the water inlet P, first passes through the secondary filter device 18, and is filtered by five layers of filter elements to obtain reclaimed water, which flows out from the bottom and enters the water tank, and the liquid level gradually rises. , the liquid level is close to the top cover of the water tank, the induction signal of the float level switch 2 16 is controlled by the control processor 15 to close the micro-water pump 10, and the water pump stops conveying once-filtered water. After the water in the water storage tank 17 flows out from the bottom outlet P' for reuse, the liquid level gradually drops. When it is lower than a certain height, the induction signal of the float level switch 2 16 controls the micro water pump 10 to turn on through the control processor 15, and the water pump continues One supply of filtered water. If there is no water in the first-level low water storage tank 8 at this moment, then the miniature water pump 10 can not be opened, and is still in closed state. With the discharge of reclaimed water, the liquid level in the water storage tank 17 continues to decrease. When it is close to the bottom, the induction signal of the float level switch 2 16 is controlled by the control processor 15 to control the solenoid valve 2 19 to open. Tap water is replenished in the water tank 17, and the liquid level rises gradually again, and when higher than a certain height, the induction signal of the float level switch two 16 is closed by the control processor 15 and then controls the solenoid valve two 19. The set value of this height needs to be lower than the height at which the water pump is controlled by the float level switch 2 16, so that the primary filtered water can be replenished in time, and it can be used preferentially after secondary filtration. Repeating this cycle again and again can ensure that the secondary high-level water storage tank 17 can supply reclaimed water to the reclaimed water reuse module in time, which is convenient for users to use.

The secondary filtered reclaimed water flows out from the outlet P' at the bottom of the secondary high-level water storage tank 17, and begins to divert through the four-way valve 22 to supply water to the reclaimed water reuse module. When the toilet 13 is used, the water is transported to the toilet tank 14 through the pipe section P'QQ', and the sewage produced is discharged into the sewer through the pipe section NN'; Sewer: When using the washing machine 2, the water is transported through the pipe section P′EE′, and the generated sewage is discharged from the outlet F, and enters the first-level recovery and treatment module to form a complete sewage recycling cycle.

The present invention can be modified or supplemented according to the actual situation during specific implementation. For example, the system can be expanded to introduce kitchen sewage for recycling, and the system can also be simplified by removing the high-level water tank and improving the filtration level in the low-level water tank, thereby reducing costs and saving space, the system can also be modified to better suit user needs.
