Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to Fig. 1, Fig. 1 shows a schematic diagram of the pipeline connection of the residential wastewater collection and utilization system proposed by the present invention. As shown in FIG. 1 , waste water sources include bath water 1 , kitchen water 2 , washing machine drainage 3 and air conditioner condensate 4 . In daily life, the composition of residential wastewater varies greatly. Bathing water1 refers to the wastewater generated by people in the bathroom, usually after bathing. This wastewater usually includes detergent residues, such as shampoo, shower gel, soap, etc. ingredients, but the residual concentration of these detergents is not large. From the naked eye, the bath water 1 is relatively clean, and does not contain solid impurities such as sediment, particles, etc., mainly including various detergent residues left by bathing , so the bath water 1 can be reused after simple water treatment; the kitchen water 2 is different from the bath water 1, the use of the kitchen water 2 is relatively complicated, and the composition of the waste water is also diverse. When people wash the tableware (referring to Tableware after eating), due to the influence of Chinese catering culture, tableware after eating usually contains heavy oil stains. After using detergents such as dishwashing liquid, the kitchen water 2 not only includes detergents, but also Including oil pollution, and the content of oil pollution in kitchen water 2 is closely related to the eating habits of various regions in China. For example, hot pot in Sichuan and Chongqing belongs to heavy oil food, and the content of oil pollution in kitchen water 2 in these areas is obviously higher. , Kitchen water 2 generally refers to the sewage in the kitchen water 2 tank, and when washing vegetables or fruits, kitchen water 2 will become relatively clean waste water. At this time, the waste water does not contain oil and only contains a very small amount of mud Impurities such as sand and dust particles only need simple filtration at this time, and the kitchen water 2 can be used as relatively clean wastewater for secondary use. Therefore, for the collection and reuse of kitchen water 2, it is first necessary to distinguish whether kitchen water 2 contains oil, and determine the specific direction and application of kitchen water 2 according to the results of the distinction; compared with bath water 1 and kitchen water 2, The washing machine drainage 3 is basically divided into two types, one is the drainage of the normal laundry mode, and the other is the drainage of the dehydration mode. 3 is waste water containing laundry liquid. In the dehydration mode, since the clothes are basically in the state after rinsing during dehydration, that is, the clothes themselves do not contain or contain a very small amount of detergent (laundry liquid, washing powder, soap), Therefore, the washing machine drainage 3 at this time is basically in the state of clean water, and can be reused without treatment. Therefore, the washing machine drainage 3 also needs to be classified into types for reuse; the air-conditioning condensate 4 has a certain seasonality, that is, only the air-conditioning is turned on in summer When cooling, the indoor unit of the air conditioner will produce condensed water. The condensed water does not contain pollutants such as detergents. The condensed water only contains some dust, so it can also be used directly. To sum up, for residential buildings, due to the variety of wastewater sources and the variety of wastewater produced by each wastewater source, it is necessary to distinguish and classify the wastewater generated by the wastewater source, and determine the wastewater re-treatment according to the degree of pollution of the wastewater. The specific purpose of utilization, rather than simply collecting and utilizing wastewater.

According to the above analysis, the waste water collection and utilization system of the present invention mainly classifies the waste water through the concentration sensor and the temperature sensor 28, and utilizes the first water tank 11, the second water tank 12, the third water tank 13 and the waste water tank 7 to collect the waste water, At the same time, according to the different pollution levels of waste water, the waste water is introduced into the toilet 5, the mop pool 6, the garden water 8, and the cleaning equipment 9, so as to realize the cascade utilization of waste water and improve the utilization efficiency of waste water.

As shown in Figure 1, the water outlet of the bath water 1, the water outlet of the kitchen water 2 and the water outlet of the washing machine drainage 3 all converge at the water inlet of the water processor 10, and the water outlet of the water processor 10 is connected with the first water tank 11 The bath water 1, the kitchen water 2 and the washing machine drainage 3 are centrally treated through the water processor 10, and the water after centralized treatment enters the first water tank 11 for storage. 2 and washing machine drainage 3 are provided with branch roads on the water outlet. This is because the pollutant content in the waste water of kitchen water 2 and washing machine drainage 3 may change greatly under different working modes (use conditions), such as kitchen water 2 and washing machine drainage 3. When water 2 only uses tap water to wash fruits or vegetables, the waste water produced does not contain detergent, and the waste water produced by the washing machine in dehydration mode does not contain detergent. Classification, when the kitchen water 2 contains detergent (i.e. when using dishwashing liquid to wash dishes or pots), the kitchen water 2 at this time enters the water processor 10 for purification treatment, when the kitchen water 2 does not contain detergent (Promptly adopt tap water to carry out clean water washing, for example when washing fruits and vegetables), the kitchen water 2 at this time directly enters the second water tank 12 by the branch; When 26 is greater than the maximum threshold (such as the drainage generated during the first rinsing), the washing machine drainage 3 directly enters the waste water tank 7 and is no longer reused. When the washing machine drainage 3 contains less detergent, that is, the second concentration sensor 26 is greater than When the minimum threshold is less than the maximum threshold (such as other drainages except for the first time), the washing machine drainage 3 enters the water processor 10 for purification treatment, and then enters the first water tank 11 for storage. When the washing machine drainage 3 does not contain detergent (such as dehydration mode), that is, when the second concentration sensor 26 is less than the minimum threshold value, the washing machine drainage 3 directly enters the second water tank 12 for storage, so the washing machine drainage 3 is divided into three levels, i.e. high pollution level: the second The detection value of the concentration sensor 26 is greater than the maximum threshold, medium pollution level: the detection value of the second concentration sensor 26 is greater than the minimum threshold and less than the maximum threshold; low pollution level: the detection value of the second concentration sensor 26 is less than the minimum threshold. Referring to Fig. 1, for the washing machine drainage 3, the pipeline setting is specifically: a second concentration sensor 26 is installed at the outlet of the washing machine drainage 3, and the pipeline downstream of the second concentration sensor 26 is divided into two branches, as shown in Fig. 1 Shown, the branch to the left communicates with the pipeline of the kitchen water 2 outlet, and sets the first solenoid valve 14 and the second solenoid valve 15, and the branch to the right connects the waste water tank 7 and sets the third solenoid valve 16. When the second concentration sensor 26 is greater than the maximum threshold, the second solenoid valve 15 is closed, the third solenoid valve 16 is opened, and the washing machine drain 3 directly enters the waste water tank 7; when the second concentration sensor 26 is greater than the minimum threshold and less than the maximum threshold, the second The three solenoid valves 16 are closed, the first solenoid valve 14 and the second solenoid valve 15 are opened, and the washing machine drainage 3 enters the water processor 10 to be purified, and then enters the first water tank 11 for storage; when the second concentration sensor 26 is less than the minimum threshold, The first solenoid valve 14 and the third solenoid valve 16 are closed, the second solenoid valve 15 and the fifth solenoid valve 18 are opened, and the washing machine drain 3 directly enters the second water tank 12 for storage.

For the classification of kitchen water 2, due to its special use, kitchen water 2 can be divided into two grades, that is, waste water containing oil pollution and waste water without oil pollution. For cleaning tableware after meals, such as cleaning bowls, plates, chopsticks, spoons, pots, etc. after eating, a large amount of detergent is usually added. This waste water contains a lot of oil pollution; waste water that does not contain oil pollution can be used Washing with tap water and without dish soap, e.g. washing fruits and vegetables in 2 sinks of kitchen water. As shown in Figure 1, a first concentration sensor 25 is set at the water outlet of the kitchen water 2, and the waste water of the kitchen water 2 is classified by the first concentration sensor 25 and the waste water after classification is introduced into the first water tank 11 or the second water tank 12 , specifically: when the detection value of the first concentration sensor 25 is greater than a predetermined threshold, it indicates that the kitchen water 2 is wastewater containing oil pollution, the first electromagnetic valve 14 is opened, and the fifth electromagnetic valve 18 is closed. At this time, the kitchen water 2 The waste water enters the water processor 10 to be purified, and then enters the first water tank 11; when the detection value of the first concentration sensor 25 is less than a predetermined threshold, it indicates that the kitchen water 2 is waste water that does not contain oil pollution, and the first solenoid valve 14 Closed, the fifth electromagnetic valve 18 is opened, now the waste water of kitchen water 2 enters the second water tank 12 for storage, and the water of the second water tank 12 can be directly exported to the mop pool 6, thereby being used for rinsing the mop.

As can be seen from the above description, the cleanliness of the water stored in the first water tank 11 is less than that of the water stored in the second water tank 12, that is, relatively clean water is directly stored in the second water tank 12 and can be directly used in the second water tank 12. The water in the second water tank 12 is supplied to the mop pool 6, thereby utilizing relatively clean water to flush the mop; although the water in the first water tank 11 has been processed by the water processor 10, it still belongs to The waste water with lower cleanliness, that is, the waste water in the first water tank 11 is more suitable for the use of the toilet 5, but not suitable for the use of the mop pool 6.

As shown in Figure 1, a connecting pipeline is set between the first water tank 11 and the second water tank 12, that is, the second water outlet of the first water tank 11 is connected to the second water tank 12 and the second water outlet of the first water tank 11 is connected to the second water tank 11. A fourth electromagnetic valve 17 is arranged on the pipeline of the second water tank 12 . Due to the influence of the number of people in the house, for example, taking a normal family of three as an example, the amount of wastewater in the bathing water 1 is much greater than that of the kitchen water 2, washing machine drainage 3 and air-conditioning condensate 4, so the volume of the first water tank 11 is also the largest, but For residential buildings, the capacity of the first water tank 11 cannot be set too large, for example, 60L can be set, so it is necessary to set the buffer device for the first water tank 11 so as to accept the waste water produced by excessive bathing water 1, for the buffering of the volume of the water tank Generally speaking, the current conventional setting in this field is to connect a buffer water tank in series, but as mentioned above, the water tanks of the residence cannot be set in multiples without limit or the setting is too large, and comprehensive factors such as residential area and house type need to be considered. Therefore, the present invention Adopt the second water tank 12 as the buffer of the first water tank 11, promptly the second water outlet of the first water tank 11 is connected with the second water tank 12, and the fourth solenoid valve 17 is set, when the water level in the first water tank 11 reaches the upper limit, The fourth electromagnetic valve 17 is opened, and the water in the first water tank 11 is delivered to the second water tank 12, which can ensure that the water in the first water tank 11 will not overflow, and further ensure that the bath water 1 is fully recovered, especially for bathing at night Bathing water can be fully recovered during peak hours1.

For the second water tank 12, when the first water tank 11 cannot accommodate a large amount of bath water 1 waste water, the bath water 1 purified by the water processor 10 enters the second water tank 12, but the second water tank 12 also has a certain volume, and The volume of the second water tank 12 is less than the first water tank 11, so in order to avoid the second water tank 12 from overflowing, a second water outlet is set on the second water tank 12 and the second water outlet of the second water tank 12 is connected with the third water tank 13, That is, if the second water tank 12 is not enough to accept the waste water imported from the first water tank 11, the second water tank 12 outputs waste water to the third water tank 13 again, that is, the third water tank 13 can be used as a buffer tank for the second water tank 12, so by The second water tank 12 and the third water tank 13 form a structure of a secondary buffer water tank. As shown in Figure 1, temperature sensor 28 and the eighth electromagnetic valve 21 are arranged on the pipeline that the second water outlet of the second water tank 12 is connected with the third water tank 13, the water outlet of the second water tank 12 is connected with the third water tank 13 Also be connected with branch on the pipeline, as shown in Figure 1, be provided with the 9th solenoid valve 22 and the 10th solenoid valve 23 on this branch, this branch is finally connected with waste water tank 7, because the first water tank 11 is used for collecting Bathing water 1, and bathing water 1 usually has a certain residual temperature, especially when bathing in winter, the remaining temperature is relatively high. When the first water tank 11 is full, the water in the first water tank 11 is input to the second water tank 12. When the water in the second water tank 12 is full, the water in the second water tank 12 is input to the third water tank 13, and the third water tank 13 also has a certain volume, it is impossible to accept the waste water imported by the second water tank 12 without limit, so When the third water tank 13 is also full of waste water, the eighth solenoid valve 21 is closed, the ninth solenoid valve 22 and the tenth solenoid valve 23 are opened, and the excess waste water is directly sent to the waste water tank 7, and the waste water tank 7 is connected to the municipal sewage pipe. Connected, that is, excess waste water can be discharged by municipal sewage pipes. The water levels of the above-mentioned first water tank 11, second water tank 12, and third water tank 13 can be detected by setting a water level sensor in the prior art. When the water level sensor reaches the upper limit, it means that the water tank is already full and cannot continue to carry waste water.

For the specific control of the ninth electromagnetic valve 22 and the tenth electromagnetic valve 23, if the detection value of the temperature sensor 28 arranged at the second water outlet of the second water tank 12 is greater than a predetermined threshold value, it indicates that the first water tank 11 is moving toward the second water tank 12. The water temperature of the second water tank 12 input is higher, now open the eighth solenoid valve 21, open the ninth solenoid valve 22, open the tenth solenoid valve 23, then the water in the second water tank 12 flows from the second water outlet to the third water tank 13 Transport, a part of water enters the third water tank 13 for storage, and a part of water passes through the ninth solenoid valve 22 and the tenth solenoid valve 23 and finally enters the waste water tank 7; if the temperature sensor 28 at the second water outlet of the second water tank 12 If the detected value is less than the predetermined threshold, the temperature of the water input from the first water tank 11 to the second water tank 12 is relatively low, and can be directly used for garden water 8 (that is, it can be directly used for garden irrigation water), and the eighth solenoid valve 21 is opened at this time. , open the ninth solenoid valve 22, close the tenth solenoid valve 23, now a part of water enters the third water tank 13 for storage, and another part of water is directly used for garden water 8 after passing through the ninth solenoid valve 22, after the garden water 8 is finished, Open the tenth electromagnetic valve 23 again, now unnecessary waste water enters the waste water tank 7 through the ninth electromagnetic valve 22 and the tenth electromagnetic valve 23. That is to say, it is determined whether the bathing water 1 is used for the garden water 8 according to the temperature of the water output from the second water tank 12 , so as to realize the maximum utilization of waste water.

As shown in Figure 1, the second water tank 12 is connected to the mop pool 6, and the mop pool 6 is connected to the waste water tank 7. The third concentration sensor 27 is set on the pipeline connecting the mop pool 6 to the waste water tank 7, and a third concentration sensor 27 is also arranged on the pipeline. The branch road is directly connected to the garden water 8, the sixth solenoid valve 19 is set on this branch road, and the seventh solenoid valve 20 is set on the pipeline connecting the mop pool 6 to the waste water pool. Above-mentioned setting is in order to make full use of the waste water of mop pond 6, in daily life, when just beginning to wash and rinse mop, waste water is the dirtiest, and the waste water of mop pond 6 at this moment contains pollutants such as a large amount of dust, silt, at this moment Wastewater does not have the value of reuse, so the third concentration sensor 27 is set at the mop pool 6 drains, when the detected value of the third concentration sensor 27 is greater than the predetermined threshold, it shows that the waste water at this time does not have the value of reuse, so The seventh solenoid valve 20 is opened, the sixth solenoid valve 19 is closed, and the waste water in the mop pool 6 directly enters the waste water tank 7 and is further discharged through the municipal sewage pipeline; when the detected value of the third concentration sensor 27 is less than a predetermined threshold, it indicates that The waste water produced by the mop pool 6 is basically the waste water in the later stage of mop rinsing. At this time, the waste water contains less pollutants such as dust and silt, and has certain utilization value. Therefore, the seventh electromagnetic valve 20 is closed at this time, and the sixth electromagnetic valve Solenoid valve 19 is opened, and as shown in Figure 1, the waste water of mop pool 6 is directly supplied to garden water 8, after garden water 8 is satisfied, promptly when needing to irrigate garden again, the 7th solenoid valve 20 opens, the 6th Solenoid valve 19 is closed, and the waste water of mop pond 6 returns to waste water tank 7 and discharges.

As shown in Figure 1, the water outlet of the third water tank 13 is connected to the cleaning equipment 9, because the third water tank 13 is directly connected to the air-conditioning condensate 4, and the air-conditioning condensate 4 is the waste water with the highest cleanliness in the house, so it can be directly used. The cleaning equipment 9 at the location may be a car washing nozzle or other types of car washing equipment, which is not specifically limited in the present invention. As shown in Figure 1, the water outlet of the third water tank 13 is divided into two branches, one branch is connected to the cleaning equipment 9, and one branch is connected to the waste water tank 7, and an eleventh electromagnet is installed on the branch road connected to the waste water tank 7. The valve 24 and the return water of the cleaning equipment 9 are also connected to the waste water tank 7, so that the waste water generated by the cleaning equipment 9 is collected and discharged in a concentrated manner, ensuring the environmental protection of the entire waste water utilization system.

In addition, the present invention also proposes a residential wastewater collection and utilization method based on the above-mentioned residential wastewater collection and utilization system, which includes the following steps, see Figure 2:

S1. Determine the flow direction of the kitchen water 2 and washing machine drainage 3 according to the measured values of the first concentration sensor 25 and the second concentration sensor 26, and determine the connection between the mop pool 6 and the waste water tank 7 according to the measured value of the third concentration sensor 27 ;

S2. Determine the flow direction of the second water outlet of the second water tank 12 according to the measured value of the temperature sensor 28;
