Description

Technical Field

[0001] The present invention belongs to the technical field of water resource recycling and utilization, and in particular relates to a water resource optimization configuration system and method. Background Art

[0002] Water is an indispensable resource in people's lives, but nowadays water resources are becoming increasingly scarce. According to incomplete statistics, there are still more than 1 billion people in the world who do not have access to clean water. Every year, about 3.1 million people die from diseases caused by drinking unclean water. Humanity is facing a global water shortage. The 47th United Nations General Assembly designated March 22 as World Water Day. According to survey statistics, the average daily flushing volume of flush toilets used by urban (town) residents in my country is about 30 to 50L. Based on a population of 750 million, my country loses as much as 30 million tons of tap water every day (the water storage capacity of West Lake is 14 million tons), which does not include the tap water consumed by some rural populations who have started using flush toilets. Therefore, it is crucial to optimize the allocation of water resources and save water.

[0003] For example, the Chinese patent application number (CN201610172300.7) discloses a water-saving system for buildings. The patent recycles rainwater and grey water and then uses them for bathroom water. It also mentions that they can be used for landscaping, sprinkler trucks, car washing, emergency fire-fighting water, and cleaning corridors and stairs, etc. However, the application does not process the rainwater and grey water after recycling them, and directly uses them for bathroom water, greening, and cleaning corridors and stairs, which poses a safety hazard and can easily lead to the spread of pathogens and cause environmental pollution (such as odor). Therefore, when recycling rainwater and grey water, they need to be processed. Summary of the Invention

[0113] The second storage unit 7 in the podium 11 and in the main building 10 not higher than the podium 11 is connected to the greening irrigation unit 3 and the cleaning water unit 2 on each floor, while the second storage unit 7 in the main building 10 higher than the podium 11 is connected to the first treatment unit 4;

[0114] Meanwhile, the third processing unit 8 can be arranged at the back of the canteen 12 by connecting the drain pipe 13 of the vegetable washing sink to the third processing unit 8;

[0115] A three-way joint is provided at one end of the downpipe 13 close to the second water collecting tank 80 for draining rainwater when the rainfall is too heavy to avoid exceeding the maximum water storage capacity of the second water collecting tank 80.

[0116] It can be seen from this embodiment that by utilizing the roof of the 10th floor of the main building, this part of the recycled water is supplied through the height difference of the floors, which meets the supply of recycled water to high floors without electricity consumption, saving operating costs. At the same time, rainwater collection is set on the roof of the 11th floor of the podium, and the space on the roof of the 11th floor of the podium is reasonably utilized, reducing the occupation of space such as ground or underground garages.

[0117] Example 5:

[0118] This embodiment provides a water resource optimization allocation system. In addition to the technical solutions of the above embodiments, it also has the following technical features: the first processing unit 4 includes:

[0119] A rain collecting cover 40 is used to collect rainwater;

[0120] The filter assembly 41 is connected to the bottom of the rain collecting cover 40 and is used for processing rainwater and kitchen water;

[0126] Example 6:

[0127] This embodiment provides a water resource optimization allocation system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The filter component 41 includes:

[0128] The housing 410 is installed below the rain collecting cover 40;

[0129] The filter cartridge 411 is installed in the housing 410 and is arranged horizontally. A plurality of filter holes are opened on the surface of the filter cartridge 411.

[0130] A driving device 412 is installed on one side of the filter cartridge 411 and is used to rotate the filter cartridge 411;

[0131] A water tank 413 is installed below the housing 410 and is used for temporarily storing filtered rainwater and kitchen water;

[0132] A first scraper device 414 is installed on the side of the filter cartridge 411 and is used to clean the surface of the filter cartridge 411;

[0133] The collecting box 415 is installed on the side of the water tank 413 and is located corresponding to the first scraping device 414;

[0134] The water tank 413 is connected to the collection tank 42 via a first water pump 44 , and an overflow port 416 is provided on a side of the housing 410 away from the first scraping device 414 ;

[0135] At the same time, the width dimension of the shell 410 along the radial direction of the filter cylinder 411 is smaller than the diameter dimension of the filter cylinder 411, ensuring that rainwater always keeps in contact with the filter cylinder 411 after entering the shell 410, thereby ensuring the filtration of rainwater; and the first scraper device 414 includes a pressure roller and a scraper, the scraper abuts against the side of the filter cylinder 411 and is set at the same height as the axis of the filter cylinder 411, and the other side of the scraper is connected to a U-shaped chute, and the U-shaped chute extends into the collection box 415, and the surface of the pressure roller is made of elastic material, which can be made of rubber, to avoid jamming caused by harder impurities such as stones falling into.

[0136] It can be seen from this embodiment that by adopting the rotating filter cartridge 411, the filter cartridge 411 has a better double-layer filtering effect on rainwater, and the first scraper device 414 is convenient for cleaning the surface of the filter cartridge 411, preventing the filtered impurities from adhering to the surface of the filter cartridge 411, ensuring the filtering efficiency, and at the same time preventing the impurities from being washed into the water tank 413 after the filter cartridge 411 rotates, thereby losing the filtering effect, and the collection box 415 is convenient for collecting the filtered impurities; and by providing a pressure roller, the rotation stability of the filter cartridge 411 can be improved, and the impurities can be crushed and squeezed to prevent water from entering the collection box 415, thereby increasing the total amount of impurities collected by the collection box 415 and extending the maintenance cycle of the collection box 415;

[0137] At the same time, an overflow port 416 is opened, so that when the rainfall per unit time is large and the filtering efficiency of the filter cartridge 411 cannot keep up, the rainwater can be discharged through the sewer pipe 13 to avoid affecting the filtering effect of the filter cartridge 411; at the same time, in actual use, on rainy days, and when the first storage unit 5 and the second storage unit 7 are sufficient, the first water pump 44 can be turned off, that is, the collection of rainwater is stopped, and excess rainwater is discharged through the overflow port, the water tank 413 and the sewer pipe 13.

[0138] Example 7:

[0139] This embodiment provides a water resource optimization allocation system. In addition to the technical solutions of the above embodiments, it also has the following technical features. The filter component 41 also includes:

[0140] A second scraping device 417 is installed in the filter cartridge 411 and is used to clean the inner wall of the filter cartridge 411;

[0141] The second scraping device 417 includes:

[0142] The main shaft 4170 is coaxially mounted in the filter cartridge 411 , with both ends extending out of the filter cartridge 411 and driven by the driving device 412 ;

[0143] Support rods 4171, there are multiple support rods 4171, and they are installed on the main shaft 4170 at equal intervals around the circumference;

[0144] There are multiple scraper rods 4172, each of which is mounted on one end of the multiple support rods 4171 away from the main shaft 4170 and connected to the support rods 4171 via a first ratchet member 4173;

[0145] Among them, the first ratchet member 4173 includes a ratchet and a pawl, and during the rotation of the filter cartridge 411, the scraper rod 4172 can rotate, that is, the ratchet and the pawl are not engaged at this time. At the same time, when the driving device 412 is driven forward, the filter cartridge 411 rotates and the main shaft 4170 does not rotate. When the driving device 412 is driven reversely, the filter cartridge 411 does not rotate, and the main shaft 4170 rotates.

[0146] It can be seen from this embodiment that the second scraper device 417 facilitates the cleaning of the inside of the filter cartridge 411, and cleans a part of the impurities accumulated in the filter cartridge 411 through the filter holes, thereby ensuring the filtering effect. The first ratchet member 4173 between the scraper rod 4172 and the support rod 4171 allows the filter cartridge 411 to rotate when the driving device 412 is driven in the forward direction, while the main shaft 4170 does not rotate, and the scraper rod 4172 is in a rotating state, which facilitates the rotation of the filter cartridge 411. At the same time, the support rod 4171 also improves the stability of the filter cartridge 411 during rotation, thereby ensuring the filtering effect. When the driving device 412 is driven in the reverse direction, the filter cartridge 411 does not rotate, while the main shaft 4170 rotates, and the scraper rod 4172 is stuck under the action of the first ratchet member 4173, which can have a good scraping effect on the inner wall of the filter cartridge 411, thereby ensuring the cleaning of the inner wall of the filter cartridge 411.
