[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a zero-discharge greywater reuse device, including a base 1, a pretreatment mechanism 2 provided on one side of the surface of the base 1, a biological treatment mechanism 3 provided on one side of the surface of the base 1, and a disinfection mechanism 4 provided at one end of the base 1.

[0020] The pretreatment unit 2 includes a first housing 201, an inlet 202, a first connecting pipe 203, a first filter screen 204, a control valve 205, and a grille 206. One end of the base 1 is connected to the first housing 201. An inlet 202 is provided on one side of the surface of the first housing 201. The first connecting pipe 203 is installed at one end of the first housing 201. The first filter screen 204 is installed inside the first housing 201. The control valve 205 is installed on one side of the surface of the inlet 202. The grille 206 is installed inside the inlet 202. Through the arrangement of the first housing 201, inlet 202, first connecting pipe 203, first filter screen 204, control valve 205, and grille 206, when it is necessary to treat and reuse greywater, the greywater is first connected to the inlet 202. 2. Then, open the control valve 205 on the inlet 202. The greywater enters the first tank 201 through the inlet 202. At this time, the grid 206 inside the inlet 202 will perform the first filtration of the particulate matter in the greywater. When the water volume in the first tank 201 rises to the first filter screen 204, the two-layer first filter screen 204 will enter the greywater in the first tank 201 for secondary filtration. When the water level completely overflows the first filter screen 204, turn on the water pump on the first connecting pipe 203 to remove the greywater above the first filter screen 204. At the same time, when it is necessary to clean the first tank 201, the slope plate installed at the bottom of the first tank 201 and the rotating door opened on the side make the cleaning work very convenient, thereby extending the service life of the mechanism.

[0021] Furthermore, two sets of first filter screens 204 are provided. The first filter screens 204 are located below the first connecting pipe 203. Through the arrangement of the first filter screens 204, when the amount of water in the first tank 201 continues to rise, the multi-layer first filter screens 204 can perform secondary filtration on the water in the first tank 201. When the filtration is completed and the water needs to be pumped away for the next process, the first filter screens 204 can effectively protect the first connecting pipe 203 by intercepting particulate matter and preventing particulate matter from entering the first connecting pipe 203.

[0022] Furthermore, the biological treatment unit 3 includes a second chamber 301, an oxygen tank 302, an activated sludge tank 303, a second filter screen 304, and a second connecting pipe 305. The second chamber 301 is fixedly connected to one side of the surface of the base 1, and the oxygen tank 302 is installed at one end of the base 1. The activated sludge tank 303 and the second filter screen 304 are installed inside the second chamber 301, and the second connecting pipe 305 is installed at one end of the second chamber 301. Through the arrangement of the second chamber 301, oxygen tank 302, activated sludge tank 303, second filter screen 304, and second connecting pipe 305, when water enters the second chamber 301 through the first connecting pipe 203, it flows through the second chamber... As the water level in tank 301 rises and completely overflows activated sludge tank 303, oxygen tank 302 is opened to inject oxygen into the second tank 301. In the tank, the water mixes with activated sludge to promote the degradation of organic matter by microorganisms. At this stage, microorganisms use organic matter as a carbon source to grow and reproduce. After the biological reaction, suspended solids and sludge particles in the water are settled to the bottom of the tank. Afterward, when the treated water overflows the second filter screen 304, the water pump in the second connecting pipe 305 is started to pump the water out of the second tank 301. At the same time, when the second tank 301 needs to be cleaned, its structure is the same as that of the first tank 201, and it can also be cleaned quickly.

[0023] Furthermore, the other end of the first connecting pipe 203 is connected to the second housing 301, one end of the oxygen tank 302 is connected to the second housing 301, the second filter screen 304 is set above the activated sludge tank 303, and the second connecting pipe 305 is set above the second filter screen 304. Through the arrangement of the oxygen tank 302, the activated sludge tank 303, and the second filter screen 304, the oxygen tank 302 stores high-pressure oxygen, which allows the oxygen to enter the second housing 301 at a high pressure, thereby promoting the combination and reproduction of organic matter in the water and activated matter in the activated sludge tank 303. At the same time, after treatment, the second filter screen 304 can also intercept particulate matter, preventing particulate matter from entering the second connecting pipe 305 and affecting the operation.

[0024] Furthermore, the disinfection mechanism 4 includes a third housing 401, a motor 402, an inlet 403, a water outlet 404, and a stirring fan 405. The third housing 401 is fixedly connected to one side of the surface of the base 1. The motor 402 is installed at one end of the third housing 401. The inlet 403 is opened on one side of the surface of the third housing 401. The water outlet 404 is installed at one end of the third housing 401. The stirring fan 405 is connected to the other end of the motor 402. Through the arrangement of the third housing 401, motor 402, inlet 403, water outlet 404, and stirring fan 405, when water passes through the second connection... After pipe 305 enters the third tank 401, when the water level in the third tank 401 reaches a certain level, disinfectant is poured into the third tank 401 through inlet 403. Then, motor 402 is started, and motor 402 drives the stirring fan 405 to rotate. The stirring fan 405 thoroughly mixes the greywater and disinfectant in the third tank 401, thus performing the final disinfection of the greywater. After stirring is completed, motor 402 is turned off, and the disinfected water can be extracted through outlet pipe 404 to complete the reuse of greywater. At the same time, the third tank 401 has the same structure as the previous two tanks, which is very convenient for cleaning.

[0025] Furthermore, the stirring fan 405 is installed inside the third tank 401, and the other end of the second connecting pipe 305 is connected to the third tank 401. Through the installation of the stirring fan 405, the stirring fan 405 can fully mix the treated water and disinfectant water in the third tank 401, thereby killing residual microorganisms and ensuring that the water quality meets the standards for reuse.

[0026] Working Principle: When reclaimed water needs to be treated and reused, firstly, the reclaimed water is connected to the inlet 202, and then the control valve 205 on the inlet 202 is opened. The reclaimed water enters the first tank 201 through the inlet 202. At this time, the screen 206 inside the inlet 202 will perform the first filtration of particulate matter in the reclaimed water. When the water level in the first tank 201 rises to the first filter screen 204, the two-layer first filter screen 204 will enter the reclaimed water in the first tank 201 for secondary filtration. When the water level completely overflows the first filter screen 204, the water pump on the first connecting pipe 203 is turned on to remove the reclaimed water above the first filter screen 204 for the next step. When the reclaimed water enters the second tank 301 through the first connecting pipe 203, as the water level in the second tank 301 rises, when the water level completely overflows the activated sludge tank 303, the oxygen tank 302 is turned on to inject oxygen into the second tank 301. In the tank, the reclaimed water and activated sludge react... The mixture of mud and sludge promotes the degradation of organic matter by microorganisms. In this stage, microorganisms use organic matter as a carbon source for growth and reproduction. After the biological reaction, suspended solids and sludge particles in the reclaimed water are settled to the bottom of the tank. After the treated reclaimed water overflows the second filter screen 304, the water pump in the second connecting pipe 305 is started to pump the reclaimed water out of the second tank 301 for the next step. After the reclaimed water enters the third tank 401 through the second connecting pipe 305, when the water volume in the third tank 401 reaches a certain level, disinfectant water is poured into the third tank 401 through the inlet 403. Then, the motor 402 is started, which drives the stirring fan 405 to rotate. The stirring fan 405 fully mixes the reclaimed water and disinfectant water in the third tank 401, thus performing the final disinfection work on the reclaimed water. After the stirring is completed, the motor 402 is turned off, and the disinfected water can be pumped out through the outlet pipe 404. The above completes the reclaimed water reuse treatment.
