Description

Technical Field

[0001] The utility model relates to the field of grey water treatment equipment, in particular to an energy-saving grey water treatment system. Background Art

[0002] In order to solve the difficulties of mixed domestic sewage, such as difficult treatment, high treatment costs, and inability to be used for organic farming, we adopt a model of classified collection and treatment of domestic sewage, and collect sewage according to black water and gray water. The black water is treated by fertilizer and the gray water is treated by purification. The carbon-nitrogen ratio of the classified gray water is insufficient. The traditional treatment technology and process is not only energy-intensive but also ineffective.

[0003] For the CRI permeation system, the water entering the system for treatment cannot contain a large amount of impurities. If it contains a large amount of impurities, it is easy to cause the capillary tubes in the CRI system to be blocked. At present, when pre-treating the front water, most of them will use a large number of energy-consuming equipment, and at worst, a large number of pumps are needed to realize the flow of liquid, which is not conducive to energy-saving production. Utility Model Content

[0004] The utility model aims to provide an energy-saving grey water treatment system to solve the problem of high energy consumption in the prior art treatment of the front water entering the CRI system.

[0005] In order to solve the above problems, the utility model adopts the following technical means:

[0006] An energy-saving grey water treatment system, comprising:

[0007] A mud sedimentation tank is constructed with a sedimentation part and an overflow part, wherein the sedimentation part is used to precipitate mud, and the overflow part is used to collect the first treated water after sedimentation;

[0008] A biological filtration mechanism, used for biologically filtering the first treated water and outputting second treated water;

[0009] The CRI treatment system and the UV treatment system, which are connected in sequence, perform post-treatment on the second treated water in sequence, output finished water, and collect it in a water storage tank;

[0010] The overflow portion is connected to the water inlet end of the biological filtration mechanism through a siphon elbow;

[0011] The water outlet of the biological filtration mechanism is in communication with the water inlet of the CRI treatment system;

[0012] The bottom surface of the overflow portion is arranged at a horizontal plane above the top surface of the biological filtering mechanism.

[0013] Preferably, the mud sedimentation tank includes a sedimentation tank body, in which a vertical overflow plate is provided, and the overflow plate divides the sedimentation tank body into a sedimentation chamber serving as the sedimentation part and an overflow chamber serving as the overflow part, and the water inlet end of the siphon bend is connected to the overflow chamber.

[0014] Furthermore, the bottom surface of the mud settling chamber is set as a conical structure, the tip of the conical structure is connected to a first mud discharge pipe, the bottom surface of the overflow chamber is set as a plane structure, and the water inlet end of the siphon bend is arranged close to the bottom surface of the overflow chamber.

[0015] Furthermore, the siphon bend includes a vertical water inlet section, a horizontal water flow section and a vertical water outlet section which are connected in sequence, the pipe mouth of the vertical water outlet section is arranged on the horizontal plane below the vertical water inlet section, and the horizontal water flow section is arranged as the top of the siphon bend.

[0016] Furthermore, the biological filtration mechanism includes a first biological treatment tank and a second biological treatment tank;

[0017] The siphon bend includes a first pipe for connecting the sludge settling tank with the first biological treatment tank, and a second pipe for connecting the first biological treatment tank with the second biological treatment tank. The first biological treatment tank is arranged on a horizontal plane above the second biological treatment tank, and the second biological treatment tank is used to output the second treated water.

[0018] Furthermore, the first biological treatment tank is filled with a first filter element, and the water outlet end of the first pipe and the water inlet end of the second pipe are both buried in the first filter element;

[0019] A diverter plate is provided in the second biological treatment tank, and the diverter plate divides the second biological treatment tank into a treatment chamber and a buffer chamber. The treatment chamber is filled with a second filter element. The water outlet end of the second pipe is buried in the second filter element. The buffer chamber is connected to the water inlet end of the CRI treatment system, and the buffer chamber is used to output the second treated water.

[0020] During use, the utility model has the following beneficial effects:

[0021] Gray water containing silt and other pollutants is precipitated in the mud sedimentation tank. The first treated water output has already precipitated a large amount of large pollutants. The first treated water enters the biological filtration mechanism for purification. After filtering a large amount of suspended pollutants, the second treated water is output, and then the second treated water is passed through the CRI treatment system and the ultraviolet treatment system in turn to form reclaimed water, which is collected in the water storage tank for reuse. In addition, in the process before the sewage enters the CRI treatment system, the connection between different treatment tanks is carried out through the siphon elbow for liquid transfer, which directly reduces the energy consumption caused by setting up a pump for replacing the treatment tank.

[0022] This reduces the traditional high-energy consumption processing equipment, lowers user costs, and can also effectively solve the capillary blockage problem of the CRI processing system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Please refer to Figure 1 As shown, an energy-saving grey water treatment system comprises:

[0032] The mud sedimentation tank 1 is constructed with a sedimentation part and an overflow part, wherein the sedimentation part is used to precipitate the mud, and the overflow part is used to collect the first treated water after sedimentation;

[0033] The biological filtering mechanism 2 is used to perform biological filtering on the first treated water and output second treated water;

[0034] The CRI treatment system 3 and the UV treatment system 4, which are connected in sequence, perform post-treatment on the second treated water in sequence, output finished water, and collect it in the water storage tank 5;

[0035] The overflow portion is connected to the water inlet end of the biological filtration mechanism 2 through a siphon elbow 6;

[0036] The water outlet of the biological filtration mechanism 2 is connected to the water inlet of the CRI treatment system 3;

[0037] The bottom surface of the overflow portion is arranged at a horizontal plane above the top surface of the biological filtering mechanism 2 .

[0038] In this way, the gray water containing sludge and other pollutants is precipitated through the mud sedimentation tank 1. The output first treated water has precipitated a large amount of large pollutants. The first treated water enters the biological filtration mechanism 2 for purification treatment. After filtering a large amount of suspended pollutants, the second treated water is output, and then the second treated water is passed through the CRI treatment system 3 and the ultraviolet treatment system 4 in sequence to form reclaimed water, which is collected in the water storage tank 5 for reuse. In addition, in the process before the sewage enters the CRI treatment system 3, the connection between different treatment tanks is carried out through the siphon elbow 6 for liquid transfer, thereby directly reducing the energy consumption caused by setting up a water pump due to the replacement of the treatment tank.

[0039] This reduces the traditional high-energy consumption processing equipment, reduces the user's cost of use, and can also effectively solve the capillary blockage problem of the CRI processing system 3.

[0040] Furthermore, the mud sedimentation tank 1 includes a sedimentation tank body, in which a vertical overflow plate 7 is provided. The overflow plate 7 divides the sedimentation tank body into a sedimentation chamber 8 as the sedimentation part and an overflow chamber 9 as the overflow part. The water inlet end of the siphon bend 6 is connected to the overflow chamber 9.

[0041] In this way, the sewage entering the mud settling tank 1 is first precipitated in the sedimentation chamber 8, and the upper clear liquid flows into the overflow chamber 9 from above the overflow plate 7 as the liquid level in the sedimentation chamber 8 increases. This ensures that the water sucked in by the siphon bend 6 is the first treated water after sedimentation, and at the same time avoids the siphon bend 6 from being directly connected to the sedimentation chamber, causing violent liquid disturbance in the sedimentation chamber and affecting the sedimentation effect.

[0042] Furthermore, the bottom surface of the mud sedimentation chamber 8 is set as a conical structure, the tip of the conical structure is connected to the first mud discharge pipe 10, the bottom surface of the overflow chamber 9 is set as a plane structure, and the water inlet end of the siphon bend 6 is arranged close to the bottom surface of the overflow chamber 9.

[0043] Thus, the conical structure is used to facilitate the efficiency of using the first mud discharge pipe 10 to discharge mud. The accumulation of mud and dirt at the bottom of the sedimentation chamber 8 during the mud discharge process is reduced. And the overflow chamber 9 is set as a flat structure, which can make the siphon elbow 6 better when absorbing water.

[0044] At the same time, for the siphon bend 6, the siphon bend 6 includes a vertical water inlet section 11, a horizontal water flow section 12 and a vertical water outlet section 13 which are connected in sequence, the pipe mouth of the vertical water outlet section 13 is arranged on the horizontal plane below the vertical water inlet section 11, and the horizontal water flow section 12 is arranged as the top of the siphon bend 6.

[0045] In this way, when the liquid level on one side of the siphon elbow 6 exceeds the horizontal water flow section 12, the siphon is completely connected. Under the action of the siphon, the liquid on the side with a high liquid level continuously enters the liquid side with a low liquid level.

[0046] Furthermore, the biological filtration mechanism 2 includes a first biological treatment tank 14 and a second biological treatment tank 15;

[0047] The siphon bend 6 includes a first pipe for connecting the sludge settling tank 1 with the first biological treatment tank 14, and a second pipe for connecting the first biological treatment tank 14 with the second biological treatment tank 15. The first biological treatment tank 14 is arranged on a horizontal plane above the second biological treatment tank 15, and the second biological treatment tank 15 is used to output the second treated water.

[0048] In order to make the output second treated water output more concentrated, the first biological treatment tank 14 is filled with a first filter element 16, and the water outlet end of the first pipe and the water inlet end of the second pipe are both buried in the first filter element 16;

[0049] A diverter plate 17 is provided in the second biological treatment tank 15, and the diverter plate 17 divides the second biological treatment tank 15 into a treatment chamber 18 and a buffer chamber 19. The treatment chamber 18 is filled with a second filter element 20. The water outlet end of the second pipe is buried in the second filter element 20. The buffer chamber 19 is connected to the water inlet end of the CRI treatment system 3, and the buffer chamber 19 is used to output the second treated water.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
