Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater classification and treatment system. Background Technology

[0002] Wastewater treatment refers to the process of separating pollutants from wastewater or converting them into harmless substances, thereby purifying the wastewater. This prevents wastewater from being directly discharged into rivers, lakes, oceans, and other water bodies, avoids water pollution and water quality deterioration, maintains the balance of the aquatic ecosystem, reduces the threat to human health from harmful substances in wastewater (such as pathogens, heavy metals, and toxic organic matter), and prevents diseases caused by drinking water or contact with polluted water. Treated wastewater can be reused in industrial, agricultural, and municipal fields, alleviating water shortage problems.

[0003] Chinese Patent Publication No. CN210559913U discloses a wastewater classification and treatment system, aiming to provide a wastewater classification and treatment system with preliminary filtration effect, simple structure, and strong practicality. It also includes a filter device installed at the inlet. The key technical point is that the filter device includes a filter cylinder installed at the inlet port, multiple layers of filter screens installed inside the filter cylinder, a support component installed between two adjacent filter screens, and a disassembly mechanism installed between the filter cylinder and the inlet port. The disassembly mechanism includes a first retaining ring installed along the periphery of the inlet port, a second retaining ring installed on the periphery of the filter cylinder and abutting against the first retaining ring, and a locking component sequentially connecting the first and second retaining rings. This utility model is applicable to the field of wastewater treatment equipment technology.

[0004] For existing wastewater classification and treatment systems, in actual operation, when wastewater is filtering impurities, it cannot independently access each filter layer. Maintenance requires complete disassembly, which is costly. Uneven water flow distribution can easily form "preferred channels" (such as flow along the filter basket wall), resulting in poor interception of suspended solids. Filter cartridges need to be disassembled and installed vertically, and maintenance of the bottom filter cartridges is difficult. In biological purification, traditional biological purification devices are not equipped with temperature control systems, making it difficult to maintain the baseline temperature of the microbial living environment. At low temperatures (such as in winter), the activity of microorganisms is inhibited, and the purification efficiency is reduced. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater classification and treatment system that solves the problem in the existing technology that uneven water flow distribution and the formation of "preferred channels" during wastewater filtration can easily affect the filtration effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wastewater classification and treatment system includes a filter box, with several support blocks fixedly connected to the inside of the filter box. A support plate is slidably connected between two support blocks at the same height. A conical filter block is fixedly connected inside the support plate, and a filter is slidably connected inside the filter block. An L-shaped jet pipe is installed on the side of the filter box, with one end of the jet pipe connected to a jet generator. An outlet pipe is connected to the side of the filter box, with a purification mechanism at one end. An inlet pipe is connected to the side of the filter box.

[0008] Preferably, the purification mechanism includes a water purification tank connected to the water outlet pipe, and two fixed frames are fixedly connected inside the water purification tank, with carbonized wood assemblies slidably connected inside the fixed frames.

[0009] Preferably, a heater is fixedly connected to the side of the water purification tank, and the heating element of the heater is located inside the water purification tank.

[0010] Preferably, a treatment cylinder is fixedly connected to one side of the water purification tank. The treatment cylinder has a first purification cylinder inside, the first purification cylinder has a second purification cylinder inside, and the second purification cylinder has a drain pipe inside.

[0011] Preferably, the surface of the treatment cylinder has several water inlet holes.

[0012] Preferably, one end of the water inlet pipe is connected to a water inlet tray, which is located directly above the filter.

[0013] This utility model has the following beneficial effects:

[0014] When treating wastewater, the wastewater is first filtered. During the filtration process, pulsed air can be injected into the tank through a jet generator to disturb the water flow and prevent the formation of a "preferred channel" between the filter and the filter block, thus optimizing the filtration efficiency. It also makes it easy to replace the filter from the side of the filter box, facilitating the replacement of the bottom filter. Several filters are independent of each other and can be replaced independently. When the temperature in the purification tank is low, it can be easily heated by a heater to ensure the activity of microorganisms, thereby ensuring the efficiency of wastewater biological purification.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A wastewater classification and treatment system includes a filter box 1, which is a metal box with a metal door on the side for opening and closing. Several support blocks 2 are fixedly connected to the inside of the filter box 1. A support plate 3 is slidably connected between two support blocks 2 at the same height. When wastewater filtration is required, the door of the filter box 1 can be opened first, and then the support plate 3 can be slid onto the support blocks 2, placing the support plate 3 through the two support blocks 2 at the same height. A conical filter block 4 is fixedly connected inside the support plate 3. The conical filter chamber inside the conical filter block 4 promotes the formation of a swirling flow in the water, reducing the risk of short-circuiting of unfiltered water. A filter 5 is slidably connected inside the filter block 4. The filter 5 consists of two vertically distributed filter screens and a filter element fixed in the middle, effectively filtering wastewater. The filter element is generally made of volcanic ash, which has strong anti-clogging ability and is economical. Wastewater enters the filter box 1 from above through the inlet pipe 10. At that time, the sewage can be filtered through the filter 5 inside the filter block 4 and discharged. After the above filtration process is repeated, the impurities inside the sewage will be intercepted by the filter 5, ensuring that the sewage will not be affected by impurities in subsequent purification treatment. An L-shaped jet pipe 6 is installed on the side of the filter box 1. One end of the jet pipe 6 is connected to a jet generator 7. The jet generator 7 can spray air from below through the jet pipe 6. The jet generator 7 injects pulsed air into the box, disturbs the water flow, avoids the formation of a "preferred channel" between the filter 5 and the filter block 4, and optimizes the filtration efficiency. A water outlet pipe 8 is connected to the side of the filter box 1. After filtration, the sewage is discharged through the water outlet pipe 8. A purification mechanism 9 is installed at one end of the water outlet pipe 8. The filtered sewage enters the purification mechanism 9 for purification treatment. A water inlet pipe 10 is connected to the side of the filter box 1. The water inlet pipe 10 discharges the sewage into the filter box 1 from above, so that the sewage can be filtered.

[0024] Furthermore, the purification mechanism 9 includes a water purification tank 901 connected to the water outlet pipe 8. Two fixed brackets 902 are fixedly connected inside the water purification tank 901. Carbonized wood assembly 903 is slidably connected inside the fixed brackets 902. After the water outlet pipe 8 sends all the filtered sewage into the water purification tank 901, the sewage can be purified by the carbonized wood inside the carbonized wood assembly 903. When the carbonized wood assembly 903 needs to be replaced, the fixed brackets 902 can be easily removed from the top, making the replacement of the carbonized wood assembly 903 convenient. Moreover, the replacement of the two carbonized wood assemblies 903 will not affect the purification of sewage. The microorganisms attached to the carbonized wood assembly 903 are the main force for purifying sewage.

[0025] Furthermore, a heater 904 is fixedly connected to the side of the water purification tank 901. The heating tube of the heater 904 is located inside the water purification tank 901. The temperature sensor on the heater 904 monitors the temperature in real time. When the temperature of the water purification tank 901 is lower than the reference value, heating is automatically started. When the temperature exceeds the threshold, heating stops, achieving energy-saving operation. This solves the problem that the activity of microorganisms residing inside the carbonized wood group 903 is inhibited in winter, resulting in reduced purification efficiency. It can ensure the efficiency of sewage purification in winter. The heating tube of the heater 904 can stably heat the sewage inside the purification tank when the temperature is low.

[0026] Furthermore, a treatment cylinder 905 is fixedly connected to one side of the water purification tank 901. Inside the treatment cylinder 905 is a first-layer purification cylinder 906, and inside the first-layer purification cylinder 906 is a second-layer purification cylinder 907. Inside the second-layer purification cylinder 907 is a drain pipe 908. After the sewage is purified by the microorganisms inside the two carbonized wood groups 903, it can pass through the treatment cylinder 905 into the first-layer purification cylinder 906, where it is purified by the smokeless coal or activated carbon inside the first-layer purification cylinder 906. The second-layer purification cylinder 907 is located inside the first-layer purification cylinder 906. The filter elements inside the first-layer purification cylinder 906 and the second-layer purification cylinder 907 are the same, which makes the sewage purification effect better. After passing through the first-layer purification cylinder 906 and the second-layer purification cylinder 907, the sewage enters the drain pipe 908 and is discharged by the drain pipe 908.

[0027] Furthermore, the surface of the treatment cylinder 905 is provided with several water inlet holes 909. When it is necessary to purify and discharge sewage, the sewage can enter the interior of the treatment cylinder 905 through the water inlet holes 909, and then be purified by the first purification cylinder 906 and the second purification cylinder 907, so as to ensure that the purification in the purification tank is completed when the sewage is discharged.

[0028] Furthermore, one end of the inlet pipe 10 is connected to an inlet tray 11, which is located directly above the filter 5. When it is necessary to send sewage into the filter box 1, the sewage can be sent in through the inlet pipe 10, and then the sewage can be sprayed out over a large area through the inlet tray 11 so that it can be evenly immersed into the filter 5 for filtration.

[0029] In summary:

[0030] When wastewater needs to be treated, it must first be filtered to remove impurities and prevent them from affecting subsequent purification. Wastewater enters the filter box 1 through the inlet plate 11 on the inlet pipe 10 and is then evenly sprayed onto the filter 5 for filtration. The filter 5 is located inside the filter block 4, which is placed on two support blocks 2 at the same height by the support plate 3. The wastewater first passes through the filter screen on the filter 5, then is filtered by the filter element, and then discharged through the filter screen. After one pass, it enters the next filter 5 for further filtration. After multiple filtrations, the wastewater is discharged through the outlet. Pipe 8 discharges. During the wastewater filtration process, jet generator 7 can spray air onto filter 5 from below through jet pipe 6. Jet generator 7 injects pulsed air into the chamber, disturbing the water flow and preventing the formation of a "preferred channel" between filter 5 and filter block 4, thus optimizing filtration efficiency. When filter 5 needs to be replaced, the support plate 3 can be removed from support block 2 by opening the door of filter box 1, improving the convenience and efficiency of replacement. Filter 5 can be directly removed from filter block 4 for replacement. After the wastewater leaves through the dewatering pipe, it enters the purification tank. The interior of the purification tank... Biological purification is performed by microorganisms that attach to the interior of the carbonized wood assembly 903. As wastewater passes through, it undergoes biological purification. During microbial purification, when microorganisms are less active in winter, the heater 904 activates to heat the wastewater through heating pipes, thereby increasing microbial activity and ensuring efficient wastewater purification. When the carbonized wood assembly 903 needs replacement, it can be directly removed from the mounting bracket 902. The interior of the carbonized wood assembly 903 is made of carbonized wood, while the exterior is made of wood panels. The wood panels effectively encapsulate the carbonized wood, preventing debris from falling off. For easy replacement and maintenance, after the sewage is purified by microorganisms inside the two carbonized wood groups 903, the sewage enters the first-layer purification tank 906 and the second-layer purification tank 907 through the water inlet 909 on the surface of the treatment tank 905. It is then purified by the first-layer purification tank 906 and the second-layer purification tank 907, and then the purified water is discharged through the drain pipe 908. With the above structure, when sewage treatment is required, it can easily filter impurities in the sewage, and can also purify the sewage through biological purification. Furthermore, when the temperature is low, the temperature can be increased to ensure the activity of microorganisms and thus ensure the purification efficiency.
