Description

Technical Field

[0001] This utility model relates to the field of membrane treatment device technology, specifically a membrane treatment device for reclaimed water reuse. Background Technology

[0002] A membrane treatment device is a device used to treat liquids. Its core component is a membrane. This device utilizes the specific properties of the membrane, such as pore size, material, and charge, to achieve selective separation of different components in the liquid. Membrane treatment devices are widely used in various industrial, municipal, and environmental fields to treat wastewater, drinking water, process water, etc., to achieve the purification, concentration, or recycling of liquids.

[0003] When existing membrane treatment devices filter and purify wastewater, pollutants such as grease and large particles in the wastewater will continuously accumulate on the surface of the membrane module or enter the interior of the membrane module, causing the membrane module to become fouled. Long-term accumulation of pollutants will also clog the membrane pores, affecting the membrane's permeability. This will not only reduce the treatment efficiency of the membrane module but also damage the membrane module and affect its service life.

[0004] Announcement No. CN219823768U discloses a floating oil collection device for kitchen wastewater, including a treatment tank with a wastewater tank and an oil tank. A filter box is fixedly installed on one side of the treatment tank. The floating oil collection device body is placed in the wastewater tank. The floating oil collection device body includes an oil inlet pipe with a fixing ring fixedly installed on its surface. The fixing ring has evenly distributed floats fixedly installed on its surface. With the cooperation of the four floats, the oil inlet pipe always floats on the surface of the wastewater. Under the action of the pump, the floating oil is sucked into the oil inlet pipe. The oil in the oil inlet pipe enters the oil tank through the connecting pipe and the discharge pipe. The collected floating oil is discharged into the collection bucket for storage through the discharge pipe. The floating oil collection device body collects the floating oil in the kitchen wastewater.

[0005] This existing technology does not use membrane filtration components for sterilization filtration.

[0006] Announcement No. CN221971360U discloses an integrated MBR membrane tank system, including a shell, a tank body inside the shell, a limiting plate and an MBR membrane body inside the tank body, the MBR membrane body being located between the limiting plates and slidably connected to the limiting plates; limiting grooves are formed on both sides of the MBR membrane body, and limiting blocks are slidably connected inside the limiting grooves; a moving rod is fixedly connected to the side of the limiting block away from the MBR membrane body, a suspension hole is formed on the side end face of the moving rod, and sliders are fixedly connected to both the front and rear sides of the moving rod; a transmission rod is rotatably connected to the end of the slider away from the MBR membrane body through a connecting shaft, and a positioning rod is rotatably connected to the end of the transmission rod away from the slider; positioning holes corresponding to the positioning rods are formed on the surface of the limiting plate.

[0007] The existing MBR membrane body is relatively cumbersome to operate, and when the liquid flow rate is large, the liquid will pass directly over the MBR membrane body, failing to achieve the filtering function.

[0008] Announcement No. CN221626014U discloses an integrated PP wastewater treatment filtration device. Through a connecting mechanism, a limiting block slides into a limiting groove, connecting the block to an MBR membrane. When cleaning the wastewater inside the wastewater treatment tank, a water pump is started, drawing the wastewater out through a water pipe and inlet. Solid-liquid separation using the MBR membrane separates suspended solids, colloids, and microorganisms lost from the biological unit from the purified water. The treated wastewater is then discharged through a drain pipe, completing the wastewater treatment process. For prolonged wastewater treatment, the MBR membrane needs replacement. Removing the limiting block from the limiting groove allows the MBR membrane to be removed from the wastewater treatment tank, thus completing the replacement.

[0009] The existing MBR membrane technology is relatively cumbersome to operate, and when the liquid flow rate is large, the liquid will pass directly through the space between the MBR membrane and the side shell, thus failing to achieve the filtering function.

[0010] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

[0083] Example 3:

[0084] Based on Example 2, this example provides a method for using a membrane treatment device for greywater reuse, including the following steps:

[0085] S1. The user injects sewage into the treatment tank 102 through the inlet 105. The sewage will cause the float 118 to rise, causing the oil collection seat 117 to move upward along the guide column 116. The grease on the surface of the sewage will continuously enter the oil collection seat 117.

[0086] S2. After the oil pump 104 starts, the oil in the sewage is pumped to the outside through the oil extraction pipe 119 to prevent the oil film from adhering to the surface of the membrane module and affecting the filtration effect of the membrane module. Then, the user can inject the treatment solution into the sewage through the inlet 107 to remove harmful substances inside the sewage.

[0087] S3. Wastewater moves from the inlet area to the outlet area. The filter screen 114 filters out larger impurities in the wastewater, and the germicidal lamp 115 kills bacteria and viruses in the wastewater with ultraviolet light.

[0088] When a large amount of contaminants accumulate on the surface of the filter screen 114, affecting the filtration effect, the cylinder 111 drives the cleaning brush 113 through the piston rod 112 to remove the contaminants from the surface of the filter screen 114.

[0089] S4. After the sewage treatment is completed, the water pump 109 will draw the sewage out of the outlet area of ​​the treatment tank 102 through the water pipe 108 and the water pipe 110, and the sewage will enter the filter tank 201.

[0090] S5. After the sewage enters the filter box 201, it will be filtered by three filter membranes 208 to remove harmful substances as it moves forward. The aeration disc 211 can continuously supply oxygen into the filter box 201, so that the sewage and oxygen are fully mixed, which improves the efficiency and quality of sewage treatment.

[0091] S6. The filtered wastewater arrives at the tail end of the filter box 201. At this time, the water quality detector 212 detects the water quality of the treated water. When the water quality detector 212 detects that the water quality of the treated water is poor, it will start the second water pump 204. The second water pump 204 will bring the treated water to the front end of the filter box 201 for secondary filtration through the third water pipe 203 and the fourth water pipe 205. After the water quality detector 212 detects that the treated water is qualified, it will discharge it by opening the water outlet valve on the second water outlet 202, thereby significantly improving the water quality of the effluent.

[0092] When the filter membrane 208 is damaged, the user can unscrew the fixing screw 209 to remove the filter membrane 208 for replacement or repair, which helps to reduce the time and cost of equipment replacement.
