[0027] First embodiment
[0028] This embodiment discloses an MBR membrane assembly, referring to Figure 1-3As shown, it includes a chamber 100 for accommodating treatment equipment. Specifically, a partition 110 is provided in the chamber 100, and the partition 110 separates the chamber 100 into a treatment chamber 120 and an equipment chamber 130. An MBR membrane 121 is provided in the treatment chamber 120. In this example, the partition 110 has a certain strength and sealing performance to ensure the functional separation and environmental isolation of the treatment chamber 120 and the equipment chamber 130. A plurality of MBR membranes 121 are installed in the treatment chamber 120 for effectively filtering wastewater and separating solid pollutants. The equipment chamber 130 accommodates treatment equipment, such as pumps, pipelines, and control systems. In addition, the chamber 100 is also provided with pipelines to input water to be treated and output treated water, specifically, including sewage pipes 200200 and active material pipes 300.
[0029] As mentioned above, a sewage pipe 200 and an active material pipe 300 are provided in the chamber 100. Figure 1 As shown, the sewage pipe 200 and the active material pipe 300 are both arranged in the chamber 100 and pass through the partition 110. Specifically, one end of the sewage pipe 200 is connected to an external sewage source for introducing the sewage to be treated into the treatment chamber 120, and the other end leads to the top of the MBR membrane assembly to ensure that the sewage is evenly distributed on the surface of the MBR membrane 121. In some examples, a plurality of nozzles or distribution holes are provided inside the sewage pipe 200 to achieve uniform distribution of sewage. The active material pipe 300 is used to transport active materials (such as chemicals or biologically active substances) for treatment. One end of the pipe is connected to a storage tank 310 for storing active materials, and the other end leads to the inside of the treatment chamber 120. The active material pipe 300 also passes through the partition 110, wherein the partition 110 is provided with a through hole for passing the sewage pipe 200 and the active material pipe 300. In order to ensure the connection and sealing of the sewage pipe 200 and the active material pipe 300, a sealing ring and a fixing clamp are also provided at the through hole to prevent leakage when the pipe passes through the partition 110.
[0030] Second embodiment
[0031] Based on the above embodiments, in this example, the ends of the sewage pipe 200 and the active material pipe 300 are open, and the ends of the sewage pipe 200 and the active material pipe 300 release liquid to the processing chamber 120. Specifically, the part of the sewage pipe 200 located in the equipment chamber 130 is connected to sewage, and the end of the part of the sewage pipe 200 located in the processing chamber 120 is open and faces the MBR membrane 121. When the system is started, the sewage enters the processing chamber 120 through the sewage pipe 200 and is evenly distributed on the surface of the MBR membrane 121 through the nozzle or distribution hole in the sewage pipe 200. The MBR membrane assembly filters the sewage through its microporous structure, and the solid pollutants are trapped on the surface or inside the membrane, while the filtered water flows into the lower part of the processing chamber 120 through the membrane pores. At the same time, the active material (such as chemical agents or biologically active substances) is transported to the processing chamber 120 through the active material pipe 300. In some specific examples, the active material pipe 300 has a plurality of nozzles distributed inside the treatment chamber 120, and these nozzles uniformly release the active material into the sewage in the treatment chamber 120. After the active material is mixed with the sewage, the pollutants in the sewage are further treated through chemical reaction or biological degradation.
[0032] The treated water is discharged through the outlet pipe of the treatment chamber 120, and the trapped solid pollutants are cleaned regularly. The pump and control system in the equipment chamber 130 are responsible for driving and monitoring the entire treatment process, ensuring that the sewage and active materials enter the treatment chamber 120 at the set flow rate and ratio, and monitoring the operating status of the MBR membrane assembly in real time.
[0033] In this example, an auxiliary water reservoir 400 is also connected to the outside of the processing chamber 120, wherein the auxiliary water reservoir 400 is connected to the processing chamber 120 through an auxiliary pipe 410. In the example, the auxiliary water reservoir 400 is a square hollow pool with an opening on the top, and a drainer 420 is provided in the auxiliary pipe 410.
[0034] The drainer 420 is used to drain and / or pump the liquid in the processing chamber 120 into the auxiliary water reservoir 400. For example, the drainer 420 can be an electric pump or a gravity drainage system. In a specific example, the drainer 420 is an electric pump, which is installed on the auxiliary pipe 410. When the liquid in the processing chamber 120 needs to be drained into the auxiliary water reservoir 400, the electric pump is started to pump the liquid into the auxiliary water reservoir 400 through the auxiliary pipe 410. Conversely, when the liquid needs to be drained from the auxiliary water reservoir 400 back to the processing chamber 120, the electric pump runs in reverse. For another example, the drainer 420 is a gravity drainage system, which uses height difference and gravity to achieve liquid discharge and reflux. Specifically, when the liquid level in the processing chamber 120 is higher than that in the auxiliary water reservoir 400, gravity causes the liquid to flow into the auxiliary water reservoir 400 through the auxiliary pipe 410; conversely, when the liquid level in the auxiliary water reservoir 400 is higher than that in the processing chamber 120, the liquid flows back to the processing chamber 120 due to gravity.
[0035] In some preferred embodiments, the auxiliary water reservoir 400 is consistent with the height of the treatment chamber 120, and the auxiliary water reservoir 400 is the same depth as the inside of the treatment chamber 120; it is understandable that the auxiliary water reservoir 400 is consistent with the height and depth of the treatment chamber 120, which can ensure that the liquid level between the two is balanced. When the liquid level in the treatment chamber 120 rises or falls, the liquid can naturally flow between the two through the drainer 420 and the auxiliary pipe 410, thereby maintaining the stable operation of the system. The design of consistent height and depth makes the flow of liquid between the treatment chamber 120 and the auxiliary water reservoir 400 smoother, reduces the resistance and energy loss of liquid flow, and optimizes the efficiency of the system. And by maintaining the balance of the liquid level of the treatment chamber 120 and the auxiliary water reservoir 400, it can ensure that the MBR membrane assembly operates under stable liquid level conditions to avoid the decrease in treatment efficiency due to liquid level fluctuations.
[0036] Third embodiment
[0037] Based on the aforementioned embodiments, in this example, the side wall of the auxiliary water reservoir 400 is connected to the auxiliary pipe 410. In different examples, there are multiple auxiliary pipes 410 between the auxiliary water reservoir 400 and the processing chamber 120, at least part of the auxiliary pipes 410 are located on the side wall of the bottom area of the auxiliary water reservoir 400, and at least part of the auxiliary pipes 410 are located on the side wall of the upper area of the water reservoir.
[0038] Auxiliary pipes 410 are provided above and below the auxiliary water reservoir 400, wherein the upper auxiliary pipe 410 is used to pass the liquid in the processing chamber 120 into the auxiliary water reservoir 400, and the lower auxiliary pipe 410 is used to pass the liquid in the auxiliary water reservoir 400 into the processing chamber 120. This effectively prevents the sewage and impurities from being deposited in the processing chamber 120, thereby improving the processing efficiency. Specifically, the liquid is driven relatively by the upper and lower drainers 420, so that a circulation is formed inside the processing chamber 120, and the auxiliary pipe 410 provided below is used to remove the sewage and impurities at the bottom of the processing chamber 120 to prevent them from accumulating at the bottom of the chamber.
[0039] Fourth embodiment
[0040] Based on the above embodiments, reference Figure 1 and 3 As shown, the auxiliary pipeline 410 includes two water inlet pipelines 411 arranged on the side wall of the upper area of the water reservoir, and a water outlet pipeline arranged on the side wall of the bottom area of the water reservoir (not shown due to obstruction). Figure 3 ).
[0041] Specifically, the two water inlet pipes 411 disposed on the side wall of the upper area of the water reservoir are respectively located on the left and right walls of the upper area of the water reservoir. The ends of the water inlet pipes 411 pass through the partition 110 of the processing chamber 120 through the through hole and are connected to the inside of the processing chamber 120. The water outlet pipe disposed on the side wall of the bottom area of the water reservoir is located on the central side wall of the bottom area of the water reservoir.
[0042] refer to Figure 3 For understanding, in the example, the drainer 420 includes: a first drainer 421, the first drainer 421 is arranged on the water outlet pipe, and the first drainer 421 discharges the liquid from the auxiliary water reservoir 400 to the processing chamber 120; a second drainer 422, the second drainer 422 is arranged on the water inlet pipe 411, and the second drainer 422 discharges the liquid from the processing chamber 120 to the auxiliary water reservoir 400.
[0043] Based on the above embodiments, combined with Figure 1-2 It is understood that the sewage pipe 200 located in the equipment compartment 130 extends into a plurality of sub-sewage pipes 210 , and the sub-sewage pipes 210 are bent and extended to the outside of the equipment compartment 130 .
[0044] In some cases, each of the sub-sewage pipes 210 is externally connected to a different sewage source, such as factory sewage, sewer sewage, etc. In different cases, the sub-sewage pipes 210 are connected to different sewage to achieve simultaneous treatment of multiple sewage.
[0045] Fifth embodiment
[0046] Based on the above embodiments, the structure reference in this example Figure 4 It is understood that the MBR membrane 121 is arranged in a bracket 500 , and the bracket 500 is a cubic frame, and the bracket 500 is fixed in the processing chamber 120 ; wherein, the outlet ends of the sewage pipes 200 are all located above the bracket 500 .
[0047] By introducing sewage from above and cooperating with the drainer 420 on the side, the impurities in the sewage can always be circulated in the treatment chamber 120, achieving a more efficient filtering and treatment effect. Specifically, when the sewage enters the treatment chamber 120 from the outlet end of the sewage pipe 200, since the outlet end of the sewage pipe 200 is located above the bracket 500, the sewage will flow through the MBR membrane assembly from top to bottom. The advantage of this design is that most of the suspended particles and impurities in the sewage will be intercepted by the microporous structure on the surface of the MBR membrane 121, and only the treated clean water can enter the lower part of the treatment chamber 120 through the membrane pores.
[0048] The drainer 420 on the side is responsible for discharging the treated clean water from the processing chamber 120. The liquid inside the processing chamber 120 forms a dynamic flow system under the combined action of water inlet and water outlet, so that the sewage and impurities always circulate in the processing chamber 120, avoiding the accumulation of impurities at the bottom of the processing chamber 120.
[0049] The upper drainer 420 is arranged in the upper area of the treatment chamber 120, near the inlet end of the sewage pipe 200, and is used to guide the liquid in the treatment chamber 120 into the auxiliary water storage tank 400. The upper drainer 420 mainly prevents excessive liquid from accumulating in the upper part of the treatment chamber 120 when the sewage flows through the MBR membrane 121, thereby affecting the filtering effect. The lower drainer 420 is arranged in the bottom area of the treatment chamber 120, and is used to discharge the liquid at the bottom of the treatment chamber 120 into the auxiliary water storage tank 400.
[0050] In some preferred examples, the active material tube 300 extends into the bracket 500, and the role of the active material tube 300 inserted into the bracket 500 is to further optimize the sewage treatment process. Specifically, the active material tube 300 can accurately deliver active materials (such as chemicals or biologically active substances) to the sewage around the MBR membrane assembly through the arrangement inside the bracket 500. This arrangement ensures that the active material is fully mixed with the sewage, thereby effectively enhancing the removal efficiency of organic matter in the sewage during the filtration process of the MBR membrane 121. The addition of active materials can further reduce harmful substances in sewage through chemical reactions or biodegradation, and improve the purification effect of the treated water quality. Therefore, the active material tube 300 inside the bracket 500 can form a complete sewage treatment environment in the treatment chamber 120, thereby ensuring the stable operation and efficient operation of the MBR membrane assembly.
[0051] In some preferred examples, a filter screen 510 is provided between the outlet end of the sewage pipe 200 and the bracket 500 to reduce impurities in the processing chamber 120 .
