Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a device for circulating and purifying building sewage. Background Art

[0002] The building sewage recycling and purification treatment device recycles and utilizes water resources through collection, filtration and biochemical treatment. First, the gray water and black water are separated. The gray water is intercepted by the screen with large particles of impurities and then enters the regulating tank to balance the water quality and water quantity. The black water is initially degraded by organic matter through the septic tank or anaerobic reactor. Subsequently, the biofilm method or activated sludge method is used for deep treatment, combined with disinfection to ensure that the water quality meets the standards. The purified water can be used for flushing toilets, greening or cooling components, reducing fresh water consumption, energy saving and high efficiency, and is suitable for residential and commercial buildings and other scenarios.

[0003] The building sewage recycling purification treatment device adopts a three-zone structure. The anaerobic zone uses anaerobic bacteria to decompose large molecular organic matter, reduce chemical oxygen demand and produce biogas. The aerobic zone promotes aerobic microorganisms to degrade residual pollutants through aeration and remove ammonia nitrogen and phosphorus. After sedimentation, filtration and ultraviolet or chlorine disinfection in the purification treatment area, the water quality meets the reuse standard and can be used for flushing toilets, greening or landscape water replenishment, achieving efficient and energy-saving operation.

[0035] Reference Figure 1 、 Figure 4 and Figure 5 The quick-change assembly includes a diaphragm filter plate 10. The diaphragm filter plate 10 has high-efficiency filtration performance and a long service life, and effectively removes fine particles and impurities in sewage. The diaphragm filter plate 10 is slidably connected to the inside of the purification tank 1, and the diaphragm filter plate 10 moves laterally and smoothly in the purification tank 1. One side of the diaphragm filter plate 10 is fixedly connected to a fixing plate 27, and the fixing plate 27 is fixedly connected to one end of the diaphragm filter plate 10 away from the diaphragm filter plate 10. The blocking block 26 cooperates with the first blocking ring 22 and the second blocking ring 23 to achieve rapid fixing and disassembly of the diaphragm filter plate 10. The outer side of the blocking block 26 is slidably connected to the first blocking ring 22, and the interior of the first blocking ring 22 is provided with a guide groove to guide the blocking block 26 to be accurately inserted. The inner rotation of the first blocking ring 22 is connected to the rotating column 21, and the rotating column 21 provides a rotating support for the first blocking ring 22 and the second blocking ring 23 to enable it to be flexibly opened and closed. The outer side of the rotating column 21 is rotatably connected to the second blocking ring 23, and the second blocking ring 23 cooperates with the blocking block 26 to form a locking structure. In the locked state: the first clamping ring 22 and the second clamping ring 23 surround the clamping block 26. It should be noted that, referring to Figure 5 It can be seen that when the first clamping ring 22 and the second clamping ring 23 are encircling the block 26, there is a blockage at both ends of the block 26 (i.e., the rotating column bracket 29, the rotating column 21 is installed on the fixed plate 20 through the rotating column bracket 29), which is used to prevent the block 26 from axially displacing in the first clamping ring 22 and the second clamping ring 23 in this state.

[0037] Working principle:

[0038] The device for recycling and purifying building sewage purifies and filters domestic sewage and building sewage, and injects the sewage into the sewage pool 6. The sewage pool 6 serves as the starting point of the entire purification process. The anaerobic environment constructed inside provides suitable living conditions for anaerobic biological flora. Microorganisms can decompose large molecular organic pollutants in sewage and convert them into small molecular substances, completing the first round of preliminary treatment of sewage and reducing the subsequent purification pressure. After treatment, the sewage enters the purification pool 1 through the pipe 8. The sewage flow rate can be controlled by quickly closing and opening the device. The motor 2 19 is used to drive one of the gears 2 15 to rotate. The gear 2 15 forms an efficient transmission relationship with the rack 2 14 and the gear ring 18, and at the same time drives the rack 2 14 to move up and down and the gear ring 18 to rotate. The rear end of the partition plate 13 They are all fixedly connected with rack 2 14. As rack 2 14 moves, partition plate 13 rises and falls accordingly in pipe 8. By changing the flow area in pipe 8, sewage flow is precisely adjusted. One of gear 2 15 rotates and drives the ring gear 18 to rotate, and the ring gear 18 drives the other five racks 2 14 to move synchronously. A single motor is used to drive all partition plates 13 to achieve unified opening and closing, which simplifies the control components and reduces the energy consumption of the equipment. In order to protect the components from being blocked by large objects, a filter screen 7 is installed on its outside. The filter screen 7 effectively intercepts branches, gravel, plastic bags and other debris in the sewage to prevent these debris from entering pipe 8 and purification tank 1, and prevents the partition plate 13 from getting stuck, the gears from getting stuck and other faults, providing convenience of use and facilitating flexible control of sewage flow.

[0039] In the purification tank 1, the water quality is deeply purified. The two ends of the partition 11 are respectively divided into an aerobic zone and a water source area to be purified. Sufficient oxygen is provided in the aerobic zone through the aeration device. Aerobic microorganisms further decompose the pollutants in the sewage in this environment, reducing the chemical oxygen demand and biochemical oxygen demand of the sewage. The membrane filter plate 10 set in the last area serves as the last line of defense in the purification process. It uses its special microporous structure to intercept the fine particles, colloidal substances and microorganisms remaining in the sewage to ensure that the effluent water quality meets the discharge standards. During long-term use, the membrane filter plate 10 needs to be replaced due to blockage, breakage, etc. The traditional method requires emptying the pool, which is time-consuming and labor-intensive. For this purpose, a quick replacement component is set. The motor 15 drives the worm 4 to rotate. By meshing with the gear 12, the rotational motion is converted into the linear motion of the rack 9, causing the rack 9 to slide upward. When the entire diaphragm filter plate 10 is exposed to the water surface, the staff can replace it without draining the water. A fixing plate 27 is fixed to one end of the diaphragm filter plate 10. The clamping block 26 at the front end of the fixing plate 27 can be inserted or pulled out from the inner side of the first clamping ring 22 and the second clamping ring 23. Under the cushioning effect of the spring 25, the two can buffer the impact force when the clamping block 26 is inserted. At the same time, the connection and cooperation of the rotating column 21 enable the first clamping ring 22 and the second clamping ring 23 to be flexibly opened and closed, so that the diaphragm filter plate 10 can be quickly replaced, effectively solving the problem of replacing the diaphragm filter plate 10 and significantly reducing the cost, time and energy of emptying the pool.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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 replacements for some of the technical features therein.
