Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an emergency leachate sewage treatment device. Background Art

[0002] Leachate is a liquid with high concentration of organic or inorganic components produced during the garbage stacking and landfill process due to biochemical degradation such as compaction and fermentation, as well as the seepage of precipitation and groundwater. The water quality of leachate is complex and contains a variety of toxic and harmful inorganic and organic substances, such as non-chlorinated aromatic compounds such as naphthalene and phenanthrene that are difficult to biodegrade, phosphate esters, phenolic compounds and aniline compounds.

[0003] If the liquid is not treated in time, a large amount of harmful substances will be produced. The current equipment cannot treat the liquid well, resulting in a large amount of organic matter and large suspended particles in the sewage entering the filtration system, causing organic pollution to the microfiltration membrane and even causing equipment damage. Utility Model Content

[0004] The purpose of the utility model is to provide an emergency leachate sewage treatment equipment, in which the leachate raw water is mixed with a coagulant in a funnel one to complete the sedimentation. Then, due to the start-up of the motor, the rotating column two rotates while driving the transfer column to move synchronously. The leachate impurities from the flocculated supernatant are pumped out and fall onto the mesh transmission belt through the rotation of the transfer column, thus solving the problem that a large amount of impurities and particles in the existing sewage enter the filtration system, causing organic pollution to the microfiltration membrane and even causing damage to the equipment.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an emergency leachate sewage treatment equipment, including a box body, a top cover fixedly connected to the top of the box body, a water pump fixedly connected to the top of the top cover, a suction pipe fixedly connected to the left output end of the water pump, a support leg one fixedly connected to the four corners of the bottom of the box body, a water pipe fixedly connected to the right side of the water pump, a funnel one fixedly connected to the bottom of the top cover, a motor fixedly connected to the back of the box body, a rotating column two rotatably connected to the front of the inner wall of the box body, the bottom of the funnel one contacts with a material transfer column, a notch is provided at the bottom of the material transfer column, and the material transfer column is provided with a notch. A transmission block 2 is fixedly connected to the back of the column, and a mesh transmission belt is transmission-connected to the outer surface of the rotating column 2. The utility model sets a material transfer column, specifically, the leachate raw water is mixed with a coagulant in a funnel 1, and the coagulation and sedimentation can remove part of the organic matter and large suspended particles. After the sedimentation is completed, the rotating column 2 is rotated due to the start of the motor, and the material transfer column is driven to move synchronously. The leachate impurities that are extracted from the flocculation supernatant will fall onto the mesh transmission belt through the rotation of the material transfer column, which effectively slows down the organic pollution of organic matter and large suspended particles entering the subsequent microfiltration membrane.

Due to the action of the spring, the pressure plate can squeeze the trace water contained in the sediment to flow down from the mesh transmission belt, and the excess impurities will be discharged through the slag outlet, so as to effectively circulate and filter the leachate raw water, thereby improving the working efficiency of the equipment.

[0010] Furthermore, a filter box is fixedly connected to the bottom of the water pipe, and an MBR membrane is fixedly connected to the inner wall of the filter box. The number of the MBR membranes is several, and the several MBR membranes are arranged in a vertical array. The MBR membrane can effectively intercept colloids and remove hydrogen sulfide as a microfiltration treatment unit, and can solve the problem of two-stage membrane colloid contamination of membrane components and even blockage of flow channels and sulfur pollution.

[0011] Furthermore, two supporting legs are fixedly connected to the four corners of the bottom of the filter box, and a water outlet is opened on the right side of the filter box. The setting of the supporting legs makes the overall operation of the device more stable without vibration, so that the sedimentation effect is better.

The back side is fixedly connected with a transmission block 231, and the outer surface of the rotating column 2 35 is connected with a mesh transmission belt 211. The utility model sets a material transfer column 34, specifically, the leachate raw water is mixed with the coagulant in the funnel 1 32, and the coagulation precipitation can remove part of the organic matter and large suspended particles. After the precipitation is completed, the rotating column 2 35 is rotated due to the start of the motor 2, and the material transfer column 34 is driven to move synchronously. The leachate impurities of the flocculation supernatant are pumped out and fall onto the mesh transmission belt 211 through the rotation of the material transfer column 34, which effectively slows down the organic pollution of organic matter and large suspended particles entering the subsequent microfiltration membrane.

[0026] The front output end of the motor 2 is fixedly connected with a rotating column 21, which is connected to the rotating column 2 35 through a mesh transmission belt 211. The back of the rotating column 2 35 is fixedly connected with a transmission block 22, and the outer surface of the transmission block 22 is connected to a belt 23, which is connected to the transmission block 2 231 through the belt 23.

[0027] A water inlet pipe 31 is fixedly connected to the top of the top cover 11 , a material inlet 3 is fixedly connected to the center of the top of the top cover 11 , a second funnel 36 is fixedly connected to the bottom of the inner wall of the box body 1 , and a slag outlet 33 is opened on the right side of the box body 1 .

[0028] A pressure plate 41 contacts the top of the mesh transmission belt 211, a rotating hole is opened on the front side of the pressure plate 41, a fixed column 4 is rotatably connected to the inner wall of the rotating hole, a connecting block 432 is fixedly connected to the top of the pressure plate 41, a spring 431 is fixedly connected to the top of the connecting block 432, a telescopic barrel 43 is fixedly connected to the top of the spring 431, and a fixed rod 42 is fixedly connected to the top of the telescopic barrel 43. The utility model sets a pressure plate 41, specifically, the sediment falls on the mesh transmission belt 211, and the sediment is started by the motor 2 to pass through the pressure plate 41. Due to the action of the spring 431, the pressure plate 41 can squeeze the trace water contained in the sediment to flow down from the mesh transmission belt 211, and the excess impurities will be discharged through the slag outlet 33, so as to effectively circulate and filter the leachate raw water, thereby improving the working efficiency of the equipment.

[0031] A specific application of this embodiment is as follows: leachate raw water enters the interior of the funnel 1 32 through the water inlet pipe 31, and a coagulant is put into the interior of the funnel 1 32 through the feed port 3 to allow the leachate to precipitate. The rotating column 1 21 is rotated by starting the motor 2, and the rotation of the rotating column 1 21 will simultaneously drive the rotating column 2 35 to move synchronously through the mesh transmission belt 211. The rotation speed of the rotating column 1 21 determines the rotation speed of the material transfer column 34. The rotation of the rotating column 2 35 drives the material transfer column 34 fixed on the transmission block 2 231 to rotate through the belt 23. Since the material transfer column 34 is three-quarters of a cylinder and is compatible with the bottom of the funnel 1 32, when the material transfer column 34 rotates to the notch, the impurities precipitated in the leachate will be taken down together, and the flocculated supernatant will be extracted from the funnel 1 32 by starting the water pump 121 to enter the next stage. The leachate impurities fall onto the mesh transmission belt 211. Since the surface of the mesh transmission belt 211 is meshed, a small amount of water contained in the leachate impurities can be filtered out. The movement of the mesh transmission belt 211 drives the leachate impurities on its surface to pass through the bottom of the pressure plate 41. Due to the setting of the telescopic barrel 43 and the spring 431, the pressure plate 41 is pressed downward, and a small amount of water contained in the leachate impurities is squeezed out and flows to the funnel 2 36 into the leachate raw water, and then circulated and filtered. The flocculated supernatant enters the filter box 5 through the water pipe 122, and is micro-filtered by the MBR membrane 51, so that the flocculated supernatant enters the subsequent two-stage membrane system for treatment to obtain qualified water production. The device uses the MBR membrane 51 as a microfiltration treatment unit to effectively intercept colloids and remove hydrogen sulfide, and can solve the problem of two-stage membrane colloid contamination of membrane components and even blockage of flow channels and sulfur pollution.
