Description

Technical Field

[0001] The present invention relates to the technical field of wastewater purification, and specifically relates to an industrial wastewater purification and restoration treatment device. Background Art

[0002] The technical principle of using microorganisms to purify industrial wastewater generally refers to microorganisms such as bacteria, fungi, and algae that play a role in decomposing organic matter, removing pollutants, and improving water quality during the water treatment process. The survival and activity of these microorganisms are closely related to their environmental conditions, including water temperature, oxygen concentration, pH value, availability of nutrients, etc.

[0003] After retrieval, the existing publication number CN115991534B discloses a biological membrane multi-stage treatment device for industrial wastewater with a telescopic mechanism, including a multi-stage treatment device main body, a biological reaction tank, and an aeration rod. The bottom of the aeration rod is fixedly connected with an aeration pipe, and a gas-dispersing nozzle is fixedly connected to the outer surface wall of the aeration pipe. The treatment device further includes: a receiving block and a disc. In the present invention, by rotating the rotating handle, the first screw rod rotates, and two groups of first screw sleeves on the first screw rod move synchronously towards the center or both sides. The first connecting rod and the second connecting rod are fixedly connected to the first screw sleeve through a fixing rod, and the centers of the first connecting rod and the second connecting rod are connected through a rotating shaft, so that the first connecting rod and the second connecting rod expand or contract synchronously outwards or inwards, and the discs at their bottoms can synchronously adjust the spacing accordingly, improving the growth environment of microorganisms, enhancing the purification efficiency of microorganisms, and improving the use effect of the product.

[0004] Since the survival and activity of microorganisms are closely related to their environmental conditions, including water temperature, oxygen concentration, pH value, availability of nutrients, etc., it is necessary to monitor and manage microorganisms, including real-time detection of their growth status, metabolic activities, and pollutant removal efficiency. However, on the one hand, the above biological membrane multi-stage treatment device cannot automatically separate the microbial flora from the wastewater for monitoring, and on the other hand, it can only adjust the disc spacing singly. Due to the single movement direction or position of the disc, it is impossible to ensure the uniform contact between microorganisms and pollutants with different concentrations at different positions to the maximum extent, thus unable to complete the purification work of wastewater efficiently.

Pulleys are respectively fixedly connected to the surfaces of the upper driven rod 4 and the lower driven rod 5.

The microbial attachment zone 3 is in sliding contact with the pulleys.

[0050] Please refer to Figure 1 and Figure 7 , further, it further includes a top cover 1, a sewage inlet pipe 10, a purifying agent inlet pipe 11 and a reaction gas discharge pipe 12. The sewage inlet pipe 10, the purifying agent inlet pipe 11 and the reaction gas discharge pipe 12 are all fixedly connected to the top cover 1.

[0052] Please refer to Figure 6 and Figure 7, in an embodiment of the present invention, the housing mechanism 9 further includes a thermostatic and humidostatic box 91, a box cover 92 and a control display 96.

The first driving rod 6 and the second driving rod 7 are respectively connected inside the two thermostatic and humidostatic boxes 91.

[0053] Please refer to Figure 8 and Figure 9 , further, the housing mechanism 9 further includes a scraper 95. The surface of the microbial attachment belt 3 is in sliding contact with the scraper 95.

[0054] In an embodiment of the present invention, the thermostatic and humidostatic box 91 is used to provide ideal temperature, pH, nutrients and other growth and breeding conditions for microorganisms. When the microbial attachment belt 3 moves past the scraper 95, the scraper 95 can clean the sludge and metabolites attached to the surface of the microbial attachment belt 3. Since the microbial flora is attached inside the through holes 31, the scraper 95 will not damage the microbial flora. This can not only improve the service life of the microbial attachment belt 3, but also recycle and utilize the by-products produced by the microorganisms (such as metabolites or dead microbial flora), realizing the circular utilization of resources. For example, the dead microbial flora can be used as biological fertilizer.

[0055] Working principle: When using the microbial attachment belt 3 to purify wastewater, according to the movement rules of the microbial attachment belt 3 controlled by the first driving motor 61 and the second driving motor 71, the following two wastewater purification methods can be divided:

[0056] Method 1: Control the lower driven rod 5 to move up and down at a certain frequency. First, use the control display 96 to control the first driving motor 61 and the second driving motor 71 to start at the same time. The first driving motor 61 and the second driving motor 71 first control the first winding wheel 62 and the second winding wheel 72 to rotate counterclockwise and clockwise respectively. After a certain period of time, control the first winding wheel 62 and the second winding wheel 72 to rotate clockwise and counterclockwise respectively. Since the first winding wheel 62 and the second winding wheel 72 rotating counterclockwise and clockwise respectively can wind the microbial attachment belt 3 from both ends at the same time, the microbial attachment belt 3 wound or pulled at both ends can drive the telescopic rod 81 to slide upward along the swing disk 82. Since the first winding wheel 62 and the second winding wheel 72 rotating clockwise and counterclockwise respectively can release the microbial attachment belt 3 from both ends, the gravity of the lower driven rod 5 can drive the telescopic rod 81 to slide downward along the swing disk 82;

[0057] Method 2: The driven rod 5 reciprocates and swings according to a certain frequency control. First, control the first drive motor 61 to rotate counterclockwise, so that it can wind from one end of the microbial attachment belt 3 onto the surface of the first winding wheel 62. Driven by the frictional force or traction force between the sliding microbial attachment belt 3 and the lower driven rod 5, the swing disk 82 and the lower driven rod 5 can not only swing towards the first drive motor 61 with the rotation axis 83 as the axis. When the convex platform 84 contacts one side of the limit frame 94, the telescopic rod 81 can also slide along the swing disk 82. Then, control the second drive motor 71 to rotate counterclockwise. The swing disk 82 and the lower driven rod 5 can not only swing towards the second drive motor 71 with the rotation axis 83 as the axis. When the convex platform 84 contacts the other side of the limit frame 94, the telescopic rod 81 can also slide along the swing disk 82.

[0058] The lower driven rod 5 and the telescopic rod 81 that move up and down and reciprocate swing according to a certain frequency can, on the one hand, stir the wastewater to increase the fluidity of the wastewater, and on the other hand, can adjust the spatial position of the microbial flora on the surface of the microbial attachment belt 3 in the wastewater, so as to control the contact between the microbial flora and pollutants with different concentrations inside the wastewater, not only for improving the purification or degradation efficiency of pollutants, but also for enhancing the activity of the microbial flora.

[0059] In addition, when both ends of the microbial attachment belt 3 are wound, a part of the microbial flora on the wound surface of the microbial attachment belt 3 temporarily detaches from the wastewater and enters the constant temperature and humidity box 91. By separating the microbial flora from the wastewater, it can not only be centrally treated in a more suitable environment (the constant temperature and humidity box 91 can provide more ideal culture conditions for the microbial flora, such as temperature, pH, nutrients, etc.), so as to promote its rapid reproduction and metabolism, enhance the degradation ability of pollutants, and improve the efficiency and effect of sewage treatment, but also facilitate its monitoring and management, including the real-time detection of its growth state, metabolic activities and pollutant removal efficiency. And under specific conditions, the microorganisms detached from the wastewater can reduce the direct impact on the water body, thus reducing the risk of secondary pollution, especially when there are toxic and harmful substances in the wastewater.

[0060] When one of the microbial attachment belts 3 needs to be replaced, first open the box cover 92, then fix one end of the new microbial attachment belt 3 to one end of the old microbial attachment belt 3, and then control the first winding wheel 62 or the second winding wheel 72 (taking the first winding wheel 62 as an example) to wind the old microbial attachment belt 3 until the new microbial attachment belt 3 is wound on the surface of the first winding wheel 62 and then stop. At this time, remove the old microbial attachment belt 3, fix one end of the new microbial attachment belt 3 on the surface of the first winding wheel, continue to control the first winding wheel 62 to rotate for winding until the other end of the new microbial attachment belt 3 can be fixed on the surface of the second winding wheel 72, and then control the second winding wheel 72 to wind the new microbial attachment belt 3 in the reverse direction, which has the characteristic of being convenient for replacing the microbial attachment belt 3.

[0061] In summary, by simultaneously pulling the microbial attachment belt 3 from both ends and pulling it from one end alone, the present application can achieve the purpose of controlling the up-and-down movement and reciprocating swing of the driven rod 5 and the telescopic rod 81 at a certain frequency, which not only improves the purification or degradation efficiency of pollutants, but also improves the activity of the microbial flora.

[0062] The method of the present application for controlling the microbial flora on the surface of the microbial attachment belt 3 to temporarily separate from the wastewater and enter the constant temperature and humidity box 91 can not only be centrally treated in a more suitable environment, thereby promoting its rapid reproduction and metabolism, enhancing the degradation ability of pollutants, and improving the efficiency and effect of sewage treatment, but also be convenient for monitoring and managing its growth state, metabolic activities and pollutant removal efficiency.

[0063] The method of the present application for using the scraper 95 to clean the sludge and metabolites attached to the surface of the microbial attachment belt 3 can not only improve the service life of the microbial attachment belt 3, but also recycle and utilize the by-products produced by the microorganisms, thereby realizing the recycling of resources.
