Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection wastewater treatment, in particular to a sewage deep carbon removal reactor. Background Art

[0002] Sewage usually refers to water discharged from life and production that is polluted to a certain extent, mainly including domestic sewage, industrial sewage and agricultural sewage. Domestic sewage comes from the daily lives of residents, such as washing, flushing toilets, kitchen drainage, etc. Its composition is relatively complex, but the concentration of harmful substances is generally low. Industrial sewage is wastewater generated by various industrial production processes. Depending on the type of industry, the pollutants contained vary greatly, and may include heavy metals, organic matter, acidic and alkaline substances, etc. For example, wastewater from the chemical industry may contain a large amount of toxic chemicals, while wastewater from paper mills may be rich in fiber and chemical additives. Agricultural sewage mainly comes from farmland irrigation drainage, the use of pesticides and fertilizers, etc., and often contains pesticide residues, nutrients such as nitrogen and phosphorus. In order to meet higher emission standards and reduce pollution to the environment, sewage is usually subjected to deep removal of organic matter.

[0003] Existing advanced wastewater treatment typically utilizes ozone oxidation combined with a biological aeration filter as a tertiary treatment process to achieve deep removal of organic matter from wastewater. This process combines the strong oxidizing properties of ozone oxidation with the biodegradation of the biological aeration filter to efficiently remove organic matter from wastewater. Ozone oxidation breaks down large organic molecules into small molecules, improving the biodegradability of wastewater, while the biological aeration filter further removes organic matter through microbial metabolism. This combined process offers advantages such as high treatment effectiveness, stable operation, and a small footprint.

[0004] However, for existing advanced wastewater treatment, traditional aerated biological filters (BAFs) often use ceramsite, volcanic rock, or quartz sand as biofilter media, and are mostly upflow filters. Aerated BAFs inject aeration air to provide oxygen to the microorganisms, and typically employ single-pore membrane aerators placed within the filter media layer. Maintenance of the aerators requires emptying the filter media, a significant workload. Based on engineering operation experience, the dissolved oxygen content in the effluent from ozone oxidation is usually higher than 10 mg / L, which is sufficient to meet the needs of subsequent degradation of trace organic matter in the influent of the aerated biological filter. Moreover, after a period of operation, the suspended solids in the influent of the aerated biological filter and the residual sludge produced by the proliferation of microorganisms will clog the filter media. In the air-water backwash mode, the influent, backwash water, and backwash gas are evenly distributed through the long-handled filter head. Once the filter head is clogged, maintenance and cleaning are very difficult. At the same time, because the backwash water volume is greater than the influent water volume, the number and arrangement of the long-handled filter heads are selected according to the backwash water volume, and the distribution of the influent is difficult to achieve uniformity. It is necessary to use pipe water distribution under the filter plate. Therefore, a sewage deep decarbonization reactor is proposed to solve the above problems. Utility Model Content

A flushing air port 24 is provided on the top of the lower area, which is connected to the flushing air pipe 26. A water outlet connecting port 25 is provided at the bottom of the lower area, which is connected to the flushing air pipe 26 respectively. The washing water pipe 27 and the outlet connecting pipe 31 are connected, the drainage trough 16 is located below the water inlet channel 1, the water distribution channel 2, and the connecting channel 3, the outlet connecting pipe 31 is also connected to the balancing water trough 9, and the balancing water trough 9 is connected to the outlet trough 10 through the outlet overflow weir 11 on the upper part of the partition wall. The outlet trough 10 is provided with an outlet pipe 32, the balancing water trough 9 and the outlet trough 10 are located on the outlet side of the reaction tank and are arranged sideways. The top of the washing water trough 8 is at the same height as the bottom of the water distribution trough 7. In particular, the washing water trough 8 is provided with a screen 38 for intercepting filter materials. There are two screens 38, which are arranged symmetrically. One end of the screen 38 is provided with a central axis 40 fixed to the top of the washing water trough 8, and the other end is provided with a hanging ear 39. The wire rope 19 is tied to the hanging ear 39, and the winch unit 20 pulls the wire rope 19 to drive The end of the screen 38 ear 39 is open and rotates around the central axis 40. The winch unit 20 is installed on the winch bracket 21 on the top of the reaction tank. A cleaning nozzle 22 is provided between the two screens 38. The cleaning nozzle 22 is connected to the screen cleaning water pipe 29. The flushing tank 8 divides the reaction tank into two symmetrical grids, each grid is filled with biological filter material 18, and the biological filter material 18 is supported by the filter material bracket 13 located below the reaction tank. A feeding column 15 is also provided under the filter material bracket 13. The filter material bracket 13 is at the same height as the diaphragm 42 in the flushing tank 8. The space below the filter material bracket 13 and the space below the diaphragm 42 in the flushing tank 8 are connected through a row of air vents 43 at the top and a row of water holes 44 at the bottom. A self-flushing filter head 14 is installed on the filter material bracket 13, and then from the bottom A filter material cushion layer 17 and biological filter material 18 are laid on it, and a self-flushing filter head is provided, which consists of a filter cap 33, a mounting base 34, a filter rod 35, an air hole 36 and a self-flushing air hole 37. Different from the traditional filter head, the filter head is provided with a self-flushing air hole 37 on the connecting pipe below the filter cap 33 and above the mounting base 34. The self-flushing air hole 37 is connected to the filter head flushing air pipe 28. The sludge on the filter cap 33 is flushed and removed by the instantaneous injection of blast air. The improvement of its water distribution effect is a highlight. It is no longer limited to the long-handled filter head, and the water inlet is evenly distributed. This feature greatly improves the mass transfer efficiency. The uniform water inlet distribution ensures that the sewage can more fully contact the filter material, making the treatment process more efficient and stable. For example, when treating high-concentration organic wastewater,Uniform water inlet distribution can make organic matter more evenly decomposed by microorganisms, thereby improving the treatment effect. Secondly, the dissolved oxygen in the ozone effluent is used to provide oxygen for microorganisms, without the need to add additional blower air for aeration. This design not only saves operating costs, but also simplifies the process flow, thereby reducing the investment and maintenance costs of aeration equipment during operation. At the same time, the self-flushing filter head 14 is provided with an air flushing structure, which effectively avoids the filter head clogging phenomenon, eliminates the filter head inspection and maintenance work, greatly reduces the workload and cost of equipment maintenance, and improves the reliability and stability of the system. In long-term operation, it reduces the decline in treatment efficiency and shutdown maintenance caused by filter head clogging. At the same time, by flushing the filter material retention screen of the water tank 8, the filter material loss caused by backwashing is effectively avoided, which is crucial to maintaining the treatment capacity and long-term stable operation of the filter tank. For example, in some working conditions where backwashing is frequently performed, the interception screen can keep the filter media in the filter tank at all times, ensuring that the treatment effect is not affected. Finally, the electrically open and close screen also reduces the workload. The screen opens when flushing and closes when in use, achieving excellent cleaning effect. This intelligent control method not only improves work efficiency, but also enables more precise control of the flushing process, ensuring the smooth operation of the filter tank.

[0033] Working principle: Sewage enters the inlet channel 1 from the inlet pipe 41 of the sewage deep carbon removal reactor, passes through the flow hole 4 to the distribution channel 2, enters the connecting channel 3 after the flow is distributed by the inlet overflow weir 5, and then enters the water distribution trough 7 in the reaction tank through the connecting flow hole 6, enters the reaction tank through a row of water distribution holes 12 at the bottom of the water distribution trough 7, passes through the biological filter material 18, the filter material cushion layer 17, and the self-flushing filter head 14 from top to bottom, and reaches the lower area of the filter material bracket 13. At this time, the sewage enters the area below the cross plate 42 of the flushing trough 8 through a row of water holes 44 at the bottom of the partition wall of the flushing trough 8, enters the balancing trough 9 through the outlet connecting port 25 and the outlet connecting pipe 31, and enters the outlet trough 10 after adjusting the outlet liquid level through the outlet overflow weir 11, and is discharged through the outlet pipe 32. The sewage passes through the biological filter material 18 from top to bottom in the reaction tank, and the water distribution is no longer affected by the filter head. The inlet distribution is even and the mass transfer efficiency is high.At the same time, the remaining dissolved oxygen in the effluent from ozone oxidation is usually above 10 mg / L. The reaction tank no longer uses additional blast air to oxygenate the microorganisms, saving operating costs. The flushing water tank 8 in the reaction tank is divided into two upper and lower areas by the transverse partition 42. The upper area realizes the flushing and drainage function, and the lower area realizes the effluent collection, flushing and air distribution function. After running for a period of time, the filter material will be blocked due to the increase of suspended matter in the influent and the residual sludge produced by the proliferation of microorganisms. At this time, the air-water combined flushing is used to flush the biological filter material 18. When flushing, first open the valve on the drain pipe 30, and the sewage above the biological filter material 18 is flushed out through the flushing pipe. The area above the transverse partition 42 of the washing tank 8 is discharged into the drainage tank 16 through the drain pipe 30. When the liquid level drops to the top of the partition wall of the washing tank 8, the valve on the flushing air pipe 26 is opened at this time, and the blast air enters the area below the transverse partition 42 of the washing tank 8 through the flushing air port 25, and then enters the area below the filter material bracket 13 through the vent 43 to form an air cushion layer. When the air cushion layer gradually thickens to the position of the air hole 36 on the self-flushing filter head 14, the flushing gas enters the filter material layer through the self-flushing filter head 14, disturbing the biological filter material 18 to achieve air flushing. After a period of air flushing, the valve on the flushing water pipe 27 is opened, and the flushing water passes through the water outlet connection port 25 enters the area below the transverse partition 42 of the flushing tank 8, and then enters the area below the filter bracket 13 through the water hole 44. After being evenly distributed by the self-flushing filter head 14, it passes through the biological filter material 18 from bottom to top. At this time, it is a combined air and water flushing. After the air flushing is completed, the valve on the air washing pipe 26 is closed and a single water flushing is performed. After a period of single water flushing, the valve on the flushing water pipe 27 and the valve on the drain pipe 30 are closed. The flushing is completed and normal operation is restored. During the entire flushing process, the valve on the water inlet pipe 41 is always open, and the incoming water is used to sweep the surface, pushing the foam and mud floating on the biological filter material 18 during the flushing process into the flushing tank 8. The area above the diaphragm 42 and the connecting pipe below the filter cap 33 and above the mounting base 34 of the filter head are equipped with self-flushing air holes 37. These self-flushing air holes 37 are connected to the filter head flushing air pipe 28. When the self-flushing filter head 14 becomes clogged and affects the water flow rate, the valve on the filter head flushing air pipe is opened, and the sludge on the filter cap is flushed away by the instantaneous injection of blast air. When the screen 38 becomes clogged and affects the flushing and drainage flow rate, the hoisting unit 20 is activated to adjust the screen 38 from an inclined position to a vertical position. Then, the valve on the screen cleaning water pipe 29 is opened, and flushing water is sprayed from the cleaning nozzle 22 to flush the screen. After flushing is complete, the hoisting unit 20 is closed, closing the screen 38 to its inclined position.

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.
