Description

Technical Field

[0002] Compared with ordinary activated sludge, aerobic granular sludge is less prone to sludge swelling, has strong impact resistance, can withstand high organic loads, and integrates microorganisms of different properties (aerobic, facultative anerobic and anaerobic microorganisms). Recent research results show that AGS can be used to treat high-concentration organic wastewater, high-salinity wastewater and many industrial wastewaters. Corresponding reaction devices are required in the cultivation process of aerobic granular sludge.

[0003] The existing water treatment reaction device for efficiently cultivating aerobic granular sludge uses a stirring shaft to stir the raw materials so that they are in uniform contact with oxygen for cultivation during use.

[0027] The present invention provides an aerobic granular sludge reaction protection stabilization tank through improvement.

At this time, most of the organic matter is degraded here to produce a large amount of gas. In order to effectively make the various raw materials in the reaction tank 1 fully contact with oxygen, a reaction acceleration generation device is set up, and the first motor 5 drives the rotating roller 6 to rotate. A plurality of acceleration rods 7 are installed on the rotating roller 6, which leads to an increase in the stirring area, so that the various raw materials are fully reacted, the cultivation effect of the reaction tank 1 is increased, and the practicality of the reaction tank 1 is improved. Under the action of gravity, the sludge particles fall to the bottom of the second reaction chamber, and the gas and liquid are transported to the spray box 3 and the purification device respectively along with the three-phase separator 9.

[0029] As a preferred embodiment, further, a drying chamber and a sludge treatment device are provided in the sludge treatment box 4, a conveyor belt 10 is installed below the sludge treatment device, a heating layer 11 is provided on the inner wall of the drying chamber, a group of symmetrically arranged guide plates 12 are provided below the drying chamber, two of the guide plates 12 are respectively fixedly connected to the inner walls of the drying chamber, a first electric push rod 13 is fixedly connected to the inner wall on the lower side of the drying chamber, and a push plate 14 is fixedly connected to the first electric push rod 13.

During the driving and lateral movement of the second electric push rod 16, the mud pressing roller 17 repeatedly crushes the sludge on the conveyor belt 10 until it is pressed into sludge sheets. When the sludge sheets are transported to the mud discharge port 32, the third electric push rod 19 drives the shovel plate 20 to scrape the sludge sheets on the conveyor belt 10 to prevent the sludge from being adhered to the conveyor belt 10 under the gravity crushing of the mud pressing roller 17 and being difficult to fall off. By setting up a sludge treatment device, the area occupied by the sludge can be further compressed, which is convenient for subsequent transportation.

[0033] As a preferred embodiment, further, a first water pump 21 is installed above the spray box 3, the water outlet end of the water pump is connected to a water pipe 22, one end of the water pipe 22 extending to the inner cavity of the spray box 3 is connected to a plurality of spray heads 23, a sewage drain outlet 24 is opened on one side of the spray box 3, and a one-way valve 25 is installed above the sewage drain outlet 24.

[0034] It should be noted that the first water pump 21 is connected to an external water source, and its spray head 23 sprays the water body below through the connected water pipe 22, thereby degrading harmful impurities in the water body and then discharging them, effectively improving the sewage discharge standard.

[0035] As a preferred embodiment, further, the purification device includes a bracket 26, an air suction pump 27, a purification box 28, and a honeycomb activated adsorption carbon layer 29. The bracket 26 is fixedly mounted on an outer wall of one side of the reaction tank 1, a purification box 28 is mounted on the bracket 26, a honeycomb activated carbon layer 29 is mounted on the inner wall of the purification box 28, an exhaust port is opened on one side of the purification box 28, a mounting cover is installed on the exhaust port, the suction end of the air suction pump 27 is connected to the outlet of the three-phase separator 9, and the outlet end of the air suction pump 27 is connected to the purification box 28.

[0036] It should be noted that by setting up a purification device, the suction pump 27 sucks the gas generated by the reaction in the reaction tank 1 into the purification box 28. Under the adsorption action of the honeycomb activated adsorption carbon layer 29, the gas can further adsorb harmful gases and irritating odors in the gas, avoiding direct discharge to the outside and polluting the working environment.

[0038] It should be noted that by setting up the sedimentation box 2, after the organic wastewater is introduced into the sedimentation box 2 from the feed port 30, the impurities in the organic wastewater can be precipitated at the bottom of the box through preliminary static sedimentation, which is beneficial to the subsequent reaction generation, and the impurities precipitated at the bottom of the box can be discharged through the mud discharge port 32 for further treatment.

[0039] As a preferred solution, further, a connecting groove 34 is opened between the reaction tank 1 and the sludge treatment box 4, a sealing plate 35 is slidably connected above the connecting groove 34, and a pull rod 36 is fixedly connected to one end of the sealing plate 35 away from the reaction tank 1.

[0040] It should be noted that, by providing a sliding-fitting sealing plate 35, when the water and gas in the reaction tank 1 are transported to other devices along with the three-phase separator 9, the sludge at the bottom of the reaction tank 1 needs to be processed. By pulling the pull rod 36 from the outside, the connecting groove 34 is opened, and the sludge falls into the sludge treatment box 4 below through the connecting groove 34. By providing the sealing plate 35, the independent sealing of the reaction tank 1 and the sludge treatment box 4 is ensured.

[0041] Working principle: When the device is used, first, the organic wastewater enters the sedimentation tank 2. After the organic wastewater is introduced into the sedimentation tank 2 from the feed port 30, the impurities in the organic wastewater can be precipitated at the bottom of the tank through preliminary static sedimentation, which is beneficial to the subsequent reaction generation, and the impurities precipitated at the bottom of the tank can be discharged through the mud discharge port 32 for further treatment. The organic wastewater after static sedimentation is pumped into the reaction tank 1 and mixed with the aerobic granular biological sludge in the second reaction chamber. At this time, most of the organic matter is degraded here and a large amount of gas is generated. In order to effectively make the various raw materials in the reaction tank 1 fully contact with oxygen, a reaction acceleration generation device is set up, and the first motor 5 drives the rotating roller 6 to rotate. A plurality of acceleration rods 7 are installed on the rotating roller 6, which leads to an increase in the stirring area, so that the various raw materials are fully reacted, the culture effect of the reaction tank 1 is increased, and the practicality of the reaction tank 1 is improved. Under the action of gravity, the sludge particles fall to the bottom of the second reaction chamber, and the gas and liquid are transported to the spray box 3 and the purification device respectively with the three-phase separator 9;

[0042] Secondly, the first water pump 21 above the spray box 3 is connected to an external water source, and its spray head 23 sprays the water below through the connected water pipe 22, thereby degrading harmful impurities in the water and then discharging them, effectively improving the sewage drainage standard;

[0043] Then, by setting up a purification device, the suction pump 27 sucks the gas generated by the reaction in the reaction tank 1 into the purification box 28. Under the adsorption action of the honeycomb activated adsorption carbon layer 29, the gas can further adsorb harmful gases and irritating odors in the gas, avoiding direct discharge to the outdoors and causing pollution to the working environment;

[0044] Finally, the sludge falls into the drying chamber below through the connecting groove 34. The heating layer 11 can reduce part of the moisture in the sludge. The sludge falls to the bottom of the drying chamber through the guide plate 12. Driven by the first electric push rod 13, the push plate 14 pushes the sludge onto the conveyor belt 10. Under the action of the heating layer 11, the sludge can effectively reduce part of the moisture in the sludge. Subsequently, under the push of the push plate 14, part of the sludge is pushed onto the conveyor belt 10. The motor of the screw slide 15 above the conveyor belt 10 drives its moving end to drive the pressure The mud roller 17 moves, and during the driving and lateral movement of the second electric push rod 16, the mud pressing roller 17 repeatedly crushes the sludge on the conveyor belt 10 until it is pressed into sludge sheets. When the sludge sheets are transported to the mud discharge port 32, the third electric push rod 19 drives the mud shovel plate 20 to scrape the sludge sheets on the conveyor belt 10 to prevent the sludge from being adhered to the conveyor belt 10 and difficult to fall off under the gravity crushing of the mud pressing roller 17. By setting up a sludge processing device, the area occupied by the sludge can be further compressed, which is convenient for subsequent transportation.
