Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a high-efficiency sewage treatment device in a confined space. Background Art

[0002] For closed living environments, there are currently two types of sewage treatment methods. One is traditional buried sewage treatment, which requires the joint operation of several underground pools. Not only is the space large, but the treatment time is also relatively long. The most important thing is that it requires artificial cultivation of bacteria to maintain the activity of the bacteria, thereby increasing the workload of personnel; the other is sewage treatment equipment, which has a small sewage treatment volume, a strong odor in the sewage treatment room, a waste of domestic water (the disinfection device in the equipment requires a large amount of cooling water), and a rich content of organic matter produced in the biochemical process.

[0003] During the use of existing sewage treatment equipment, the generated activated sludge is directly pumped to the screw stacking machine through a sewage pump, and the flocculant in the dosing barrel is pumped into the screw stacking machine through a drug pump to flocculate the solids in the activated sludge, achieve mud and water separation, and finally transport the mud cake out. However, the treated activated sludge is difficult to fully mix with flocculants and other drugs. The two are mixed unevenly, resulting in insufficient reaction and a large sludge settling ratio, which leads to poor sludge dehydration effect. The discharged mud cake is mixed with a large amount of water. The sludge mixed with water adheres to the sewage outlet of the screw stacking machine, affecting the transportation of the mud cake. Summary of the invention

[0035] Specifically, during the reaction process, air is blown in by the aeration blower 17, transported through the air pipe 18 and discharged evenly through the aeration plate 19, the sewage is stirred and reacted, and the supernatant after precipitation is pumped out by the water pump 21 in the middle of the reaction tank 1, transported to the ultraviolet disinfector 23 through the water pipe 22, and directly discharged through the drain pipe 24 after disinfection by the ultraviolet disinfector 23; the odor in the reaction tank 1 is treated by the activated carbon adsorption device 25, the exhaust gas exhaust fan 29 is started, and the odor in the reaction tank 1 is transported to the activated carbon adsorption device 25 through the exhaust pipe 27 for filtration and deodorization treatment, and the treated odor is discharged to the exhaust pipe to avoid pollution to the environment.

[0036] The deodorization and disinfection device is mainly based on the problem of odor in the sewage treatment area of ​​the confined space and waste of domestic water. The use of an ozone generator will cause residual ozone to bring odor to the treatment area environment, and the cooling water cooling will cause waste of domestic water, and the discharge of cooling water into the sewage pool will increase the amount of sewage. The deodorization device is designed as an activated carbon air purification device. The designed activated carbon adsorption device only operates in the aeration stage. Only this stage will produce odor. This design is more energy-efficient. A one-way valve is set on the pipeline entering the activated carbon device to isolate the water vapor in the reaction pool from entering the activated carbon, thereby extending the service life and adsorption effect of the activated carbon. The air treated with activated carbon enters the exhaust duct and is discharged from the confined space by the exhaust duct, avoiding the generation of odor in the confined space and ensuring the air quality in the confined space.

[0037] The outer wall of the reaction tank 1 is fixedly installed with a pre-dosing box 26, and the pre-dosing box 26 is built with a flocculant. The pre-dosing box 26 is installed with a dosing pump, and the dosing pump adds the flocculant built in the dosing box to the reaction tank. After the activated sludge is aerated in the reaction tank, a high-efficiency nano-flocculant is pre-added through the pre-dosing box to make the reaction sufficient, convert the biodegradable organic matter in the sewage into a carbon source, and achieve sedimentation, break the wall and digest the excess residual sludge, and achieve sludge reduction. The dosing pump and the flocculant in the pre-dosing box are not shown in the accompanying drawings. The flocculant is a high-efficiency nano-composite flocculant, which is a high-efficiency nano-composite flocculant based on inorganic nano-iron formed by combining metal oxide nanoparticles with special charge organic carriers. The nano-flocculant does not contain artificially synthesized nano-materials and will not affect the environment. The flocculation and sedimentation mechanism of nano-flocculants is mainly adsorption and charge neutralization. Negatively charged sludge and positively charged nano-particles are charged neutralized, and the g potential is reduced, and the electrostatic repulsion is reduced. In addition, it is supplemented by adsorption bridging. The chain molecules of the polymer in the flocculant act as bridges and ties, so that the suspended matter is bridged and connected into floccules. Therefore, nano-flocculants can make sludge quickly form floccules and achieve rapid sedimentation, thereby achieving rapid mud-water separation.

[0038] Working principle: A self-locking universal wheel 9 is installed at the bottom of the mounting seat 8, which can be fixed anywhere or moved, which saves space and reflects the beauty of the equipment. When in use, a double-sided spiral reamer is set at the suction port of the reamer sludge pump, and fine granular protrusions are set on the contact surface of the blade and the blade to increase the roughness of the contact surface, which plays a grinding role, and grinds the long fibers, plastic bags and other materials in the septic tank into debris, and mixes with sewage and evenly enters the bottom of the reaction tank through the sewage delivery pipe 3. During the reaction, air is blown in by the aeration blower 17 and transported through the air delivery pipe 18 The wastewater is uniformly discharged through the aeration plate 19, the wastewater is stirred and reacted, and the supernatant after precipitation is pumped out by the water pump 21 in the middle of the reaction tank 1, and transported to the ultraviolet disinfector 23 through the water pipe 22. After disinfection by the ultraviolet disinfector 23, it is directly discharged through the drain pipe 24; the odor in the reaction tank 1 is treated by the activated carbon adsorption device 25, the exhaust gas exhauster 29 is started, and the odor in the reaction tank 1 is transported to the activated carbon adsorption device 25 through the exhaust pipe 27 for filtering and deodorization. The treated odor is discharged to the exhaust pipe to avoid pollution to the environment;The activated sludge at the bottom of the pool is pumped out by the sewage pump 6, and then transported to the dosing barrel 10 through the sewage delivery pipe 7 and the sewage inlet 12, and flocculant is added to the dosing barrel 10 through the dosing hopper 14, and water is added to the dosing barrel 10 through the water inlet 13. The driving motor 1502 is started to rotate the rotating plate 1503, and the rotating plate 1503 slides back and forth along the inside of the movable groove 1507, so that the rotating frame 1506 drives the arc rack 1508 to reciprocate, and the arc rack 1508 is meshed with the gear 1509. The stirring rod 1510 drives the stirring blade 1511 to rotate inside the dosing barrel 10 to achieve the ratio of flocculant and water. After the activated sludge enters the dosing barrel 10, the proportioned flocculant is added to the bottom of the separation plate 1512 through the discharge pipe 1513. The stirring rod 1510 drives the triangular plate 1514 to rotate, and the multiple gears 1515 are all meshed with the gear 3 1517, so that the multiple gears 1515 change their positions and rotate accordingly. At the same time, the rotating plate 1519 rotates around the positioning rod 1518. The gear 4 1520 is meshed with the annular rack 1521, so that the stirring rod 2 1522 drives the stirring blade 2 1523 to rotate. The stirring blade 2 1523 changes position inside the dosing barrel 10 and rotates back and forth continuously, so as to achieve full mixing of the flocculant and the activated sludge. The flocculant and the activated sludge are then transported to the screw stacking machine 11, where they are squeezed and dehydrated to form a mud cake with very low water content, which is convenient for transportation. The mud cake squeezed and dehydrated by the screw stacking machine 11 is discharged through the sewage outlet, and the driving motor 2 1602 is started to make the rotating plate 3 16 03 rotates, driving the eccentric block 1604 to slide back and forth along the inside of the movable groove 1606, so that the movable frame 1605 drives the mounting plate 1607 to move back and forth along the outer wall of the sewage outlet, and the guide block 1608 slides back and forth along the inside of the guide groove 1609, driving the combing scraper 1611 to slide along the inner wall of the sewage outlet to prevent the mud cake from adhering to the inner wall of the sewage outlet. The discharged mud cake is combed through the connecting rod 1610 to prevent the mud cake from clogging in the sewage outlet, thereby ensuring the discharge efficiency of the mud cake and improving the efficiency of sludge treatment. ;

The water inlet method is bottom water inlet, and the water is discharged by top-out type. The mass concentration of DO in the aerobic stage is controlled at 1.5-4.5 mg / L, the temperature is room temperature (20-29 ℃), and the dosage of nano-flocculant is 20μL / L. In comparison, the traditional underground treatment cycle is 9-15 hours, and the present equipment is more efficient.

[0040] The equipment of the present invention also realizes the "zero" emission technology, adopts microbial purification means, aerates the reaction tank, and has a long aeration time.
