Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, and more specifically, to an integrated rural sewage treatment device. Background Art

[0002] Villages lack drainage channels and sewage treatment systems, leading to the direct discharge of large quantities of untreated sewage, which significantly pollutes the receiving bodies and soil, and poses a serious threat to groundwater safety and the health of rural residents. Compared to urban sewage, rural domestic sewage contains a large number of organic pollutants, suspended solids, nutrients such as nitrogen and phosphorus, and other pollutants. It also exhibits significant variability in water quality and quantity, and a complex mix of sewage types. Simply applying sewage treatment technologies from large cities would not only require large construction investments, require extensive land use, require a long construction cycle, and create complex operations and management, it is unsuitable for rural sewage treatment.

[0003] The integrated sewage treatment equipment is suitable for treating and reusing domestic sewage from residential areas, villages, towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, government agencies, schools, military units, hospitals, highways, railways, factories, mines, tourist attractions, and similar small- and medium-sized industrial organic wastewater from slaughtering, aquatic product processing, and food processing. The sewage treated by this equipment meets the National Wastewater Treatment Integrated Discharge Standard, Level 1B.

[0004] It integrates the primary sedimentation tank, I and II stage contact oxidation tanks, secondary sedimentation tank and sludge tank into one equipment, and performs aeration in the I and II stage contact oxidation tanks, so that the contact oxidation method and the activated sludge method are effectively combined, saving the time of hiring people to design sewage treatment processes and making basic equipment. It is small in size and easy to build.

[0005] In the current integrated sewage treatment equipment, the MABR reaction tank is generally connected to the aeration equipment and cooperates with the MABR membrane to react and filter pollutants such as organic pollutants, suspended solids, nitrogen, phosphorus and other nutrients in the sewage, so as to precipitate them and achieve water purification. However, the general MABR membrane structure is generally cylindrical, and its contact area with the sewage is limited. When the aeration structure injects gas into the water, the gas is relatively dispersed, making it difficult to concentrate on the contact surface between the MABR membrane and the sewage for efficient catalysis. It is also easy to cause the sediment around the MABR membrane to move slowly, reducing the treatment efficiency. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0023] See also Figures 1 to 4In the present invention, a rural sewage integrated treatment equipment includes an integrated shell 1, three partitions 2 are fixedly connected to the interior of the integrated shell 1, and the three partitions 2 divide the interior of the integrated shell 1 from left to right into a regulating tank 3, an anoxic tank 4, an aerobic tank 5 and a membrane biological reactor 6. A regulating mechanism 7 for connecting the regulating tank 3 and the anoxic tank 4 is fixedly installed on the top of the integrated shell 1. An air supply mechanism 8 connected to the membrane biological reactor 6 is installed on the top of the integrated shell 1. The membrane biological reactor 6 is equipped with a MABR component. 9. The top outlet end of the MABR component 9 is fixedly connected to a vacuum pump 10 through a pipe, and the output end of the vacuum pump 10 is fixedly connected to a drainage pipe 11. The bottom end of the MABR component 9 is fixedly connected to a vertical conduit 12 that is connected to the air supply mechanism 8. The bottom end of the vertical conduit 12 is rotatably connected to a flow-equalizing air guide 13. A sewage pump 14 is fixedly installed on the right side of the integrated shell 1. The input end of the sewage pump 14 is connected and fixed to the bottom of the inner side of the membrane biological reactor 6 through a pipe, and the output end of the sewage pump 14 is connected to the external mud discharge area through a pipe.

[0024] In the present invention, after the solid impurities are roughly filtered out, the sewage is introduced into the interior of the integrated shell 1 and first enters the regulating tank 3, then the regulating mechanism 7 is started to set the introduction rate to guide the inside of the anoxic tank 4, and then enters the inside of the aerobic tank 5 through the through hole 15 to react in sequence to decompose the organic matter, and then enters the membrane biological reactor 6 for aeration reaction, and at the same time the air supply mechanism 8 is started to supply air and oxygen to the inside of the membrane biological reactor 6, cooperate with the MABR component 9 to react, and start the vacuum pump 10 to pump negative pressure to the MABR component 9 so that the sewage enters the filtration and then the purified clean water is pumped out and discharged, and the sludge produced by the reaction is settled to the bottom of the membrane biological reactor 6, and then the sewage pump 14 is started to discharge the sludge, and While the air supply mechanism 8 supplies air, the pressurized air flow drives the flow-equalizing air guide 13 to rotate. The flow-equalizing air guide 13 guides the sewage below it upward and mixes the air supplied, and the air rises along the surrounding surface of the MABR component 9 to improve the reaction filtration efficiency, thereby achieving the advantage that the gas supply of the device is more concentrated around the MABR membrane, improving the contact efficiency between air, water and biofilm and increasing the reaction rate. This solves the problem that the general MABR membrane structure in the prior art is generally cylindrical, and its contact area with sewage is limited. When the aeration structure injects air into the water, the gas is relatively dispersed, and it is difficult to concentrate on the contact surface between the MABR membrane and sewage for efficient catalysis, and it is easy to cause the sediment around the MABR membrane to move slowly, thereby reducing the treatment efficiency.
