Description

Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment, in particular to a domestic sewage full anaerobic digestion treatment device. Background Art

[0002] The anaerobic digestion treatment unit for domestic sewage is an efficient and environmentally friendly sewage treatment system. The unit usually consists of a primary anaerobic chamber, a secondary anaerobic chamber, and a clarification chamber. After anaerobic treatment, the sewage enters the clarification chamber where impurities are further removed by adsorbents. The purified water finally meets the discharge standards and can be directly discharged or used for farmland irrigation.

[0003] While the organic matter in the sewage in the anaerobic chamber is being decomposed by anaerobic microorganisms, domestic sewage will continue to be injected into the anaerobic chamber. However, the water quality of the sewage in the anaerobic chamber is different from that of the sewage that is not injected. When the water quality difference between the influent is large, it may affect the activity of the anaerobic microorganisms, thereby affecting the treatment effect.

[0004] In order to solve the above problems, this application proposes a domestic sewage anaerobic digestion treatment device. Utility Model Content

The anaerobic tank 201 and the pretreatment tank 204 are at the same horizontal plane. The domestic sewage is conditioned in advance through the pretreatment tank 204 and then injected into the anaerobic tank 201, effectively avoiding affecting the anaerobic microbial activity of the sewage in the anaerobic tank 201.

[0031] A support block 202 is installed on the top wall of the carrier 1, and a first transfer pump 203 is installed on the top wall of the support block 202. The suction end of the first transfer pump 203 is connected to a transfer pipe 205.

The water outlet end of the first transfer pump 203 is connected to the inner wall of the anaerobic tank 201. The support block 202 is located at the center between the anaerobic tank 201 and the pretreatment tank 204. When the first transfer pump 203 is started, the suction end of the first transfer pump 203 absorbs the sewage inside the pretreatment tank 204 through the transfer pipe 205, and then discharges it into the anaerobic tank 201 through the water outlet end of the first transfer pump 203.

[0032] Reference Figure 1-3 A pretreatment structure 3 is provided on the carrier 1, and the pretreatment structure 3 includes a water tank 301 installed on the top wall of the carrier 1. A second transfer pump 302 is installed on the top wall of the water tank 301. The outer wall of the water tank 301 is close to the outer wall of the pretreatment tank 204. The suction end of the second transfer pump 302 is connected to the inner wall of the water tank 301, and the water outlet end of the second transfer pump 302 is connected to a water pipe 303. The end of the water pipe 303 away from the second transfer pump 302 is connected to an annular pipe 304. After the pH adjuster is injected into the water tank 301, the second transfer pump 302 is started to inject the pH adjuster into the annular pipe 304 through the water pipe 303.

[0033] The inner wall of the annular tube 304 away from the water pipe 303 is connected to a connecting tube 305, and the outer wall of the connecting tube 305 is fixedly connected to the inner wall of the pretreatment tank 204. There are ten connecting tubes 305, which are evenly distributed around the circumference of the pretreatment tank 204. One end of the connecting tube 305 away from the annular tube 304 is connected to a nozzle 306, which is located inside the pretreatment tank 204, and each connecting tube 305 is equipped with a nozzle 306. In addition, the end of the connecting tube 305 away from the annular tube 304 has a certain slope, which effectively improves the spraying effect of the pH adjuster.

[0034] A limit plate 307 is installed on the inner wall of the pretreatment tank 204. The inner wall of the limit plate 307 is fixedly connected to the outer wall of the connecting pipe 305. The limit plate 307 can effectively prevent excessive domestic sewage from being injected into the pretreatment tank 204, thereby affecting the operation of the pretreatment tank 204 and the internal structure of the pretreatment tank 204.

[0035] Reference Figure 2 and Figure 4 An auxiliary structure 4 is provided on the transmission structure 2. The auxiliary structure 4 includes a motor 401 installed on the top wall of the pretreatment tank 204. A rotating rod 402 is installed at the output end of the motor 401. When the motor 401 is started, the rotating rod 402 is driven to rotate. A connecting rod 403 is installed on the bottom wall of the rotating rod 402. A fixed block 404 is installed on the outer wall of the connecting rod 403. There are multiple fixed blocks 404 distributed at equal intervals around the circumference of the connecting rod 403. The materials of the connecting rod 403 and the fixed block 404 have a certain conductive effect, and a heating wire is provided inside the connecting rod 403. When the heating wire is started, the heating of the connecting rod 403 is transferred and the sewage is heated to a certain extent.

[0036] A balancing plate 405 is installed on the side of the fixed block 404 away from the connecting rod 403, and a scraper 406 is installed on the side of the balancing plate 405 away from the fixed block 404. The outer wall of the scraper 406 contacts the inner wall of the pretreatment tank 204. Two balancing plates 405 are symmetrically distributed on each fixed block 404, and a scraper 406 is distributed on each balancing plate 405.

[0037] Working principle:

[0038] The domestic sewage anaerobic digestion treatment device injects a pH regulator into the water tank 301, then starts the second transmission pump 302 to draw the pH regulator into the water pipe 303, the annular pipe 304, and the connecting pipe 305, and then sprays it out from the nozzle 306 to adjust the domestic sewage with the pH regulator. Then, the first transmission pump 203 is started to transmit the adjusted domestic sewage to the anaerobic tank 201 through the transmission pipe 205. By adjusting the anaerobic microorganisms to a suitable range before discharging them into the anaerobic tank 201, the problem of large differences in water quality of the influent affecting the activity of the anaerobic microorganisms is effectively avoided, thereby effectively improving the effect of sewage treatment.

[0039] In the domestic sewage anaerobic digestion treatment device, the motor 401 is started to drive the rotating rod 402 to rotate. The rotating rod 402 drives the connecting rod 403 to rotate and starts the heating wire on the inner wall of the connecting rod 403. The connecting rod 403 drives the fixed block 404, the balance plate 405, and the scraper 406 to rotate, further balancing the pH regulator and the sewage.
