Description

Technical Field

[0002] Biochemical treatment is an important treatment unit in the process of industrial wastewater treatment. Conventional industrial wastewater biochemical systems mostly adopt a biochemical treatment process that combines anaerobic + anoxic + aerobic treatment, which can achieve the effect of nitrogen and phosphorus removal while reducing COD.

[0003] The land occupation of the wastewater station is a factor in evaluating the construction cost of the wastewater station. Therefore, under the premise of ensuring the treatment effect and convenient operation, minimizing the land occupation can effectively reduce the construction cost. The traditional biochemical pool method is to form a complete biochemical treatment system by connecting anaerobic + anoxic + aerobic in series in a front-to-back sequence. Each biochemical system has an independent pool body and is set separately. The wastewater flows from the anaerobic pool through the anoxic pool and finally to the aerobic pool. The aerobic mixed liquid is pumped into the inlet section of the anaerobic pool through the reflux pump for the nitrification liquid to reflux, so as to realize the denitrification function of the system. The independent setting of the pool body leads to a large land occupation area. The reflux of the nitrification liquid at the back end requires a special reflux pump. Especially for wastewater with a high nitrogen content, a high-power and high-flow reflux pump is required, which leads to high operating energy consumption. In addition, there are dead corners in the biochemical pool, which is easy to accumulate mud, affecting the biochemical treatment effect. As the operation time increases, the pool body needs to be emptied regularly to clean the sludge at the bottom of the pool. Summary of the invention

[0041] Furthermore, the middle part of the Watt pole is hinged with a drive ring sleeved on the outer circumference of the hollow shaft. When the middle part of the Watt connecting rod 33 moves up and down, the hinged drive ring can drive the hollow shaft to move up and down, thereby adjusting the aeration height of the aeration assembly 2.

[0043] Based on the above embodiment, in a possible implementation, the aeration transverse pipe 22 is configured as a self-shaped hose, and a mounting channel is provided in the direction-adjusting plate 263, and the self-shaped hose is provided in the mounting channel, and then the direction of the outlet end of the aeration transverse pipe 22 can be changed by controlling the rotation of the adjustment plate, so that the direction of the airflow sprayed by the aeration transverse pipe 22 can be changed to enhance the stirring effect on the sewage, and the water vapor mixture sprayed in the aeration transverse pipe 22 can be changed to impact the sludge layer, thereby solving the technical problem of inconvenient sludge treatment in the existing sewage treatment tank. Furthermore, in order to enhance the cleaning efficiency of the sludge, a scraper plate 264 is provided on the side of the direction-adjusting plate 263 away from the air outlet of the aeration transverse pipe 22.

With this arrangement, the Watt's connecting rod 33 can drive the driving ring mentioned above to drive the first driving shaft to move up and down during the action. At the same time, a top cover is provided on the top of the reaction tank body 1, and a guide hole is opened on the top cover. The guide hole cooperates with the Watt's connecting rod 33 to guide the up and down movement of the first driving shaft.

In addition, when it is necessary to clean the sludge accumulated in the reaction tank, this embodiment can also facilitate the outflow of the sludge by moving the filter screen upward, thereby making the structural arrangement of the entire reaction tank body 1 more reasonable.

[0046] In a possible embodiment, the adjacent edges of any adjacent direction adjustment plates 263 can be sealed against each other, the inner wall of the reaction tank body 1 is provided with an annular rubber sealing ring 11, the rubber sealing ring 11 is coaxial with the reaction tank body 1, and the end of the direction adjustment plate 263 away from the first installation axis 21 can be sealed against the inner edge of the rubber sealing ring 11; by overlapping each direction adjustment plate 263 to form a relatively sealed sealing plate, the internal space of the reaction tank body 1 is separated, and the segmented boundary of the reaction space in the reaction tank body 1 is cleaner, which is conducive to solving the technical problem that the oxygen concentration distribution near the existing aeration component 2 is not easy to control; preferably, based on the above embodiment, in an embodiment, the number of rubber sealing rings 11 is multiple, and each rubber sealing ring 11 is arranged at intervals in the vertical direction.

[0047] Compared with the prior art, the beneficial effect of the integrated biochemical reaction pool provided by the present invention is that: as the first bevel gear ring 261 rotates, each adjustment plate 263 can rotate accordingly through the engagement of the second bevel gear ring 262 with the first bevel gear ring 261, and thus the aeration cross pipe 22 installed in the adjustment plate 263 can adjust its own air outlet direction.

[0048] Moreover, the gas in the present invention can be mixed with the liquid in the liquid supply pipeline 25, so that the gas can be merged with the liquid first, so that the fusion of the gas and the sewage in the reaction tank is more complete. In addition, the mixed gas is ejected through the jet port 23 of the aeration cross pipe 22. During the rotation of the adjustment plate 263 around the installation through hole, the aeration cross pipe 22 sprays the high-pressure jet flow of the mixed oil liquid toward the inner wall of the reaction tank, which can effectively clean the inner wall and bottom wall of the reaction tank; before or during cleaning, through the rotation and axial movement of the first installation shaft 21, the adjustment plate 263 in the present invention can also scrape and clean the sludge at the bottom of the reaction tank, so as to solve the technical problem of the inconvenience of cleaning the sludge at the bottom of the existing reaction tank.

When it rises to the upper side of the aeration cross pipe 22, it is the aerobic area due to the presence of aeration. The present invention can also change the length of different reaction sections in the reaction tank by axial movement of the first installation shaft 21, and then adjust the distribution ratio of the anaerobic section, aerobic section and anoxic section according to the specific situation of the sewage. At the same time, the present invention can also drive the movement of the adjustment plate 263 by the rotation and axial movement of the first installation shaft 21, stir the sewage while aerating, and improve the compatibility of gas and sewage.
