Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a process device for improving sewage treatment capacity. Background Technique

[0002] Aeration treatment is a process in sewage treatment. By aeration, the oxygen content in the sewage is increased so that aerobic bacteria can decompose the organic pollutants in the sewage. However, the existing sewage aeration devices can only ventilate the sewage to increase the oxygen content, but cannot adjust the water temperature. The suitable temperature for aerobic bacteria in the sewage is 15-35°C. When the weather temperature is too high or too low, the temperature of the sewage is also too high or too low. Too high or too low temperature will greatly reduce the activity of the bacteria and affect the decomposition rate of the bacteria on the organic pollutants. Therefore, in view of the above situation, there is an urgent need to develop a process device for sewage aeration treatment that is convenient to adjust the temperature of the sewage according to the weather temperature, so that the bacteria can maintain high activity and improve the decomposition rate of the bacteria on the organic matter, so as to overcome the deficiencies in current practical applications and meet the current needs. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a process device for improving sewage treatment capacity, which is convenient for sewage aeration treatment and is convenient to adjust the temperature of the sewage according to the weather temperature, so that the bacteria can maintain high activity and improve the decomposition rate of the bacteria on the organic matter.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A process device for improving sewage treatment capacity, comprising a sewage aeration tank, a temperature-adjusting aeration mechanism, a dust filtration mechanism, a transverse movement mechanism and a sludge cleaning mechanism. The temperature-adjusting aeration mechanism extending into its interior is installed on one side of the sewage aeration tank. The dust filtration mechanism is connected to the temperature-adjusting aeration mechanism. The transverse movement mechanism is installed on the top of the sewage aeration tank.

The temperature-adjusting aeration mechanism includes: a high-pressure blower, a water storage tank, a shunt pipe, a conduit, air outlet holes, a heat exchange pipe, an electric heating rod, a semiconductor refrigeration sheet and a one-way valve. The heat exchange pipe is installed in the water storage tank. The high-pressure blower is connected to the heat exchange pipe. The heat exchange pipe is connected to the shunt pipe. The one-way valve is installed on the shunt pipe. A plurality of conduits inserted into the bottom end inside the sewage aeration tank are installed on the shunt pipe. A plurality of air outlet holes are arranged at the bottom of each conduit. The electric heating rod is installed in the water storage tank. A plurality of semiconductor refrigeration sheets are installed on the outer side of the water storage tank. The transverse movement mechanism includes: a base, a motor, a gear, a rack, a slider and a slide rail. The motor is fixed to the lower side of the base. The gear is installed on the output shaft of the motor. The rack meshing with the gear is installed under the gear. The rack is fixed to the sewage aeration tank. Two sliders are fixed to the lower side of the base. Each slider is slidably installed on a slide rail. The slide rail is fixed to the sewage aeration tank.

[0006] Preferably: The heat end of the semiconductor refrigeration sheet is installed with heat dissipation fins.

[0007] Preferably: Both the heat exchange pipe and the heat dissipation fins are made of copper.

[0010] The beneficial effects of the present utility model are as follows: For the process device for enhancing sewage treatment capacity, during use, the sewage is placed in the sewage aeration tank for aeration treatment, and the organic pollutants in the sewage are decomposed by bacteria. Meanwhile, the air flow is conveyed into the heat exchange tube by the high-pressure blower, and then enters the shunt tube and the conduit. Then, the air flow is discharged into the sewage aeration tank from the air outlet holes. When the weather temperature is relatively high, the semiconductor refrigeration sheet is started to cool the water flow in the water storage tank, and then the cold water is used to cool the air flow passing through the heat exchange tube, and the sewage is cooled by the low-temperature air flow. When the weather temperature is relatively low, the electric heating rod is used to heat the water flow in the heat exchange tube, and the hot water is used to heat the air flow passing through the heat exchange tube, and the sewage is heated by the heated hot air flow, so as to increase the temperature of the sewage, and further keep the water temperature at a temperature with high bacterial activity (15 - 35 °C) to accelerate the decomposition rate of bacteria on the total organic matter in the sewage; after the aeration treatment is completed, the sewage is drained away, and the sludge pump is started.

At the same time, the motor drives the gear to rotate, the rotation of the gear drives the base to move, and the movement of the base drives the sludge cleaning mechanism to move, thereby adjusting the suction position of the sludge cleaning mechanism. In summary, the present utility model is convenient for sewage aeration treatment, and is convenient for adjusting the temperature of the sewage according to the weather temperature, so as to keep the bacteria highly active and increase the decomposition rate of bacteria on organic matter; it is convenient for cleaning the sludge deposited in the sewage.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The following gives specific embodiments.

[0021] See Figures 1 to 6 , in the embodiment of the present invention, a process device for improving sewage treatment capacity includes a sewage aeration tank 1, a temperature-adjusting aeration mechanism 2, a dust filtering mechanism 3, a transverse movement mechanism 4 and a sludge cleaning mechanism 5. A temperature-adjusting aeration mechanism 2 extending into its interior is installed on one side of the sewage aeration tank 1. A dust filtering mechanism 3 is connected to the temperature-adjusting aeration mechanism 2. A transverse movement mechanism 4 is installed on the top of the sewage aeration tank 1. A sludge cleaning mechanism 5 extending to the bottom end inside the sewage aeration tank 1 is installed on the transverse movement mechanism 4. During use, the sewage is placed in the sewage aeration tank 1 for aeration treatment, and the organic pollutants in the sewage are decomposed by bacteria. At the same time, air is introduced into the sewage aeration tank 1 through the temperature-adjusting aeration mechanism 2 to provide sufficient oxygen for the bacteria. In addition, the temperature of the water in the sewage aeration tank 1 can also be regulated through the temperature-adjusting aeration mechanism 2, and the water temperature is maintained at a temperature with high bacterial activity (15-35 °C) to accelerate the decomposition rate of the total organic matter in the sewage by the bacteria. After the aeration treatment is completed, the sewage is drained away, and then the transverse movement mechanism 4 drives the sludge cleaning mechanism 5 to move, and the sludge at the bottom end inside the sewage aeration tank 1 is pumped away through the sludge cleaning mechanism 5, thereby preventing sludge accumulation from reducing the effective volume of the sewage aeration tank 1.

[0022] The temperature-adjustable aeration mechanism 2 includes: a high-pressure blower 201, a water storage tank 202, a shunt pipe 203, a conduit 204, air outlets 205, a heat exchange pipe 206, an electric heating rod 207, a semiconductor refrigeration sheet 208, and a check valve 209. The high-pressure blower 201 and the water storage tank 202 are both placed on the ground. There is water stored in the water storage tank 202. A heat exchange pipe 206 is installed in the water storage tank 202. The high-pressure blower 201 is connected to the heat exchange pipe 206. The heat exchange pipe 206 is connected to the shunt pipe 203. A check valve 209 is installed on the shunt pipe 203. A plurality of conduits 204 inserted into the inner bottom end of the sewage aeration tank 1 are installed on the shunt pipe 203. A plurality of air outlets 205 are provided at the bottom of each conduit 204. The downward setting of the air outlets 205 can prevent the sludge in the sewage from directly falling into the air outlets 205. Through the setting of the check valve 209, the fluid can only flow from the shunt pipe 203 to the conduit 204, and the fluid cannot flow through the shunt pipe 203 from the conduit 204. An electric heating rod 207 is installed in the water storage tank 202. A plurality of semiconductor refrigeration sheets 208 (the cold ends of the semiconductor refrigeration sheets 208 are attached to the water storage tank 202) are installed on the outer side of the water storage tank 202. Heat dissipation fins 2081 are installed at the hot ends of the semiconductor refrigeration sheets 208. The heat at the hot ends of the semiconductor refrigeration sheets 208 is dissipated through the heat dissipation fins 2081 (a fan can also be used to blow air at the hot ends of the semiconductor refrigeration sheets 208 for heat dissipation according to needs). Both the heat exchange pipe 206 and the heat dissipation fins 2081 are made of copper to have good thermal conductivity. The dust filtering mechanism 3 is connected to the air inlet nozzle of the high-pressure blower 201. During use, the air flow is transported into the heat exchange pipe 206 by the high-pressure blower 201, and then the air flow enters the shunt pipe 203 and the conduit 204. Then, the air flow is discharged into the sewage aeration tank 1 from the air outlets 205. When the weather temperature is high, the semiconductor refrigeration sheets 208 are started to cool the water flow in the water storage tank 202, and then the cold water is used to cool the air flow passing through the heat exchange pipe 206, and the sewage is cooled by the low-temperature air flow. When the weather temperature is low, the electric heating rod 207 is used to heat the water flow in the heat exchange pipe 206, and the hot water is used to heat the air flow passing through the heat exchange pipe 206, and the sewage is heated by the heated hot air flow, thereby increasing the temperature of the sewage.

[0023] The dust filtering mechanism 3 includes: an air inlet pipe 301, a filter screen 302, and a brush strip 303. The air inlet pipe 301 is connected to the air inlet nozzle of the high-pressure blower 201. A filter screen 302 is installed in the air inlet pipe 301. A brush strip 303 is rotatably connected to the filter screen 302. During use, the filter screen 302 filters the dust in the air, reducing the dust entering the sewage along with the air flow. After using for a period of time, the brush strip 303 is rotated to brush off the dust accumulated on the filter screen 302.

[0024] The transverse movement mechanism 4 includes: a base 401, a motor 402, a gear 403, a rack 404, a slider 405, and a slide rail 406. The motor 402 is fixed to the lower side of the base 401. A gear 403 is installed on the output shaft of the motor 402. A rack 404 that meshes with the gear 403 is installed below the gear 403. The rack 404 is fixed to the sewage aeration tank 1. Two sliders 405 are fixed to the lower side of the base 401. Each slider 405 is slidably installed on a slide rail 406. The slide rail 406 is fixed to the sewage aeration tank 1. A sludge cleaning mechanism 5 is installed on the base 401. During use, the motor 402 drives the gear 403 to rotate. The rotation of the gear 403 drives the base 401 to move. The movement of the base 401 drives the sludge cleaning mechanism 5 to move, thereby adjusting the suction position of the sludge cleaning mechanism 5.

[0025] The sludge cleaning mechanism 5 includes: a sludge pump 501, a sludge discharge pipe 502, a suction pipe 503, and a sludge inlet pipe 504. The sludge pump 501 is fixed to the base 401. A sludge discharge pipe 502 is installed on the sludge pump 501. A suction pipe 503 that extends to the bottom end inside the sewage aeration tank 1 is installed on the sludge pump 501. A plurality of sludge inlet pipes 504 are provided at the bottom of the suction pipe 503. During use, the sludge pump 501 is started. The sludge enters through the sludge inlet pipe 504, and then the sludge pump 501 discharges the sludge from the sludge discharge pipe 502.

[0026] Working principle: For this process device for enhancing sewage treatment capacity, during use, the sewage is placed in the sewage aeration tank 1 for aeration treatment. The organic pollutants in the sewage are decomposed by bacteria. At the same time, the air flow is conveyed into the heat exchange pipe 206 by the high-pressure blower 201. The air flow then enters the shunt pipe 203 and the conduit 204. Then, the air flow is discharged into the sewage aeration tank 1 from the air outlet holes 205. When the weather temperature is relatively high, the semiconductor refrigeration sheet 208 is started to cool the water flow in the water storage tank 202, and then the cold water is used to cool the air flow passing through the heat exchange pipe 206. The sewage is cooled by the low-temperature air flow. When the weather temperature is relatively low, the electric heating rod 207 is used to heat the water flow in the heat exchange pipe 206, and the hot water is used to heat the air flow passing through the heat exchange pipe 206. The heated hot air flow heats the sewage, thereby increasing the temperature of the sewage, and further keeping the water temperature at a temperature (15 - 35 °C) with high bacterial activity to accelerate the decomposition rate of the total organic matter in the sewage by bacteria. After the aeration treatment is completed, the sewage is drained away. The sludge pump 501 is started. The sludge enters through the sludge inlet pipe 504, and then the sludge pump 501 discharges the sludge from the sludge discharge pipe 502. At the same time, the motor 402 drives the gear 403 to rotate. The rotation of the gear 403 drives the base 401 to move. The movement of the base 401 drives the sludge cleaning mechanism 5 to move, thereby adjusting the suction position of the sludge cleaning mechanism 5.
