Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an air flotation and sedimentation integrated sewage treatment device. Background Art

[0002] Flotation is a type of sewage treatment equipment that allows suspended particles to float and then separate from sewage. It is used to effectively treat industrial and domestic sewage. Flotation is a water treatment technology that is mainly used to remove suspended matter and grease from water. This process usually involves injecting air into the water to form tiny bubbles. These bubbles will attach to suspended particles or oil droplets, reducing their density so that they float to the surface of the water and are then removed by equipment such as scrapers. Integrated treatment can achieve faster processing speeds and higher processing capacity.

[0003] The exhaust device of the traditional flotation device is set separately, which causes the generated bubbles to mix unevenly with the sewage, and then causes the sewage to have less bubbles far away from the bubble generation point, thus affecting the effect of sewage treatment.

The observation window 102 allows the operator to monitor the internal situation of the box 101 in real time. The stirring assembly 205 in the reaction unit 200 is driven by the driving motor 204 to ensure uniform mixing. The air pump 203 is used to inject air to form tiny bubbles, which promote the floating of pollutants after combining with the bubbles, thereby realizing the flotation process. The electric slide rail 301 and the scraper 305 of the cleaning unit 300 are used together to automatically remove the deposited sludge, optimize the sewage treatment process, reduce the need for manual intervention, and improve the reliability and efficiency of the system.

[0033] Among them, a partition 215 is fixedly connected to the middle of the inner wall of the reaction tank 201.

The driving system of the stirring component 205 adopts a structure of an active bevel gear 207 and a driven bevel gear 206, which not only improves the transmission efficiency, but also reduces the noise and maintenance cost during operation. During the stirring process, the water flow will drive the propeller 205d to rotate, thereby improving the effect of breaking up the water flow.

[0035] During use, firstly, wastewater is added into the reaction tank 201 through the feed pipe 209, and then the drive motor 204 is started to drive the stirring assembly 205 to rotate through the active bevel gear 207 and the driven bevel gear 206, and then flocculant is added into the wastewater through the feed pipe 210, and then the air pump 203 is started to exhaust the wastewater through the exhaust hole 205c. During the exhaust process, the wastewater can be stirred, thereby improving the mixing effect and accelerating the purification efficiency. During stirring, the propeller 205d can increase the effect of breaking up the sewage. After the mixing is completed, the filtered wastewater is discharged into the lower half of the reaction tank 201 through the second solenoid valve 216. When it is discharged to a certain extent, the wastewater with pollutants is discharged to the upper surface of the filter plate 103 for filtration, and then the electric telescopic rod 304 is started to push the scraper 305 to fit the filter plate 103, and cooperate with the electric slide rail 301 to push the pollutants out of the box 101, thereby achieving the improvement of the purification effect, and at the same time, the stirring and aeration devices are mixed together, which reduces the volume of the device and improves the processing efficiency.
