Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment, and in particular to a micro-flocculation fiber disc filter device. Background Technology

[0002] Currently, a large amount of wastewater (containing a large amount of suspended solids) is generated in industrial and agricultural production. Wastewater needs to be purified before discharge. In order to adsorb and treat the suspended solids in wastewater, patent publication document CN213977272U discloses an air flotation sedimentation tank that can treat wastewater. The air flotation sedimentation tank shown in this structure uses air flotation to purify and remove pollutants from wastewater. Because this air flotation sedimentation tank needs to continuously pump high-pressure gas into the water body during purification, the energy consumption of this air flotation sedimentation tank is very high when treating water. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a micro-flocculation fiber rotary filter device. By using flocculation baffles and filter plates, it removes suspended particles and algae from wastewater while it is in a flowing state, thus purifying the wastewater. Furthermore, no aeration is required during the wastewater treatment process, resulting in relatively low energy consumption throughout the entire process.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A micro-flocculation fiber rotary filter device includes a tank body, in which a first processing chamber, a second processing chamber, and a third processing chamber are disposed. The second processing chamber is in communication with the first and third processing chambers. The device also includes a plurality of flocculation baffles and a plurality of filter plates. The flocculation baffles are disposed in the second processing chamber, and adjacent flocculation baffles are not in contact with each other. The filter plates are disposed in the third processing chamber, and adjacent filter plates are parallel and not in contact with each other.

[0006] The working process of this micro-flocculation fiber rotary filter device is as follows: first, the sewage enters the first treatment chamber, then the second treatment chamber, and finally the third treatment chamber.

[0007] The wastewater treatment process of this micro-flocculation fiber rotary filter device is as follows: First, PAC (aluminum chloride treatment agent) is added to the wastewater when it enters the first treatment chamber. Then, PAM (polyacrylamide) is added. At this point, suspended particles in the wastewater begin to flocculate. The flocculated wastewater then flows to the second treatment chamber, where it comes into contact with flocculation baffles. Suspended particles adhere to these baffles, providing initial purification. After purification, the wastewater flows further to the filter plates. Algae and other particles in the wastewater are further adsorbed by the filter plates and eventually leave the tank.

[0008] Therefore, in this micro-flocculation fiber rotary filter device, by using flocculation baffles and filter plates, suspended particles and algae are removed from the wastewater in a flowing state, thus purifying the wastewater. Moreover, no aeration is required during the wastewater treatment process, and the energy consumption of the entire process is relatively low.

[0009] Specifically, in this device, the filter is a fiber disc filter.

[0010] Optionally, the flocculation baffle is a zigzag-shaped flocculation baffle, and the flocculation baffle is disposed on the top or bottom of the tank.

[0011] The purpose of using zigzag-shaped flocculation baffles is to allow suspended particles in the wastewater to adhere to the flocculation baffles as much as possible.

[0012] Optionally, it also includes a stirring paddle, which is rotatably disposed inside the first processing chamber, and a drive motor is disposed outside the tank body, the drive motor cooperating with the stirring paddle.

[0013] Specifically, the drive motor drives the agitator to rotate, and the rotation of the agitator enables the suspended particles in the first processing chamber to fully react with the reagent, and then fully flocculate after the reaction.

[0014] Optionally, it also includes an inlet pipe and an outlet pipe, both of which are installed on the tank body. The inlet pipe is connected to the first processing chamber, and the outlet pipe is connected to the third processing chamber.

[0015] Wastewater enters the first treatment chamber through the inlet pipe, and after treatment, it enters the outlet pipe through the third treatment chamber.

[0016] Optionally, the tank body is connected to a sludge discharge pipe, which is connected to the second processing chamber.

[0017] The purpose of the sludge discharge pipe is to discharge sludge. After suspended particles adhere to the flocculation baffles, they will eventually fall to the bottom of the tank and settle as sludge.

[0018] Optionally, a cleaning pipe is provided inside the third processing chamber, and a suction pump is connected to the cleaning pipe. The suction pump is located outside the tank.

[0019] The inlet of the cleaning tube is located on one side of the filter. The suction pump is connected to the cleaning tube. When the suction pump is turned on, it can remove the dirt attached to the filter, thereby cleaning and regenerating the filter.

[0020] Optionally, the filter is a disc-shaped filter.

[0021] Optionally, the first processing cavity and the third processing cavity are located on both sides of the second processing cavity.

[0022] The beneficial effects of this utility model are: by using flocculation baffles and filter sheets, suspended particles and algae are removed from the sewage in a flowing state, thus purifying the sewage. Moreover, no aeration is required during the sewage treatment process, and the energy consumption of the entire process is relatively low. Attached Figure Description

[0031] The working process of this micro-flocculation fiber rotary filter device is as follows: first, the sewage enters the first treatment chamber 301, then the second treatment chamber 302, and finally the third treatment chamber 303.

[0032] The wastewater treatment process of this micro-flocculation fiber rotary filter device is as follows: First, PAC (aluminum chloride treatment agent) is added to the wastewater when it enters the first treatment chamber 301. Then, PAM (polyacrylamide) is added. At this point, suspended particles in the wastewater begin to flocculate. The flocculated wastewater then flows to the second treatment chamber 302, where it comes into contact with the flocculation baffles 6.
