Description

Technical Field

[0001] The utility model belongs to the technical field of micro-oxygen aeration biochemical filter tanks, in particular to a wastewater treatment device of a micro-oxygen aeration biochemical filter tank with a backwashing structure. Background Art

[0002] Micro-aerobic aerated biofilter is an advanced wastewater treatment technology that combines biological treatment with physical filtration to efficiently remove organic matter and suspended solids from wastewater. This device usually includes one or more filters containing biofilms that can operate under low-oxygen or micro-aerobic conditions, which is conducive to the growth of specific microorganisms that can degrade organic pollutants.

[0003] When filtering wastewater through a biofilm filter, impurities in the wastewater will penetrate into the interior of the biofilm filter, causing the biofilm filter to be blocked, affecting the speed of the water flow, and reducing the efficiency of the biofilm filter in treating wastewater. The biofilm filter needs to be cleaned. When cleaning the biofilm filter, backwashing is used to clean the biofilm filter through water flow. The existing backwashing structure does not have the effect of collecting the impurities after cleaning. The cleaned impurities are discharged into the interior of the filter tank with the water flow, which is inconvenient to clean the impurities. The problem with the above technology is that when the biofilm filter is backwashed, the impurities will be discharged into the interior of the filter tank, which is inconvenient to collect and treat the impurities.

The water pump discharges water into the interior of the water plate 2a through two water inlet pipes 2d, and the water flows through multiple nozzles 2c to the wastewater filter 1b to clean the wastewater filter 1b. The impurities cleaned out of the wastewater filter 1b are collected by the collecting component 5. In order to facilitate the cleaning of the impurities after cleaning, the collecting component 5 includes a collecting box 501, a backwash filter 502 and a bottom plate 503.

Then, by starting the cylinder 7, the output end of the cylinder 7 drives the connecting plate 2b to move upward, and the process of the connecting plate 2b moving upward drives the water plate 2a and the collecting box 501 to move upward, so that the water plate 2a and the collecting box 501 are out of contact with the wastewater. In order to keep the water plate 2a in close contact with the wastewater filter 1b, the front and rear sides of the right side of the water plate 2a are fixedly connected with the limiting rods 9, the right side of the front limiting rod 9 is slidably connected to the front side of the left side of the inside of the wastewater filter 1b, and the surface of the rear limiting rod 9 is slidably connected to the rear side of the left side of the inside of the wastewater filter 1b.

[0025] The working principle of this utility model:

[0026] When treating wastewater, the air inlet pipe 1c is connected to the air pump, and the gas is discharged to the wastewater filter 1b through the air inlet pipe 1c and multiple aeration pipes 1d. The wastewater is discharged into the right side of the box body 1a, and then filtered through the wastewater filter 1b and discharged into the left side of the water tank. The filtered wastewater is collected and treated through the drain port 3 on the left. When the wastewater filter 1b needs to be cleaned, the wastewater is discharged from the inside of the box body 1a through the drain port 3 on the left. The cylinder 7 is started, and the output end of the cylinder 7 drives the connecting plate 2b to move downward. During the downward movement of the connecting plate 2b, the water plate 2a and the collecting box 501 are driven downward. The right side of the water plate 2a is in close contact with the left side of the wastewater filter 1b. During the movement of the collecting box 501, the bottom plate 503 is driven downward. During the downward movement of the bottom plate 503, the top plate 4 is driven to move to the right. During the rightward movement of the top plate 4, multiple aeration pipes 1d and the air inlet pipe 1c are driven to move to the right. In the process of multiple aeration tubes 1d moving backward, the two connecting rods 601 are driven to move rightward. In the process of the two connecting rods 601 moving rightward, the two stabilizing springs 603 are driven to deform, so that the two connecting rods 601 generate a leftward thrust, thereby driving the multiple aeration tubes 1d to push leftward. The multiple aeration tubes 1d drive the collecting box 501 to push leftward, so that the collecting box 501 is in close contact with the wastewater filter 1b. After the bottom of the water plate 2a is aligned with the bottom of the wastewater filter 1b, the two water inlet pipes 2d are connected to the water pump, and the water pump discharges water into the interior of the water plate 2a through the two water inlet pipes 2d. The water flow is sprayed toward the wastewater filter 1b through the multiple nozzles 2c to clean the wastewater filter 1b. In the process of the water flow cleaning the wastewater filter 1b, the impurities are driven out of the interior of the wastewater filter 1b, and the cleaned water flow is filtered through the backwash filter 502, so that the impurities fall into the interior of the collecting box 501, thereby collecting the cleaned impurities.
