Description

Stirred sand filter activated carbon filter tank

This creation is an agitated sand filter activated carbon filter tank, especially a stirred sand filter activated carbon filter tank that can stir the inner filter material.

In sewage treatment, it will first go through biological or chemical treatment procedures, and then through sedimentation to remove the heavier sludge deposits in the water. If the quality of the treated water still fails to meet the discharge standard, then It will be filtered to remove the finer suspended solids and impurities in the water to be treated, and perform decolorization, deodorization, and chemical oxygen demand reduction (Chemical Oxygen Demand, COD) treatments.

Nowadays, a sand filter bucket is used to filter the water to be treated. The top and bottom of the sand filter bucket are respectively provided with an upper runner pipe and a lower runner pipe. The upper runner pipe can be connected to a sewage source and the lower runner The pipe can be connected to a drainage water storage tank. The inside of the sand filter bucket is filled with filter materials such as gravel, sand, silica sand, activated carbon particles, and resin particles according to the difference in the material to be filtered, and can penetrate the filter material to Perform filtration of the water to be treated, wherein the sand filter bucket has the functions of positive filtration and backwashing.

In the positive filtering operation mode, the operator can pressurize through the external motor, and the water to be treated can pass through the upper runner pipe to enter the sand filter bucket, and the water to be treated can pass through the filter material from top to bottom. Filtration, the filtered water will flow into the drainage water storage tank through the lower runner pipe, and when the water quality of the filtered water is not good, the backwashing operation of the sand filter tank is required. At this time, the operator will lower the runner The pipe is connected to a clean water source and pressurized by an external motor, so that the clean water enters the sand filter bucket from the bottom runner pipe. The pollutants will flow into the upper flow pipe along with the water flow and be discharged into the original sewage adjustment tank.

The sand filter buckets on the market today only use the pressure of an external motor to pressurize the purified water, and use reverse osmosis to remove the contaminants attached to the filter material by water pressure. However, the density of the filter materials such as silica sand, activated carbon, and resin is high. And if the water to be treated is treated by a chemical coagulation process, the water often contains heavy metals and viscous substances, which will cause the adsorption of silica sand, activated carbon, resin and other filter materials to become saturated and agglomerate, resulting in reverse osmosis relying solely on water pressure Backwashing cannot effectively infiltrate and remove the contaminants on the filter material. At this time, the operator needs to replace all the filter materials to ensure good quality of the filtered water.

However, replacing the filter material not only consumes the cost of the filter material itself, but also requires extra manpower to clean the filter material in the sand filter bucket. It also requires a crane to pour the filter material from the top of the sand filter bucket into the filter material, so frequent Replacing the filter material will increase the cost of the filtering operation, and the utilization rate of the filter material will be low, resulting in waste.

In addition, when sewage enters the sand filter bucket, the filter materials located at the top and bottom of the sand filter bucket will absorb more impurities in the sewage. The resulting resistance will increase, resulting in a decrease in the amount of water that can be processed under the same operating time, which not only reduces the efficiency of the processing operation, but also consumes the same labor costs. Therefore, the operator will increase the amount of sewage to enter the tank body. The current water pressure can force the sewage to flow through the filter material. However, if the water pressure is increased, it will also cause additional electricity costs.

The main purpose of this creation is to provide an agitated sand filter activated carbon filter tank, which hopes to improve the inability to effectively clean the filter material when the current sand filter tank is backwashed, resulting in an increase in the cost of filtering operations, and due to the utilization rate of the filter material It is low and wasteful, and causes problems such as extra electricity costs.

In order to achieve the purpose of the previous disclosure, the agitated sand filter activated carbon filter tank of this creation contains: A tank body with a filtering space formed inside, a feed valve capable of opening and closing is formed on the top of the tank body, a discharge valve capable of opening and closing is formed on the side wall of the tank body, the feed valve And the discharge valve can respectively communicate with the filter space and the outside of the barrel body; A first pipe body, which is arranged in the barrel body, and has a first flow pipe formed at one end, the first flow pipe extends into the filtering space, and the other end of the first pipe body is connected to an external water source; A second pipe body, which is arranged in the barrel body, and has a second flow pipe formed at one end, the second flow pipe extends into the filtering space, the other end of the second pipe body is connected to an external water source, the The first flow tube and the second flow tube are respectively located on opposite sides of the barrel body; and A stirring member comprising a drive module and a stirring structure, the drive module being arranged on the top of the tank body, one end of the stirring structure is connected to the drive module, and a plurality of disturbances arranged at intervals are formed on the other end The plurality of disturbance elements are located in the filtering space.

The filter space of the tank body of the agitated sand filter activated carbon filter tank of the original creation can be filled with filter materials. The first tube body can introduce sewage into the tank body and can export the backwashed water. The second tube Physical energy can export filtered water and can introduce water for backwashing. The stirring member can turn the filter material in the tank body. Among them, the agitated sand filter activated carbon filter tank has the following advantages: 1. The filter material can be effectively cleaned: the operator can drive the stirring structure to rotate in the filter space by controlling the drive module of the stirring member. When the sand filter activated carbon filter tank is used for backwashing, in addition to pressurizing water through an external motor to flush the filter material in the filter space, it can also be stirred by the disturbing member to cause the filter material to rub against each other. Furthermore, the pollutants adsorbed on the filter material can be effectively removed. 2. Can save operation cost: As mentioned above, when the filter material absorbs more pollutants, the filter material can be effectively cleaned by using the stirring structure to stir the filter material during backwashing operation to prolong the service life of the filter material. This can make full use of the filter material in the sewage filtering operation, and extend the interval between each replacement of the filter material, avoiding the waste of the filter material. In addition to saving the cost of the filter material itself, it can also save the manpower required to replace the filter material. The cost of material resources. 3. Energy saving: during sewage treatment operations, if the filter material in the filter space absorbs more impurities and causes greater resistance to the sewage, the operator can control the operation of the mixing structure, which will cause more The filter material with high resistance is evenly distributed in the filter space, and will not accumulate on the top and bottom of the filter space, thereby avoiding additional strengthening of the water pressure when the sewage enters the water, and can effectively save energy.
