Description

Technical Field

[0001] The utility model relates to the technical field of drinking water purification, in particular to a biological activated carbon drinking water treatment device. Background Art

[0002] The biological activated carbon method is a wastewater biological treatment process that uses activated carbon as a carrier to form a biofilm on the carbon surface during the wastewater treatment process, resulting in a synergistic effect of activated carbon adsorption and microbial oxidation and decomposition of organic matter. This method improves the removal rate of organic matter in wastewater, increases stability to toxins and load changes, improves sludge dewatering and digestion performance, and extends the service life of activated carbon. It is a new biological treatment technology that mainly uses biological treatment and also has the characteristics of physical and chemical treatment. As the main deep treatment process of water plants, the biological activated carbon process is becoming more and more widely used.

[0003] However, after a period of operation, the water quality treatment effect of the biological activated carbon pool is reduced due to the adsorption capacity problem of the biological activated carbon. Therefore, the replacement of the biological activated carbon needs to be considered. In addition, the efficiency of the use of biological activated carbon is limited by the usage method and the structure of the water treatment pool, resulting in the inability to fully utilize the biological activated carbon. Utility Model Content

[0004] In order to solve the problem that biological activated carbon cannot be fully utilized and the problem of a method for conveniently replacing biological activated carbon, the utility model provides a biological activated carbon drinking water treatment device.

[0006] A biological activated carbon drinking water treatment device includes a purification tank and an activated carbon tank. The activated carbon tank is arranged in the purification tank, and the purification tank is inclined on the ground. Baffles are arranged in the purification tank, and the baffles are arranged vertically at intervals in the purification tank. An aeration pipe is arranged in the activated carbon tank.

[0007] The activated carbon tank is used to store biological activated carbon. When water flows through, the biological activated carbon adsorbs and purifies the water quality. The purification tank is set on the ground at an angle, which is conducive to the water flowing from top to bottom through the purification tank and the activated carbon tank. The baffle is used to guide the direction of water flow and at the same time helps to increase the length of the path through which the water flows, which is conducive to the full utilization of biological activated carbon. The aeration pipe is used to aerate the activated carbon tank to increase the oxygen content in the activated carbon tank.

[0008] Furthermore, the baffle is divided into a high-position plate and a low-position plate, and the high-position plate and the low-position plate are arranged alternately at intervals. A sealing top plate is installed on the top of the baffle, the top of the high-position plate is close to the sealing top plate, and the bottom of the high-position plate is suspended in the activated carbon tank. The top of the low-position plate is arranged below the sealing top plate and forms a gap with the sealing top plate, and the bottom of the low-position plate is close to the bottom plate of the purification tank.

[0009] The high-level plates and the low-level plates are arranged alternately to guide the water flow to flow continuously from top to bottom and from bottom to top. Each time the water flows alternately from top to bottom and from bottom to top, it passes through the activated carbon tank for filtration, adsorption and purification to improve the degree of water purification.

[0010] Furthermore, the vertical cross-section of the baffle is in a broken line shape, the sealing top plate is in a semi-cylindrical shape and its two ends are respectively mounted on two adjacent high-position plates, and the bottom plate of the purification tank is arranged at an angle.

[0018] Furthermore, a barrier net is provided on the activated carbon tank, and the pore size of the barrier net is smaller than the particle size of the activated carbon in the activated carbon tank.

[0019] The barrier net is used to prevent the activated carbon in the activated carbon tank from being washed away by water.

[0020] Furthermore, the aeration pipe is provided with air outlets at intervals, one end of the aeration pipe is connected to a blower, and a one-way air outlet valve is provided at the air outlet.

[0021] The one-way air outlet valve is used to prevent water from flowing back into the aeration pipe and affecting the operation of the aeration blower.

[0022] In summary, the present invention has the following beneficial technical effects:

[0023] 1. The activated carbon tank is used to store biological activated carbon. When water flows through, the biological activated carbon adsorbs and purifies the water quality. The purification tank is tilted on the ground, which is conducive to the water flowing from top to bottom through the purification tank and the activated carbon tank. The baffle is used to guide the flow of water and at the same time help to increase the length of the path through which the water flows, which is conducive to the full utilization of biological activated carbon. The aeration pipe is used to aerate the activated carbon tank to increase the oxygen content in the activated carbon tank.

[0024] 2. The high-level plates and low-level plates are arranged alternately to guide the water flow to flow continuously from top to bottom and from bottom to top. Each time the water flows alternately from top to bottom and from bottom to top, it passes through the activated carbon tank for filtration, adsorption and purification to improve the degree of water purification.
