Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an anti-clogging activated carbon adsorption tower for wastewater treatment. Background Art

[0002] Wastewater refers to the general term for water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as primary rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards of purification after primary pollution. Wastewater treatment is the use of physical, chemical and biological methods to treat wastewater, purify wastewater, reduce pollution, and achieve wastewater recovery and reuse, and make full use of water resources. Some wastewater is treated through activated carbon adsorption towers.

[0003] However, in the process of using activated carbon adsorption tower to treat wastewater, some activated carbon cannot be fully utilized, resulting in a certain amount of activated carbon being wasted during the investment process. At the same time, the existing filter disc is easily clogged during the long filtration process, resulting in abnormal water output, which in turn affects the normal use of the activated carbon adsorption tower. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides an anti-clogging activated carbon adsorption tower for wastewater treatment, which solves the problems in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A blockage-resistant activated carbon adsorption tower for wastewater treatment comprises an adsorption tower body, a U-shaped plate is fixedly mounted on the top of the adsorption tower body, a rotating shaft is mounted on the top of the U-shaped plate through a rotating mechanism, a brush is fixedly mounted on the surface of the rotating shaft, a filtering mechanism is provided on the inner wall of the adsorption tower body, a backwash water pipe is provided on one side of the adsorption tower body, an inclined plate is fixedly mounted on the inner wall of the adsorption tower body, a guide tube is fixedly mounted on one side of the inclined plate, a mounting plate is fixedly mounted on the surface of the adsorption tower body, a reflux mechanism is provided on one side of the mounting plate, and an ejector is provided inside the guide tube.

[0007] Preferably, the rotating mechanism includes a motor fixedly mounted on the top of the U-shaped plate, a rotating rod fixedly mounted on the output end of the motor, a reducer provided at one end of the rotating rod, and a bottom of the reducer and one end of the rotating shaft are fixedly mounted.

[0008] Preferably, the filtering mechanism comprises a fixing bracket fixedly mounted on the inner wall of the adsorption tower body, and a filter disc is fixedly mounted on one side of the fixing bracket.

[0009] Preferably, the reflux mechanism includes a reflux pump fixedly mounted on one side of the mounting plate, a water inlet pipe is provided on the top of the reflux pump, and a reflux pipe is provided on one side of the reflux pump.

[0010] Preferably, a water inlet is provided at one end of the water inlet pipe, and a valve is provided on the surface of the return pipe.

[0011] Preferably, a mud discharge pipe is provided at the bottom of the adsorption tower body, and a water outlet weir is provided on the surface of the adsorption tower body.

[0012] Preferably, the number of the fixing brackets and filter discs is three and they are arranged in an array, and the number of the inclined plates is two and they are arranged symmetrically.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The high-pressure water flow generated by the ejector is mixed with the activated carbon, and the guide tube guides the wastewater and activated carbon to fully contact, thereby increasing the contact area and contact time between the activated carbon and the pollutants in the wastewater, and significantly improving the adsorption efficiency. By setting two sets of inclined plates, the activated carbon particles slide to the bottom along the inclined plates under the action of gravity and the angle of the inclined plates, effectively preventing the activated carbon from flowing out with the effluent. This separation method not only ensures the effluent quality, but also makes full use of the unsaturated activated carbon.

[0015] 2. By starting the reflux pump, the reflux pump draws the activated carbon at the bottom of the adsorption tower body through the reflux pipe and mixes it with the new incoming water. This not only makes full use of the unadsorbed saturated activated carbon and reduces the amount of activated carbon added, but also improves the efficiency and economy of wastewater treatment. When the wastewater adsorbed by the activated carbon passes through the filter disc, the remaining small amount of activated carbon particles will be retained on the filter disc, thereby achieving deep treatment of the wastewater. By setting up a backwash water pipe, in order to avoid clogging of the filter disc, when a certain amount of activated carbon particles accumulates on the filter disc, the filter disc can be backwashed through the backwash water pipe to remove the accumulated activated carbon, thereby ensuring the water quality and the normal use of the filter disc. The brush is driven by the motor to rotate, so that the impurities on the surface of the filter disc can be cleaned, and further anti-clogging is performed, thereby achieving the purpose of making full use of the activated carbon and facilitating the cleaning of the filter disc. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] During use: When using the anti-clogging activated carbon adsorption tower for wastewater treatment, the wastewater is transported to the interior of the adsorption tower body 1 through the water inlet 18 and the water inlet pipe 15, and the ejector 17 is started so that the high-pressure water flow generated by the ejector 17 is mixed with the activated carbon. At the same time, the guide tube 12 guides the wastewater and the activated carbon to fully contact, thereby increasing the contact area and contact time between the activated carbon and the pollutants in the wastewater, and significantly improving the adsorption efficiency. By setting two sets of inclined plates 11, the activated carbon particles slide to the bottom along the inclined plates 11 under the action of gravity and the angle of the inclined plates 11, effectively avoiding the activated carbon from flowing out with the effluent. This separation method not only ensures the quality of the effluent, but also enables the unsaturated activated carbon to be fully utilized. By starting the reflux pump 14, the reflux pump 14 extracts the activated carbon at the bottom of the adsorption tower body 1 through the reflux pipe 16 and mixes it with the new inlet water. The combination not only makes full use of the unabsorbed saturated activated carbon, reduces the amount of activated carbon added, but also improves the efficiency and economy of wastewater treatment. When the wastewater adsorbed by the activated carbon passes through the filter disc 9, the remaining small amount of activated carbon particles will be trapped on the filter disc 9, thereby realizing deep treatment of the wastewater. By setting up a backwash water pipe 10, in order to avoid clogging of the filter disc 9, when a certain amount of activated carbon particles accumulates on the filter disc 9, the filter disc 9 can be backwashed through the backwash water pipe 10 to remove the accumulated activated carbon, thereby ensuring the water quality and the normal use of the filter disc 9.
