[0002] With the rapid development of our country economy and the acceleration of urbanization, water pollution problem is increasingly serious. The increasing discharge of industrial wastewater, domestic sewage and the like makes the originally good water quality water resources be seriously affected, and causes great threat to ecological environment and human health. In order to protect and improve water environment quality, reduce the occurrence frequency of water pollution accidents, improving sewage treatment efficiency becomes the urgent matter.

[0003] The working of the activated carbon filter is completed through activated carbon, and the activated carbon particles have very many micropores and huge specific surface area, and have very strong physical adsorption capacity. Water passes through activated carbon, and organic pollutants in water are effectively adsorbed by activated carbon. In addition, the non-crystalline part of the surface of activated carbon has some oxygen-containing groups, so that the organic pollutants in the water passing through the activated carbon are effectively adsorbed by the activated carbon. The activated carbon and the filter screen will be attached with a large amount of impurities on the surface in long-term use, resulting in the decline of the filtering effect. However, since the activated carbon plate and the filter screen are installed in the box body, they are inconvenient to disassemble and clean. SUMMARY

[0004] The utility model discloses a sewage treatment device with active carbon step -by -step filtration structure to solve the problem in the background art.

[0005] To achieve the above object, the utility model provides the following technical scheme: a sewage treatment device with active carbon step -by -step filtration structure, including base, the top of base is provided with bottom cylinder, the bottom of bottom cylinder is provided with middle cylinder, the top of middle cylinder is provided with upper cylinder, the top of upper cylinder is provided with connecting seat, the inside of bottom cylinder is provided with fine filter screen, the inside of middle cylinder is provided with mounting assembly, the inside of upper cylinder is provided with coarse filter screen, still include:

[0006] The water inlet pipe for discharging sewage into the upper cylinder is mounted on the outer side of the connecting seat, and the outer side of the connecting seat is further provided with a flushing assembly and a spraying assembly for flushing and cleaning the inside of the bottom cylinder, the upper cylinder and the mounting assembly.

[0007] Preferably, the mounting assembly includes a mounting seat fixedly installed in the inside of the middle cylinder, and the inside of the mounting seat is provided with an activated carbon plate.

[0008] Preferably, the bottom of the coarse filter screen is fixedly installed on the top of the activated carbon plate.

[0009] Preferably, the flushing assembly includes a connecting pipe installed on the outside of the connecting seat, a vertical pipe provided on the outside of the connecting pipe, a plurality of rotary joints provided on the outside of the vertical pipe, and a nozzle provided on the outside of the rotary joints.

[0010] Preferably, the nozzles are tilted and arranged in a ring array outside the rotary joint.

[0011] Preferably, the spray assembly includes a spray pipe disposed inside the middle cylinder, and a rinsing head is disposed at the bottom of the spray pipe.

[0012] Preferably, a support rod is provided between the middle cylinder and the base, and a drain pipe is provided on the outer side of the bottom cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a coarse filter to initially filter wastewater. The filtered wastewater then flows downwards into a middle cylinder for secondary filtration using activated carbon plates. The wastewater then passes through a fine filter for further filtration. When cleaning of the filter and activated carbon plates is required, water is supplied to the vertical pipe via a connecting pipe. The water flow is delivered to the spray nozzles via a rotary joint. The impact force of the water flow drives the spray nozzles and rotary joints, which are equipped with a cyclone mechanism, to rotate, thus enabling a thorough cleaning of the filter. A spray pipe connected to the lower part of the connecting pipe supplies water to a rinsing head, which is used to rinse the activated carbon plates. Attached Figure Description
