A linkage type multi-stage sewage purification device

Abstract

The invention discloses a linkage type multi-grade sewage purification device. The linkage type multi-grade sewage purification device comprises a first-grade purification device and a second-grade purification device, which are connected through a shaft coupler, wherein the first-grade purification device comprises a water flushing seat, a purification assembly, a buffering water storage barrel and a water inlet / outlet valve seat, which sequentially are sleeved from bottom to top; the water flushing seat comprises a limiting flushing barrel which is fixedly mounted at the top end of a power transmission seat; a water flushing mechanism is fixedly mounted on the power transmission seat. According to the linkage type multi-grade sewage purification device, multi-grade purification of sewageis realized through the first-grade purification device and the second-grade purification device; meanwhile, automatic washing of water flow on the purification assembly is realized in a purificationprocess through an impact force of a sealing extruding column; accumulation of impurities on the surface of the purification assembly can be reduced; meanwhile, the utilization time of the purification assembly can be prolonged and the cost is reduced; in the purification process, water purified through the purification assembly is upward squeezed to a water outlet through the sealing extruding column and then is directly discharged from the water outlet; the discharging speed of the filtered water can be increased so that the purification efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of sewage purification and relates to a linkage type multi-stage sewage purification device. Background technique [0002] Sewage treatment is one of the important measures to protect the environment and save water resources. Different treatment methods are adopted for different types of sewage, but most of the treatment process involves the problem of sewage precipitation, which is generally natural precipitation and takes a long time. , and it is not easy to settle completely, and the effect of sewage treatment is not ideal. Therefore, the purification of sewage is realized by filtration. However, during the purification process, the filter component needs to be replaced in time after a few times of filtration due to a layer of sediment attached to the surface. At the same time, during the purification process The purified water flows out slowly, which not only reduces the purification efficiency, but also increases...

[0002] Sewage treatment is one of the important measures to protect the environment and save water resources. Different treatment methods are adopted for different types of sewage, but most of the treatment process involves the problem of sewage precipitation, which is generally natural precipitation and takes a long time. , and it is not easy to settle completely, and the effect of sewage treatment is not ideal. Therefore, the purification of sewage is realized by filtration. However, during the purification process, the filter component needs to be replaced in time after a few times of filtration due to a layer of sediment attached to the surface. At the same time, during the purification process The purified water is relatively slow when it flows out, which not only reduces the purification efficiency, but also increases the purification cost
