Problems solved by technology
[0002] In daily domestic water, there are often many impurities and some harmful substances in tap water, and some can smell some odors. Therefore, it is necessary to purify the water before using tap water, so as to meet the daily reference standards; but During the purification process, if some filtered impurities are not properly disposed of, they will cause secondary pollution of the water source, and may also cause pollution of the water pipeline.

Embodiment Construction
[0038] The present invention will be further described below in conjunction with the accompanying drawings.
[0039] as attached Figure 1-12: A kind of counter-current type water purification filtration system, comprising a water flow channel 1; the water flow channel 1 is in a broken line shape, and the flow direction of the water flow is uphill and circulates along the water flow channel 1; like this, the purified water can flow out to the upper layer, and the impurities It is trapped in the lower layer, and impurities can also be avoided from polluting the purified water; a filter structure 2 is provided at the folding line end of the middle part of the flowing water channel 1; Back-end ultrafiltration water outlet; the backwash water structure 3 at the water outlet end of the filter structure 2 is connected to the inside of the filter structure 2 to form a loop cleaning structure 4 . When the water passes through the water flow channel 1, the impurities in the water are ...

The invention discloses a reverse-flow type water purifying and filtering system and a filtering method thereof. The reverse-flow type water purifying and filtering system comprises a water flow channel; the water flow channel is in a broken line shape, and water flow flows in an uphill mode and flows along the water flow channel; a filtering structure is arranged at the middle broken line end ofthe water flow channel; water entrainment and deslagging are carried out at the front end of the filtering structure, and ultrafiltration is carried out at the rear end of the filtering structure to discharge water; a backflushing structure at the water outlet end of the filtering structure is communicated with the interior of the filtering structure to form a loop-back cleaning structure. According to the reverse-flow type water purifying and filtering system and the filtering method thereof provided by the invention, water can be effectively purified, and filtered impurities can be effectively cleaned out.
Description
technical field [0001] The invention relates to the field of water purification treatment, in particular to the field of water purification and filtration. Background technique [0002] In daily domestic water, there are often many impurities and some harmful substances in tap water, and some can smell some odors. Therefore, it is necessary to purify the water before using tap water, so as to meet the daily reference standards; but During the purification process, if some filtered impurities are not properly disposed of, they will cause secondary pollution of the water source, and may also cause pollution of the water pipeline. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a counter-flow water purification filtration system and its filtration method, which can effectively purify water and effectively remove filtered impurities. [0004] Technical scheme: in order to achie...
