Description

Technical field

[0001] The invention belongs to the field of water filtration technology, and more particularly to a non-pump rinsing upflow filter and a water filtration method thereof. Background technique

[0002] Existing urban water supply or other raw water filtration requires a filter, including a pressure filter, a valve filter, an iris filter, and a V-type filter. Regardless of which filter, quartz sand is used as a filter material of the filter layer, and the raw water is used to pass through the filter layer from the upper to the bottom direction, and the sandstone layer of the formation of the filter layer is subjected to a sand. Fine sand, medium sand and coarse sand distribution, due to the uppermost layer of lashes, the minimum, most dense, which causes the impurities that need to be trapped in the raw water, which is basically completely trapped in the uppermost layer of sand, resulting in the most The upper layer of small thickness of the abrasive is saturated in...
