The invention provides a combined filtering system, and relates to the technical field of water treatment. The system comprises a liquid inlet main pipe and at least one filtering device communicatedwith the liquid inlet main pipe; and the filtering device comprises a primary filter, a security filter and a sand-water separator which are sequentially arranged in the liquid flowing direction. Theat least one filtering device is used for filtering the liquid in the liquid inlet main pipe, the filtering device comprises the primary filter, the security filter and the sand-water separator, the primary filter is combined with the security filter to make the security filter refilter a liquid filtered by the primary filter, so the filtering precision of the system is remarkably higher than thatof a system independently using the primary filter; and the sand-water separator can filter and separate the filter particles during backwashing of the primary filter, so that the separated filter particles can be conveniently collected and repeatedly utilized, and the operation cost is saved.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to a combined filter system. Background technique [0002] With the shortage of water resources, the treatment and reuse of water resources has become a necessary means. The most commonly used water treatment method is to filter through filtering devices. [0003] The more commonly used filter devices are sand canister filters and ultrafiltration membrane filters; among them, the quartz sand particles filled in the sand canister filters have a large gap and low filtration accuracy, which cannot meet the requirements; ultrafiltration membrane filtration The filtration accuracy of the filter is very high, but the cost of replacing the filter membrane is very high, and the filter membrane has high requirements for the operating environment temperature. [0004] With the advancement of filtration technology, a filter with porous granular materials has appeared, and its filtrati...
