[0002] Among numerous water treatment links, filtration is the key link to remove impurities, suspended solids, colloids and other pollutants in water. Traditional single-medium filter, such as using only quartz sand or activated carbon as filter medium, can play a filtering role to some extent, but its filtering effect is limited for complex composition of sewage. For example, when treating industrial wastewater containing various organic pollutants, heavy metal ions and different particle size suspended solids, single medium is difficult to meet the requirements of efficient adsorption, interception and conversion of different pollutants. Moreover, traditional filter is prone to problems such as filter material hardening and incomplete backwashing during filtration process, resulting in gradual reduction of filtration efficiency, shortening of equipment service life, frequent replacement of filter material or equipment maintenance, increasing water treatment cost and complexity of operation and management. Therefore, some multi-medium filters appear in the market.
