In recent years, with the increasingly prominent problem of water source pollution, the application of advanced treatment technology of drinking water with activated carbon as a core is more and more extensive. In this technique, activated carbon plays an important role as an adsorption medium. However, the types of domestic activated carbon are various at present, and the performance difference is large, so that the selection of the activated carbon in many water plants is blindness. The price of the active carbon is expensive, the dosage is large, and the conditions of short use period and frequent replacement of the active carbon can occur if the type is not selected properly, so that the operation cost is greatly increased. And the common active carbon has the characteristics of high ash content, small pore volume, wide micropore distribution, small specific surface area, poor adsorption selectivity and the like, and has limited adsorption removal effect on pollutants due to the limitations of surface functional groups and electrochemical properties, so that the common active carbon can not meet the requirements of domestic and foreign markets.
The existing activated carbon filter element has serious activated carbon black water, and has low dirt-removing power to sewage due to the contact time segment between particles and water; meanwhile, the conventional activated carbon filter element uses rubber powder to bond activated carbon particles, so that the adsorption pore diameter of part of activated carbon is inevitably blocked, and the adsorption capacity of the activated carbon is weakened.
