Problems solved by technology

[0005] Activated carbon can effectively remove free chlorine in water and can effectively absorb organic pollutants such as color, odor, pesticides, insecticides, detergents, aromatic compounds, and disinfection by-products in water. The disadvantage lies in the surface layer of activated carbon. A large amount of organic matter adsorbed becomes a breeding ground for bacteria, which easily leads to excessive bacterial content in the effluent, resulting in short service life and bacterial growth, and the removal effect of activated carbon on heavy metal ions in water is not good
The disadvantage of this invention is that only relatively mature filter materials on the market can be used for simple blending and extrusion, because some materials have defects in their own use, such as KDF has a large specific gravity, and there are certain problems in the uniformity of blending and dispersion , and there is no obvious effect when the dosage is small, and the water purification effect will be affected

Abstract

The invention relates to a carbon rod filter cartridge, in particular to a multifunction carbon rod filter cartridge and a manufacturing method thereof. The multifunction carbon rod filter cartridge is capable of effectively removing residual chlorine and heavy metal in tap water and has good effects of killing and restraining bacteria. The multifunction carbon rod filter cartridge comprises, by mass percentage, 50%-98% of activated carbon, 1%-30% of modified cellular material powder and 1%-20% of adhesive. The preparation method includes mixing the activated carbon, the modified cellular material powder and the adhesive, drying, pouring dried mixing materials into a charging port of a screw extruder, heating the screw extruder, extruding the hollow column-shaped formed carbon rod filter cartridge, and cutting the carbon rod filter cartridge according to required lengths.

Description

technical field [0001] The invention relates to a carbon rod filter element, in particular to a multifunctional carbon rod filter element and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, the demand for water resources is increasing rapidly. At the same time, due to the accelerated pace of industrialization and urbanization, the shortage of fresh water resources and the pollution of the water environment have become increasingly serious. At the same time, people have higher and higher requirements for the quality of life. How to obtain clean and safe drinking water has become a worldwide problem. important topic. [0003] The traditional tap water treatment technology still uses the process of the last century, generally through chemical treatment processes such as coagulation (coagulation aid), flocculation, disinfection, oxidation, pH adjustment, softening, and algae killing, to simply process river water o...
