陶粒濾料是以精制陶土為主要原料，摻加適量改性劑，經粉碎、混練、成型和高溫煅燒而制成的，不含任何對人體和環境有害的物質。其表面堅硬、粗糙，內部疏松多孔，具有機械強度高、比表面積大，孔隙率大的特性。用于水處理中，具有表面性狀好、截污能力強、過濾水頭損失小，反沖洗耗水量低、化學穩定性和生物穩定好、使用壽命長的特點。陶粒濾料是種能增加水產量，提高出水質量，節省藥劑和能耗的新型高效過濾材料。

Ceramic grain filters are made of refined pottery clay s adder with certh certain modifiers,adn processed of grinding,mixing,shaping and high temperature sintering.They do not contain any substances that harmful to people or environment.They are the advantages of high mechanical strength,large specific surface area and porosity.When used in water treatment,they behave a activated surface property,a great amount of pollutant entrapment,less water head loss in the filter bed,lower consumption of back-flush water,stable in chemical and gbiologic property,and long service life,Ceramic grain filters is a new and efficient filter material to increace the water yield,upgrade the water quality,and save chemicals and energy.
