[0002] The principle of denitrification filter tank treating sewage is mainly that, under the condition of oxygen deficiency, by adding proper carbon source, promotes denitrification bacteria to form biological membrane on quartz sand, ceramic particle and other medium. These bacteria can convert nitrate or nitrite in water into nitrogen gas through biological reduction, thereby effectively removing nitrogen pollutants in water. Meanwhile, the particulate filter material in the filter tank also has the function of intercepting suspended solids, which can remove suspended solids in the influent during the filtration process.
