摘要
Today, due to industrial development, the discharge of wastewater containing many kinds of organic and chemical substances, water pollution is recognized as a serious social problem. Commonly used water treatment technologies to date include biological treatment techniques using microorganisms and physical and chemical treatment techniques such as filtration, flocculation, precipitation or adsorption. However, biological treatment technology has a disadvantage in that construction cost is high and it is difficult to remove hardly degradable contaminants. Physical and chemical treatment technology not only has high operating costs but also separates contaminants with a large amount of sludge. There is a problem of causing secondary pollution.;Unlike other water treatment methods, which are fundamentally problematic, the advanced water treatment system adopts a fluidized photocatalytic oxidation reactor and a biochip filter tank that do not generate sludge, a secondary pollutant, by directly decomposing pollutants in water. ). In particular, in order to solve the expensive photocatalyst separation and recovery process, which has been a problem in the oxidation reaction using the conventional powder type TiO 2 photocatalyst, the TiO 2 photocatalyst is combined with an inorganic binder in a carrier having a density of 1.0-2.0 g / cm 3. It is a photochemical reaction water treatment apparatus (3) designed to fluidize the coated carrier (33) and the coated carrier (33) into a fluid (35) and a fluid hydrodynamic flow in order to obtain the maximum reaction efficiency. In addition, the filter used in the filter tank is provided with a biochip filtration device 4 that can be used permanently by facilitating backwashing using a biochip having a specific gravity lower than water.
