LCD (liquid crystal display) industrial wastewater advanced treatment technology

The invention discloses an LCD (liquid crystal display) industrial wastewater advanced treatment technology. The LCD (liquid crystal display) industrial wastewater advanced treatment technology mainly comprises the following steps: carrying out pretreatment on LCD industrial wastewater by adopting a traditional water treatment technique; then putting the LCD industrial wastewater into a hydrolysis acidification pool so as to improve the biodegradability of wastewater; then guiding supernate into an ozone high-level oxidation reactor after the treatment by a BNR (Biological nutrient removal) unit, and removing low-concentration degradation-resistant organics in wastewater; and then, enabling yielding water of the ozone high-level oxidation reactor to flow through a BAF (biological aerated filter), an efficient settling pond, a micro filter chamber and a disinfecting tank. Degradation-resistant pollutants in the LCD industrial wastewater are decomposed so as to achieve the aim of water purification. The technology disclosed by the invention not only can be used for reducing the treatment and investment costs and the occupied areas, but also can be used for treating pollutants which cannot be removed by a traditional technology and performing advanced treatment on the LCD industrial wastewater; the water quality indexes of yielding water after treatment meet the IV-type surface water quality requirement of surface water environmental quality standards GB3838-2002, thus realizing harmless treatment and recycling of the industrial wastewater.
