- Abstract:
- The high fluorine and high hardness influent of a wastewater treatment plant in a liquid crystal panel factory includes fluorine containing wastewater and organic wastewater. The fluorine containing wastewater is pretreated by coagulation, precipitation and MBBR nitration to reduce the hardness, F- concentration and ammonia nitrogen, and then mixed with the organic wastewater. The mixed wastewater is eventually treated by a combined process consisting of biochemical treatment, ozone advanced oxidation, biological aerated filter, high efficiency precipitation and disinfection. The final effluent quality stably reaches the requirements of surface water class Ⅳ limitations. The capacity of this plant is 6×104 m3/d, the investment is approximately 5 935 yuan/m3, and the footprint area is 0.619 m2/（m3·d-1).
