【摘要】 本文通过中和、混凝沉降法除氟过程,研究了彩色显像管工业废水除氟的适宜工艺条件。现场试验表明:应用泥回流处理技术,采用高效絮凝剂处理含氟废水,排放废水氟含量可稳定在4-6mg/L之间,低于排放标准（10mg/L）,同时废水处理的成本大大降低。更多还原

【Abstract】 This paper, with counteraction and flocculating and depositing reaction, studies the suit technical condition of decreasing the fluoride concentration of wastewater. Experiment shows that if we apply the sludge cycled technology with the high efficient flocculant to treat the wastewater, fluoride concentration will decrease to 4-6 mg/L, far below the discharge standard. The wastewater treatment cost is also reduced.更多还原
