불소이온 및 시안이온을 함유한 PH 7의 코우크스가스폐수를 상온에서 먼저 소석회를 투입시켜 PH를 7.5-11로 조절하여 1차 반응시킨후, 황산알루미늄을 첨가하여 PH를 6.0-8.0으로 조절하여 2차 반응시킨 다음, PAA(Poly Acryl Amide)2-6ppm을 첨가하여 플록을 향상시켜 불소이온 및 시안이온을 첨가시킨후 분리 제거하는 것을 특징으로 하는 코우크스 가스폐액에서 발생되는 불소이온 및 시안이온 동시처리 방법.The coke gas wastewater containing PH 7 containing fluorine and cyan ion was first reacted with lime in a room temperature at first, and the pH was adjusted to 7.5-11. Then, the pH was adjusted to 6.0-8.0 by adding aluminum sulfate. After the second reaction, 2-6 ppm of poly acryl amide (PAA) is added to enhance floc, and fluorine and cyan ions generated from the coke gas waste, which are separated and added after addition of fluorine and cyan ions.
