Abstract
본 발명은 화학공업폐수의 생물학적 처리방법에 관한 것으로, 좀더 구체적으로 화학공업폐수를 활성오니를 이용하여 처리하는데 있어서, 상향류식 유동상 반응조에서 입상으로된 활성오니를 이용하여 무산소 조건에서 폐수를 처리하는 것을 특징으로 하는 화학공업폐수의 생물학적 처리방법에 관한 것이다.The present invention relates to a method for biological treatment of chemical industrial wastewater, and more specifically, to treating chemical industrial wastewater using activated sludge, treating wastewater under anoxic conditions using activated sludge granulated in an upflow fluidized bed reactor. It relates to a biological treatment method of chemical industrial wastewater.
본 발명의 폐수처리 방법은 유기 탄소화합물과 질소화합물의 고부하 운전이 가능하고, 제거효율도 고효율이며, 고농도 입상형 오니의 조건에서 운전이 가능하므로 절대 잉여 슬러지의 발생량이 감소하였으며, 무산소 조건에서 운전되므로 산소공급을 위한 동력이 필요없이 고농도 유기물 질소화합물을 함유한 화학공업폐수의 경제적인 생물학적 폐수처리법이다.The wastewater treatment method of the present invention is capable of high load operation of organic carbon compounds and nitrogen compounds, high efficiency of removal, and operation under conditions of high concentration granular sludge, thus reducing the amount of absolute excess sludge and operating in anoxic conditions. Therefore, it is an economical biological wastewater treatment method of chemical industrial wastewater containing high concentration of organic nitrogen compound without requiring power for oxygen supply.
