Abstract

본 발명은 산업폐기물로 분류되어 톤 당 고가의 처리비용이 소요되는 제염공정 폐기물인 폐석고를 이용하여 산업 폐수 처리 방법에 관한 것으로써, 제염공정 폐기물인 기계염, 천일염 등의 제염공정에서 발생한 석고나 이를 탈 소금하거나 건조시킨 석고를 혼합하여 슬러리화한 석고와 이를 건조시킨 석고를 가성소다, 생석회, 소석회, 시멘트, 슬래그 등 알카리제를 단독이나 병행 사용하여 pH=10이상으로 유지한 산업 폐수에 (원 폐수의 pH가 11 이상일 경우는 가성소다, 생석회, 소석회, 시멘트, 슬래그 등 알칼리제를 사용하지 않을 수 있음) 주입하여(폐수 성상에 따라 응집효고를 높이기 위하여 폐수에 소다회, 탄산암모늄 등 카보네이트 화합물을 적당량 넣을 수 있음)이 용액을 수 분 동안 교반한 후 응집 침전 시키거나 침전 용액을 여과시켜 색도, 총 인, 총 질소, 탁도, 부유 고형물, 유기물 등을 저감하는 것을 특징으로 한다.The present invention relates to an industrial wastewater treatment method using waste gypsum, which is a decontamination process waste, which is classified as industrial waste and requires a high treatment cost per ton, and includes gypsum generated in a decontamination process such as decontamination waste, such as mechanical salt and sun salt. Gypsum obtained by mixing desalted or dried gypsum and dried gypsum is used in industrial wastewater maintained at pH = 10 using alkaline agents such as caustic soda, quicklime, slaked lime, cement and slag alone or in parallel. If the pH of the wastewater is 11 or higher, alkali agents such as caustic soda, quicklime, slaked lime, cement, and slag may not be used, and then injected (in order to increase the coagulation effect according to the wastewater properties) The solution is stirred for several minutes and then precipitated by coagulation or the precipitated solution is filtered It is characterized by reducing phosphorus, total nitrogen, turbidity, suspended solids and organic matter.
