Abstract

본 발명은 교반기내의 폐수 중에 플라이 애쉬를 1,000∼3,000pm 주입하여 교반시켜서 균일하게 용해시키고 현탁된 폐수 중에 무기 응집제 및 고분자 응집제를 각각 10∼50ppm 및 0.1∼0.5ppm 비율로 주입하여 교반시켜 면상 침전물을 생성시켜서 폐수를 처리하는 것을 특징으로 하는 플라이 애쉬를 이용한 폐수처리방법에 관한 것이다.In the present invention, the fly ash is injected into the wastewater in the stirrer by stirring at 1,000 to 3,000 pm to uniformly dissolve it, and the inorganic flocculant and the polymer flocculant are injected into the suspended wastewater at 10 to 50 ppm and 0.1 to 0.5 ppm, respectively, to stir the planar precipitate. The present invention relates to a wastewater treatment method using a fly ash, characterized by generating and treating wastewater.

본 발명에 의한 플라이 애쉬를 이용한 폐수처리방법은 종래의 벤토나이트에 의한 응집처리와 비교하여 비용 절감을 도모할 수 있고, 산업 폐기물인 플라이 애쉬를 이용하므로 환경보호에 기여할 수 있는 점에서 획기적인 방법이라 할 수 있다.Wastewater treatment method using the fly ash according to the present invention can be reduced cost compared to the conventional flocculation treatment by bentonite, it is an innovative method in that it can contribute to environmental protection by using fly ash, which is an industrial waste Can be.
