Abstract
본 발명은 난분해성 물질을 포함한 특정 염색폐수의 소각처리방법에 관한 것으로, 아주 간단히 염색폐수에 포함된 비닐계물질의 성분을 분리시켜 소각처리할 수 있도록 함으로써 하천이나 강에 염색폐수를 무단 방류시키지 않도록 하여 자연환경을 보호할 수 있도록 한 것이다.The present invention relates to a method of incineration of a specific dye wastewater containing hardly decomposable substances, which is very simple to separate the components of the vinyl-based material contained in the dye wastewater to be incinerated so that the dye wastewater is not discharged into the river or river. It is to protect the natural environment.
상기와 같은 목적달성을 하기 위한 염색 폐수처리방법은 염색폐수에 알코올 용매로 가하여 침전된 비닐계물질인 PVA 및 PVAc와 용액으로 분리시키고 상기 용액은 증류시켜 알코올과 잔여용액으로 분리시킨후 알코올을 회수하여 재사용하고 잔여용액은 다시 순간증류시켜 액성여액과 침천물로 분리시킨 다음 액성여액은 기존폐수처리장으로 보내고 상기 침천물과 기 침천된 비닐계물질을 소각처리하는 염색 폐수처리방법에 관한 것이다.Dyeing wastewater treatment method for achieving the above object is separated into a solution with PVA and PVAc, a precipitated vinyl-based substance by adding alcohol solvent to the dyeing wastewater, and the solution is distilled to separate the alcohol and the remaining solution to recover the alcohol The present invention relates to a dye wastewater treatment method in which the remaining solution is instantaneous distillation again to separate the liquid filtrate and the sediment, and the liquid filtrate is sent to an existing wastewater treatment plant.
