Abstract

본 발명은 참나무, 소나무, 오리나무, 미류나무, 아카시아나무 및 낙엽송으로부터 이루어진 것에서 것에서 선택된 나무의 톱밥으로 된 관에 중금속을 함유한 폐수를 알칼리성으로 조정한 후 통과시켜 중금속 함유 폐수를 효과적으로 처리하는 방법을 개시하며, 또한 크롬이온이 함유된 폐수의 경우 폐수를 1차적으로 산성으로 조절한 후 톱밥관을 통과시킨 다음, 2차적으로 폐수를 알칼리성으로 조정하여 톱밥관을 통과시킴으로서 효과적으로 처리하는 방법을 개시한다.The present invention is a method of effectively treating heavy metal-containing wastewater by adjusting the alkali-containing wastewater after passing alkali in a tube made of oak, pine, alder, rapeseed, acacia, and larch from the sawdust of the tree. In addition, in the case of wastewater containing chromium ions, the wastewater is first adjusted to acidic acid and then passed through a sawdust tube, and then the wastewater is adjusted to alkalinity and then a method of effectively treating the wastewater is passed through the sawdust tube. do.
