化学实验过程中经常会产生某些有毒气体、液体或固体,需要及时处理,特别是某些剧毒物质,如果直接排出可能污染周围环境,损害人类健康。因此,对废气、废液和废渣要经过一定的处理后才能排弃。不同的废水、废气,其污染物组成不同,处理方法也不尽相同。一、废液、废气的处理原则1.实验室污水、废气要分类收集,就地、及时处理,操作要求简单,成本 Chemical experiments often produce certain toxic gases, liquids or solids, the need for timely treatment, especially some highly toxic substances, if the direct discharge may pollute the surrounding environment, human health damage. Therefore, the exhaust gas, waste and waste to go through certain treatment before abandonment. Different waste water, exhaust gas, the composition of its different pollutants, treatment methods are not the same. First, the waste water, waste gas treatment principles 1. Laboratory sewage, waste gas to be classified collection, on-site, timely processing, operation requires a simple, cost
