乳化液是金属加工时广泛而大量使用的一种冷却、润滑,防锈液、它的配方成分有多种,但多含有部分的油类。长期以来,很多工厂对使用后已腐臭的乳化液,都是直接倒入阴沟废掉。虽然很多工厂排放的乳化液量不大,但众多单位合起来, 其数量却相当惊人。它不仅造成污染,影响自来水的水质,也危害人民的健康,同时还浪费了宝贵的机油,真可谓“害民伤财”。 Emulsion is a widely used in metal processing and extensive use of a cooling, lubricating, anti-rust liquid, which has a variety of formulations, but contains more than part of the oil. For a long time, many factories have been used after the rancid emulsion, are directly into the gutter waste. Although the amount of emulsion discharged by many factories is small, the number of units combined is quite alarming. It not only causes pollution, affects the water quality of tap water, but also endangers the health of the people. At the same time, it has also wrecked precious oil, which is really “harmed people and money”.
