我国每年在工业生产中要更换下大量的废润滑油，这些油液绝大多数都被废弃。造成极大的浪费，并对环境造成极大污染。我校的废油再生技术填补了这项空白。为厂矿企业进行油液再生净化提供了理想手段，曾获煤炭部科技进步奖等多项奖励。 In our country, a large amount of waste lubricating oil needs to be replaced every year in industrial production. Most of these oils have been discarded. Causing great waste and causing great pollution to the environment. Our waste oil recycling technology fills this gap. For the factories and mines oil recovery and purification provided the ideal means to have won the Ministry of Science and Technology Progress Award and many other awards.
