In the oil storage tank (103) with activated clay in the inner cavity, the waste oil that discharges water is decolorized by the activated clay to obtain recovered oil; 步骤六：将回收油在85-100℃条件下搅拌30-40min，之后加入氢氧化钠和碳酸钠继续搅拌1-3h，之后升温至115-136℃后加入脂肪醇类乳化剂继续搅拌1-2h，之后加入甲醇继续搅拌1-2h，得到该可生物降解的润滑油。Step 6: Stir the recovered oil at 85-100°C for 30-40min, then add sodium hydroxide and sodium carbonate to continue stirring for 1-3h, then heat up to 115-136°C, add fatty alcohol emulsifier and continue stirring for 1- After 2 hours, methanol was added to continue stirring for 1-2 hours to obtain the biodegradable lubricating oil.
