s8, sensing the liquid level height in the first purified water storage cavity (23) by the liquid level meter (24), starting the first water pump (25) when the liquid level height in the first purified water storage cavity (23) reaches the set value of the control system, and extracting water through the purified water extraction pipe (26), wherein the first water separation branch is a first water separation branch;
s9, oil liquid extracted by an oil-water extraction pipeline (45) in the oil-water separation barrel (51) falls on an impurity separation filter screen (513), and the impurity separation filter screen (513) screens out impurities;
s10, more and more oil flows into the oil-water separation barrel (51) and reaches the position of the oil-water conveying pipe I (54), the water pump III (57) is started, and the oil on the upper layer of the oil-water separation barrel (51) is conveyed into the oil-water separation filter barrel (55);
s11, oil in the oil-water separation filter barrel (55) is separated through the filter (56), water enters the filter (56), and oil is left between the oil-water separation filter barrel (55) and the filter (56);
and S12, starting a water pump IV (59), and conveying the water in the filter (56) to a water purification storage barrel (510) through an oil-water conveying pipe II (58), wherein the water separation branch II is arranged, and oil-water separation is finished.
