As the water level >=H in retaining well, the electromagnetic valve that controller control is located on drainage pipe is opened, and discharges from delivery port through the water of oil removal treatment.
8. the control method of semi-submersible type sea oil spill cleaning ship according to claim 7, between described first order oil water separator and the delivery port of water inlet pipe, be provided with sewage quantity regulating box, in sewage quantity regulating box, be provided with level sensor, water inlet pipe front end is provided with electromagnetic flow control valve; Afterbody holds liquid case and is connected with sewage quantity regulating box by water return pipeline; Electromagnetic flow control valve and level sensor are all electrically connected with controller; It is characterized in that, described step b is replaced by following step:
In controller, be provided with water level critical field, in the time of oil content >=W, the electromagnetic valve on controller control water return pipeline is opened, and the water pump that controller control is located on water return pipeline drives water to be back to sewage quantity regulating box;
Level sensor in sewage quantity regulating box detects the water level in sewage quantity regulating box, and in the time that the water level in sewage quantity regulating box is greater than the higher limit of water level critical field, the discharge of sewage that controller enters in water inlet pipe by electromagnetic flow control valve control reduces;
In the time that the water level in sewage quantity regulating box is less than the lower limit of water level critical field, the discharge of sewage that controller enters in water inlet pipe by electromagnetic flow control valve control increases.
9. according to the control method of the semi-submersible type sea oil spill cleaning ship described in claim 7 or 8, it is characterized in that, H is the 82%-93% of retaining well height.
