A., as oil content < W, controller controls to open with the described electromagnetic valve stored on aqueduct that liquid case is communicated with, and the water storing liquid case is discharged in retaining well;
B. as oil content >=W, the electromagnetic valve that controller controls on water return pipeline is opened, and controller controls the water pump be located on water return pipeline and drives water to be back to first order oil water separator;
(7-4) generate electricity and discharge the water through oil removal treatment:
Level sensor in retaining well detects the water level in retaining well, and the turbine generator be located in retaining well utilizes floating of water and impact force generating, and electric energy is input in dynamical system;
As the water level >=H in retaining well, controller controls the electromagnetic valve be located on drainage pipe and opens, and the water through oil removal treatment is discharged from delivery port.
8. the control method of semi-submersible type sea oil spill cleaning ship according to claim 7, sewage quantity regulating box is provided with between described first order oil water separator and the delivery port of water inlet pipe, be provided with level sensor in sewage quantity regulating box, water inlet pipe front end is provided with electromagnetic flow control valve; Afterbody is stored 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:
Be provided with water level critical field in controller, as oil content >=W, the electromagnetic valve that controller controls on water return pipeline is opened, and controller controls the water pump be located on water return pipeline and 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 when the water level in sewage quantity regulating box is greater than the higher limit of water level critical field, controller controls by electromagnetic flow control valve the discharge of sewage entered in water inlet pipe to be reduced;
When the water level in sewage quantity regulating box is less than the lower limit of water level critical field, controller controls by electromagnetic flow control valve the discharge of sewage entered in water inlet pipe and increases.
9. the control method of the semi-submersible type sea oil spill cleaning ship according to claim 7 or 8, it is characterized in that, H is the 82%-93% of retaining well height.
