Embodiment 1
[0047] see figure 1 , a kind of scatter coating type oily sediment processing method, comprises the following steps:
[0048] S1. Disperse and pulverize the oily sediment to be treated, then sieve and disperse evenly, and start oil absorption treatment;
[0049] S2. After sieving, the oily sediment is evenly sprinkled onto the pre-oil-absorbing coating ball 1 from top to bottom, and the pre-oil-absorbing coating ball 1 coats the oily sediment and spits out the treated sediment;
[0050] S3. The sediment slides down on the pre-oil-absorbing coated ball 1 and enters the cleaning pool, and the oil is forced to concentrate on the water surface by means of ultrasonic cleaning and steam stripping;
[0051] S4, using an oil-water separator to extract crude oil, and then using a cyclone separator to separate the sediment;
[0052] S5. After the crude oil adsorbed on the pre-oil-absorbing coated ball 1 is desorbed, the pre-oil-coated ball 1 can be put into use repeatedly.
