8. drilling well method for treatment of waste material according to claim 4, which is characterized in that be provided on the surge tank (13)
Two densimeters, second densimeter are used to detect the specific gravity of the fluid in surge tank (13), the fluid in surge tank (13)
Specific gravity between l.lg/L between 3g/L when, controller control the second sewage pump (14) starting；When in surge tank (13)
The specific gravity of fluid when being less than l.lg/L, the controller, which controls the 4th sewage pump (25), to be stopped to surge tank (13) transport Stream
Body, and control the second blender (15) and stop working.
9. drilling well method for treatment of waste material according to claim 4, which is characterized in that one in multiple solid controlling tanks is
First solid controlling tank (2), another is the second solid controlling tank (4), and the entrance of the first solid controlling tank (2) is connected with drilling machine (1), drilling machine (1)
The slurries of discharge are by the screening of the second vibrating screen (3) in the first solid controlling tank (2), and slurry after screening is through pipeline to the
Two solid controlling tanks (4)；Desander (5) in second solid controlling tank (4) eliminates the solid particle that partial size in slurry is greater than 120 mesh
Come, and these solid particles are delivered to surge tank (13)；Third densimeter, the third specific gravity are provided on the holding vessel
The specific gravity for detecting the fluid in holding vessel is counted, when the specific gravity of the fluid in holding vessel is less than 1.05g/L, the controller
The 5th sewage pump (24) is controlled to second solid controlling tank (4) trandfer fluid.
