Example Embodiment
[0024] Example 1, referring to Figure 1, after recovering the drilling waste from the oilfield waste, it first enters the cleaning separation system, and after mixing with water in the cleaning separation system at a volume ratio of 1:3, adding a separating agent of 20% of the mixture volume, After circulating and stirring in the tank, the solid phase sieved through the vibrating screen is conveyed to the mixing and solidification system by the screw conveyor at the bottom of the vibrating screen. The solid phase is in the mixing and solidification system with a weight ratio of 2:1:1. Powder, lime, and ferrous sulfate are mixed, and a solid phase material with a certain strength is output from the lower belt conveyor. It can be used as a raw material for building materials. The solid phase is mixed and solidified. After testing, various indicators meet the national emission standards; vibrating screen screening After the liquid phase enters the lower buffer tank, it is pumped to...
