The invention discloses an environment-friendly
treatment system capable of realizing harmless treatment of
drilling waste. A first liquid-phase collecting tank is arranged below a
liquid waste outlet of a high-frequency
drying vibrating
sieve, a
solid waste outlet of the high-frequency
drying vibrating
sieve is connected with an inlet of a rock waste spin-
drying machine through a first screw conveyer, a second liquid-phase collecting tank is arranged below a
liquid waste outlet of the rock waste spin-drying
machine, and a
solid waste outlet of the rock waste spin-drying
machine is connected with a
solid waste transfer tank through a second screw conveyer; the first and second liquid-phase collecting tanks are connected with an inlet of a high-speed variable-frequency
centrifuge after being connected with a first
mud pump in series through pipelines respectively, a solid waste outlet of the high-speed variable-frequency
centrifuge is connected with the solid waste transfer tank through a third screw conveyer, and a third liquid-phase collecting tank is arranged below a
liquid waste outlet of the high-speed variable-frequency
centrifuge. With the adoption of the
system, treatment of waste while drilling can be realized, a
liquid phase can be recycled, solid waste is subjected to harmless treatment, potential
pollution risks are eliminated, the drilling cost is saved, and drilling operation requirements for having characteristics of flowability, temporality and
dispersity are met.
