Embodiment Construction
[0054] First, harmless drilling cuttings and magma mixed waste are harmlessly treated to prepare harmless cuttings. This method is completed through the following steps:
[0055] 1. Separation
[0056] Add a well-compatible separating agent with a mass percentage of 0.17% to the drilling waste fluid, stir well, stir evenly, and seal it for 6-8 hours to demulsify, oil-water mixture, oil-water mixture, and make crude oil from the sludge The crude oil is recovered after freeing from the mixture to the surface. After the above treatment, the remaining substances are tested, and the crude oil content is reduced to 3%. The remaining substances are mainly composed of cuttings, mud sand, waste water and suspended organic matter;
[0057] 2. Degreasing and sedimentation
[0058] Add the compatible oxidation adsorbent with a mass percentage of 0.205% to the substance prepared in step 2 and stir evenly, and leave it for about 4 to 6 hours. The oil-dispelling and settling agent will quic...
