A kind of curing agent for solid waste treatment and its application

Abstract

The invention provides a curing agent for solid waste treatment, which comprises the following components in parts by mass: 60-90 parts of high-calcium fly ash; 6-14 parts of desulfurized gypsum; 5-9 parts of volcanic ash; bentonite 1-5 parts; calcium chloride 1-5 parts; sodium sulfate 1-3 parts. The curing agent for solid waste treatment provided by the present invention has strong water absorption, and can achieve the effect of solidifying oilfield cuttings at low cost, convenience and high efficiency when applied in practice; it not only effectively utilizes solid waste as a resource, Moreover, it also solves the problem of difficult solid waste treatment in major enterprises; the curing agent of the present invention can realize rapid solidification of mud, and can reduce large-capacity mud storage pools; plant heavy metal-absorbing vegetation and complete vegetation growth experiments, especially can be used in Anti-drought, restoration of severe saline-alkali land, etc.; it not only protects the ecological balance, improves the living environment, but also plays an effective role in promoting the government to achieve sustainable development goals.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, in particular to water-based drilling waste cuttings. Background technique [0002] After the implementation of the new "Environmental Protection Law" in 2015, the treatment of drilling water-based solid-liquid waste has been put on the agenda. Oilfields have begun to test the technology of drilling water-based solid-liquid waste without landing. Government departments are also formulating relevant management measures to guide the drilling water Solid and liquid waste treatment reduction, emission reduction, harmless and resource utilization, to promote clean production in oilfields. Mud non-landing treatment and recycling technology collects waste drilling mud and cuttings while drilling on site, regenerates the separated waste mud, and reuses it for drilling to realize mud recycling. In the early stage, all drilling companies used traditional cement solidification method, the last thing pr...

AI Technical Summary

Problems solved by technology

[0004] In view of the high salinity of cuttings in the prior art, high COD value (chemical oxygen demand), low solidification rate, and long-term exposure of cuttings to pollute the environment, the plasticity of cuttings cured by existing cement is poor, and it is difficult to recycle The technical problem of secondary solidification, the present invention provides a curing agent for solid waste treatment and its use method. The separated rock debris and other wastes are added to the solid waste treatment developed in a targeted manner to realize on-site Harmless and resourceful, it has wide applicability in the field of petroleum solid waste treatment
