Curing agent for solid waste treatment and application thereof

Abstract

The invention provides a curing agent for solid waste treatment. The curing agent 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, 1-5 parts of bentonite, 1-5 parts of calcium chloride and 1-3 parts of sodium sulfate. The curing agent for solid waste treatment provided by the invention has strongwater absorptivity, and can be applied to practice to achieve the effect of curing oil field rock debris conveniently and efficiently at low cost. Not only the solid waste is effectively recycled, but also the problem that the solid waste of each large enterprise is difficult to treat is solved. The curing agent provided by the invention can realize rapid curing of slurry, and can reduce a large-capacity slurry storage pool. Heavy metal absorbing vegetation is planted and absorbed, a vegetation growth experiment is completed, and the method can be particularly applied to the aspects of drought resistance, severe saline-alkali soil remediation and the like. The ecological balance is protected, the human settlement environment is improved, and an effective promotion effect is achieved for the government to achieve the sustainable development goal.

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...

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 solidifi
