Description
Technical field
The invention belongs to slag applied technical field more particularly to a kind of sides preparing greasy filth curing agent using steel slag particle
Method.
Background technology
Oil sludge and sand or oily sludge are that silt particle or other media are mixed into oil extraction, and oil therein cannot be returned directly
Receive and may cause the mixture of the variform of environmental pollution.Oil sludge and sand typically contains the substances such as benzene class, phenols and anthracene class, and
With stench and toxicity, belong to《National Hazard waste register》In the hazardous waste listed, the harmfulness of hazardous waste is mainly toxic
Evil property, corrosivity, inflammability, reactivity and infectiousness etc..Its particularity show for danger short-term acute risk and
In long-term potential danger.If directly being contacted with natural environment, larger pollution can be caused to soil, water body and air, while also anticipating
Taste the waste of petroleum resources.Therefore, either from environmental protection still from recycling the energy from the point of view of, all should be to greasy filth
Sand carries out innoxious, minimizing, recycling treatment.
The universal processing method of oil field mud and sand is outdoor simple stacking and landfill, the contamination control and money of oil sludge and sand at present
Sourceization utilizes, it has also become perplexs the problem of petroleum industry.What country newly revised for 2015《People's Republic of China's solid waste is dirty
Contaminate the anti-therapy of environment》, more strict requirements are proposed to the prevention of the hazardous solid wastes such as oil sludge and sand.
Since the grindability of slag is poor, hydration activity is low and stability is poor, thus the comprehensive utilization ratio of slag is relatively low.At present
The utilization rate of China's slag only has 10% or so, the solid waste low as utilization rate.The stacking of slag brings serious ring
Border problem.And tract is occupied, bring huge pressure for the sustainable development of social economy and ecological environment.
Compared with other materials, slag has higher intrinsic strength and larger inner ratio surface area, these are characterized as steel
The comprehensive utilization of slag provides certain convenience.
Invention content
Goal of the invention：The purpose of the present invention is to provide a kind of methods preparing greasy filth curing agent using steel slag particle, should
