Problems solved by technology

[0003] Oily sludge is mainly oil sludge and oil sands produced in the production process of petroleum exploration and development industry and petrochemical industry. Oily sludge has a large amount of production, high oil content, high heavy components, few comprehensive utilization methods, and difficult treatment. Features, the existence of oily sludge has a negative impact on the quality of the surrounding environment, which is a relatively big problem in the treatment of solid waste at present. Chemical agents are the most common supplies for oily sludge treatment, but the existing chemical agents are expensive and difficult to treat. The effect does not meet people's expectations, which brings inconvenience to people's use

Abstract

The invention discloses an agent for treatment of oily sludge. The agent is composed of the following raw materials by weight: 4-8 parts of coconut shell powder, 5-12 parts of straw, 10-16 parts of diatomite, 2-5 parts of mint, 1.5-3 parts of angelica dahurica, 2-7 parts of licorice, 4-8 parts of bean dregs, 12-20 parts of flyash, 2-5 parts of honeysuckle, 1-3 parts of prunella vulgaris, 0.4-3 parts of sweet wormwood, and 0.5-2 parts of sodium hypochlorite. The invention also discloses a preparation method and a use method of the agent. The agent provided by the invention has the advantages of wide raw material sources, simple preparation process, and low production cost, and is suitable for large-scale industrialized production. The raw materials involved in the invention complement each other, lowers the concentration of crude oil in oily sludge, meet the national requirements, and can be recycled, thus achieving good economic and social benefits.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a medicament for treating oily sludge. Background technique [0002] Petroleum is a viscous, dark brown liquid. There are oil reserves in some areas of the upper crust, and the main components are mixtures of various alkanes, cycloalkanes, and aromatic hydrocarbons. The world's ocean area is 360 million square kilometers, about 2.4 times that of land. The continental shelf and continental slope are about 55 million square kilometers, which is equivalent to the sum of the area of ​​onshore sedimentary basins. 1 / 4 of the proven oil resources on the earth and 45% of the ultimately recoverable reserves are buried in the seabed. The center of gravity of the world's proven oil reserves will gradually shift from land to sea. Petroleum brings convenience to our life and production, but many pollutants are produced during the exploitation and processing of petroleum, and oily sludge is...
