Abstract
An agent for treating oily sludge can be applied to oil sludge treatment in the petroleum industry. The weight percentages of components are as follows: 67-72% of CDKT-004 organic compound fertilizer, 7.5-8.0% of monopotassium phosphate, 11.25-11.5% of green gram starch, 3.25-3.5% of potassium sulfate, 1.5-1.75% of urea, 0.45-0.50% of iturin A, 0.15-0.16% of vitamin A, and light calcium carbonatein balancing amount; and the sum of all the weight percentages is 100%. The effects are as follows: the concentration of crude oil in soil is reduced to below 10 g/kg from 100 g/kg. The treated oily sludge can be used for planting crops and flowers, the environment pollution is reduced, and the environment-acceptable state can be achieved.
Description
Technical field
The present invention relates to the petroleum industry environmental protection technical field, relate in particular to a kind of medicament and treatment process of handling oily sludge.
Background technology
At present, the greasy filth, the oil-sand that produce in links such as crude production, processing, well workovers in the oil production process have characteristics such as generation is big, oleaginousness is high, heavy oil content height, the comprehensive utilization mode is few, intractability is big.Oily sludge is one of important pollutent that produces in oil-field development, the accumulating refining process; it also is a great problem that influences oil field and surrounding enviroment quality; listed in " Hazardous wastes " register by State Bueau of Environmental Protection, how to dispose oily sludge is the focus of paying close attention to always.Contain a large amount of aging crude oil, wax, bituminous matter, colloid, suspended solid, bacterium, sour gas, corrosion product in the oily sludge, comprise water conditioners such as hydrogen adds in the production process a large amount of flocculation agents, inhibiter, Scale inhibitors, sterilant; Also comprise heavy metals such as a large amount of pathogenic bacterias, parasite, Cu, Zn, Cr, Pb simultaneously, the hazardous and noxious substances of difficult degradations such as salt and polychlorobiphenyl, Dioxins, radioelement.Commonly used both at home and abroad: methods such as burning method, biological treatment, hot washing method, solvent extration, chemical demulsification method, solid-liquid isolation method, pyrogenic process, oily sludge profile control are handled oily sludge, but wherein all there are some problems in many methods, and practical application is not suitable for very much.Since the eighties in 20th century, bioremediation more and more is subjected to people's attention, but long processing period, and is relatively poor to naphthenic hydrocarbon, aromatic hydrocarbons, heterocyclic treatment effect, adapts to high oily sludge is difficult.
Summary of the invention
The objective of the invention is: the treatment process that a kind of oily sludge is provided, in oily sludge, add and handle medicament, utilize the molecule infiltration principle, destroy oily sludge and contain the big-and-middle hydrogen bond of heteroatoms molecule and cause colloid and bitum aggregation structure, with nearly 85% former oil decomposition in the soil; Contaminated soil reaches environmentally acceptable condition.
The technical solution used in the present invention is:
One, the raw material of processing oily sludge medicament comprises:
1, CDKT-004 compoiste fertilizer (industrial goods);
The CDKT-004 compoiste fertilizer has narration in " oil drilling technology " magazine the 5th phase in 2011 81 pages of scientific and technical information of upward being submitted the article by the stone skill in " introducing compoiste fertilizer in the Gemini quaternary ammonium salt class tensio-active agent and improve step-down augmented injection effect ".The character of CDKT-004 compoiste fertilizer: a kind of agricultural thing bio-organic fertilizer has good improving effect to the soil that hardens.Purposes: the organic fertilizer of grain and flowers.Production unit: the triumphant safe new technology in Chengdu limited liability company.
2, light calcium carbonate, specification: micro mist calcium carbonate (1～5 μ m) (industrial goods); The character of light calcium carbonate: the shape of light calcium carbonate is according to the difference of calcium carbonate grain shape, light calcium carbonate can be divided into fusiform, cube, aciculiform, chain, sphere, sheet shape and quadrangular prism shape calcium carbonate, the calcium carbonate of these different crystal forms can be made by the control reaction conditions.Light calcium carbonate is divided into by its original median size: particulate calcium carbonate (5 μ m), micro mist calcium carbonate (1～5 μ m), fine calcium carbonate (0.1～1 μ m), calcium carbonate superfine powder (0.02～0.1 μ m), super fine calcium carbonate (0.02 μ m).Purposes: can be used for following industry: rubber industry, paint industry, water-borne coatings industry, paper industry, cable industry, toothpaste filler.Manufacturer: Jingxing County principal column Condar lagging material factory.
3, Powder Phaseoli radiati (self-control), the mung bean of buying on the market is crossed the Powder Phaseoli radiati that obtains through grinding with 100 mesh sieves.
4, potassium primary phosphate (industrial goods)
5, vitriolate of tartar (industrial goods)
6, urea (industrial goods)
7, " the lipopeptid type biological surfactant progress " that iraq subtilis actinomycin A (Iturins) (industrial goods), Yang Futing are write is published in 124 pages of " fine chemistry industry " the 2nd phases in 2006.The character of iraq subtilis actinomycin A: can suppress the part bacterium, but but show strong inhibition fungi effect, test shows that it can suppress most fungi and yeast.After this there are a lot of scientists in Bacillus subtilis, to isolate antimicrobial substance, as mycosubtilin, bacillomycin L, bacillomycin D, and bacillomycin F, and their structure is illustrated.These compounds have identical constitutional features and biochemical characteristic, b referred to as " iturin lipopeptid family ", are commonly referred to as to be ' Iturins '.There is a beta-amino lipid acid (C among the iturin
14-C
17), 7 a-amino acid residues and 1 beta-amino lipid acid are linked to be a ring, and the chirality of this cyclic peptide is LDDLLDL in proper order, and wherein the configuration of these two amino-acid residues of D-Tyr2 and D-Asn3 is indeclinable.Purposes: iraq subtilis actinomycin A is one of bio-surfactant of foremost antimicrobial acivity the earliest.Compare with tensio-active agent, MICROBIAL SURFACTANT has the reduction surface tension, stable emulsion and increasing outside the effect such as foam, also possess not available nontoxic, the biological degradability of some tensio-active agents and stronger surface and interface activity, to the stability of heat, to ionic strength stability, breakdown of emulsion, under extreme pH also advantage such as effective.These characteristics of MICROBIAL SURFACTANT are particularly useful for petroleum industry and environmental engineering.As the degraded of oil, the recovery ratio that improves crude oil, the biological restoration of heavy oil contaminated soil etc.MICROBIAL SURFACTANT is as natural additive in addition, foodstuffs industry, fine chemistry industry, makeup, weaving production, stain remover and agriculture aspect all be widely used.Manufacturer: Beijing Jie Bote energy technology company limited
