Abstract
The invention relates to an oilfield oily sewage treatment agent which mainly solves the problem that the oilfield oily wastewater treated by the existing treatment agent still has very high contents of COD (chemical oxygen demand) and heavy metals and can not satisfy the water quality discharge standard in the existing oilfield sewage treatment. The treatment agent is composed of the following components in percentage by weight: 0.5-1.0% of pH regulator, 0.7-1.0% of heavy metal remover, 1.0-1.5% of oxide remover, 0.5-1.0% of flocculant, 0.05-0.1% of coagulant aid, 0.2-0.5% of decolorant and 0.3-0.5% of hydrophobing agent. The water treated by the oilfield oily sewage treatment agent can satisfy the stratum reinjection and water quality comprehensive discharge standard, and is beneficial to environmental protection.
Description
Technical field
The present invention relates to a kind for the treatment of agent in disposing polluted water in oil technical field, especially a kind of oil-contaminated water of oil field treatment agent.
Background technology
Oil-containing wastewater composition is very complicated.Its waste water main source has some petroleum production wastewater such as well-drilling waste water, well-flushing waste water, acidizing and fracturing fluid waste water and Produced Liquid, its composition variation, containing a large amount of crude oil in water, also containing solubility salt and heavy metal, the natural impurity such as oil in water emulsion, solid particulate, hydrogen sulfide suspended, contains the acids on some additives being used for changing recovered water character and injection stratum, inhibiter, sticky steady agent, sterilant, scale inhibitor etc. in addition.COD, suspended substance, colourity, heavy metal equal size are high, and intractability is very large.Oil-containing wastewater COD after current existing treatment agent process, heavy metal content are still very high, only meet re-injection requirement, do not have process up to standard, do not reach the standard-required of water quality discharge, if outer row can serious environment pollution.
Summary of the invention
To the invention reside in the existing disposing polluted water in oil overcoming and exist in background technology after existing treatment agent process oil-containing wastewater COD, heavy metal content still very up to the problem required less than water quality emission standard, and a kind of oil-contaminated water of oil field treatment agent is provided.This oil-contaminated water of oil field treatment agent, after process, water quality can reinjection into reservoir up to standard and water quality comprehensive discharge standard, is conducive to environment protection.
The present invention solves its problem and reaches by following technical scheme: this oil-contaminated water of oil field treatment agent, its component and proportioning are as follows by weight percentage: pH value regulator 0.5--1.0%, removing heavy metals agent 0.7--1.0%, Deoxidating agent 1.0-1.5%, flocculation agent 0.5--1.0%, coagulant aids 0.05-0.1%, discoloring agent 0.2-0.5%, hydrophobizing agent 0.3-0.5%.
Wherein sodium hydroxide is used as pH value regulator; Removing heavy metals agent, for changing the existing forms of heavy metal ion in oilfield sewage, makes it change stable complex compound and compound state into from harmful ionic forms; Deoxidating agent, for cutting off the molecular chain of organic macromolecule compound, reduces its molecular weight, fundamentally reduces oilfield sewage chemical oxygen demand (COD); Flocculation agent can provide a large amount of complexing ions due to it, and can strong adsorption colloidal particle, by absorption, crane span structure, crosslinked action, thus makes coacervation of colloid; Coagulant aids utilizes its stronger adsorption, increases the density of throw out; Discoloring agent is for the treatment of the colourity of water quality; Hydrophobizing agent makes the flocs unit of coagulation surface have extremely strong
hydrophobic nature, is convenient to press filtration mud extraction.
The present invention can have following beneficial effect compared with above-mentioned background technology: this oil-contaminated water of oil field treatment agent, when medicament adds total dosage 3%, high for the COD of oilfield sewage, suspended substance, colourity, heavy metal equal size, by carrying out pH value adjustment, removing heavy metals to it, falling organism, decolorizing purification, flocculation sediment, hydrophobically modified, solid-liquid separation; By coordinating level Four fine filtering link after oil-contaminated water of oil field process, the centrifugation systems of high energy consumption can be replaced with the press filteration system of less energy-consumption, making water quality can the environment protection standard process of reuse up to standard or re-injection, greatly reduce processing cost.Fundamentally solve the risk of environmental pollution of oilfield sewage, result can meet GB8978-1996 " integrated wastewater discharge standard " requirement, meets the matter of fundamental importance policy of national environmental protection energy-saving and emission-reduction.
embodiment:
Below in conjunction with specific embodiment, the invention will be further described:
Embodiment 1
Weighing sodium hydroxide 0.5g, calcium oxide 0.49g, sodium bisulfite 0.21g, hydrogen peroxide 1.0g, Losantin 0.2g, Tai-Ace S 150 0.5g, anionic polyacrylamide 0.05g, nano titanium oxide 0.3g, in order above-mentioned medicament is added in 100g oilfield sewage respectively and stir, namely supernatant liquor fine filtering is obtained water quality up to standard.
Embodiment 2
Weighing sodium hydroxide 5Kg, calcium oxide 5Kg, sodium bisulfite 3Kg, hydrogen peroxide 12Kg, Losantin 2Kg, Tai-Ace S 150 6Kg, anionic polyacrylamide 0.5Kg, nano titanium oxide 3Kg, in order above-mentioned medicament is added in 1000Kg oilfield sewage respectively and stir, namely supernatant liquor fine filtering is obtained water quality up to standard.
Embodiment 3
Weighing sodium hydroxide 60Kg, calcium oxide 65Kg, sodium bisulfite 30Kg, hydrogen peroxide 130Kg, Losantin 25Kg, Tai-Ace S 150 70Kg, anionic polyacrylamide 5Kg, nano titanium oxide 35Kg, in order above-mentioned medicament is added in 10000Kg oilfield sewage respectively and stir, namely supernatant liquor fine filtering is obtained water quality up to standard.
In above-described embodiment 1-3, the water quality that oilfield sewage obtains after treatment, pH value adjusts to 7.5 by original 5.3, chemical oxygen demand COD Cr (mg/L) reduces to 109 by 1380, suspended substance reduces to 130 by 1960, petroleum-type reduces to 5.3 by 36, and sulfide reduces to 0.7 by 2.4, and total mercury reduces to 0.03 by 0.04, sexavalent chrome reduces to 0.23 by 0.37, arsenic reduces to 54 by 75, and chromium reduces to 55.9 by 130, and total cadmium reduces to 0.05 by 0.3, total lead reduces to 0.5 by 0.8, total copper reduces to 0.5 by 0.9, and total zinc reduces to 3.2 by 4.4, and total arsenic reduces to 0.2 by 0.5.As can be seen here, after the inventive method process water quality pollutant index all within National Pollutant control criterion.After the process of oil-contaminated water of oil field treatment agent, water quality can be used for oil field re-injection water, also can be used for afforesting depositing dust, oilfield sewage is converted into regenerated water source by original adverse condition, not only solves the potential pollution risk of oilfield sewage to environment, and achieves the resource utilization recycling of oilfield sewage.
