Abstract
The present invention relates to a sewage treatment reagent, especially a bactericidal agent for treating sewage containing oil, it is 2, 2-dibromo-3-cyano propionamide alcohol solution, tetrakis (hydroxymethyl) phosphonium sulfate water solution, sodium dodecyl benzene sulfonate, and isothiazolone as raw materials according to a certain ratio of the weight to prepare. Using the said bactericidal agent of this invention, it is low dosage, good disinfecting effect, high removing rate and sterilizing long time.
Description
Technical field
The present invention relates to a kind of waste water treatment with medicament, particularly a kind of bactericidal agent that is used to handle oil-polluted water.
Background technology
Oil and natural gas accounts for very big proportion as one of important energy in world's Energy Mix, according to statistics, be 34.6% and 16.1%, 70 respectively in the sixties in 20th century, rise to 44.7% and 18.7% the eighties, and be 40% and 23% the nineties.Also rising significantly of yield along with oil and natural gas.Because petroleum exploration and development is movable and the increase of recovery activity, the raising of oil field composite water cut, the quantum of output of oil extraction-generated waste water constantly increases, requirement to waste water treatment is also improving constantly, the oil field waste complicated component, except containing solubility salt and heavy metal, the emulsified crude oil that suspends, solid particle, outside the impurity of day heat such as hydrogen sulphide, also contain some and be used for changing the chemical agent that aqueous nature, the condition of water quality complexity, the sulfate reducing bacteria that contains in the water, iron bacteria and saprophytic bacteria etc. grow in a large number, equipment and pipeline are caused great corrosion, the safe stable yields in oil field is caused very big harm.
At present, existing since handle the oilfield sewage sterilization treatment 1227, conventional dose such as glutaraldehyde exists dosage excessive, and the pesticide resistance of bacterium is also in continuous enhancing, is badly in need of wanting a kind of low dosage, long action time, bactericidal agent efficiently.
Summary of the invention
The object of the present invention is to provide a kind of bactericidal agent that is used to handle oil-polluted water, when handling oil-polluted water, consumption is few, and sterilization effect is good, sterilization clearance height, and the sterilization functions time is long.
The object of the present invention is achieved like this: a kind of bactericidal agent that is used to handle oil-polluted water, and it makes (consumption is a weight portion) by the following weight proportion raw material:
2.2-two bromo-3-cyano group propionamide content are 25% alcoholic solution 75-95, tetra methylol sulfuric acid phosphorus content is that 30% aqueous solution 1-10, active matter content are that 30% neopelex 1-5, active matter content are 14% isothiazolinone 1-10.
Prescription preferred weight (part) ratio range of preparation bactericidal agent of the present invention is:
2.2-two bromo-3-cyano group propionamide content are 25% alcoholic solution 80-90, tetra methylol sulfuric acid phosphorus content is that 30% aqueous solution 3-6, active matter content are that 30% neopelex 3-5, active matter content are 14% isothiazolinone 2-7.
Optimum weight (part) ratio range of the prescription of preparation bactericidal agent of the present invention is:
2.2-two bromo-3-cyano group propionamide content are 25% alcoholic solution 80-85, tetra methylol sulfuric acid phosphorus content is that 30% aqueous solution 5-6, active matter content are that 30% neopelex 4-5, active matter content are 14% isothiazolinone 3-5.
The production method that above-mentioned each component is made bactericidal agent of the present invention is:
1. add the tetra methylol sulfuric acid phosphorus aqueous solution and mix in 2.2-two bromo-3-cyano group propionamide alcoholic solutions, stirring is more than 1 hour and keep temperature range at 15 ℃-45 ℃; 2. join step after neopelex and isothiazolinone being mixed 1. in the gained solution, stir, promptly get the bactericidal agent that is used for handling oil field sewage.
Wherein: 2.2-two bromo-3-cyano group propionamide alcoholic solutions claim 2.2-two bromo-3-itrile group propionamide alcoholic solutions again.
2.2-two bromo-3-cyano group propionamide alcoholic solutions are meant 2.2-two bromo-3-cyano group propionamides alcohol content=25%, under stirring, add content extremely all dissolves gained greater than 99% 2.2-two bromo-3-cyano group propionamide solids solution in absolute ethyl alcohol;
The tetra methylol sulfuric acid phosphorus aqueous solution is meant the aqueous solution of tetra methylol sulfuric acid phosphorus content=30%.
Neopelex active matter=30%;
Isothiazolinone active matter content=14%.
The bactericidal agent that is used to handle oilfield sewage of the present invention in use, its dosage is generally 5-50mg/L, its using method is: this agent directly can be put in the oilfield sewage, also can will be added behind this agent thin up again, the ratio of dilution is determined according to on-site actual situations.
Because the present invention is combined with each other the ratio collocation of multiple preferred sterilising components with science, make between each sterilising components and can learn from other's strong points to offset one's weaknesses mutually, and generation synergy, the concrete mechanism of action of the present invention is earlier by sulfydryl in the oxidizing bacteria enzyme, suppress dehydrogenase activity and kill a large amount of bacterial classifications fast, again by the strong quaternary alkylphosphonium salt structure control of the strong antibacterial activity of stability with suppress regrowing of bacterium, play the effect of killing livestock by the key that disconnects bacterioprotein again, the microorganism of wherethrough reason just can not synzyme and secretion has adhering and the biomembranous material of production, destroy the growing environment of bacterium, thereby reinforcement sterilization effect, produce synergistic effect, add low dose of bactericidal agent of the present invention and just can reach very high sterilization effect.When handling oil-polluted water with bactericidal agent of the present invention, consumption is few, and sterilization effect is good, sterilization clearance height, and the sterilization functions time is long.
Carried out comparative trial with the bactericidal agent that is used to handle oilfield sewage of the present invention adopting southern multi-purpose station, the bactericidal agent of contrast is commercially available 12 alkane bases, two first base Benzyl ammonium chlorides, Babysafe, glutaraldehyde, and result of the test is as shown in table 1:
Each bactericidal agent is to the contrast experiment of disposing polluted water in oil
Table 1
From above-mentioned contrast and experiment as can be seen, the effect that adopts the bactericidal agent that is used to handle oilfield sewage of the present invention to handle oilfield sewage all is better than contrasting the treatment effect of bactericidal agent, and consumption is minimum, long action time.
Embodiment
Below will be by table 2 explanation 6 embodiment of the present invention, each embodiment takes by weighing raw material, unit by separately raw material proportioning respectively: kilogram.
Table 2
The production method of making bactericidal agent of the present invention by each component of the foregoing description is by following steps:
1. add the tetra methylol sulfuric acid phosphorus aqueous solution at 2.2-two bromo-3-cyano group propionamide alcoholic solutions and mix, stirring is more than 1 hour and keep temperature range at 15 ℃-45 ℃; 2. join step after neopelex and isothiazolinone being mixed 1. in the gained solution, stir, promptly get the bactericidal agent that is used for handling oil field sewage.
