Embodiment 1

[0028] Step 1. Weigh 100.00g of oily solid waste sample in a glass dish, place it in an oven, and dry it at 105°C until it reaches a constant weight. The weight of the sample after drying is 80.00g. This step takes 20-25 minutes;

[0029] Step 2, weigh 1.00g of the dried oily solid waste sample in a beaker, and add 70ml of spectral grade tetrachlorethylene solution into the beaker, and this step takes 5 to 8 minutes;

[0030] Step 3, add a magnetic stirring bar to the above beaker, place the beaker on the magnetic stirrer, adjust the magnetic field to control the stirring rate to 500rpm and stir for 5min;

[0031] Step 4, use a 0.45 micron organic microporous filter membrane to filter the mixed solution, and rinse the filter bottle with 10ml of spectral-grade perchlorethylene solution each time, for a total of three times, and this step takes 8 to 10 minutes;

[0032] Step five, take 15ml of the filtered extract in a cuvette, and use infrared spectroscopy at 3400cm -1 ~2400cm...

Embodiment 2

[0037] Experimenters have done five groups of tests according to the present invention, and the test data are as follows:

[0038] Comparison test:

[0039] serial number Standard sample oil content The present invention tests oil content time cost 1 5.00％ 4.94％ 49min 2 5.00％ 4.96％ 52min 3 5.00％ 4.93％ 50min 4 10.00％ 9.95％ 51min 5 10.00％ 9.93％ 53min

[0040] This test shows that the present invention can quickly measure the oil content of oily waste and solid waste, and the accuracy of the test results meets the requirements, and can be used for the determination of oily waste and solid waste in actual production.

[0041] The invention discloses a method for quickly measuring oil content, which comprises the following steps: weighing a certain amount of oil sludge and putting it into a drying box, completing the determination of water content and drying of water at the same time, weighing the quantitatively dried sampl...

Abstract

The invention relates to a method for rapidly measuring the oil content of oil stain solid waste. The method is characterized by comprising the following steps of: 1, weighing a group of test samples with the weighing precision of 0.01 g to obtain mass m1, putting the samples into a drying oven, and drying at 105 DEG C until the weight is constant to obtain mass m2; and step 2, weighing the dried sample with the mass of m3, putting the sample into a beaker, wherein each sample is 1-5g, then adding 20-100ml of spectrum grade tetrachloroethylene or carbon tetrachloride organic solvent into the beaker, and recording the use volume as V1. The method is simple and quick, can quickly measure the oil content of the oil stain solid waste, and solves the problem that the oil content of the oil stain solid waste cannot be quickly measured in production, which puzzles the production process for a long time.

Description

technical field [0001] The invention relates to a method for quickly measuring the oil content of oil pollution and solid waste, and relates to the technical field of sludge oil content detection. [0002] technical background [0003] The existing oil content test method is derived from CJ / T 221-2005, which is mainly for professional laboratories and has the characteristics of high detection accuracy, but the detection process is complicated and requires professional analytical chemists to perform acidification, evaporation and reflux, Washing, adsorption and other steps, according to the standard operating time of not less than 6 hours. [0004] In the oily sludge treatment project, the oil content is regarded as the core indicator of evaluation and treatment, and is under the supervision of the Environmental Protection Bureau and the oil field. Therefore, there is an urgent need for a convenient, fast and accurate oil content test method in the project, which can be used t...
