Hydrogen sulfide containing sewage treatment agent test device

Abstract

The invention relates to a hydrogen sulfide-containing sewage treatment agent test apparatus, and belongs to the technical fields of petroleum engineering oilfield chemical agent detection and evaluation. The apparatus comprises a sampling device and a detecting device, wherein the sampling device is composed of a sampling barrel, a handle, a piston and an absorption bottle, and the detecting device comprises a reaction kettle and a sealing cover. The apparatus can realize field sampling of hydrogen sulfide-containing sewage under closed conditions, field temperature and volume measurement, transfer of an indoor sewage sample, and hydrogen sulfide-containing sewage treatment agent test at a temperature consistent with the temperature of the sampling field, so hydrogen sulfide-containing wastewater composition change caused by the volatilization of the hydrogen sulfide gas dissolved the sewage or a reaction of the hydrogen sulfide gas and oxygen in the air is prevented, the health of sampling and detecting people is guaranteed, and the validity of the hydrogen sulfide-containing sewage treatment agent test is improved.

Description

Technical field [0001] The invention relates to a test device for a sewage treatment agent containing hydrogen sulfide, which belongs to the technical field of detection and evaluation of chemical agents in petroleum engineering oil fields. Background technique [0002] The industrial sewage produced in the production of high-sulfur gas fields contains a large amount of toxic and harmful gases, bacteria, mechanical impurities and other harmful components, especially a large amount of dissolved hydrogen sulfide gas, which has a greater impact on human health and the environment after volatilization. In order to prevent industrial pollution, the harmful components contained in the hydrogen sulfide sewage are treated and then reinjected into the stratum for sewage treatment and recycling. The injection of different types of sewage treatment agents is a widely used sewage treatment method. Therefore, the indoor test results of the sewage treatment agent directly affect the use of the...

Problems solved by technology

[0004] The purpose of the present invention is to make the existing hydrogen sulfide-containing sewage sampling, water sample transfer and sewage treatment agent detection process possible due to the poor airtightness of sewage sampling containers and reactors during the test of hydrogen sulfide-containing sewage treatment agents in the prior art. Hydrogen sulfide gas volatilizes or reacts with oxygen in the air, resulting in changes in the composition of the sewage water sample, which not only affects the validity of the test, but also makes the test results unable to reflect the field application effect of the hydrogen sulfide-containing sewage treatment agent, and the hydrogen sulfide gas In view of the volatile hazards of sampling and the health of inspection personnel, a test device for sewage treatment agents containing hydrogen sulfide is provided, which can sample hydrogen sulfide-containing sewage and measure temperature and volume under closed conditions on site, and indoor sewage water samples are sealed and pipetted and collected. Sewage treatment agent tests are carried out under the same temperature as the sampling site to prevent the hydrogen sulfide-containing sewage components from changing due to volatilization of dissolved hydrogen sulfide gas in sewage or mixing with oxygen in the air to ensure sampling and testing personnel Good health to improve the validity of the test of hydrogen sulfide-containing sewage treatment agent
