Problems solved by technology

[0004] Now for some water samples containing solid particles, due to the deposition of solid particles, it is easy to block the pipeline of the test equipment, resulting in inaccurate test results and frequent maintenance of the equipment; and the heating of the acid in the acidification process of the existing equipment is usually a water bath Heating, this kind of heating has a large hysteresis defect, and the heating temperature of the acid solution cannot be adjusted in time, thereby affecting the acidification process of the fluidized material, and also causing inaccurate final test results; and the general acid solution and water in the prior art The mixing, acidification, and blowing of the sample are all in one reactor, resulting in incomplete acidification and inaccurate test results; finally, the current testing equipment generally has a relatively simple structure and a low degree of automation, requiring the user to manually control the process of liquid sampling. Cause water sample detection test operation is inconvenient and labor-intensive

Description

technical field [0001] The invention relates to water quality sulfide detection equipment, in particular to a fully automatic water quality sulfide acidification gas blowing detection system. Background technique [0002] Sulphides in water include dissolved H 2 S, HS-, S 2 -, Soluble sulfides, acid-soluble metal sulfides and unionized organic and inorganic sulfides in suspension. Hydrogen sulfide easily escapes from water into the air, producing the smell of rotten eggs, and is very toxic. As long as the water contains hydrogen sulfide of a few tenths of a milligram per liter, it will cause discomfort; it can harm cytochrome and oxidase, and cause cell tissue Hypoxia, even life-threatening. Therefore, the control of sulfide indicators in water and soil is a very important part of environmental protection construction. [0003] The existing method is to detect the sulfide content of surface water, groundwater, domestic sewage, industrial wastewater, seawater and soil sam...
