Abstract

The invention provides a method for automatically detecting sulfide in waste water containing sulfide pollutants, wherein the method is accurate in result and free of environmental pollution. The method comprises a standard curve calculation step, a pretreatment step and a determination step. According to the method, the sulfurized pollutant S < 2-> in the wastewater can be detected in a standardized manner, and the accuracy can be improved under the condition that the consistency of detection results is ensured through multiple times of detection. Through accounting, compared with a single detection method in the prior art, the method can improve the accuracy by 30%, is especially suitable for different occasions, and enlarges the application range and scene of the S2-detection method.

Description

technical field [0001] The invention relates to the technical field of detecting impurities with polluting properties, and more particularly relates to a method for detecting sulfide pollutant wastewater. Background technique [0002] Water pollution is the reduction or loss of the use value of water caused by harmful chemicals, polluted water, acids, alkalis, oxidants in sewage, and compounds such as copper, cadmium, mercury, arsenic, benzene, dichloroethane, ethane Organic poisons such as glycols can poison aquatic organisms to death and affect drinking water sources and scenic spots. When organic matter in sewage is decomposed by microorganisms, it consumes oxygen in water and affects the life of aquatic organisms. Oxygen decomposes to produce unpleasant gases such as hydrogen sulfide and mercaptan, further deteriorating the water quality. [0003] Sulphides mainly exist in domestic sewage and fluid flows in some industrial occasions, and some special groundwater (such a...
