Water quality test method, system and device

Abstract

The invention provides a water quality test method. The water quality test method comprises the following steps: filtering a to-be-tested water sample, and obtaining a filtered water sample; homogenizing the filtered water sample, and obtaining a uniform water sample; and performing the biological toxicity test for the uniform water sample, and obtaining a toxic value. According to the method provided by the invention, after the to-be-tested water sample is filtered, the to-be-tested water sample is homogenized, in the prior art, the suspended components in the water sample are centrifugally separated by adopting a centrifugal separation way to obtain the real water sample component, by virtue of the homogenizing method in the method of the invention, the suspended components in the watersample can be dissolved or more uniformly distributed in the water sample, the water sample is uniform, the authenticity of the water sample can be ensured, no interference substance is introduced, and the water quality can be detected under the situation that the original components of the water sample are ensured not to lose or deteriorate. The invention also provides a water quality test systemand device. The water quality test system and device also have the beneficial effects.

Description

Technical field [0001] The present invention relates to the technical field of water quality testing, in particular to a water quality testing method, system and equipment. Background technique [0002] With the increasing diversification of sewage and wastewater, the requirements for sewage and wastewater treatment are also increasing, such as the requirement to control toxic pollutants in sewage and wastewater. At present, the determination of the toxicity of sewage and wastewater mainly includes traditional physical and chemical methods and biological methods. Since sewage wastewater contains various impurities, various types, and turbid water samples, although traditional physical and chemical testing can quantitatively analyze the content of main components in pollutants, there are many test items, high costs, and difficulty in monitoring various toxicants. Comprehensively reflect the comprehensive impact of various pollutants in the water sample on the environment and othe...
