Fish and photogenic bacterium-based comprehensive toxicity online analyzer

Abstract

The invention provides a fish and photogenic bacterium-based comprehensive toxicity online analyzer. The analyzer comprises a sampling unit, a bacterium storage chamber, a reaction chamber, a salt solution unit, a detection unit, a control unit and a fish pond, wherein the detection unit comprises a dual-optical-path detection module and a behavior monitor; fish behaviors are monitored by the dual-optical-path detection module and the behavior monitor by utilizing a method of luminescent bacteria. The biological toxicity of a water body is determined by combining two methods, so that a sensitive, simple and convenient method with high repeatability for testing biological toxicity of environmental pollutant is realized, and the pollution situation of a water environment can be better known.

Description

technical field [0001] The invention relates to the field of water body pollution monitoring, in particular to an automatic water body biotoxicity monitor suitable for drinking water sources, rivers, lakes, oceans, sewage treatment plants, waterworks, drinking water plants, food and beverage and other industries. Background technique [0002] In the past 30 to 40 years, the variety and amount of synthetic chemical substances have increased dramatically, and the pollution to the environment has become increasingly serious, which has attracted the attention of countries all over the world. As early as the early 1980s, developed countries formulated a series of standards and work guidelines for the biological toxicity effects of chemicals. method. [0003] At present, the determination of wastewater toxicity mainly includes physical and chemical methods and biological methods. Traditional chemical and physical analysis methods can quantitatively analyze the content of main co...

Problems solved by technology

[0004] In the prior art, only a single subject is usually used for biological toxicity monitoring, but since different subjects have different reactions to pollutants, for example, luminescent bacteria are more sensitive to heavy metals, while organic pollutants are less sensitive. Relatively insensitive; while fish are not sensitive to heavy metals, but are more sensitive to organic toxic pollutants and cyanide, it is impossible to fully understand the pollution of the water environment when using the response of a single aquatic organism to judge the pollution of the water body
