Automatic monitoring equipment and method for multi-species water quality biotoxicity

Abstract

The invention discloses automatic monitoring equipment for multi-strain water biotoxicity. The automatic monitoring equipment comprises a PCL unit, a man-machine interaction unit, a flow path control unit, an anabiosis preservation unit, a sampling quantifying unit and a reaction detection unit, wherein the PCL unit, the man-machine interaction unit, the flow path control unit, the anabiosis preservation unit, the sampling quantifying unit and the reaction detection unit are all arranged inside a frame; the PCL unit is connected with the man-machine interaction unit, the flow path control unit and the reaction detection unit; the flow path control unit is connected with the anabiosis preservation unit, the sampling quantifying unit and the reaction detection unit. The invention further discloses a monitoring method for the multi-strain water biotoxicity. The automatic monitoring equipment has the advantages of multi-strain applicability, whole-journey detection, high measurement precision, short measurement time, small bacterial liquid amount, no cross interference, small maintenance amount and the like, and requirements of on-line environment monitoring can be met.

Description

technical field [0001] The invention relates to water quality monitoring in the field of environmental monitoring, in particular to an automatic monitoring device for multi-species water quality biological toxicity. Background technique [0002] With the rapid development of my country's social economy, environmental pollution is also becoming more and more serious. Various pollutants are directly discharged into rivers and lakes and other environmental water bodies, exceeding the self-purification capacity of water bodies, and water pollution continues to intensify. The traditional water quality monitoring method is a physical and chemical method, which can accurately determine the type and concentration of pollutants, but it takes a lot of time and energy to measure a large number of pollutants one by one, and it is impossible to measure the comprehensive effect of the interaction of multiple pollutants. [0003] Biological detection methods can make up for the shortcoming...

Problems solved by technology

However, there are still some problems in the application of this type of instrument, such as only a single bacterial species can be used, and it cannot be adapted to the measurement of fresh water and seawater at the same time; the fluorescence intensity is only measured at the end of the bacterial liquid reaction, and the fluorescence intensity change during the reaction process cannot be monitored; There are problems such as low degree of automation, high failure rate, long measurement time, poor repeatability, cross interference, high operating costs, and large amount of manual maintenance.
