Water quality monitoring equipment and monitoring system based on micro-fluidic disc chip

Abstract

The invention provides water quality monitoring equipment and a monitoring system based on a micro-fluidic disc chip, the water quality monitoring equipment comprises a shell, the micro-fluidic disc chip and a digestion unit, a centrifugal center point is arranged in the micro-fluidic disc chip, and a digestion pool, a quantitative pool, a reaction pool, a B reagent preset pool and a C reagent preset pool are fixedly mounted in the micro-fluidic disc chip; and a liquid bag reagent TP-B and a liquid bag reagent TP-C. The water quality monitoring equipment and the monitoring system based on the micro-fluidic disc chip are reasonable in design, and can realize micro-fluidization of water quality detection, integrated automation of multi-step reaction, integration of high-temperature closed digestion and presetting and storage of reagents; therefore, the developed laboratory and the portable micro-volume low-power-consumption micro-fluidic chip water quality detection system have the outstanding advantages of small volume, extremely low reagent consumption and waste liquid consumption, extremely low power consumption, short reaction period and the like, and can lead the development direction of rapid standardization water quality instruments in the laboratory.

Description

technical field [0001] The invention belongs to the technical field of water quality monitoring equipment production, and in particular relates to a water quality monitoring equipment and a monitoring system based on a microfluidic disk chip. Background technique [0002] The common problems of existing laboratory water quality monitoring equipment are: the amount of samples and reagents is large (about tens of milliliters per index), most of the detection waste liquid is hazardous waste, the hidden danger of secondary pollution is large, and the time required for detection is long. There are many problems such as low degree of automation, cumbersome operation, and great influence from human factors of the operator. [0003] The common problems of existing online monitoring equipment are: large amount of samples and reagents (about ten milliliters per index, dozens of milliliters of pipeline cleaning waste liquid), serious secondary pollution, complex pump valve structure, p...
