BOD-Q water quality analyzer

Supported by the National Natural Science Foundation of China's "Major Scientific Instrument Development Project", this projectBODThe principle and method of detection have been innovated, and the microbial Coulomb method has been creatively proposed and developedBODThe water quality measuring instrument series has independent intellectual property rights. This instrument has the following outstanding features. Firstly, the principle is that the device breaks through traditional methodsBODBy detecting the limitations based on the principle of dissolved oxygen consumption, an efficient microbial electrochemical platform was constructed, which achieved the extraction of electronic flow signals for organic matter biochemical degradation and measured the electrical capacity of the external circuit. Through the development and design of microbial anode, cathode, and electrolyte systems, this was achievedBODFast and accurate measurement; Secondly, it has strong timeliness and combines traditional methodsBODDetection time from5Days shortened to0.5~5Hours, and can be quickly detected1to128One sample, significantly improving detection efficiency; Thirdly, the results are accurate with a high degree of precision95%The above.
