Abstract

The invention discloses a device for on-line detection and automatic alarm of toxic substances and a detection method of the toxic substances. The device comprises a microorganism electrolytic cell system, a computer, a control system and an alarm, wherein the microorganism electrolytic cell system is used for sensing a current change caused by introduction of toxic substances; the computer and the control system are used for controlling the operation of the whole device, and are connected with the microorganism electrolytic cell system and the alarm respectively. The microorganism electrolytic cell system comprises a microorganism electrolytic cell and a liquid storage tank, and the microorganism electrolytic cell is connected with the liquid storage tank, a liquid delivery pump and a hydraulic cyclone through connecting pipes. The detection method comprises a step of comparing the amplitudes of electric signals generated by the microorganism electrolytic cell before and after the addition of a sample. The invention has the advantages of high sensitivity, short detection time, simplicity in operation and the like, and can detect on-line the toxic substances in water and then give an alarm automatically. The monitoring and early warning level is greatly improved. This achievement is out of reach for routine monitoring means, and thus the invention has great social benefit.

Description

technical field [0001] The invention relates to a method and a device for detecting toxic substances in water by using a biological method. Specifically, the present invention relates to an online automatic detection method and an automatic alarm device for toxic substances in water using microbial electrolytic cell technology. Background technique [0002] With the rapid development of industrial and agricultural production and the improvement of people's living standards, the types and amounts of artificially synthesized chemical substances have increased sharply, and a large amount of pesticides, chemical fertilizers, heavy metals, industrial wastewater, and domestic garbage have been discharged into the environment, causing serious pollution to the environment. Substances undergo complex physical, chemical and biological transformation processes in the environment, and new pollutants will be formed. Some pollutants may also enter the food chain and accumulate in organism...
