Abstract

The invention discloses a filler, which includes organic matter, microbial stimulant, zero-valent iron particles, pH buffering agent and adhesive. The invention also discloses a start-up device for the microbial sensor, which comprises a shell and the above-mentioned filler filled in the shell for promoting the growth of microorganisms. The invention also discloses a preparation method of the starting device of the microbial sensor and a system composed of the sensor. In the starting device of the microbial sensor provided by the present invention, in addition to adding organic matter for providing nutrients to the microorganisms, a microbial stimulant is added to the filler to promote the reproduction and growth of the microorganisms in the sensor, and accelerate the coverage of the microorganisms to rectify the entire electrode; zero price Iron particles, used to react with oxygen and oxidizing substances in the soil, reduce the redox potential of the sensor into the water, and facilitate the growth of microorganisms; pH buffers, used to prevent the death of microorganisms caused by large pH changes in soil and groundwater.

Description

technical field [0001] The invention relates to the field of microbial sensors, in particular to a filler, a starting device, a preparation method thereof, and a microbial sensor system, in particular to a filler, a starting device, a preparation method thereof, and a microbial sensor system for starting a microbial sensor of groundwater in soil . Background technique [0002] Microbial electrochemical sensors have been widely used in water quality early warning due to their small size, low cost, good selectivity, high sensitivity, and fast response. Microbial electrochemical sensors use living microbial materials as sensitive elements, electrodes as acquisition elements, and sensors that detect signals characterized by current or potential. They have the advantages of high selectivity, direct and rapid acquisition of complex system composition information, and wide applications. prospect. [0003] The first step in the use of microbial electrochemical sensors is to start ...
