Abstract

The invention discloses a filler. The filler comprises an organic matter, microorganism stimulin, zero-valent iron particles, a pH buffering agent and an adhesive. The invention further discloses a starting device of a microorganism sensor, which comprises a shell and the above-mentioned filler filled in the shell for promoting the microorganism growth. The invention further discloses a preparation method of the above starting device of the microorganism sensor, and a system composed of the starting device and a sensor. According to the starting device of the microorganism sensor provided by the invention, in addition to the organic matter for providing nutrients for microorganisms, the microorganism stimulin is also added to the filler to promote the reproduction and growth of the microorganisms in the sensor and to accelerate the microorganisms to cover and rectify the entire electrode; the zero-valent iron particles are used to react with the oxygen and oxidizing substances in the soil to reduce the redox potential of the sensor into the water and to facilitate the growth of the microorganisms; and the pH buffering agent is used for preventing death of microorganisms caused by large changes in the pH in the underground water of the soil.

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 ...
