Problems solved by technology
Once this phenomenon occurs, it is difficult to control, it usually takes a long time to adjust and recover, and because it occurs in lake sediments, it is usually difficult to detect
At present, there are few descriptions and studies on this phenomenon, and there is no technology and method to monitor the specific height of sediment expansion.

Abstract
The invention provides a biological sensor for monitoring the sediment expansion height and a monitoring method. The biological sensor comprises an aerating device, a signal acquisition device, multiple micro-biological fuel cells and a support. The support comprises a horizontal separation plate. The cathode of each fuel cell is arranged on the horizontal separation plate, and the anode is arranged under the horizontal separation plate. The cathodes and the anodes are fixed to the support. The anodes are connected to the cathodes through wires. Resistors are arranged on the wires. At least one of N cathodes is arranged in overlying water of the sediment and all anodes are sunk into the sediment. N cathodes are in different heights. The signal acquisition device is connected with the micro-biological fuel cells. The aerating device is arranged in the overlying water and provides oxygen for the cathodes of the micro-biological fuel cells. According to the invention, the system and the method are highly sensitive, simple in structure, and low in building operation and maintenance cost, and are the method and the technology for effectively monitoring the expansion height of the sediment.
Description
technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a biosensor for monitoring the expansion height of sediments and a method for using the same to monitor the expansion height of sediments. Background technique [0002] Sediment is one of the three major components of lakes (water, sediment and aquatic organisms), and is an important link and interface of the geochemical cycle of lake nutrients. Organic matter in sediments is an important nutrient source for aquatic organisms, and cannot be ignored in the calculation of regional carbon budgets. Its sources mainly include endogenous input and exogenous input. Among them, endogenous organic matter is mainly animals and plants produced by water body productivity itself. It is obtained from the deposition of residues, plankton and microorganisms, etc., and the external input is mainly the particulate and dissolved organic matter brought in during the rech...
