In order to more clearly illustrate the specific embodiments of the present invention, the following examples are provided:
according to the monitoring method and the monitoring device for the sludge level increment of the bottom mud of the black and odorous water body, an electrochemical device is arranged for collecting environmental data according to the characteristics of accuracy and rapidity of electrochemical monitoring. The device mainly comprises an electrochemical device which is formed by a platinum-plated titanium alloy electrode of an anode electrode group and a silver/silver chloride electrode of a cathode electrode in a water body, and different potential differences of the anode electrode and the cathode electrode can indirectly reflect the environmental state around the anode electrode and the cathode electrode. The device is provided with a plurality of anode electrodes on an anode electrode group, a single cathode electrode is arranged on the top of the device, an internal circuit is formed by connecting each anode electrode with the cathode electrode through an electrode acquisition module in an electric control unit, and the cathode electrode of an external circuit is connected with the anode electrode through water or mud in the environment to form a loop at the other end of the device.
The working principle of the monitoring device is as follows: because the fixed difference existing in solid and liquid states in nature is inevitable, when solid bottom mud substances contact the platinum-titanium alloy plated anode electrode, the potential between the solid bottom mud substances and the silver/silver chloride cathode electrode is inevitably changed violently, and the change direction of the numerical value is negative. By utilizing the characteristic, the electric control unit detects the potential of each electrode twice within a certain time interval, and quickly detects two adjacent anode electrodes with the largest potential difference, and the elevation value of the anode electrode with a lower value is the position of the sediment surface layer. When the sediment level rises and the sediment contacts a new anode electrode, an electrochemical group with an originally negative ORP value still maintains the original state, but the ORP value of the electrochemical group consisting of the new anode electrode and a cathode electrode is rapidly reduced, and the difference between the ORP value and the ORP value of the electrochemical group of a higher order is maximum; when the sediment level is lowered, the ORP of the newly formed electrochemical set is changed rapidly, and the difference with the ORP value of the electrochemical set of the lower order becomes maximum.
The anode electrode group is arranged in a mode that an anode electrode interlayer plate 11 and a platinized titanium alloy electrode 12 are alternated, and the diameter of the electrode is smaller than that of the interlayer plate, and the diameter of the platinized titanium alloy electrode is the same, so that the shape changes the flow direction of the water body which is locally close to the device, the flow speed of the water body flowing on the surface of the anode electrode is increased, and the sedimentation of particles in the water body is effectively prevented.
The silver electrode in the cathode electrode is soaked in the silver chloride solution, the slow-release porous ceramic is arranged at the bottom, the connection between the solution in the electrode and an external water body can be ensured, the silver chloride solution in the cathode electrode forms slow-release electrons 14 in water, and the electrode failure caused by the rapid diffusion of the solution in the electrode cannot be caused. The structure can lead the solution released by the cathode electrode to carry electrons to be connected with the anode electrode through a circuit formed by an external environment, and the microprocessor 15 in the electric control unit is respectively connected with the cathode electrode and each layer of platinized titanium alloy electrode through a conducting wire, thereby being combined with an internal circuit to form a loop.
In addition, preferably, the electronic control unit is composed of a circuit system and a timing circuit in the prior art, and specifically includes:
1. GNSS positioning part: the positioning part is a GT-U12 dual-frequency GNSS positioning module, and different positioning systems can be selected according to the actual monitoring site requirement and the device compatibility consideration.

3. A gyroscope: the circuit board is coupled with the MEME micro-electromechanical gyroscope STLY 3200 ALH.
In addition, the present invention is preferably such that, in the detection process:
1. firstly, a battery is arranged in a monitoring device, the device is started, a top indicator lamp is observed to start to flicker very slowly, and the monitoring device starts to work at the moment;
2. and setting a program and selecting a proper monitoring time interval. The program starts the timing circuit, after a certain time interval, the processor sends out a monitoring command, quickly measures the oxidation-reduction potentials between all the positive electrodes and the negative electrodes, identifies the two positive electrodes with the largest potential difference, and records and outputs the electrode numbers (the system numbers all the electrodes from bottom to top, and the output numbers can be directly converted into elevation values).
3. The monitoring device is inserted into the sediment at the bottom of the water body, and at the moment, the monitoring device can be directly and manually inserted into the sediment of a place to be monitored, and other rods can be externally connected to the top of the monitoring device for depth operation. When the limit ring is in contact with the bottom mud obviously, the monitoring device is inserted downwards by a small distance forcibly, so that the bottom mud is in contact with the platinized titanium alloy electrode (in the device, the platinized titanium alloy electrode is an anode electrode, and the silver/silver chloride electrode is used as a cathode electrode), and the monitoring device is ensured to be vertical as far as possible in the process.
In addition, the invention is preferable, the small round hole on the limiting ring has two functions, firstly, the biochemical reaction of the local bottom sediment is not influenced as much as possible, and the influence of the monitoring device on the primary bottom sediment is reduced; secondly, when the monitoring device is inserted into bottom mud, the monitoring point position is soft due to local pressure, the bottom mud sinks, a small pit is formed in the point position, the bottom mud increment monitoring effect is influenced, unbalance of the local pressure can be greatly relieved due to the existence of the small circular hole, the bottom mud below the limiting ring can penetrate through the small hole to the upper side of the limiting ring, and the pressure pit is avoided.
In addition, the invention is preferable that a vibration dustproof function can be added on the detection rod, and a high-frequency direct-current vibration eccentric motor is fixedly installed in the detection rod.

The platinum or gold surface can be polished by toothpaste, then cleaned by pure water, and soaked in 3.5mol/L potassium chloride solution for 6 hours for reuse.
Finally, the experimental data for monitoring the sediment increment by adopting a potential monitoring means for water bodies in different areas are shown in the following table (unit mV):
the ORP of the bottom mud surface layer in the natural water body and the ORP of the water body have obvious rules from the table: the ORP of the bottom mud surface layer is always maintained between-450 and-350, and the ORP of the river water body is always maintained above 100. In extreme cases, the ORP value of the water body is lower than 0, but the difference between the ORP value and the ORP value of the bottom mud surface layer can be kept large. In the case of long-term stable monitoring, occasional phenomena of monitoring data fluctuations can be filtered using post-processing data. Therefore, the law that an obvious difference exists between the ORP of the bottom mud surface layer of the river channel and the ORP of the water body of the river channel can be effectively utilized on the monitoring device to monitor the liquid-solid interface of the bottom mud and the water body.
And fig. 7-9 show relevant data obtained by performing a bottom sludge ORP simulation experiment on the primary bottom sludge and the water body of the three rivers (a, b and c) under the pilot-scale test condition in a laboratory, wherein two ORP integrated electrodes are arranged in the experiment and are respectively positioned on the surface layer of the bottom sludge and at a position 50cm above the position, and ORP values are recorded at fixed time intervals. As can be seen from the figure, the bottom mud surface ORP of the three rivers of a, b and c and the water body ORP of the river keep large difference, and the fluctuation of the bottom mud surface ORP is small, so that the bottom mud increment data obtained by adopting a potential difference analysis method is more accurate and reliable compared with the bottom mud increment monitoring methods of ultrasonic waves and the like in the prior art.
Finally, the invention adopts the mature products and the mature technical means in the prior art.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
