The invention discloses a CSTR-based three-dimensional electrode MEC-fluidized bed reactor for anaerobic fermentation of cow dung and application, and belongs to the technical field of microbial electrochemistry. The reactor comprises a reactor main body, a feed port, a discharge port, a gas outlet and a stirring device, an anode and a cathode are arranged in the reactor main body, a conductive three-dimensional particle electrode filler is filled between the anode and the cathode to form a three-dimensional electrode system, and the anode and the cathode are connected with an external power supply. The three-dimensional electrode system is constructed, so that the reaction specific surface area and the electron transfer efficiency are greatly increased, the stimulation effect of a low-voltage electric field is amplified to the whole reaction space, and the technical bottlenecks of low mass transfer efficiency, low methane yield, easiness in system instability and the like in the traditional cow dung anaerobic digestion are solved. Compared with the traditional anaerobic digestion and two-dimensional microbial electrolysis cell, the two-dimensional microbial electrolysis cell disclosed by the invention can obviously improve the methane yield and the system operation stability, and has an excellent engineering application prospect.

This utility model provides a filtration and evaporation device for producing calcium formate, relating to the field of calcium formate production. It includes a filter chamber, an evaporation chamber, a mounting base, and a support frame. The filter chamber is located above the evaporation chamber, with the mounting base between them. The support frame is located at the bottom of the evaporation chamber. A first motor chamber is located inside the filter chamber, with discharge ports on both sides. The filter chamber communicates with the evaporation chamber through these discharge ports. A lifting assembly is located above the first motor chamber, and a filter assembly is located above the lifting assembly. A rotating shaft is located inside the evaporation chamber, driven by a first motor inside the first motor chamber. This utility model uses the first motor to drive the rotating shaft, which in turn drives the upper and lower anti-sticking wall components to rotate, thus cleaning the inner wall of the evaporation chamber.

The invention relates to a self-adaptive quantum random number generation method based on real-time entropy estimation, and belongs to the technical field of quantum random number generation. According to an existing integrated quantum random number generator, due to the non-stationary characteristic of a physical entropy source, the entropy rate dynamically drifts, and after-processing parameters are fixed, randomness safety and generation efficiency are difficult to guarantee at the same time. According to the method, the state transition probability of the original random bit stream is counted in real time, the confidence interval correction is introduced to calculate the minimum entropy, the input bit width is dynamically adjusted accordingly, the Toeplitz matrix is reconstructed for random extraction, and self-adaptive adjustment of the compression ratio is achieved. According to the method, the compression ratio is increased to ensure the security of the output random number when the entropy source quality is reduced, and the compression ratio is reduced to improve the generation efficiency when the entropy source quality is improved, so that the dynamic balance between the randomness security and the generation efficiency is realized on the premise of keeping integration and low cost.
