Description

technical field [0001] The invention belongs to the technical field of microorganism identification, and in particular relates to an activated sludge microbial intelligent identification device and a method thereof. Background technique [0002] Common indicators of sludge activity include mixed liquid sludge concentration (MLSS), specific oxygen consumption rate (SOUR) and sludge settling ratio (SV), total weight of activated sludge solids (MLSS) and organic solids in activated sludge. The ratio of the total weight of substances can represent the relative value of activated sludge, but cannot accurately represent the number of activated sludge microorganisms. At the same time, a certain amount of laboratory equipment is required in actual operation. In the activated sludge method, the sludge in different periods The specific oxygen consumption rate (SOUR) is different, and the change of water quality characteristics and sludge properties can be judged according to the chang...

Problems solved by technology

[0002] Common indicators of sludge activity include mixed liquid sludge concentration (MLSS), specific oxygen consumption rate (SOUR) and sludge settling ratio (SV), total weight of activated sludge solids (MLSS) and organic solids in activated sludge. The ratio of the total weight of substances can represent the relative value of activated sludge, but cannot accurately represent the number of activated sludge microorganisms. At the same time, a certain amount of laboratory equipment is required in actual operation. In the activated sludge method, the sludge in different periods The specific oxygen consumption rate (SOUR) is different, and the change of water quality characteristics and sludge properties can be judged according to the change of the specific oxygen consumption rate (SOUR), but the specific oxygen consumption rate (SOUR) is easily affected by the type of water quality and toxic substances. The electrodes and dissolved oxygen meters used in the active specific oxygen consumption rate (SOUR) detection method may limit the number of water samples and reduce the possibility of repeated testing. The sludge sedimentation ratio (SV) can relatively reflect the amount of sludge, The coagulation and settling performance of sludge cannot truly reflect the activity of sludge. To a certain extent, pH can reflect the activity of sludge, but the range of pH changes in microbial systems is relatively wide, and pH changes cannot accurately reflect changes in sludge activity.

[0003] Microorganisms play an important role in the treatment process. According to the microorganisms in the activated sludge, the quality of the activated sludge can be found. The existing sludge activity indicators are insufficient. In the actual sewage treatment process, they can be used to Judging whether the sludge activity is affected is not an effective indicator to characterize the sludge activity. The existing detection methods for sludge activity indicators all have the disadvantages of long detection time, the use of various laboratory instruments, high detection cost, low efficiency, It requires personnel with certain professional skills to operate, delays in feedback of test results, and problems that information cannot be shared
