Intelligent diagnosis system for running state of wastewater biochemical treatment system and application method of intelligent diagnosis system

Abstract

The invention relates to an intelligent diagnosis system for the running state of a wastewater biochemical treatment system and an application method thereof. The diagnosis system comprises a dynamic information recorder and an intelligent image information processing system, the dynamic information recorder obtains images of the activated sludge sedimentation process in the transparent container at a plurality of preset time points respectively; the intelligent image information processing system carries out image recognition processing on the image photo to obtain activated sludge characteristic data information, and the activated sludge characteristic data information comprises sludge sedimentation characteristics, supernate characteristics, zoogloea characteristics, liquid level floating object characteristics and other data information; and based on the activated sludge characteristic data information, the intelligent diagnosis system generates a current biochemical treatment system operation state diagnosis report and a risk handling strategy. The diagnosis report can provide accurate identification and early warning for the current operation state of the biochemical system; and the risk disposal strategy can provide direction and thought for field operation and maintenance, so that long-term stable operation of the biochemical treatment system is ensured.

Description

technical field [0001] The present application relates to the technical field of wastewater biochemical treatment, in particular to an intelligent diagnosis system for operating status of a wastewater biochemical treatment system and an application method thereof. Background technique [0002] In wastewater treatment, the activated sludge method is an aerobic biological treatment method for sewage treatment. When using activated sludge method to treat wastewater: [0003] First, the wastewater is mixed with the activated sludge (microbes) in the aeration tank and aerated to decompose the organic matter in the wastewater into bioenergy and inorganic matter through the metabolic process of the microorganisms and be degraded or removed; [0004] Subsequently, the activated sludge (microbial) degraded wastewater and the activated sludge in the water enter the secondary settling tank in the form of a mixed liquid, and the activated sludge and other solid substances suspended in ...

AI Technical Summary

Problems solved by technology

[0007] Therefore, only paying attention to the sedimentation ratio and ignoring the sludge properties, sludge sedimentation process and its process information will miss many internal factors that reflect the real operation status of the biochemical system, and cannot evaluate the operation status of the biochemical system objectively, comprehensively and accurately. ;

[0008] At the same time, when only focusing on the sedimentation ratio, the observation conclusion is weak, lacks depth and theoretical basis, and the written expression is single, which is not enough to be used as the basis for judging the operation status of the biochemical system, and it is impossible to give early warning of the potential operation risks of the biochemical system, let alone Propose reliable coping strategies and disposal measures for current system operation failures
