Problems solved by technology
Because the microbial community in the activated sludge treatment system is very complex, and the biochemical reaction process is nonlinear and changeable, the traditional sludge indicators cannot fully and accurately reflect the activity changes of nitrifying bacteria and denitrifying bacteria in biological sludge. , this kind of judgment method not only takes a long time, but also has hysteresis, and cannot fully reflect the activity and degradation ability of nitrifying bacteria and denitrifying bacteria. The control strategy based on this judgment method is blind
The use of such judgment methods and traditional sludge indicators will lead to poor treatment effect and low efficiency of the sewage treatment system, and cannot reflect the actual state of activated sludge

The invention discloses a device and method for automatically monitoring biological sludge activity based on multiple parameters in the technical field of sewage treatment. The device for automatically monitoring biological sludge activity based on multiple parameters includes a pre-aeration system, a mixed reaction system, a measurement system, a control and a data processing system, and the mixed reaction system is respectively connected with the pre-aeration system and the measurement system; control and data processing The system controls the movable parts of the pre-aeration system, mixed reaction system, and measurement system, and collects and processes data online. Through the device and method for automatically monitoring biological sludge activity based on multi-parameters, the respiration rate can be measured online 24 hours a day, and the nitrification activity and denitrification activity of the activated sludge can be characterized, and then the biological sludge can be more intuitively understood. The activity changes of nitrifying bacteria and denitrifying bacteria provide a basis for controlling the nitrification and denitrification process in the activated sludge treatment system.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a device and method for automatically monitoring biological sludge activity based on multiple parameters. Background technique [0002] Most of the sewage treatment system is mainly based on activated sludge treatment, and the traditional biological denitrification process is often used to reduce the concentration of nitrogen compounds in the effluent. The principle of biological denitrification process is to convert ammonia nitrogen into nitrate nitrogen through the growth and metabolic activities of microorganisms, and then convert it into nitrogen gas and remove it from water. The former is called nitrification process, which mainly occurs under aerobic conditions and requires oxygen supply as electron acceptor; the latter is called denitrification process, which occurs in anoxic environment and requires organic carbon source as electron donor. The coordination of ni...
