Problems solved by technology
These data cannot intuitively and timely explain the changes in the properties of activated sludge itself.
[0005] Second, there will be a serious deviation between the amount of substances indicated by the existing SS instrument and the actual situation, especially after the sludge is bulked or the aging structure of the sludge is loose, it is meaningless to continuously compare this data
[0006] Third, the properties of activated sludge are still unable to get rid of the manual testing work, the workload of manual testing is heavy and the data is insufficient, and the application of production management often lags behind

Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.
[0043] like figure 1 Shown, the flow process of a kind of activated sludge performance index online monitoring method of the present invention is as follows:
[0044] Step 1: Scan the activated sludge samples collected in the test dish layer by layer to obtain sludge concentration data at different layer heights and at different times.
[0045] Evenly set multiple monitoring points along the height direction of the detection dish;
[0046] An annular photoelectric detection ring is arranged outside the detection dish, and the photoelectric detection ring is controlled to move at a constant speed along the height direction of the detection dish;
[0047] Whenever the photoelectric detection ring moves to a monitoring point, the h...

The invention relates to the technical field of sewage treatment, in particular to an online monitoring method for activated sludge performance indicators. Scan the activated sludge samples collected in the test dish layer by layer to obtain sludge concentration data at different layer heights and at different times; according to the sludge concentration data at different layer heights and at different times, establish the sludge at different layer heights at different periods Concentration matrix; drawing a time-layer height-concentration sludge settlement hologram according to the sludge concentration matrix; drawing a time-layer height-concentration sludge characteristic fingerprint according to the sludge concentration matrix. By scanning the activated sludge sample layer by layer, the continuous collection of sedimentation data is realized, and the sludge sedimentation hologram and sludge characteristic fingerprint map are drawn. Through the sludge sedimentation hologram, the whole sedimentation process of the sludge can be visually observed, and the activated sludge The online monitoring of the sludge shape index greatly facilitates the operators to understand the changes in the sludge properties and improves the efficiency of the activated sludge water treatment process management.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an online monitoring method for activated sludge performance indicators. Background technique [0002] The activated sludge method plays an important role in the field of sewage treatment. The stability of sewage treatment effect is closely related to the properties of activated sludge. Therefore, it is very important to quickly and accurately grasp the properties of activated sludge. [0003] At present, the activated sludge process is to control the sludge concentration and concentration of the biochemical tank and the secondary sedimentation tank. On-line monitoring is indicated by the ratio of suspended solids in biochemical pools to 30-minute sedimentation. There are several problems: [0004] One is that the biochemical tank online data collected in the current activated sludge process is the concentration of the fully mixed suspended matter at a point in a relat...
