AI Technical Summary

Technical Problem

The existing anaerobic ammonia oxidation process operation monitoring lacks low-cost automation technology, and the existing online monitoring indicators cannot accurately reflect the denitrification activity of sludge. The determination of nitrogen indicators relies on offline manual sampling and professional chemical analysis, which is time-consuming and labor-intensive.

Method used

The automatic acquisition device of anaerobic ammonia oxidized sludge based on image processing and the nitrogen removal activity monitoring method are adopted. By combining the biological reaction zone and the image acquisition zone, automatic acquisition and image processing of the sludge are realized to monitor the nitrogen removal activity of the sludge.

Benefits of technology

Automatic monitoring and analysis of anaerobic ammonia oxidized sludge is realized, which reduces monitoring costs and improves detection efficiency. It can intuitively, comprehensively and accurately evaluate the activity of sludge, and avoids the time and manpower consumption of traditional methods.

Abstract

The invention provides an anaerobic ammonia oxidation sludge automatic collection device based on image processing and a denitrification activity monitoring method thereof, and relates to the field of biological sewage treatment. The device comprises a biological reaction area I used for culturing anaerobic ammonia oxidation sludge, and regularly and automatically transmitting a sludge-water mixed solution to an image acquisition area II, so as to complete image acquisition, image processing and activity monitoring. The sludge pump regularly discharges sludge-water mixed liquid into the culture dish, the industrial personal computer controls the industrial microscope to continuously collect microscopic images of sludge in the culture dish, the sludge reflux pump returns the sludge-water mixed liquid into the anaerobic ammonia oxidation reactor, and the flushing pump conveys supernate in the effluent interception device into the culture dish to complete secondary flushing. In order to solve the problem that the anaerobic ammonia oxidation process lacks a low-cost automatic monitoring means, the invention provides a novel method for auxiliary monitoring of the operation of the anaerobic ammonia oxidation process based on image processing.
