OUR-based activated sludge bulking early-warning and analyzing system and using method thereof

Abstract

The invention discloses an OUR-based activated sludge bulking early-warning and analyzing system. The OUR-based activated sludge bulking early-warning and analyzing system comprises a sewage filter, asewage pump, an aeration tank, an aeration device, a sealed reaction tank, a separating plate, various biogels, DO electrode probes, a PLC early-warning system and a water outlet, wherein the numberof the DO electrode probes corresponds to the number of the biogels; a water inlet of the sewage filter is connected with a water intake in a connecting pipeline of a pretreatment system and a biochemical pool; the sewage pump is connected with the sewage filter and the aeration tank; a water outlet of the aeration tank is connected with the sealed reaction tank; the biogels include filamentous bacteria biogel, zoogloea biogel, low-temperature biogel, low-pH biogel, low-N biogel, low-P biogel, high-H2S biogel and multi-soluble organic biogel, and the biogels are placed in different separationareas respectively and are detected by means of the DO electrode probes; a water outlet of the sealed reaction tank is connected with the pretreatment system. The OUR-based activated sludge bulking early-warning and analyzing system has the functions of real-time and multi-level warning of sewage and real-time analysis of the causes of sludge bulking.

Description

technical field [0001] The invention relates to an OUR-based activated sludge bulking early warning analysis system and a use method thereof, and belongs to the technical field of real-time early warning of activated sludge imbalance in sewage treatment. Background technique [0002] With the development of my country's economy and society, especially industry, a large amount of untreated industrial wastewater mixed with domestic sewage is discharged into urban sewage treatment plants, causing fluctuations in the quality of influent water, which has an impact on the stable operation of the treatment process. In particular, the existing urban sewage treatment plants in my country widely adopt the activated sludge process. The activated sludge system will cause imbalance and failure due to the impact of toxic and harmful substances contained in the sewage, and problems such as sludge bulking and sludge disintegration will occur. Real-time early warning of water quality fluctuat...

AI Technical Summary

Problems solved by technology

[0005] (1) The existing OUR biotoxicity monitoring system does not have comprehensive warnings, and can only warn of the reduction of the respiration rate of the activated sludge system caused by sewage, but the impact of water quality fluctuations on sludge is not limited to all microbial communities in sludge Inhibition of this situation may also lead to an imbalance of activated sludge microorganisms

For example, changes in the water quality of sewage may promote the excessive reproduction of filamentous bacteria, and the respiration rate of the entire activated sludge system may not change or even increase, but the activated sludge system has expanded, resulting in poor water quality

[0006] (2) The existing OUR biological toxicity monitoring system draws water from the biochemical pool, and the sewage has already entered the biochemical pool, resulting in untimely early warning

Extracting sludge from the biochemical tank will also have a certain impact on the morphology and microbial activities of the activated sludge system
