Description

Technical Field

[0001] The utility model relates to the technical field of microbial generators, in particular to a catalytic carrier composite microbial generator for an SBR process. Background Art

[0002] SBR is an activated sludge sewage treatment technology that operates in an intermittent aeration mode, also known as the sequencing batch activated sludge process. Unlike traditional sewage treatment processes, SBR technology uses a time-division operation mode instead of a space-division operation mode, an unstable biochemical reaction instead of a steady-state biochemical reaction, and static ideal sedimentation instead of traditional dynamic sedimentation. Its main feature is the orderly and intermittent operation. The core of SBR technology is the SBR reaction tank, which integrates the functions of influent equalization, primary sedimentation, biodegradation, and secondary sedimentation in one tank, without a sludge return system.

[0003] SBR is a modified version of the traditional AO biochemical wastewater treatment process. The microorganisms that degrade pollutants in wastewater still use activated sludge. However, this process can become unstable when the influent volume and water quality fluctuate. It also has poor anti-interference capabilities and is prone to scum formation, resulting in high operating costs. Our company has developed a catalytic carrier composite microorganism that can replace activated sludge in wastewater biochemical processes.

[0004] The microorganisms used in catalytic carrier composite microbial technology are natural microorganisms selected from nature for wastewater treatment. They have not undergone genetic recombination and are pollution-free, making them an ideal alternative to activated sludge. However, the catalytic carrier composite microorganisms require continuous aeration in the water to operate, otherwise they will enter a dormant state. The SBR process, on the other hand, performs water inlet, aeration, sedimentation, and effluent in a single pool. During the sedimentation phase, the pool is not aerated, and during the effluent phase, the pool is not aerated, and the water level drops to a minimum. The process conditions in these two phases do not meet the working requirements of the catalytic carrier composite microorganisms, so the catalytic carrier composite microorganisms will become dormant and not operate. Utility Model Content

[0011] Preferably, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the retaining ring. By providing the spring, the retaining ring is easy to reset.
