Abstract

The invention relates to a sewage biological treatment reactor and a treatment method thereof, mainly comprising a reactor body and an external circulation system, the external circulation system mainly comprising a circulation pipeline, a circulation pump and a sampling container, and the sewage is discharged from the bottom of the reactor through the circulation pump It flows through the circulation pipeline, and then enters the sampling container, which is located higher than the highest liquid level of the reactor, and the sewage is circulated back to the reactor after sampling. The invention can solve the problem of monitoring pipeline blockage, improve sampling accuracy, ensure the effect of sewage monitoring, improve the problem of insufficient circulation at the bottom of the bioreactor, and improve the efficiency of sewage monitoring and sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of sewage biological treatment, and in particular relates to a sewage biological treatment reactor and a treatment method thereof. Background technique [0002] In sewage treatment systems, regular sampling of sewage treatment facilities is required for monitoring. The water intake end of the existing sewage treatment monitoring system is usually immersed directly in the sewage. When taking water samples, due to the large amount of debris in the sewage, the water sample detection is inaccurate, and the water intake port is often blocked, so that the water samples cannot be obtained smoothly. You need to manually clean and dredge the water intake pipe. In some reaction facilities, in order to avoid the blockage of the sampling water pipe, various filter components are designed inside the reactor, but the filter components still need to be backwashed regularly, and the effect of backwashing is difficult to en...
