Membrane active carbon bioreactor (MACBR) with sedimentation basin

Abstract

The invention relates to a membrane active carbon bioreactor (MACBR) with a sedimentation basin and discloses a water treatment technology for treating organic pollutant effluents by the combination of microorganisms, a sedimentation basin, activated carbon and an ultrafiltration membrane. By utilizing the combination of the microorganisms, the sedimentation basin as well as the activated carbon and the ultrafiltration membrane in a membrane pond, higher treatment efficiency, longer membrane service life, lower energy consumption and cleaner treating water can be obtained.

Description

Technical field: [0001] A water treatment technology that uses microorganisms, sedimentation tanks, activated carbon and ultrafiltration membranes to treat high-concentration refractory organic matter polluted wastewater such as domestic sewage, slaughterhouse wastewater, printing and dyeing wastewater, and textile wastewater. The purpose of treatment is to make the treated water meet the discharge standard or reuse standard stipulated by the state. Background technique: [0002] Membrane bioreactor (MBR) is an efficient water treatment technology developed in recent years. In order to maintain a high-efficiency treatment capacity, the traditional membrane bioreactor believes that under the isolation of the membrane, there is no need to keep the sedimentation tank, and the mud-water mixture in the biochemical tank can maintain a high sludge concentration. However, in practice it is found that the membrane flux will decrease under high sludge concentration. In order to main...

AI Technical Summary

Problems solved by technology

In order to maintain a certain level of membrane flux, the current method is to strengthen the blowing intensity of the membrane with air, which results in an increase in energy consumption and a reduction in the service life of the membrane.
