Barrel Carbon Steel Domestic Sewage MBR Treatment System

Working principle

The membrane bioreactor (MBR) process is a new type of organic combination of membrane separation technology and biotechnology
Wastewater treatment technology. It uses membrane separation equipment to trap activated sludge and macromolecular organic substances in the biochemical reaction tank, eliminating the need for a secondary settling tank. As a result, the concentration of activated sludge is greatly increased, the hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, and the non-degradable substances continue to react and degrade in the reactor. Therefore, the membrane bioreactor (MBR) process greatly enhances the function of the bioreactor through membrane separation technology. Compared with traditional biological treatment methods, it is one of the most promising new technologies for wastewater treatment.

Equipment performance parameters

The core component of MBR integrated equipment is the membrane bioreactor, and its inlet water quality requirements are as follows: COD<500mg/L
BOD5<300mg/L
SS<100mg/L
NH3-N<50mg/L
Number of Escherichia coli<10000/L
The integrated equipment can flexibly configure the process flow according to the raw water quality, so that the equipment has a wide range of applicability. It can directly treat domestic sewage and hospital sewage to meet the domestic miscellaneous water standard.
