Introduction of an example fo r azo dyes wastewater by adsorption A/O process.The wastewater is treated by neutralizat ion precipitat ion adsorption, 29.7 %COD is removed.When the wastewater is treated by UASB reactor, 58.9 %COD is removed, and g ranular sludge is formed in UASB reactor.When the UASB reactor effluents go through aerobic membrane biological reactor, 80.7 %COD is removed.COD of secondary settling tank eff luent can be reduced to below 150 mg/ L, meeting the first grade of integrated wastewater discharge standard.
