An experiment was carried out to use plate–type silicone rubber membrane equipped bioreactor with bubbleless oxygen supplying for the treatment of domestic sewage. The effects of hydraulic load, CODcr entrance concentration and oxygen pressure on the discharge concentrations of CODcr, BOD5 and NH3-N were investigated. The results showed that the discharge concentrations of the three pollutants were 18.6 mg· L-1, 9.33 mg· L-1 and 3.56 mg·L-1 respectively when hydraulic load was 0. 25 m3·m -2·h-1 and entrance concentrations of CODCr , BOD5 and NH3-N were 220 mg·L-1 , 140 mg·L-1 and 45 mg·L-1, respectively. These values are lower than the standard ones regulated in the 《Emission Standards of Municipal Wastewater Treatment Plant 》(GB/18918-2002) issued by Chinese government . The degrading dynamic models of CODcr and BOD5 were established and proved to be basically consistent with the experiment values.

Biological Methods

Many traditional biological methods for the treatment of wastewater cope poorly with toxic, volatile organic compounds. The extractive membrane bioreactor is a novel process for the treatment of industrial wastewaters containing such compounds which combines extraction across a silicone rubber membrane with biodegradation. Previous work has shown that there is a problem in this system with excess biofilm growth on the membrane surface, resulting in reduced flux of organic substrate across the membrane. The work presented here shows that addition of sodium chloride to the biomedium increases the maintenance energy requirement of the degradative microorganisms and results, in a carbon-limited situation, in a reduction in biofilm growth. Flux of organic substrate was shown to remain high under reduced biofilm growth conditions.
