摘要
高盐度废水微生物燃料电池（MFCs）采用连续流培养模式,以不同化学需氧量（COD）的高盐度废水为燃料,观察MFCs电压的变化和MFCs电压对不同高盐度废水的响应时间,并提出构建生物传感器的构想。结果表明,当COD浓度〉290 mg/L时,输出电压值维持在162-168 m V之间;当COD浓度〈290 mg/L时,输出电压值随COD浓度变化,两者之间满足直线方程,y=0.53x,其中y为电压,x为COD浓度,相关系数为0.986;MFCs对COD浓度〈290 mg/L的高盐度废水感应灵敏,更换不同浓度的高盐度废水,电压的响应时间为0.8-4 h。为高盐度低COD浓度废水提供了一种新的检测方法,方便、快速。
The high salinity wastewater was used as the substrate of microbial fuel cells（ MFCs） by the continuous-flow mode. Different concentrations of chemical oxygen demand（ COD） of the high salinity wastewater were adopted to observe the change of output voltage value of MFCs and response time. Then,an idea of biosensor was put forward. Results showed that when the concentration of COD was more than290 mg / L,the value of output voltage kept steady state,from 162 - 168 m V. When COD concentration was less than 290 mg / L,a linear relation between voltage and COD fit the equation of a straight line well,y = 0. 53 x,where y is the voltage,x is the COD concentration,R2 is 0. 986. When COD concentration was less than 290 mg / L,MFCs were sensitive and the value of output voltage kept steady state after 0. 8 -4 h. The biosensor provides a new test method of COD which is more convenient and faster.
