微生物处理污水同步发电工艺及建模分析研究

Study on Synchronous Electric Power Generation Process and Modeling of Microbial Treatment

本项目旨在提出一个可行的微生物处理污水同步发电工艺方案。以单室空气阴极式微生物燃料电池装置作为研究对象,装置连续运行一个月,污水的CODCr去除率约为52.2%、TP去除率约为87.3%、TN去除率约为42.7%、最大输出电压为0.677 V,在电流密度约为0.2 W/m^2时,功率密度达到最大值0.18 A/m^2。污水处理效果良好,但是对外输出电力效能较低,说明该工艺存在一定的问题。若问题能得到改进,本项目设计将成为一种可行的微生物处理污水同步发电工艺方案。

The project aimed to propose the synchronous process that generating electric power by the microbialtreatment of sewage. The single-chamber and air-cathode microbial fuel cell were used as the object of research and hadrun continuously for a month. CODc, removal rate of the effluent was about 52.2%, TP removal rate was about 87.3% ,TN removal rate was about 42.7% . When the current density was about O. 2 W/m2, the power density reached amaximum of 0. 18 A/m2. The effect of sewage treatment was good, but the efficiency of electricity output was low whichindicated that there were some problems in the process. If the problems can be improved, the design of this project will bea viable microbial treatment of sewage synchronous electric power generation process.
