仿生植物处理城市生活污水研究

Study on treatment of municipal wastewater by the bionic plants

选择成本相对低廉的3种不同材料构建仿生植物,研究不同材料构建的仿生植物对污染水体的净化效果,筛选出性价比较好的仿生植物材料,并分别进行原位挂膜培养和专有菌株挂膜培养。结果表明,原位培养的生物膜对COD去除效果较好,平均去除率为76.92%;专有菌株培养的生物膜对氨氮的去除效果较好,平均去除率达到了91.47%;2种挂膜方式对TP的去除率较为接近,平均去除率分别为73.04%和70.43%。

Three low cost materials were selected to construct bionic plants. The performance of three bionic plants for municipal wastewater treatment was compared to find the most appropriate and cost-effective bionic plant material. The in-situ biofilm colonization and proprietary strains biofilm colonization were carried out on the most ap- propriate bionic plant materials for municipal wastewater treatment, the results showed that initu cultivation biofilm had high efficiency in COD removal with the average COD removal rate was 91.47%. The TP remove capability of insitu cultivation biofilm and proprietary strains cultivation biofilm was similar, their average TP removal efficiency was 73. 04% and 70.43% respectively.
