黑曲霉、荧光假单胞菌去除污水中重金属试验研究
Removal of Heavy Metals from Urban Sewage by Aspergillus Niger and Pseudomonas Fluorescens
摘要
Abstract
Aspergillus niger and Pseudomonas fluorescens were inoculated to the activated sludge in order to improve the removal effectiveness of the oxidation ditch. The comparative experimental study were car ried out when the Hydraulic Retention Time (HRT) was 36 h, and six different HRT of 12 h, 16 h, 20 h, 24 h, 28 h, and 32 h were considered to study the adsorption degradation of Cd, Cr, Pb and Cu by Asper gillus niger and Pseudomonas fluorescens in the oxidation ditch. The result indicated that each of the two strains removal efficiency of the four heavy metals compared with the control group was significantly im proved, and the removal increased with the increasing HRT. When the HRT was 20 h, the removal effi ciency of the four heavy metals by the Aspergillus niger were found to be in the range of 52％ to 91％, and the removal efficiency by Pseudomonas fluorescens reached 70％. Most of the heavy metals can be degrad ed in the HRT of 20 h, and this time parameter is exactly the conventional design parameters of oxidation ditch. It can be say that the degradation efficiency of adsorption of heavy metals can be significantly im proved when inoculated with Aspergillus niger and Pseudomonas fluorescens to the traditional carrousel oxidation ditch process.关键词
