摘要:
为探究影响硫酸盐还原菌（sulfate-reducing bacteria，SRB）降解污泥还原SO2-4的主要因素，构建广义灰色关联度评价模型，并对变量的重要度进行排序。研究结果表明：在一定条件下，SO2-4还原率随温度及初始pH值的上升呈现先增长后降低的趋势，随氧化还原电位的上升呈现不断降低的趋势；温度，初始pH，氧化还原电位的综合关联度分别为0.690，0.755，0.537，影响SO2-4还原率因素大小顺序为初始pH>温度>氧化还原电位。研究结果可为污泥处理过程中控制硫化氢的释放提供理论支持，并为避免或减少污泥产硫化氢导致的人员伤亡和财产损失提供思路。
Abstract:
In order to investigate the main factors influencing the reduction of SO2-4 in sludge degraded by sulfate-reducing bacteria,a generalized grey relational evaluation model was constructed,and the importance of variables was ranked.The results show that under certain conditions,the SO2-4 reduction rate increases first and then decreases with the rise of temperature and initial pH,and decreases with the rise of oxidation reduction potential.Meanwhile,the comprehensive correlation degrees of temperature,initial pH,and oxidation reduction potential are 0.690,0.755,and 0.537,respectively,and the magnitude of the factors influencing the SO2-4 reduction rate is in the order of initial pH > temperature > oxidation reduction potential.The results can provide theoretical support for controlling the release of hydrogen sulfide during sludge treatment,and can also provide ideas for avoiding or reducing human casualties and property damage caused by hydrogen sulfide production from sludge.
