摘要
采用实验室模拟手段,研究了静态条件下硫酸盐还原菌(Sulfate Reducing Bacteria,SRB)对硫酸盐废水的处理效果,考察了菌液接种量、初始pH、碳源种类、m(COD)/m(SO_4^(2-))等生态因子对处理效果的影响。结果表明,增加菌液量、提升pH、提高m(COD)/m(SO_4^(2-))均可提升SO_4^(2-)去除率;以乳酸钠、葡萄糖、甘油、甲酸作为碳源时,SRB利用这4种碳源对SO_4^(2-)的还原率由大到小依次为甲酸>乳酸钠>甘油>葡萄糖。该研究对SRB处理硫酸盐废水的工程应用具有一定的指导意义。
By means of laboratory simulation,the treatment effect of sulfate reducing bacteria(SRB) on sulfatecontaining wastewater,under static condition,has been studied. The influences of ecological factors,such as microbial inoculation amount,initial p H,carbon sources species,m(COD)/m(SO_4(2-)),etc. on the treatment of sulfate containing wastewater are investigated. The results show that the SO_4(2-) removing rate could be improved by increasing the amount of bacteria,p H and the ratio of m(COD)/m(SO_4(2-)). Using sodium lactate,glucose,glycerol and formic acid as carbon sources,the SO_4(2-) recovering rate sequence,of the four kinds of carbon sources,from high to low,are as follows:formic acidsodium lactateglycerolglucose. The research on the application of SRB to the treatment of wastewater containing sulfate has certain directive significance.
