摘　　要：为了研究球红假单胞菌与枯草芽孢杆菌对选煤厂循环水中残留聚丙烯酰胺复合降解效果的影响,以降解率为评价指标,采用正交试验法对球红假单胞菌与枯草芽孢杆菌对选煤厂循环水中残留聚丙烯酰胺的降解效果进行了研究。结果表明:球红假单胞菌和枯草芽孢杆菌都可以降解循环水中残留的聚丙烯酰胺,单一菌种添加时降解率分别为24.9%、22.13%。球红假单胞菌和枯草芽孢杆菌复合降解时降解效果更好,且各因素对试验结果影响显著性有明显不同。最优试验条件下,球红假单胞菌与枯草芽孢杆菌复合降解循环水中残留聚丙烯酰胺的降解率为39.24%。In order to study the effect of rhodopseudomonas palustris and bacillus subtilis on the degradation of residual polyacrylamide in the circulating water of the coal preparation plant,the degradation rate was used as the evaluation index.The orthogonal test method was used to detect rhodopseudomonas palustris and bacillus subtilis.Bacillus has studied the degradation effect of residual polyacrylamide in circulating water of coal preparation plant.The results showed that both rhodopseudomonas palustris and bacillus subtilis could degrade the residual polyacrylamide in the circulating water.The degradation rate of the single strain was24.9%and22.13%,respectively.The combined degradation of Rhodopseudomonas globosum and Bacillus subtilis resulted in better degradation,and the influence of various factors on the test results was significantly different.Under the optimal experimental conditions,the composite degradation cycle of Rhodopseudomonas palustris and Bacillus subtilis was degraded.The degradation rate of residual polyacrylamide in water was39.24%.
