| 摘 要： | 以某污水处理厂二沉池好氧污泥为接种污泥,采用逐步提高盐度和稳定盐度2种方法对活性污泥进行耐盐性驯化培养,考察驯化结果表明,前一种方法更有利于耐盐菌的培养。对比不同盐度情况下各项指标的去除效果得出:本实验污泥适宜盐度为1%。使用稳定进水盐度的方法,出水指标及各指标的去除率均低于逐步提高盐度法,且镜检结果表明大量微生物死亡。

| Abstract: | The activated sludge from secondary settling tank in a wastewater plant was salt tolerance acclimated by gradually increasing salinity method and stable salinity method. The result showed that the former method was more conducive to the cultivation of salt-tolerant bacteria. The comparison on the removal efficiencies of the indicators under different salinities indicated that the highest salinity the experimental sludge could tolerate was 1%. The concentration and the removal rate of the effluent indicators using stable salinity method were all lower than using gradually increasing salinity method and the microscopic examination results showed that a large number of microbial were died. |
