摘要:

采用微生物培养菌落计数法研究了使用聚环氧琥珀酸水处理剂时水中PESA、磷、通气量、初始菌数及pH值对异养菌繁殖的影响,结果表明:PESA使用浓度较低时对异养菌繁殖影响较小,浓度增加促进异养菌生长期繁殖;磷酸盐促进异养菌稳定期繁殖;通气对异养菌生长繁殖影响不明显;初始菌数对异养菌繁殖的稳定期影响不明显pH值对异养菌的生长繁殖影响较大。

Abstract:

The effects of polyepoxysuccinic acidPESA),phosphorusventilationinitial amount of heterotrophic bacteria and pH value on the growth of heterotrophic bacteria in the water using PESA as a water treatment agent were studied by the flat-dish numeration method. The results showed that PESA had little influence on the breeding of heterotrophic bacteria at a low concentrationwhile it promoted the growth rate of heterotrophic bacteria as its concentration increased. The higher the concentration of phosphatethe more the amount of heterotrophic bacteria in the stable breeding period. Ventilation had no effect on the growth of heterotrophic bacteria. The initial amount of heterotrophic bacteria had little influence on the amount during the balance period. The pH value had a significant impact on the breeding of heterotrophic bacteria.
