The results of the microorganism test also showed that, biological grid filler could obviously increase the amount of heterotrophic bacteria, especially the amount of nitrobacteria, and improved the pollution removal effect. 微生物测试结果表明,生物栅填料可以显著增加异养细菌特别是硝化细菌的数量,增强污染净化效果。
The use of this bactericide alone or in combination with chlorine gas in sterilizing heterotrophic bacteria in circulating water is 100% up to standard and does not affect the inhibiting effect of organophosphorus corrosion inhibitor. 该杀菌剂单独投加或与氯气联合使用杀灭循环水中异养菌的合格率达100%,且不会影响有机膦缓蚀剂的缓蚀作用。
The heterotrophic nitrification bacteria existed in MBR system possessing SND effect of 80% was isolated and cultured; and its mortifying characteristic was studied. 对具有80%的同步硝化反硝化(SND)效果的MBR系统中存在的异养硝化菌进行了分离培养,并对其硝化特性进行了研究。
