摘要
当含低浓度的硝酸盐的高浓度有机废水中厌氧生化降解时,硝酸盐转化过程中首先发生的是氨化作用;随着水解酸化产生挥发性脂肪酸VFA,硝酸盐开始发生反硝化作用,并越来越明显,逐步占主导作用。整个过程对处理效率产生一定的影响。即便是低浓度的硝酸盐,仍可能对厌氧系统产生影响。
When anaerobic biodegradation of organic wastewater containing low concentrations of nitrate was occurred,the ammonification was occurred firstly.As volatile fatty acids（VFA） produced by hydrolytic acidification,denitrification played the role of the main mechanism step by step.In the nitrate transformation process,denitrification had more impact on the removal rate of anaerobic system.The efficiency was affected through out the whole process.Even low concentrations of nitrate,it may still have an impact on the anaerobic system.
