The nutrient requirements for anaerobic microorganisms are different from aerobic requirements because the cell yield is lower.厌氧微生物对营养的需求和喜氧微生物是不同的,因为它们的细胞代谢水平很低.
35 Furthermore,the nitrogen and phosphorus requirements for anaerobic treatment are typically only 20 percent of those for aerobic treatment.
再说,氮磷的厌氧处理只有有氧处理的20%
36 Whereas a COD:N:P ratio of 100:5:1 is typical of aerobic treatment,COD:N:P 比率为 100:5:1 是典型的有氧处理方式.
a COD:N:P ratio of 100:1:0.2 is typical of anaerobic growth.
COD:N:P 比率 100:1:0.2 是典型的无氧处理方式.
37 Specific nitrogen and phosphorus requirements will depend upon the nature of the organic compounds to be biodegraded and the sludge age of the treatment system.
看不懂.
38 In addition to nitrogen and phosphorus,anaerobic microorganisms require other nutrients for growth.
除氮氧之外,厌氧微生物还需要其它营养来维持生长.
