VFA abbr. 挥发性脂肪酸(Volatile Fatty Acid);视频放大器(Video Frequency Amplifier)
- The varieties of VFA along the reactor makes it clear that the acidogenic and methanogenic are separated in the ABR.
反应器中VFA沿程浓度的变化表明,在反应器中存在产酸相和产甲烷相的分离。 - Vendor should submit shell fabric swatch and shade band in all color way of both before and after wash to VFA for approval.
供应商应提交洗水前和后贝壳布样板和缸差样的全部颜色供批核。 - The results show that lack of carbon source,especially VFA,in the influent and shorter anaerobic HRT are key factors to limit nutrient removal.
结果表明,进水中的碳源特别是挥发性脂肪酸(VFA)不足和厌氧水力停留时间(HRT)太短是导致脱氮除磷效果不佳的主要原因。
