A sufficient feed rate ( higher than the lowest flow rate), an appropriate sludge charge and an equal distribution of feed as well as a suitable alkality in medium are the main factors for the scale up and process control of UASB 合适的进料速率、污泥负荷、布水均匀性以及碱度控制是UASB反应器工程放大和过程控制的四大要素
In order to calculate the maximal electric field under high voltage transmission lines of multiple-way feed system, the generalized mathematical models were established based on frequency-domain and time-domain with charge equivalent method, and the formulas of the maximal electric field were deduced. 为了准确计算多路供电系统高压输电线下空间点的最大场强值,采用等效电荷法,分别基于频域和时域建立了其广义数学模型,并推导出了最大场强计算公式。
When feed pH was less than 7, the amines and imines of PANI were protonated and PANI/ PS membrane surface had positive charge. 当进水pH值小于7时,复合膜表面的氨基和亚氨基会被质子化,膜表面带正电荷。
