英文翻译-人翻译好的全分!机器翻译的不要进来,不会得分。【专家解说】:老大,专业单词都不给全就让人家翻译,COD就没给
continuity of activated sludg

【专家解说】:老大,专业单词都不给全就让人家翻译,COD就没给 continuity of activated sludge organic (COD) 我还专门去查了这边文章,好辛苦 AD=anaerobic digestion AD=厌氧消化(或无氧消化) ordinary heterotrophic organism= (OHO)普通异养生物(与autotroph相对) WAS= water activated sludge 水活污泥(废水处理的一种方法) 3.2. Determining the unbiodegradable COD fraction of WAS from AD model通过AD模式确定WAS中的非生物降解的COD片段(或碎片之类的) For this the steady state AD model of So¨temann et al. (2005)was used due to its simple direct calculation procedure and equivalence to the complex dynamic simulation AD models for stable methanogenic digesters. 对于使用Sötemann et al的定态AD模版(模式)(Sötemann et al人名)是由于它简便直接的计算步骤和等值于那用于稳定的制甲烷沼气池的复杂动态仿真AD模式(模版)This model is an extension of the McCarty (1974) steady state AD model and comprises 3 parts:此模版是对1974年McCarty模版的扩充,包括3个部分: (1) a COD mass balance-based kinetic part from which the concentration of biodegradable particulate COD hydrolyzed, residual biodegradable COD, AD biomass and methane production are calculated, (1)一个以COD质量平和为基础的动力部分,此部分来自可生物降解的微粒COD水解,剩余可降解COD,AD的生物量和甲烷产量是可计算的(2) a stoichiometry part from which the AD biomass, methane gas, dissolved CO2 (HCO3 Alk), gaseous CO2 and saline ammonia (NH4 +) generated are calculated from C, H, O and N mass balances and the concentration and composition (X, Y, Z and A in CXHYOZNA) of the biodegradable COD (and influent VFA) digested, and (2)化学计量部分,通过C,H,O和N的质量守恒,消化了的可生物降解COD的成分和浓度,来计算生成的AD的生物量,甲烷气体,溶解的CO2,CO2气体,和铵盐(3) an inorganic C weak acid/base chemistry part from which the digester pH is calculated from the partial pressure of CO2 (pCO2 or CO2 mole fraction of the CH4 and CO2 gas stream) and H2CO3* alkalinity (closely equal to HCO3 concentration at pH 7–8). (3)无机的碳化合弱酸/碱部分,此部分来自通过二氧化碳的局部压和碳酸根的碱度来计算的沼气池)的PH值。Because C, H, O and N are conserved in the model, the influent organics concentration and composition completely define the AD outflow products, which in turn fix the digester pH.因为碳,氢,氧和氮的量是守恒的,所以通过流入(投入)的有机物的浓度和成分完全可以明确(得知)产出的产物,以此来确定沼气池的PH。 whew, cheers 参考文献:Biodegradability of activated sludge organics under anaerobi
