进水浓度
1.
The influence of the concentration of sewage on sludge granularing in the UASB reactor under treating swinefaeces waste water condition;
UASB处理养猪废水条件下进水浓度对污泥颗粒化的影响
2.
The glucose wastewater was treated by EGSB and the influence of COD concentration on the sludge granulation was studied.
实验结果表明:随着进水COD浓度从2 000 mg/L上升到10 000 mg/L,传质过程中进入颗粒内部的营养量逐渐增加,促进污泥颗粒化,颗粒直径也随之增大;进水浓度剧烈变化对反应器造成很大冲击,引起细菌生长过快,污泥结构松散,沉降性能下降,COD去除率和产气率降低。
3.
The effect of sludge loading on biological removal of phosphorus, nitrogen and organic matter was investigated by parallel experiments with changing concentration, flow rate of synthetic wastewater and MLSS.
分别改变进水浓度(C)、流量(Q)及污泥浓度(MLSS),通过对照实验考察污泥负荷改变对污水生物去除有机物、磷和氮效果的影响。
5) concentration levels
浓度水平
1.
An overview of concentration levels for several major groups of EDCs in environmental samples was presented.
文章介绍了环境样品中某些主要类型EDCs的浓度水平,并简要地讨论了EDCs的环境暴露对人类在生殖能力、癌症的发生和甲状腺几个方面健康影响的佐证。

根据近年来二噁英的污染现状,对环境中二噁英的污染浓度水平、污染来源及途径进行了探讨,结果表明:近10年来,二噁英污染浓度水平仍高于检出标准。
2.

利用2002年7月—2003年6月可吸入颗粒物(PM10)20余站点的监测资料,分析获得了北京地区PM10的浓度水平和地域分布特征。
补充资料:浓度分布
在给定时刻的空间某区域内,浓度随位置的变化。这是对质量传递研究的主要问题之一,反应器及传质设备中通常存在着一定的浓度分布。质量传递仅以定态分子扩散方式进行时,浓度分布可通过斐克定律计算;质量传递以对流扩散方式进行时,须解出对流扩散方程。但常因速度分布难以得知,使浓度分布的计算发生困难,只能借助于实验。
浓度分布的表述方式及其应用,与温度分布、速度分布相似。
