生物预处理去除有机物的特点

open access: yesGongye shui chuli, 2005
试验对正在运行的生物预处理以及后续处理工艺进行了调查,了解了生物预处理的出水有机物变化以及对后续处理工艺的影响。试验表明:由于微生物新陈代谢产物溶解在水中的缘故,生物预处理出水会出现有机物增加的现象,影响了后续处理工艺的去除效果。对出水进行的分子质量分布测试表明,微生物新陈代谢产物会产生大量的消毒副产物。生物预处理无法降低水的致突变性。

某精细化工企业废水处理工程实例

open access: yesGongye shui chuli, 2023
针对某精细化工企业生产废水的不同水质特点,将废水进行分类收集,根据不同处理需求,选择“蒸馏+隔油+Fenton氧化”工艺对高盐废水、树脂脱附废水进行预处理,选择“隔油+Fenton氧化”工艺对高浓废水、废气洗涤水进行预处理,预处理后废水再与其他低浓水按照一定比例复配,满足生化进水要求后,采用“水解酸化+两级A/O+混凝沉淀”工艺处理综合废水。该工艺不仅适合较复杂的水质处理,还适合应对波动性大的生产工况;预处理效果显著,综合出水可稳定达标。实际运行效果证明,综合废水COD、氨氮、总氮去除率分别达到85 ...

Evaluating models of expert judgment to inform assessment of ecosystem viability and collapse

open access: yesConservation Biology, Volume 39, Issue 2, April 2025.
Abstract Expert judgment underpins assessment of threatened ecosystems. However, experts are often narrowly defined, and variability in their judgments may be substantial. Models built from structured elicitation with large diverse expert panels can contribute to more consistent and transparent decision‐making.

Fenton试剂-浸没式生物滤池处理模拟染料生产废水试验研究

open access: yesGongye shui chuli, 2006
作者采用Fenton试剂预处理和浸没式生物滤池联合法处理含盐较高的模拟染料生产废水,考察了Fenton试剂预处理对染料结构的破坏作用和染料液可生化性的改善作用及浸没式生物滤池对预处理后溶液CODCr的去除过程和处理效果。实验结果表明,Fenton试剂预处理能有效破坏染料分子的结构,色度去除率可达99%;预处理后染料液的可生化性得到显著改善;浸没式生物滤池对预处理后的染料废水CODCr的去除效果稳定,平均去除率达到64%,且具有一定的抗冲击负荷能力。
