膨胀颗粒污泥床厌氧反应器处理化学制药废水研究

open access: yesGongye shui chuli, 2020
考察了膨胀颗粒污泥床厌氧反应器(EGSB)在不同运行条件下对化学制药废水的处理效果。结果表明:在容积负荷为2.3~15.5 kgCOD/(m3·d)的范围内,EGSB的COD去除率和甲烷产率呈现先升高后下降的趋势,并在容积负荷为11.6 kgCOD/(m3·d)时达到最高,分别为90.5%和4.12 L/(L·d)。在容积负荷为11.6 kgCOD/(m3·d)条件下,降低进水碳硫比能够导致系统COD去除率和甲烷产率的下降,最佳碳硫比为8.0。

两级BAF处理高浓度尿素废水影响因素研究

open access: yesGongye shui chuli, 2010
采用两级BAF处理某石化厂高浓度冷凝液废水,考察了尿素容积负荷、氨氮容积负荷、pH及滤床高度对两级BAF去除尿素效果的影响。结果表明,BAF处理高浓度尿素废水可行,当进水平均尿素容积负荷、氨氮负荷分别为6.92、0~3 kg/(m3·d),pH为7.0~11.0时,两级BAF对尿素的去除率<85%。

曝气生物滤池处理低浓度生活污水的研究

open access: yesGongye shui chuli, 2003
针对南方特有的低浓度生活污水,研究了在低曝气条件下,气水比、水力负荷、进水有机负荷、碳氮比、填料层高度等因素对曝气生物滤池容积负荷的影响。结果表明,在气水比为3~1,碳氮比为3~4,水力负荷为1.1m3/(m2·h)条件下,CODCr和氨氮的去除率分别为97.37%和82.28%,出水有机物和氨氮质量浓度分别为3.4mg/L和6.94mg/L。碳氮比对反应器CODCr容积负荷的影响较对氨氮容积负荷的影响更为明显;氨氮的去除率受水力负荷的变化影响较小。

UASB+HTO工艺处理维生素C废水工程实例

open access: yesGongye shui chuli, 2019
针对维生素C生产废水COD高、盐度高、色度高、可生化性差等特点,经过MVR预处理后,采用中温UASB厌氧反应器和HTO好氧工艺处理该废水。结果表明,UASB反应器在温度为(35±2)℃,pH为6~9,COD容积负荷为4.5~6 kg/(m3·d)时,COD去除率达84%以上;HTO好氧反应器在COD容积负荷为0.68 kg/(m3·d),氨氮容积负荷为0.12 kg/(m3·d)时,COD、NH3-N去除率分别在85%、90%以上。最终处理出水可达CJ 343-2010的C级排放标准。

Bi/Bi2O3 Nanoparticles In Situ Embedded in Carbon as Anode Materials for Fast and Long‐Lasting Sodium–Ion Storage

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles

Construction of CoP/Mn2P Heterojunctions via One‐Step Phosphorization Coupled With Hollow Hard Carbon Spheres as Supports: Enabling Ultrastable Long‐Cycle Sodium‐Ion Anodes Over a Wide Temperature Range

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...

ABR-CSTR组合工艺处理黄酒生产废水研究

open access: yesGongye shui chuli, 2016
采用ABR-CSTR组合工艺对黄酒生产废水处理进行了研究。结果表明,采用低负荷启动并逐步提高容积负荷是ABR-CSTR组合工艺成功启动的关键,在温度为(30±2)℃时,COD容积负荷从0.3 kg/(m3·d)增至4.0 kg/(m3·d),历时100 d启动成功。系统总去除率保持在95%~98%,出水平均氨氮、总氮分别为0.57、20.4 mg/L,表明ABR-CSTR组合工艺能有效处理黄酒生产废水。
