新型氧化-混凝剂处理染料废水研究

open access: yesGongye shui chuli, 2003
根据染料废水的特点,研究了自制产品新型氧化-混凝剂处理染料废水的情况,探讨了药剂用量、pH值等因素对COD、色度去除率的影响。试验表明,当pH大于10,"染清"氧化-混凝剂的质量分数为0.03%,絮凝时间6min,静置沉淀35min时,该药剂对染料废水具有良好的处理效果,COD和色度的去除率最高分别可达97%和86%,从而证明该方法对于染料废水的处理是可行的。该处理工艺设备简单,系统运行稳定,操作方便,成本低。

活性黑5染料生物脱色产物的电化学氧化探究

open access: yesGongye shui chuli, 2022
印染行业使用的染料多为化学合成染料,其中以偶氮发色团为基础的合成染料约占80%。作为具有代表性的偶氮活性染料之一,活性黑5(RB5)常用于棉花、其他纤维素纤维、羊毛和尼龙的染色。偶氮染料废水中含有大量难降解的有机物。除脱色外,对废水中的染料与中间产物进行降解矿化、降低毒性,也是偶氮染料废水的处理目标。针对RB5经微生物脱色后的产物难以生化降解的特点,对生物膜反应器出水毒性进行监测,结果表明RB5废水经微生物脱色后仍有残留毒性。采用钛基金属氧化物涂层为阳极材料的电化学装置对含RB5脱色产物的废水进行处理 ...

CuO-H2O2非均相催化氧化染料废水

open access: yesGongye shui chuli, 2013
以活性艳红X-3B为模拟底物,研究了低温常压条件下CuO-H2O2体系催化氧化染料废水的各种影响因素及反应机制。结果表明,CuO-H2O2体系能高效彻底地氧化活性艳红X-3B,氧化率可高达99%。CuO-H2O2体系降解染料废水的速率随温度、氧化剂和催化剂投加量以及X-3B废水初始浓度的升高而升高。酸性条件能促进X-3B废水的降解。与直接染料相比,CuO-H2O2体系降解活性染料废水更加有效。

Thermite‐Synthesized Fe–Ti–Al–Mg High‐Entropy Intermetallic Compound for Efficient Azo Dye Degradation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

直接染料染色废水的脱色及其回用

open access: yesGongye shui chuli, 2003
使用还原型脱色剂对直接染料染色废水进行脱色处理,重点研究了脱色剂用量、反应温度、pH和时间等因素对脱色反应的影响。并且将脱色后的染色废水回用于织物染色中,在染色织物的颜色特征和牢度方面进行了比较。结果表明,脱色温度的升高有利于染料的脱色,尤其对于水溶性较差的品种,脱色剂用量的增加能够促进染料的脱色率的升高。另外三种染料在自来水和回用水中的的染色织物的染色表面深度和牢度比较接近,而且染色织物之间的色差较小,这说明脱色废水可以回用于直接染料的染色中。

Surface Sulfate Modification Promoted Excitons Extraction of BiOBr Nanosheets for Efficient 1O2 Photosynthesis and Chlorophenols Dechlorination

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−
