, 2003 一种用于处理工业过程中所产生的高含硫量、高浓度的有机废水的方法是将稀释后的该种废水首先用于湿式空气氧化法进行预处理，在反应温度：255-260℃；反应压力6.6-7.0MPa；气/水(体)：200-260小时-1；空速：1.0-1.3小时-1的反应条件下，COD的去除率可达到74-76％。预处理后的废水再用电多相催化氧化法进行后续处理，在电流：1.0-2.5A；电压：6-12V；处理时间：1-7h的反应条件下，COD的去除率可达到60-68％。这样废水经过湿式氧化与电多相催化氧化的联用技术处理后 ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Aqueous zinc batteries hold great promise for large‐scale energy storage, yet their practical application is hindered by dendrite growth and interfacial side reactions on the zinc anode. Inspired by the industrially mature chromate passivation technology, this work reports an in situ construction of a chromium‐rich passivation layer (Zn@Cr) on

, 2019 针对煤气化过程形成的废水量大、成分复杂、污染物含量较高,且因煤种、气化工艺不同而成分变化,处理难度很大的特点,研究采用冷冻浓缩技术对Texaco和Lurgi法气化废水进行处理。结果表明,采用冷冻浓缩技术可以将气化废水中的有机物和无机物基本脱除,产水的COD不超过10mg/L,COD和电导率符合HG/T3923-2007循环冷却水用再生水水质标准,不易受进水中钙离子含量的影响。处理Texaco和Lurgi气化废水的产水率分别超过90%和95%,可显著提高废水回用率,并降低废水处理量 ...

Shuitu Baochi Xuebao, 2011 采用盆栽试验方法,以不施赤泥为对照,分析不同赤泥施用量对Cd污染稻田水稻产量和土壤生物性状的影响。结果表明,施适宜用量赤泥能提高水稻有效穗和促进水稻生长,实现水稻增产,与不施赤泥处理相比,RM-2处理(0.5%赤泥)的水稻株高、有效穗、结实率和水稻产量分别提高了3.40%,4.20%,3.87%和6.86%。从分蘖期到成熟期,施用赤泥处理各生育期的水稻土微生物量碳、氮明显高于对照RM-0处理的。其中,RM-2处理(0.5%赤泥)各时期水稻土微生物量C(SMBC)、微生物量N(SMBN)都明显高于RM ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT In MAX‐phase‐derived metal–matrix composites, the M‐site element simultaneously governs carbide chemistry and matrix precipitate stability, yet it has traditionally been selected empirically rather than from a predictive criterion linking M‐site choice to carbide chemistry, matrix alloying, and L12 stability; moreover, the reaction pathway ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT In laser‐directed energy deposition (LDED) of TiC/Ti6Al4V composites, a low content of micron‐sized TiC provides a good strengthening effect on hardness and strength, but the improvement in plasticity remains a challenge. By introducing synchronous ultrasonic impact treatment (UIT) into the LDED process, an ultrasonic‐assisted LDED (UA‐LDED ...
