Gongye shui chuli, 2016 煤气化废水是煤气化过程中产生的废水，具有污染物浓度高、有毒、难降解等水质特点。从高浓度煤气化废水处理工艺的物化预处理、生化处理和深度处理三个环节介绍了煤气化废水处理技术的研究现状，并着重分析各处理技术的优缺点和在应用中存在的问题。展望了煤气化废水处理技术的未来研究方向，即脱酚和蒸氨工艺的优化、膜生物反应器强化工艺及膜技术深度处理的进一步研究，为解决煤气化废水治理难题提供借鉴和参考。

Integrative Conservation, Volume 4, Issue 3, Page 405-415, September 2025.Assessing the genetic diversity of edible insects harvested from the wild is a pre‐requisite for designing conservation and management policies. The caterpillars of Gynanisa maja (Saturniidae) are harvested in large numbers in mopane woodlands in southern Africa, where they represent a seasonal source of income and nutrition to many rural communities ...

Shuitu Baochi Xuebao, 2021 主要通过土柱模拟试验探究不同有机物料对渗滤液的盐分和可溶性有机碳（DOC）以及不同深度土壤盐分、有机质和微生物生物量碳氮的影响，设置有机硅功能肥（WO）、颗粒状有机物料（YP）、粉末状有机物料（GG）、颗粒状有机物料和粉末状有机物料各50%（YG）以及不添加有机物料（CK）共5个处理。结果表明，有机物料的添加提高了渗滤液的EC值及水溶性Ca2+、Mg2+和Na+含量，YP处理的渗滤液盐基离子含量最高，而WO处理的渗滤液中DOC含量最低；与CK处理相比，WO处理显著提高各深度土层的水溶性Ca2+、Mg2 ...

The Two Faces of Introgression in Conservation Biology 基因渗入在保育生物学中的双重面貌
Integrative Conservation, Volume 4, Issue 3, Page 339-344, September 2025.Conservation biologist need to take into account the various aspects of introgression in their attempts to protect the species integrity and evolutionary potential of threatened species. To do so, they have to overcome the bias created by the Mayrian species concept that considers species as having distinct gene pools.

曝气生物滤池—臭氧氧化—曝气生物滤池组合工艺对印染废水的深度处理
Gongye shui chuli, 2009 采用曝气生物滤池(BAF)—臭氧氧化—曝气生物滤池三段组合工艺对二级生化后的印染废水进行深度处理,进水COD为90～150mg/L,色度为16～32倍,经该工艺处理后的出水COD35mg/L,去除率75%,色度降到4倍以下。工程运行实践表明,该深度处理系统运行稳定,处理效率高,出水水质达到印染场洗水工序对水质的要求。
