People and Nature, Volume 7, Issue 7, Page 1749-1768, July 2025.Abstract Social‐ecological systems (SES) are coupled systems formed by the intricate interactions between humans and nature. Our movement towards sustainable lifestyles requires a robust understanding of these interactions. Achieving a sustainable win‐win situation for both social and ecological systems, therefore, necessitates a sound scientific ...

Gongye shui chuli, 2007 以三氯化铝和有机高分子PGA为原料,制备了复合絮凝剂CPAC,并探讨了该种絮凝剂对模拟染料废水的脱色作用。研究表明,在同等铝盐投量的情况下,相对于PAC而言,CPAC脱色效率明显提高,且脱色率随PGA与铝盐的质量比(O/A)增高而上升。以活性艳红K-2BP染料为例,铝盐投加质量浓度6.8mg/L时,PAC脱色率75.5%,CPAC(O/A=0.05)脱色率为81%,CPAC(O/A=0.1)脱色率为86%。3种染料中,CPAC对分散黄G的脱色效果最好,铝盐投加质量浓度为3.3mg/L时脱色率达98%。

Gongye shui chuli, 2020 以复杂染料废水为研究对象，从活性污泥中筛选出高效脱色菌株，经鉴定为路德维希氏肠杆菌株，编号N1。研究了温度、pH、NaCl浓度等因素对菌株N1脱色效果的影响。结果表明，随着pH和温度的增加，菌株N1对复杂染料废水的脱色率均呈先升高后降低的趋势，温度为35℃、pH为7时其脱色率分别可达91.2%、93%。增大NaCl浓度，菌株N1的脱色能力降低，盐度为10 g/L时其脱色率仅为28%。紫外和GC-MS分析表明发色基团—C═O和—N═N—消失，出现苯酚和芳香胺类物质。
