Questa è una mini opera filosofico-scientifica che unisce riflessione e descrizione per esplorare l’origine, l’evoluzione e il destino dell’universo. Nasce dal desiderio di coniugare la profondità lirica della filosofia con la concretezza descrittiva della fisica, proponendo una nuova visione: l’universo non come frutto di perfezione, ma come ...

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。

Gongye shui chuli, 2007 以Ce4+为氧化剂对酸性黑10B水溶性染料模拟废水进行脱色处理,研究了各种反应条件对脱色率的影响,并且对脱色反应机理进行了分析。结果表明:在染料的初始质量浓度为10 mg/L,pH=1,Ce( SO4) 2·4H2O投加量为80 mg/L,紫外灯光照,反应时间为120 min的条件下,脱色率可达到97%。说明以Ce4+为氧化剂对酸性黑10B水溶性染料具有很好的脱色效果,且脱色速率快,药品用量少,成本低,安全无毒,在废水处理上有较大的应用前景。此外,研究发现:紫外灯照射可大大提高脱色速率,缩短脱色时间。

Gongye shui chuli, 2007 石狮宏山五堡印染废水处理厂排放水中含难生物降解和絮凝的活性艳红X-3B,对其进行了脱色实验。对比了焦炭阴极床电还原法、NaClO氧化法、铁屑床还原法3种脱色工艺。结果表明,在实验条件下,焦炭阴极床电还原法脱色效果较稳定,脱色后印染废水色度可达到排放标准,具备工业推广价值;NaClO氧化法脱色效果不理想;铁屑床还原法可以有效脱色但失活快,修复难。

不同脱色剂对油脂中叶绿素脱除的影响Influence of different decolorants on chlorophyll removal from oils
Zhongguo youzhi为筛选高效脱除叶绿素的脱色剂，为油脂工业生产中脱色剂的精准使用提供参考，以大豆油和菜籽油为例，采用不同种类脱色剂进行脱色，分析脱色剂参数（比表面积、介孔面积、孔道结构）对叶绿素脱除效果的影响。结果表明：3种主要的矿物类脱色剂对叶绿素的脱除能力强弱为活性白土>凹凸棒土>膨润土，活性白土对叶绿素的脱除效果与其比表面积或介孔面积呈正相关关系；活性炭对叶绿素的脱除效果与其比表面积没有明确的相关性，但与其介孔面积呈正相关关系，当活性炭介孔面积从3.8 m2/g提升至275.4 m2/g时，叶绿素脱除率提升了140.
