Study on System of Microbial Hydrogen Production [PDF]
, 2005 利用微生物将自然界中极为丰富的生物质降解为糖类物质，再转化为氢或乙醇等能源物质，对缓解人类目前所面临的能源危机，降低环境污染，实现经济的可持续发展战略等有重要的意义.本研究利用纤维素降解菌株灰绿曲霉（Aspergillusglaucus）XC9将秸秆（稻草粉）降解成糖类物质，并利用产氢微生物产酸克雷伯氏菌（Klebsiellaoxytoca）HP1，将其转化成氢，实现秸秆的综合利用；以曲霉所形成的菌丝球吸附并固定产氢细菌进行连续流产氢，建立了一种适用于连续流制氢过程中产氢细菌截留的新方法 ...

秸秆碳和硫酸铝对富营养化水体中氮磷的吸收去除效应及其影响因素
Shuitu Baochi Xuebao, 2011 为解决中国水体富营养化问题,将秸秆碳与硫酸铝作为一种有效吸附水体中总氮、总磷的吸附剂,通过室内模拟试验,采用平衡吸附法,考察了秸秆碳和硫酸铝投加量、pH值、振荡时间、温度、扰动、秸秆碳粒径等不同环境因素条件下对吸附效果的影响。结果表明:在秸秆碳和硫酸铝投加量为0.2 mg/L、振荡时间为120 min的条件下,吸附效果最好,去除率可达80%以上。通过对各因素与秸秆碳、硫酸铝对总氮和总磷的吸附效果分析得知,加入适量的秸秆碳和硫酸铝,可以降低水体中总氮、总磷的含量,吸附效果对温度、振荡时间、pH值变化敏感 ...
