SRB的分离筛选及其去除废水中硫酸盐的响应面优化

open access: yesGongye shui chuli, 2020
从处理柠檬酸废水的IC反应器中的厌氧颗粒污泥中富集培养、分离筛选得到一株可以高效还原硫酸盐的菌株SRB-1,用以去除废水中的硫酸盐。在单因素实验的基础上,通过响应面法研究COD/SO42-(C/S比)、初始pH和Fe2+质量浓度三个因素的交互作用并确定去除废水中硫酸盐的最佳条件。结果表明,三个因素都显著影响了废水中硫酸盐的去除,其中C/S比影响最大,初始pH和Fe2+质量浓度交互作用较强;预测的硫酸盐去除最佳条件:pH为6.9、C/S比为4.4、Fe2+质量浓度为281.72 mg/L,此条件下SRB ...

硫酸盐还原─甲烷化两相厌氧工艺中的相分离

open access: yesGongye shui chuli, 1996
硫酸盐还原─甲烷化两相厌氧工艺中的相分离与一般意义上的相分离不同。废水中有硫酸盐存在时,由于硫酸盐还原作用的协助(包括解除酸化反应产物抑制和液相中游离硫化氢对产甲烷作用的抑制),顺利建立了两相。在第一相中进行酸化和硫酸盐还原,产甲烷菌不表现活性;在第二相中进行大部分的COD去除和产生与一般厌氧消化中质量相当的生物气。

含氨和硫酸盐废水的处理技术展望

open access: yesGongye shui chuli, 2012
目前许多废水不仅含有高浓度的氨氮,而且含有高浓度的硫酸盐,给废水治理带来难度。对同步脱硫反硝化工艺和硫酸盐型厌氧氨氧化工艺的研究进展进行了综述。同步脱硫反硝化工艺和硫酸盐型厌氧氨氧化工艺能同时脱氮和除硫,不仅无H2S排放,而且还具有节约碳源、污泥产量小和实现单质硫回收的优点。其中硫酸盐型厌氧氨氧化工艺无需曝气和有机物,具有更高的技术和经济优势,将是未来生物脱氮除硫技术的新方向。

Ce(IV)-RhB-盐酸吡硫醇化学发光体系的研究

open access: yes四川大学学报. 自然科学版, 2007
研究发现,在酸性介质中,Ce(IV)可以氧化盐酸吡硫醇产生较弱的化学发光,罗丹明B可以大大增强此发光,且增加的发光强度与盐酸吡硫醇的质量浓度在0.1~10 mg.L-1范围内呈良好的线性关系,由此建立了测定盐酸吡硫醇的流动注射化学发光新方法.对3 mg/L的盐酸吡硫醇连续平行测定11次,其相对标准偏差为2.8%,根据IUPAC建议,计算出该法的检出限为54μg/L(3σ).该法已成功测定了盐酸吡硫醇片剂和针剂中盐酸吡硫醇含量,结果令人满意.
