污泥秸秆基活性炭的制备及其吸附性能分析

Gongye shui chuli
以脱水污泥和水稻秸秆为基底原料，采用热解-活化法制备了高品质的污泥秸秆活性炭，系统探讨了KOH活化剂与水稻秸秆添加量对活性炭成分、孔隙结构、表面形貌及特征官能团的影响，并探究了其对亚甲基蓝（MB）溶液的吸附性能和吸附动力学。结果表明，在干化污泥热解炭与KOH质量比为1∶1，干化污泥与水稻秸秆质量比为7∶3条件下制备的活性炭K73，具备最优的结构和吸附性能。K73的比表面积和孔容分别为1 122.0 m2/g和0.81 cm3/g，属于微孔-介孔复合结构。在初始MB质量浓度为400 mg/L ...

微波辐射对污泥浊度、沉降性和脱水性的影响

, 2012
将微波辐射应用于城市污水厂活性污泥脱水前的预处理,研究了微波辐射150 s内污泥浊度、沉降性和脱水性的变化,考察了自然沉降后上清液浊度、污泥沉降比(SV30)、离心后含水率和胞外聚合物(EPS)浓度的变化,并探讨了相关机理。结果表明,随辐射时间的增长,上清液浊度升高,而SV30和含水率均先减小后增大。在EPS质量浓度约120 mg/g的条件下,微波辐射处理前后的污泥含水率由84.32%降到了约76%

好氧颗粒污泥耐受高碳氮负荷的生物学机制研究

, 2013
在4 L反应器中，以好氧颗粒污泥为接种污泥，扩大培养了具有良好去除碳氮能力的好氧颗粒污泥。整个实验采用批次进水的方式运行，以补加葡萄糖和硫酸铵的猪场废水为基质，通过调节进水负荷、曝气量和沉降时间等条件，成功获得了成熟的好氧颗粒污泥。COD和NH4+-N去除率分别稳定在97%和85%左右。 　　首先，通过不断提高进水碳氮负荷，研究了好氧颗粒污泥同时耐受高碳氮负荷的能力。本实验培养出的好氧颗粒污泥呈黄褐色，近似椭球状，其表面凹凸不平，这种结构增加了好氧颗粒污泥的表面积。好氧颗粒污泥密度约为1.009g·ml-
