浸没式膜混凝吸附反应器处理北江水的试验研究

采用浸没式膜混凝反应器(MCR)和浸没式膜混凝吸附反应器(MCAR)处理北江流域地表水,考察了两种工艺对污染物的去除效果及膜污染情况。结果表明,MCR与MCAR的出水浊度均低于0.100 NTU;随着混凝剂投加量的增加,MCR对有机物的去除效果逐渐提高,跨膜压差(TMP)的增加速率逐渐降低;在相同混凝剂投加量条件下,MCAR对有机物的去除效果优于MCR,且膜污染程度会进一步减缓。     

焦化废水曝气生物滤池深度处理试验研究

研究了氧化剂（H2O2）投加量对焦化废水曝气生物滤池深度处理效果的影响,同时考察了气水比、回流比对系统深度处理焦化废水的影响,研究得出：最佳氧化剂投加量（以H2O2／CODcr质量比计）、最佳气水比、最佳回流比分别为3：1,（2-3）：1,0．5：1,此时有机污染物（CODcr）、氨氮（NH3-N）平均总去除率分别为49．35％,91．32％,并且运行稳定可靠。     

The adsorption of various pollutants from aqueous solutions on to activated carbon

The ability of activated carbon. Filtrasorb 400, to adsorb various pollutants from aqueous solutions has been studied. The pollutants investigated are phenol, p-chlorophenol, sodium dodecyl sulphate, mercuric ions and chromic(III) ions. The saturation adsorption capacity of the activated carbon for the pollutants is 213, 434, 361, 35 and 138 mg g^?1 for phenol, p-chlorophenol, sodium dodecylsulphate, chromium(III) and mercuric(II) respectively. Equilibrium isotherm analyses were undertaken using Langmuir and Freundlich equations.
