| 1 | The integration of methanogenesis with denitrification and anaerobic ammonium oxidation in an expanded granular sludge bed reactor显示文摘The integration of methanogenesis with denitrification and anaerobic ammonium oxidation(ANAMMOX) was studied in an expanded granular sludge bed(EGSB) reactor in this work. Experimental results from the continuous treatment of wastewater with nitrite and ammonium, which lasted for 107 days, demonstrated that wastewater with high nitrite and ammonium could be anaerobically treated in an expanded granular sludge bed reactor. More than 91% to 97% of COD were removed at up to about 3.9 g COD/(L·d) of COD volumetric loading rate. More than 97% to 100% of nitrite was denitrified at up to about 0.8 g NO -2-N/(L·d), which is 16 times higher than that in a conventional activated sludge system with nitrification/denitrification(0.05 gN/(L·d)). No dissimilatory reduction of nitrite to ammonium occurred in the process. However, maximum of about 40% ammonium was found to be lost. Batch tests of 15 days with sludge from the reactor showed that 100% of nitrite was denitrified completely, and about 3% of ammonium was removed when only ammonium (34.3 mg/L) and nitrite(34.3 mg/L) were added into the sludge suspension medium. Furthermore, about 15% of ammonium amounts were lost with organic COD addition. It suggested that the methanogenesis in the system could enhance ANAMMOX because of intermediate hydrogen produced during methanogenesis. | ZHANG Dai-jun 1,2 (1.

| 5 | A novel method for Co(Ⅱ) and Cu(Ⅱ) analysis by capillary electrophoresis with chemiluminescence detection显示文摘Based on the fact that some metal ions can catalyze the chemiluminescence(CL)reaction of luminol with K3Fe(CN)6,a novel capillary electrophoresis CL method was developed for the determination of Co(Ⅱ)and Cu(Ⅱ).The separation was carried out with a 10 mmol/L sodium acetate solution containing 0.8 mmol/L luminol and 2.0 mmol/Lα-HIBA(adjusted to pH 4.8 by HAc solution).The post-capillary reagent was 2.0 mmol/L K3Fe(CN)6 which was adjusted to pH 13.0 by NaOH solution.Under the optimum conditions,the detection limits(S/N=3)for Co(Ⅱ)and Cu(Ⅱ)were 7.5×10-11mol/L and 7.5×10-9mol/L,with the linear range of 7.5×10-9mol/L to 1.0×10-6mol/L and 7.5×10-8mol/L to 5.0×10-5mol/L, respectively. | Xiao Ming Guo~a Xiang Dong Xu~(a,b) Hui Jing Zhang~a Yong Gang Hu~(a,*) Jie Zhang~a a Institute of Environmental Science & Engineering,Huazhong University of Science and Technology,Wuhan 430074,China b Department of Chemistry,Huazhong University of Science and Technology,Wuhan 430074,China | 2007 | Chinese Chemical Letters2007，18，9： | 3 |

| 7 | Discrete large eddy simulation显示文摘Despite the intense effort expended towards obtaining a model for describing the turbulent flows of fluid, there is no model at hand that can do an adequate job. This leads us to look for a non-traditional approach to turbulence modeling. In this work we conjoin the notion of large eddy simulation with those of fuzzy sets and neural networks to describe a class of turbulent flows. In previous works we had discussed several issues concerning large eddy simulation such as filtering and averaging. Here, we discuss the use of fuzzy sets to improve the filtering procedure. | L.
