微氧浓度对印染废水水解酸化效率及微生物代谢的影响

第32届中国气象学会年会

作者： Yuan Sun Zhong Zhong lan Yi Yao ha Yimei Sun College of Meteorology and Oceanography PLA University of Science and Technology Jiangsu Collaborative Innovation Center for Climate Change and School of Atmospheric Sciences Nanjing University National Climate Center Chinese Satellite Maritime Tracking and Control Department

A suite of semi-idealized numerical experiments are conducted to investigate the sensitivity of tropical cyclone(TC) intensity to changes of sea surface temperature(SST) over different radial extents. It is found that the increase of inner SST within the range 1.5–2.0 times the radius of maximum wind(RMW), defined as the effective radius(ER), contributes greatly to the increase of TC intensity and the reduction of TC inner-core size, whereas the increase of outer SST(defined as SST outside the ER)reduces TC intensity and increases TC inner-core size. Further analysis suggests that,the effects of SST inside and outside the ER on TC intensity rely on the factors that influence the TC *** the SST increases inside the ER, more surface enthalpy flux enters TC eyewall and less enters the outer spiral rainbands. This will decrease the RMW, leading to a smaller eyewall radius where strong latent heating is released. As a result, the central pressure of the TC deepens with stronger radial pressure gradient. Meanwhile,difference between SST and upper-tropospheric temperature increases. All above factors contribute to TC intensification as the inner SST increases. The opposite happen as the SST increases outside the ER. How TC intensity responds to the change of entire SST depends on the competitive and opposite effects of inner and outer ***, understanding the mechanisms is vital to the forecast of variations in TC intensity and inner-core size when a TC comes across an ocean cold or warm pool.

The adsorption of Cu（Ⅱ） from aqueous solution onto humic acid （ha） which was isolated from cattle manure （Cha）, peat （Pha）, and leaf litter （Lha） as a function of contact time, pH, ion strength, and initial concentration was studied using the batch method. X-ray absorption spectroscopy （XAS） was used to examine the coordination environment of the Cu（ll） adsorbed by ha at a molecular level. Moreover, the chemical compositions of the isolated ha were characterized by elemental analysis and solid-state 13C nuclear magnetic resonance spectroscopy （NMR）. The kinetic data showed that the adsorption equilibrium can be achieved within 8 h. The adsorption kinetics followed the pseudo-second-order equation. The adsorption isotherms could be well fitted by the langmuir model, and the maximum adsorption capacities of Cu（ll） on Cha, Pha, and Lha were 229.4,210.4, and 197.7 mg g-1, respectively. The adsorption of Cu（Ⅱ） on ha increased with the increase in pH from 2 to 7, and maintained a high level at pH〉7. The adsorption of Cu（Ⅱ） was also strongly influenced by the low ionic strength of 0.01 to 0.2 mol L-1 NaNO3, but was weakly influenced by high ionic strength of 0.4 to 1 mol L-1 NaNO3. The Cu（Ⅱ） adsorption on ha may be mainly attributed to ion exchange and surface complexation. XAS results revealed that the binding site and oxidation state of Cu adsorbed on ha surface did not change at the initial Cu（Ⅱ） concentrations of 15 to 40 mg L 1. For all the Cu（Ⅱ） adsorption samples, each Cu atom was surrounded by 40/N atoms at a bond distance of 1.95 A in the first coordination shell. The presence of the higher Cu coordination shells proved that Cu（Ⅱ） was adsorbed via an inner-sphere covalent bond onto the ha surface. Among the three ha samples, the adsorption capacity and affinity of Cha for Cu（Ⅱ） was the greatest, followed by that of Pha and Lha. All the three ha samples exhibited similar types of elemental and functional groups, but different contents of elemental and functional gr

In this study, we propose a data preprocessing algorithm called D-IMPACT inspired by the IMPACT clustering algorithm. D-IMPACT iteratively moves data points based on attraction and density to detect and remove noise and outliers, and separate clusters. Our experimental results on two-dimensional datasets and practical datasets show that this algorithm can produce new datasets such that the performance of the clustering algorithm is improved.

A 45-d laboratory experiment was conducted to compare the effect of four crop straws on the transformations of organic matter （OM） during composting of sewage sludge. The four crop straws included rape straw, wheat straw, maize straw and rice straw. The following parameters such as temperature, OM, humic-like substances （HS）, fulvic-like acids （FA） and humic-like acids （ha） were determined. The degradation of OM and the formation of HS and ha could be described well by the first-order kinetic model, while the FA content fluctuated during composting. The maximal degradation rates of OM in the compost piles added with rape straw, wheat straw, maize straw and rice straw were 34.7, 46.9, 54.7 and 52.8%, respectively, and the final contents of HS were 118, 128, 141 and 134 g kg-1, respectively, while the humification indices were higher in the compost piles added with maize straw and wheat straw than in those with rice straw and rape straw. The results indicate that a higher hemicellulose content and a lower C/N ratio in crop straw can result in a higher rate of OM degradation and higher contents of HS, while a higher content of lignin can lead to a higher polymerization degree of humic substances in compost piles. The final compost piles added with maize straw has the highest contents of OM, total nitrogen and humus substance as well as the highest values of polymerization degree, while compost piles with rape straw have the highest potassium content and those with rice straw have the highest pH values.

A biocathode with microbial catalyst in place of a noble metal was successfully developed for hydrogen evolution in a microbial electrolysis cell （MEC）. The strategy for fast biocathode cultivation was demonstrated. An exoelectrogenic reaction was initially extended with an H2-full atmosphere to enrich ha-utilizing bacteria in a MEC bioanode. This bioanode was then inversely polarized with an applied voltage in a half-cell to enrich the hydrogen-evolving biocathode. The electrocatalytic hydrogen evolution reaction （HER） kinetics of the biocathode MEC could be enhanced by increasing the bicarbonate buffer concentration from 0.05 mol·L-1 to 0.5 mol· L-1 and/or by decreasing the cathode potential from -0.9 V to - 1.3 V vs. a saturated calomel electrode （SCE）. Within the tested potential region in this study, the HER rate of the biocathode MEC was primarily influenced by the microbial catalytic capability. In addition, increasing bicarbonate concentration enhances the electric migration rate of proton carriers. As a consequence, more mass H＋ can be released to accelerate the biocathode-catalyzed HER rate. A hydrogen production rate of 8.44 m3. m 3. d1 with a current density of 951.6 A. m-3 was obtained using the biocathode MEC under a cathode potential of - 1.3 V vs. SCE and 0.4 mol· L-1 bicarbonate. This study provided information on the optimization of hydrogen production in biocathode MEC and expanded the practical applications thereof.
