Leaching of six elements–namely, Cu, Zn, Pb, Cd, Ni, and F from two semidry flue gas desulfurization ash samples and one waste gypsum sample collected from two different iron and steel plants and one power plant in Hebei, has been reported. Various extracting agents were used to conduct leaching experiments for desulfurization ashes. The dissolution of trace elements contained in the ashes were determined in order to estimate the possible impacts of the materials for stacking, back-filling or road-paving on the under-ground water and the environment and to assess the possibility of contamination of the sites by release of these ions. The alkalinity greatly determines the ion concentration in leaching liquids. It appears that the risk pollution of ground water as well as of surface water may not be avoidable if the ash alone is used for stacking et al. Nevertheless heavy metal contents of three samples in the leaching solution are far below the specified value regulated in ¿Identification standards for hazardous waste - Identification for extraction toxicity¿(GB5085.3-2007, in China).
报道了从河北省两家钢铁厂和一家电厂的两份半干法烟气脱硫灰分样品和一份废石膏样品中浸出Cu、Zn、Pb、Cd、Ni和F六种元素。采用不同的萃取剂对脱硫灰进行浸出试验。测定灰烬中所含微量元素的溶解,以估计堆放、回填或铺路材料对地下水和环境可能产生的影响,并评估这些离子释放对场地造成污染的可能性。碱度在很大程度上决定了浸出液中的离子浓度。看来,如果单独使用灰堆等,对地下水和地表水的污染风险是不可避免的。但浸出液中三个样品的重金属含量远低于《危险废物鉴定标准-萃取毒性鉴定》(GB5085.3-2007)规定的规定值。

An extracellular biopolymer (PS-2) produced by Pseudomonas fluorescence C-2 was used as an alternative biosorbent to remove toxic Pb(II) metallic ions from aqueous solutions. The prepared biosorbent PS-2 were characterized by FTIR and SEM. The effect of experimental parameters such as pH, dosage of biosorbent , Pb(II) initial concentration and contact time on the adsorption was studied. It was found that pH played a major role in the adsorption process, the optimum pH for the removal of Pb(II) was 6.0. SEM images showed that the surfaces of particles was rough and irregular with large area for metal-surface interaction, the FTIR spectra showed carboxyl , hydroxyl and amino groups of the PS-2 were involved in chemical interaction with the Pb(II) ions. Equilibrium studies showed that Pb(II) adsorption data followed Langmuir model. The maximum adsorption capacity (qmax) for Pb(II) ions was estimated to be 94.58 mg/g. The kinetic studies showed that the kinetic rates were best fitted to the pseudo-second-order model. The study suggestted that the novel extracellular biopolymer biosorbent have potential applications for removing Pb(II) from wastewater.

A new AC-DC-AC matrix converter topology based on Cuk is proposed. The basic configuration of the new topology and its fundamental principle are firstly introduced, the analytic expression on the function of voltage transfer ratio and duty cycle is analyzed, and the rationale of double-loop control strategy is clarified. Finally the validity and feasibility of the new topology are tested by means of computer simulation and prototype experiment. The results indicate that the regulation of the voltage transfer ratio and of the output frequency can be adequately implemented by these new converters with low harmonic distortions of waveform. This study suggests that the problem of low voltage transfer ratio, which has been an inherent drawback of the traditional MCs, can be effectively overcome, and the approach may provide inspiration for further engineering application.

An experimental research on hydrogen sulfide removal by DBD was carried out. This study explored the influences of initial concentration ,gas flow rate, applied voltage and frequency on hydrogen sulfide removal. In addition, the differences among the no packing and ceramic raschig-ring packing in the reactor were discussed. Meanwhile, during plasma processing to decompose hydrogen sulfide, SIE was analyzed using the Q–V Lissajous diagram. The experiment data suggested that hydrogen sulfide removal efficiency raised with the addition of the applied voltage, frequency and the reducing of the initial concentration of hydrogen sulfide and gas flow; it was found that under the following conditions: applied voltage 19 kV, frequency 300 Hz, gas flow rate 8 L/min, inlet gas concentration of hydrogen sulfide 30.1 mg/m3, the hydrogen sulfide removal reached the maximum of 100%. In the presence of the packing, hydrogen sulfide removal efficiency was higher than in the case of no packing, 93.26% for the former reactor and 69.29% for the latter.

The objective of this study is to assess the environmentaly friendly Ni(II) adsorption from synthetic wastewater using extracellular biopolymer(PS-2) produced by Pseudomonas fluorescence C-2. The ability of PS-2 to remove the Ni(II) ions was investigated by using batch biosorption procedure. The effects such as pH, dosage of biosorbent, Ni(II) initial concentration and sorbate–sorbent contact time and agitating speed on the adsorption capacities of PS-2 were studied. Biosorption equilibriums were rapidly established in about 60 min and the adsorption kinetics followed the pseudo-second order kinetic model. The maximum Ni(II) adsorption capacity determined from Langmuir isotherm were 80.50 mg /g PS-2 at pH 5.0 ,at 25±2 ¿C and shaker speed 150 rpm, respectively. The carboxyl , hydroxyl and amino groups of the PS-2 were involved in chemical interaction with the Ni(II) ions depicted by scanning electron microscopic (SEM) and Fourier transform infrared spectroscopic (FTIR) results. The study points to the potential of new use of extracellular biopolymer PS-2 as an effective biosorbent for the removal of Ni (II) and from environmental and industrial wastewater.

This paper describes the dissolving process of recycling waste batteries through synthesizing Mn-Zn ferrite by using mixed acid and water as leaching solution and oxalic acid as reductant. Some factors were investigated that include the proportion of mixed acid and its dosage, liquid-solid ratio, dosage of reductant time and temperature. Results show that an excellent dissolving effectiveness was gotten when the leaching solution composed of mixed acid (HNO3/HCl=1:3-1:4 V/V) which was 0-20% in excess and oxalic acid which was 10-20% in excess at a condition that the temperature was under 40¿, liquid/solid ratio was about 4.6, the time for first leaching step was longer than 10h and second leaching step was 1 hour. The recovery ratios of Mn, Zn, Fe, Ni, Cu and Hg were about 99%, even up to 100%, and the residue had a very low mercury content level.
本文介绍了以混合酸和水为浸出液,草酸为还原剂,回收废电池合成锰锌铁氧体的溶解工艺。考察了混合酸的配比及用量、液固比、还原剂用量、时间和温度等因素。结果表明:混合酸(HNO3/HCl=1:3-1:4 V/V)过量0 ~ 20%,草酸过量10 ~ 20%,在温度低于40℃,液固比约为4.6,第一步浸出时间大于10h,第二步浸出时间为1 h的条件下,浸出效果良好。Mn、Zn、Fe、Ni、Cu、Hg的回收率均在99%左右,甚至可达100%,残渣中汞含量极低。

On the base of expatiation the background of hydrogeology in Hengshui area, the chemical character of the shallow salt water is explained by the classification methods such as Shoka Lev and SuLin according to the data of samples in the paper. We have discussed the genesis mechanism by using cluster analysis, factor analysis, hydro-geochemical parameters and geologic interpretation. It reaches conclusions that the types of water chemistry and its causes are complex in the research area; the shallow salt groundwater is the results of three types: affection of mainland salinity, seawater intrusion and human affection. The paper a view of the development and technical methods of utilizing shallow groundwater and make the contour map of the ratio between salt and fresh water with the test of samples. It can guide the agricultural production and has important practical significance.
本文在阐述衡水地区水文地质背景的基础上,根据样品资料,采用Shoka Lev和SuLin等分类方法对浅层咸水的化学特征进行了说明。通过聚类分析、因子分析、水文地球化学参数和地质解释等方法探讨了其成因机制。结果表明:研究区水化学类型及其成因较为复杂;浅层含盐地下水是陆地盐度影响、海水入侵影响和人为影响三种类型的结果。本文对利用浅层地下水的发展和技术方法进行了展望,并通过样品试验绘制了盐淡水比等高线图。它可以指导农业生产,具有重要的现实意义。
