永梅会与中下扬子地区的成矿条件对比

永海会地区的区域构造、含矿地层和建造、中生代火山侵入岩体特征、局部控矿构造以及成矿物质来源、硫氢氧同位素、铅同位素、年龄同位素等成矿信息，都与扬子区、萍乐区已知铜金矿集区有许多相似之处。通过对比表明，永海会地区具有极大的找矿前应景。     

草履虫──针杆藻群落对混合印染废水净化作用的条件实验

本文对混合印染废水的静态净化过程，进行了生物群落观察和条件实验。发现废水净化初期以大量细菌和草履虫（以 Ｐ． Ｃａｕｄａｔｕｍ为主）繁殖为特征，同时伴生着少量浮游藻类。随着净化过程的进行，细菌和草履虫数量下降，以针杆藻（以 Ｓ． ａｕｃｓ为主）为建群种的浮游藻类群落占优势。化学分析表明，净化作用与温度、光照条件及废水起始浓度有关。     

环境税法律问题研究

在市场经济条件下，环境保护有必要更好地运用经济手段。环境税是一项重要的经济激励制度，但在我国仍是个新概念。探讨了环境税的概念特征、理论依据、税种和税制设计。     

循环经济国内外立法研究

二十世纪九十年代以来,由于传统线性经济带来的恶性结果,发展循环经济在国际社会上蔚为风潮.许多西方国家纷纷进行循环经济立法活动,德国和日本建立了较为完善的循环经济法律体系.从西方国家的立法经验我们可以看出,要发展循环经济,建立一个完善的法律保障体系至关重要.我国的循环经济立法还处在初级阶段,要吸收和借鉴先进经验,制定修改一批法律、法规,建立完善的循环经济法律体系,以促进循环经济发展.

Enhanced removal of high-As(Ⅲ) from Cl(-Ⅰ)-diluted SO4(-Ⅱ)-rich wastewater at pH 2.3 via mixed tooeleite and(Cl(-Ⅰ)-free) ferric arsenite hydroxychloride formation

An advanced cost-saving method of removal of high-As(Ⅲ) from SO₄(-Ⅱ)-rich metallurgi cal wastewater has been developed by diluting the SO₄(-Ⅱ) content with As(Ⅲ)-Cl(-Ⅰ)-rich metallurgical wastewater and then by the direct precipitation of As(Ⅲ) with Fe(Ⅲ) at pH2.3.As(Ⅲ) removal at various SO₄(-Ⅱ)/Cl(-Ⅰ) molar ratios and temperatures was investigated The results showed that 65.2–98.2%of As(III) immobilization into solids occurred at the SO₄(Ⅱ)/Cl(-Ⅰ) mo...     

Decomplexation of Cu-1-hydroxyethylidene-1,1-diphosphonic acid by a three-dimensional electrolysis system with activated biochar as particle electrodes

The feasibility of decomplexation removal of typical contaminants in electroplating wastewater, complexed Cu(II) with 1-hydroxyethylidene-1,1-diphosphonic acid (Cu-HEDP), was first performed by a three-dimensional electric reactor with activated biochar as particle electrodes. For the case of 50 mg/L Cu-HEDP, Cu(II) removal (90.7%) and PO initial pH 7, acid-treated almond shell biochar (AASB) addition 20 g/L, and reaction time 180 min, with second-order rate constants of 1.10 × 10⁻³ and 1.94 × 10⁻⁵ min⁻¹respectively. The growing chelating effect between Cu(II) and HEDP and the comprehensive actions of adsorptive accumulation, direct and indirect oxidation given by particle electrodes accounted for the enhanced removal of Cu-HEDP, even though the mineralization of HEDP was mainly dependent on anode oxidation. The performance attenuation of AASB particle electrodes was ascribed to the excessive consumption of oxygen-containing functionalities during the reaction, especially acidic carboxylic groups and quinones on particle electrodes, which decreased from 446.74 to 291.48 µmol/g, and 377.55 to 247.71 µmol/g, respectively. Based on the determination of adsorption behavior and indirect electrochemical oxidation mediated by in situ electrogenerated H₂O₂ and reactive oxygen species (e.g., •OH), a possible removal mechanism of Cu-HEDP by three-dimensional electrolysis was further proposed.     

事故出流时河流综合水质的计算机预测方法研究

河流上游的污水排放口或倒虹管等污水构筑因有可能发生事故出流而对下游的取水口存在着潜在的威胁，常规的单参数模型不能就事故出流对下游的影响作出公正评价。本文以QUAL－Ⅱ模型为骨架，以生动形象的动画形式演示出在整个排污过程中多个水质参数沿河道分布的变化全过程，并且，在模型中融入隶属度BP神经网络综合评价水质的模块，用它来对发生事故出流时下游取水口水域的水质变化进行综合评价，最后通过一个例子说明了该方法的优越性和合理性。
