A retrospective survey on the effect of Kaschin-Beck disease prophylaxis by a change of water sources

In order to provide further references for studing on the causes of Kaschin-Beck discase (KBD) and measuring for its prevention and treatment from a macroscopic view, we analyzed the natural growth and declineof KBD and the effects of selenium and humic acid on its occurrence from an epidemiologic angle. In this article through a retrospective survey on the spots of disease areas by comparison between a change in water sources and that without. It was proved that a change in water sources was an effective measure for the prevention of KBD occurrence, and the pathogenic factor of KBD was one (or several kinds) of organic compounds or active radicals related to water.

膨润土对Pb^2＋、Cu^2＋、Cr^3＋的吸附动力学及等温线研究

研究所用膨润土的主要成分为SiO2和Al2O3，属于Ca基膨润土，BET表面积为50．83m^2／g。在恒温及恒定pH条件下，用静态吸附法研究了膨润土对Pb^2＋、Cu^2＋、Cr^3＋的吸附特性，结果表明其较好地符合Lagergren二级吸附速率方程，对这3种离子的吸附速率为Pb^2＋〉Cu^2＋〉Cr^3＋。利用3种等温线方程对吸附过程进行拟合，发现利用Langmuir吸附等温方程计算的值与膨润土吸附Pb^2＋、Cu^2＋、Cr^3＋试验数据最为吻合。膨润土对3种金属离子的平衡吸附量为Cr^3＋〉Cu^2＋〉Pb^2＋。     

漓江流域红壤侵蚀区植被演替与复合农林试验

漓江季节性的干旱和洪涝并存成为地方政府、有关专家和旅游行业密切关注的环境问题,漓江流域的环境建设尤其是上游森林植被恢复,成为生态治理重点内容。漓江上游红壤区植被类型主要包括针叶林、阔叶林、竹林、灌丛和草丛,植被的水分特征差异较大,植被的生态调节、水源涵养功能各异。在漓江上游红壤区开展4种模式的植被恢复和复合农林试验示范,3年的试验表明,乡土常绿阔叶树适应性强、有效保持水土,果林经济效益显著、但生态功能较差,木本药材林具有较好的生态功能和潜在的经济效益。通过调查和试验示范,提出亚热带红壤退化山地农林经营的植物种类和复合模式,对漓江流域水资源调控和水土流失治理提出建议和对策。     

Effect of calcium formate as an additive on desulfurization in power plants

SO_2 in flue gas needs to be eliminated to alleviate air pollution. As the quality of coal decreases and environmental standard requirements become more stringent, the highefficiency desulfurization of flue gas faces more and more challenges. As an economical and environmentally friendly solution, the effect of calcium formate as an additive on desulfurization efficiency in the wet flue gas desulfurization(WFGD) process was studied for the first time. Improvement of the desulfurization efficiency was achieved with limited change in p H after calcium formate was added into the reactor, and it was found to work better than other additives tested. The positive effects were further verified in a power plant, which showed that adding calcium formate could promote the dissolution of calcium carbonate, accelerate the growth of gypsum crystals and improve the efficiency of desulfurization. Thus, calcium formate was proved to be an effective additive and can potentially be used to reduce the amount of limestone slurry required, as well as the energy consumption and operating costs in industrial desulfurization.
