Treatment of black liquor from the papermaking industry by acidification and reuse

Two different kinds of black liquor from the papermaking industry were treated by acidification and reuse. The experimental parameters and conditions were discussed in detail. The experimental results indicated that the treatment process mentioned in this article is an effective process for the treatment of black liquor from the papermaking industry. By the treatment, the solid materials in black liquor are transferred into two by-products and the other components are reused or evaporated. Thus, no wastewater except some condensation water would be discharged in pulping process and the problem of oollution of black liauor would be effectively solved.     

云南临沧矿产品开发中的放射性污染

临沧是我国铀矿资源地之一，本文在对当地多年的放射性矿及伴生放射性矿产产品开发中放射性污染问题进行了分析研究后，对目前采取的一些防治和管理措施进行了综合评价，对同类地区进行放射性污染管理具有借鉴作用。     

染化废水厌氧生物处理技术的研究

鉴于厌氧微生物对偶氮染料的还原裂解作用，开发了以易降解工业有机废水作为外加碳源的染化废水厌氧生物处理的新技术．试验结果表明：在进水ＣＯＤ３１００—３５００ｍｇ／Ｌ，ＣＯＤ总／ＣＯＤ染化比值４０，ＨＲＴ３．０ｄ下，ＣＯＤ去除率＞８０％，最低染化ＣＯＤ去除率＞４５％，色度去除率＞８５％；实验证实，在厌氧处理过程中，染料组分的结构已发生了明显的变化；反应器内的污泥大多呈颗粒状；污泥活性和工艺性能可控制工艺运行参数得以维持．     

单甲脒农药的微生物降解代谢研究

研究了门多萨假单胞菌ＤＲ－８菌株对单甲脒农药的降解代谢。该菌利用率甲脒作为生长的唯一氮源，其对单甲脒的呼吸作用试验确证了该农药的生物可降解性。单甲脒对细菌生物氧化代谢关联酶活性的影响研究表明，脱氢酶对单甲脒较敏感，而ＮＡＤＨ氧化酶则耐受性较强。

价格体制改革中的环境政策调控

以价格体制改革为主线，着重分析和评价价格体制改革给环境保护工作带来的积极效应和负面影响。依据经济体制改革的客观要求，提出进一步利用价格杠杆加强环境保护工作的措施与方法。     

Study on nitrile-degrading microorganisms

Two strains of bacteria were isolated from nitrile polluted soils, and identified as Corynebacterium boffmanii and Arthrobacter flavescens. Acetonitrile, propionitrile, butyronitrile and acrylonitrile were degraded by these bacteria to yield corresponding amides, carboxylic acids and ammonia. The nitrile-degrading abilities of these strains were investigated. The removal rates for the nitrile were nearly 100%, after these bacteria were grown in medium containing 10000 ppm of aceto-, propio-, or butyronitrile at 28 ℃ for 24h. When the reaction mkture consisting of 5000 ppm of above mentioned nitriles or acrylonitrile and 20g (dry cell) /L resting cells of the two strains in 0.06mol/L phosphate buffer (pH7.5) was incubated separately at 25 ℃ with moderate shaking for 15 or 45 min, the nitrile could be degraded completely. The optimum growth conditions for C.hoffmanii and A.flavescens were studied as well.     

广西南部三叠纪强过铝质火成岩岩石化学特征的动力学意义

为深化对广西南部地区印支期造山运动深部动力学机制的理解,采用该地区三叠纪强过铝质火成岩的岩石化学数据提取其源区熔融温度以及成分特征方面的信息。结果显示:广西南部三叠纪强过铝质火成岩属于高钾钙碱性系列,形成于印支期后碰撞构造背景中。它们的Al2O3/TiO2小于100,CaO/Na2O多数大于0 3、少数小于0 3。同时,这些强过铝质火成岩的Al2O3/TiO2与其SiO2含量有正相关趋势,而CaO/Na2O与SiO2含量呈明显的负相关关系。这些岩石化学特征表明,强过铝质火成岩部分源于泥质岩的部分熔融,部分源于砂岩或正变质岩的部分熔融,但不排除后者可能是泥质岩部分熔融产物和玄武质岩浆相混合的结果;同时这些强过铝质火成岩形成源区的温度高(>=875℃)。因此,广西南部三叠纪时期的深部能量来自以底侵玄武岩浆加热作用所体现出来的软流圈地幔的平流热传递过程。
