悬浮生物填料床-絮凝工艺处理亚硫酸盐制浆中段水研究     

张文浩  尚宏志  刘希文 《气象与环境学报》2007,23(5)

针对亚硫酸盐制浆造纸废液中段水可生化降解CODB与不可生化降解CODNB各半的水质特点,采用二级好氧悬浮生物填料浮动床处理及物化絮凝处理的工艺试验,取得了有关试验数据;并根据COD容积负荷与出水残留COD的关系,探讨了利用酶反应动力学曲线预测试验稳定运行状态下出水CODB值。结果表明:利用生化—絮凝两处理技术的优势互补,可使最终排水COD与BOD同时达到国家造纸工业水污染物排放标准。  相似文献

传统方法不能明确揭示泥河铁矿床多阶段热液叠加蚀变过程中元素迁移的继承性特征.运用等浓度图法(the isocon diagram),根据该区晚阶段蚀变都是叠加在稍早阶段蚀变之上的实际情况,采用早期蚀变岩石为原岩与稍晚期蚀变岩石的不活动元素拟合最佳等浓度方程,定量揭示主量元素在热液蚀变过程的迁移规律.研究表明,泥河铁矿床阳离子的沉淀顺序大致为:Na→Ca、Mg、Fe、P→Ca、Fe→Al、Si.从早到晚,元素的带入和带出是连续互补的,蚀变矿化作用是一个连续的过程.钠长石的大量出现是Na质沉淀的标志,代表铁矿化的开始;膏辉岩化是Ca、Mg、Fe质沉淀的表现形式,为磁铁矿体的近矿和容矿蚀变;次生石英岩化、高岭石化是早期迁移出的Al、Si质沉淀的结果,是磁铁矿化远程指示性蚀变.   相似文献

A study on hydrocarbon generation potential of deep source rocks and gas sources in Changling Fault Depression,Songliao Basin     

Ling Zan  Zhihuan Zhang  Jiajia Fei  Yuyuan Wu  Zhenying Zhang  Liming Qin  Ling Mei  Wenhao Li 《中国地球化学学报》2011,30(2):255-263

Through natural gas exploration in the Changling Fault Depression,abundant natural gas flows were obtained and high-quality source rocks were also reveiled.Based on bulk analyses,organic matter abundance,organic matter type and thermal maturity of the source rocks were studied systematically.At the same time,gas gener-ating intensity and gas generating quantity were quantitatively analyzed by using basin modeling technologies.The results indicated that gas source rocks of the Shahezi Formation are characterized by abundant organic matter and dark mudstone distributions and high-over thermal maturity.They possess high gas generating intensity with the biggest value surpassing 500×108 m3/km2,and large gas generating quantity,accounting from 74.40% of the total amount.The Yingcheng Formation has good gas-source rocks with moderate dark mudstone and relatively high organic matter.It has type-Ⅲ organic matter and low-over thermal maturity.The gas generating intensity is moderate,between 20×108 and 60×108 m3/km2.The gas generating quantity is 13.63% of the total amount.The Huoshiling Formation has relatively good source rocks with limited dark mudstone and low organic matter.It has type-Ⅲ kerogen and over-thermal maturity.The gas generating quantity is 7.10% of the total amount.The Denglouku Formation has poor-gas source rocks,and is characterized by undeveloped dark mudstone and low organic matter abundance.It has type-Ⅲ organic matter and low-high thermal maturity.Hydrocarbon gases in the Changling Fault Depression mainly originated from the Shahezi Formation,and secondarily from the Yingcheng Formation.The contribution of the Huoshiling Formation gas source rocks is relatively small.  相似文献
