提高炼油污水处理场排水合格率的途径

为解决炼油厂外排污水存在的问题，该厂采取了一系列措施。如：改进污水处理工艺，应用新技术、新设备，加强上游管理，以减少冲击事故。通过这些努力污水场排水合格率连续几年一直达90％以上，污水回用率达30％以上。从1994年至今，污水处理场各套设备运行基本正常，达到了很好的处理效果。     

黑索金废水的处理

以球形活性炭为吸附剂，用吸附法处理黑索金（ＲＤＸ）废水，出水能够达到国家排放标准，球形活性炭的动态饱和吸附量为０．１２３－０．１４０ｇ／ｇ，吸附带长为２ｍ。吸附饱和的球形活性炭，可用碱液以复再生。笔者还提出了数学模型，导出了处理实验数据公式，此公式可推广应用于同类吸附实验数据处理。     

TOPHAZOP: a knowledge-based software tool for conducting HAZOP in a rapid, efficient yet inexpensive manner

Hazard and operability (HAZOP) studies constitute an essential step in the risk analysis of any chemical process industry and involve systematic identification of every conceivable abnormal process deviation, its causes and abnormal consequences. These authors have recently proposed optHAZOP as an alternative procedure for conducting HAZOP studies in a shorter span of time than taken by conventional HAZOP procedure, with greater accuracy and effectiveness [Khan, F. I. and Abassi, S. A., optHAZOP. An effective and efficient technique for hazard identification and assessment Journal of Loss Prevention in the Process Industries, 1997, 10, 191–204]. optHAZOP consists of several steps, the most crucial one requires use of a knowledge-based software tool which would significantly reduce the requirement of expert man-hours and speed up the work of the study team. TOPHAZOP (Tool for OPTmizing HAZOP) has been developed to fulfil this need.

The TOPHAZOP knowledge-base consists of two main branches: process-specific and general. The TOPHAZOP framework allows these two branches to interact during the analysis to address the process-specific aspects of HAZOP analysis while maintaining the generality of the system. The system is open-ended and modular in structure to make easy implementation and/or expansion of knowledge. The important features of TOPHAZOP and its performance on an industrial case study are described.     

用好氧-厌氧反复耦合固定床生物反应器处理肌苷生产废水

利用由多孔微生物载体构建的好氧-厌氧反复耦合固定床生物反应器进行了高浓度肌苷生产废水处理中试研究。连续84d的运行结果表明，当进水COD为1500-2700mg／L、水力停留时间为22．1h时，出水COD可维持在150mg／L左右，COD去除率达90％～95％。装置运行稳定后，未经沉淀的出水中的固体悬浮物质量浓度小于50mg／L，表明该反应器可避免剩余污泥的产生。中试结果验证了该反应器处理高浓度肌苷废水的可行性和优势，同时为装置放大提供了理论依据。

桥梁施工过程的布拉格光纤光栅安全监测技术

为了安全可靠地建好每座大跨桥梁,就要对每座桥的施工过程进行安全监测,传统的安全监测方法是采用电测技术,由于抗电磁干扰性差等原因,测试的数据真实性差。笔者在布拉格光纤光栅的传感原理、室内悬臂梁试验和埋设工艺的研究基础上,成功地在黑大公路牛头山大桥上布设了布拉格光纤光栅应变传感器,为对比布拉格光纤光栅的监测结果,埋设了应变砖测试混凝土的应变,监测了该桥预应力混凝土连续梁先简支后连续施工的全过程,施工监测结果表明:布拉格光纤光栅监测大桥施工结果准确、稳定和可靠,同时证明该光纤光栅测试技术可以用于桥梁施工过程的安全监测且结果明显好于传统的电测技术。

Calculating overpressure from BLEVE explosions

Although a certain number of authors have analyzed the prediction of boiling liquid expanding vapour explosion (BLEVE) and fireball effects, only very few of them have proposed methodologies for predicting the overpressure from such explosions. In this paper, the methods previously published are discussed and shown to introduce a significant overestimation due to the erroneous thermodynamic assumptions—ideal gas behaviour and isentropic vapour expansion—on which they are based (in fact, they give the maximum value of overpressure which can be caused by a BLEVE). A new approach is proposed, based on the—more realistic—assumption of an adiabatic and irreversible expansion process; the real properties of the substance involved in the explosion are used. The two methods are compared through the application to a given case.
