生物法净化废气中低浓度挥发性有机物的过程机理研究

 针对生物法净化低浓度挥发性有机废气的过程机理研究表明，生物膜填料塔净化低浓度甲苯气体是一个以气膜控制为主的传质过程，其中甲苯的生化降解属于瞬时快速化学反应，即甲苯的生化降解反应速率远远超过甲苯在液膜中的扩散速率，甲苯的生化降解在气液相界面处即可发生，其宏观表现即为甲苯气体直接吸附在润湿的生物膜上后迅速被微生物生化降解。因此，可以从气体吸附理论的新角度去解释生物法净化废气中低浓度挥发性有机物的动力学过程。对于低浓度挥发性有机废气的生物法净化装置的设计与操作而言，凡能改善传质条件、减少气膜阻力的措施均能强化这一生物吸收净化过程。

Emergency centers in Israel: A small community organizes to cope with war related crises*

This paper focuses on community-wide emergencies caused by war-related events in Lebanon at the beginning of June 1982. Mobilization for the "Peace for Galilee" campaign began on Friday, 4th June. Overnight, families were disrupted, husbands and sons were in danger, and within 24 hours there were notifications of casualities and deaths. Families in crisis became a widespread phenomenon. In Herzlia, as in many other communities, a new service - the Emergency Center - emerged under the auspices of the Ministry of Labor and Social Affairs and the Municipality. The authors describe this process of getting organized, the populations served, how the Center was staffed, the role of citizen volunteers, and the types of interventions used to help vulnerable families as well as soldiers home on leave. Stress is placed on the unique type of short-term co-operation achieved between social workers of the local Department of Social Welfare, the staff of the Department of Community Services (especially its Volunteer Bureau), the local liason officer of the Israel Defence Force, the municipal government, and public-spirited volunteers. Mention is made of conditions which made possible the activation of such a service within hours, of the Center's capacity to serve all segments of the population, and of how it was deactivated within a few weeks when the emergency ended. On the basis of lessons learned from this experience, the paper ends with a number of specific recommendations. The authors hope that such innovative forms of crisis-intervention will become part of the helping technology widely available at the community level in future years.
