污水处理多级AO工艺配水比例算法的改进

针对传统分段多级AO工艺算法的弊端,对传统计算方法中基于边界条件假定进行推导计算所存在的问题进行分析,提出一种通过试算方式确定分段数及各段比例的计算方法并在污水处理厂调试中进行实践验证,最终出水水质能够较为稳定的满足生产要求。

位山引黄灌区渠系配水模式

针对山东位山灌区引黄水源不足的实际,作为位山引黄灌区渠系优化配水决策支持系统的一个组成部分,为满足科学配水的需要,创新性地进行了蓄水期配水、顺序配水、差额比例配水和均衡比例配水4种配水模式设计,并对其适用条件进行了比较,并分别给出了应用实例,可根据不同情况分别选用。为科学调度水资源,实现按方收费提供了有效保证。

Control core of safety management: the reasonable distribution of safety resources

The distribution of resources is the basis of safety management.Based on thesystematic analysis of a resource distribution system affecting the level of safety,the bestdistribution proportion between safety activities and production and best resources distributionproportion among the various links of security activities are presented.Moreover,itis stated that the distribution of resources law needs to be researched deeply in practicalwork to achieve optimization of safety management practice.
