Development and Application of Software Tools for Monitoring, Assessment and Reporting of Data Concerning the Operation of Urban Wastewater Treatment Plants in Cyprus

This work focuses on the development and application of appropriate software tools for recording, assessing and reporting data related to the operation of the Urban Wastewater Treatment Plants (UWTPs) in Cyprus. An appropriate Internet-Based Management System was designed, developed and installed at the premises of the UWTPs and of the Cypriot Competent Authority (Water Development Department — WDD) in order to coordinate and disseminate tasks and related information for monitoring the operation of UWTPs. In addition, a client Geographical Information System database was compiled to be used for obtaining and analyzing spatial information. The software tools are based on common procedures and state-of-the-art technology for the recording and transmission of data and information and they provide an integrated view related to the operation and the efficiency of wastewater treatment systems. Moreover, continuous control and systematic monitoring of the UWTPs by the operators as well as continuous and direct supervision of the UWTPs environmental performance is achieved by the personnel of the Competent Authority. Furthermore, direct and unobstructed provision of data to the Competent Authority of Cyprus is accomplished by the operators of the UWTPs, while the Competent Authority is supported to compose full and representative reports to the European Commission and other International Organizations. The developed tools enable the direct recording of data obtained through measurements and analyses, permit the comparison of data with existing legislation and provide an integrated picture of the operation of the wastewater treatment plants as well as the option to focus and assess each individual treatment stage.

基于B/S结构的分布式高职学生信息数据库管理系统

针对高职学生信息管理的现状,考虑到其系统数据收集的实时性要求不高,结合分布式数据库具有的物理分布性、逻辑整体性、站点自治性,适合在多种行业中应用等特点,本文提出了一种基于B／S结构的分布式高职学生信息数据库管理系统。该系统可以向高职学校学生工作者提供丰富、详尽的学生信息,实现学校内部包括各专业、班级的信息资源共享及不同用户权限的控制,具有较好的应用性和可扩展性。     

Alga-lysing bioreactor and the dominant bacteria strain

Alga-lysing bacteria have been paid much attention to in recent years. In this study, the alga-lysing strain P05 which was isolated from an immobilizing biosystem was immobilized by coke and elastic filler, forming two biological reactors. The removal efficiencies of algae, NH3-N and organic matter using the two reactors were studied. The results showed that strain P05 was an ideal algal-lysing bacteria strain because it was easy to be immobilized by coke and elastic filler which are of cheap, low biodegradability and the simple immobilization procedure. After 7 d filming, the biological film could be formed and the reactors were used to treat the eutrophic water. These two reactors were of stability and high effect with low cost and easy operation. The optimal hydraulic retention time (HRT) of each reactor was 4 h. The algae removal rates were 80.38% and 82.1% (in term of Chl-a) of coke reactor and filler reactor, respectively. And that of NH3-N were 52.3% and 52.7%. The removal rates of CODMn were 39.03% and 39.64%. The strain P05 was identified as Bacillus sp. by PCR amplification of the 16S rRNA gene, BLAST analysis, and comparison with sequences in the GenBank nucleotide database.

基于GIS的城市地震次生火灾仿真系统

地震次生火灾虽是1种相对罕见的城市灾害,然其巨大的破坏力却逐渐引起广大城市防灾工作者的注意。为了有效防止和抵御地震次生火灾,构建了基于GIS的城市地震次生火灾仿真系统,用于辅助防灾工作者预测和评价城市地震次生火灾的发生、蔓延、扑救和破坏过程。该仿真系统由4个部件构架而成,包括空间数据库、模型库、仿真中心和结果输出。空间数据库组织和收集城市中与地震次生火灾密切相关的空间和非空间数据,为仿真系统提供基础的数据源;模型库是整个仿真系统的核心,包括了地震次生火灾过程中3个关键阶段的模型,即震后起火模型、城市火灾蔓延模型和震后消防扑救模型;仿真中心是仿真系统的运行中心,实现数据和模型之间的集成,并提供完整的仿真方案进行模拟,并以表格、图件和报表的形式输出各种统计结果。这些统计结果可为防灾工作者的防灾决策提供科学的依据。
