大连声环境质量的灰色预测研究

根据1999年～2003年大连市区声环境质量的监测数据，采用两次残差修正GM（1，1）对2010年前声环境质量进行预测结果表明，修正后模型均为一级模型，进行中、短期预测精度高。预测结果可为城市噪声污染防治提供科学的依据。

Analysis of Roadside Inhalable Particulate Matter (PM10) in Major Korean Cities

A data analysis of three major Korean cities was conducted to assess roadside inhalable particulate matter 10 μm or smaller in aerodynamic diameter (PM₁₀), including temporal and meteorological variations, over a recent period of 4 to 6 years. The yearly roadside PM₁₀ concentrations presented a well-defined increasing trend or no trend depending on the roadside monitoring station. Most mean values exceeded or approximated the Korean standard of 70 μg/m³ per year for PM₁₀. A representative roadside diurnal trend was characterized by a distinct morning maximum. In most cases, the Sunday roadside concentrations were similar to or somewhat lower than the weekday concentrations, and the PM₁₀ concentrations presented a well-defined seasonal variation, with the maximum concentration in March. The monthly maximum concentrations observed in March were most likely attributable to Asian dust storms. In two metropolitan cities (Seoul and Busan), the frequency of days with roadside PM₁₀ concentrations exceeding the standard of 150μg/m³ per 24 h was much lower for the roadside monitoring stations than for the residential monitoring station, whereas in the third city (Daegu), this result was reversed. Interestingly, the average maximum concentrations observed for the roadside sites in Seoul and Busan during March were higher than those for the residential sites, suggesting that the roadside concentrations responded more to the dust storms than the residential areas. The relationship between the pollutant concentrations and five important meteorological parameters (solar radiation, wind speed, air temperature, relative humidity, and precipitation) showed that the number and type of meteorological variables included in the equations varied according to the monitoring station or season. Finally, the current results confirmed that attention should be given to the PM₁₀ exposure of residents living near roadways.     

基于GIS的上海市嘉定区暴雨积涝灾害风险区划研究

根据2006-2012年上海嘉定区9个气象站点的小时降水资料,结合嘉定区的社会经济与自然地理要素,构建一个集致灾因子、孕灾环境、承灾体及防灾减灾能力为一体的区域暴雨积涝风险评价模型。通过GIS技术实现各指标的栅格化,并利用指数模型对各因子基于500 m×500 m栅格的基本单元进行计算,编制嘉定区的暴雨积涝灾害风险区划图,构成嘉定区五个等级的风险,分别为高、次高、中等、次低和低。区划结果表明嘉定区的暴雨积涝灾害危险性指数从中心向外围成递减的趋势,且嘉定镇、新城和工业南区相对风险较高,华亭、徐行、南航和江桥风险相对较低。经嘉定区历年暴雨积涝灾情资料、典型暴雨积涝案例和专家的验证,均表明风险区划的结果和实际灾情符合度较高,对嘉定暴雨积涝的防灾减灾具有重要的现实指导意义。     

用于青霉素废水处理的高效菌株的分离及特性研究

从某制药厂污水处理站的活性污泥中筛选出两株能以青霉素废水中有机物为惟一碳源和能源的高效降解菌k1和k2。通过形态及生理生化特征分析,初步鉴定2株菌为芽孢菌,其中k2为短小芽孢杆菌（bacillus pumilus）。2株菌的最适pH值分别为8和7,温度均为35℃,当废水含量50%时,菌株k1和k2对青霉素废水的COD去除率分别为79%和81%。单菌株与混合菌株对废水的降解特性试验表明,前48 h混菌对废水的去除率不及单菌株,而48 h后混合菌株去除率高于单菌株,60 h时达到最高为85%。     

3株反硝化聚磷菌的分离与鉴定

通过烛缸法培养富集、分离,结合除磷试验、硝酸盐还原产气试验及异染颗粒和PHB颗粒染色辅助检验相结合的方法筛选,得到3株具有较高脱氮除磷效率的反硝化聚磷菌DNPA8, DNPA9和DNPA10。在富氮富磷培养基中培养48 h,各菌株的脱氮率均大于75%,除磷率均大于78%。采用多相分类的方法确定了3株反硝化聚磷菌的分类地位,DNPA8为嗜麦芽寡养单胞菌,DNPA9为水生丛毛单胞菌属首次发现的反硝化聚磷菌;DNPA10为约翰逊氏不动杆菌。该研究结果为富营养化水体的治理提供了有效的菌种资源。
