1高校集中浴室废水回收利用研究显示文摘分析了青岛某高校浴室存在的问题及废水排放特点。采用水源热泵技术对洗浴废水中的低品位热量进行回收。采用比较成熟的废水处理技术,将其中的污染物进行处理,使之符合杂用水水质标准,可用于冲厕、绿化、道路喷洒等。项目改造完成后,预计每年可节约运行经费33万元,4.23年即可收回投资成本,具有较好的经济效益。同时可有效解决管道堵塞、环境污染等问题,具有较好的社会效益和环境效益。潘军刚 2016环境科学与管理2016,41,6:1
2Water quality of reclaimed water from treated urban wastewater in Chaobai River Basin,North China显示文摘The utilization of reclaimed water could be an efficient tool to alleviate water scarcity,especially for dry river augmentation.However,it is crucial to monitor water quality to ensure safety to human health and to avoid negative effects on the environment.Reclaimed water samples were collected bimonthly from May to November in 2010 in Chaobai River,and the physiochemical parameters were determined.The main results are as follows:The parameters exceeding the threshold value of the water guidelines are mainly nutrition related to nitrogen and phosphorus,which are known to increase the risk of eutrophication in surface waters.Additionally,nitrite and nitrate can be detrimental to human health.The majority of the parameters have a peaking concentration in May,whereas others either show significant temporal variation over the entire period or remain relatively constant in all four months.Correlation analysis shows that some parameters(pH,T and B) have no significant correlation with others,whereas significant positive correlation was found for Sr with EC and TDS,for CI with TDS,for Si02 with TP and for NO3-N with TN and a significant negative correlation between SO4 and Ba.According to principal component analysis,60.108%of the total data is represented by dominant solutes,and the second principal component with a percentage of 31.876 comprises parameters related to nitrogen.Subsequent cluster analysis of parameters identified four groups,which represent different compositions,and samples in May differ from others.Yilei Yu Xianfang Song Yinghua Zhang Fandong Zheng Licai Liu 2014Chinese Journal of Population,Resources and Environment2014,12,2:1
