淮河流域水环境保护政策评估 总被引:5,自引:1,他引:4
搜集各部门已有数据对淮河流域水环境保护政策体系、管理行动、排放控制以及水质进行评估.结果表明,淮河流域水质没有明显改善和恶化的趋势,规划目标没有达到,污染物排放没有得到控制,工业和生活污染源是水质超标的首要原因,部门间水质和排放监测缺乏协调,数据质量低,水环境保护投入落后于社会经济发展.建议实施严格的排污许可证制度;尽快建立流域水环境保护信息共享平台;中央政府通过许可证、专项资金等形式承担更多的流域水环境保护责任;完善水环境保护规划体系,以较长的时间尺度,制定流域水环境保护的战略性基础规划. 相似文献

总悬浮颗粒物(简称TSP)是大气环境监测的必测项目之一。其监测方法采用滤膜采样,重量法。它是以采样动力抽取一定体积的空气,并用滤膜将TSP样品捕集。滤膜在采样前后的增重与采样体积之比,可得TSP的含量mg/m~3。采样是TSP监测的首要环节,国家环保局1989年7月发布的《HYQ1-89环境保护专用仪器、设备技术要求》已对TSP采样器的 相似文献

基于聚类分析和水质标识指数的水质评价方法 总被引:11,自引:0,他引:11
为探讨一种适用于大尺度、多断面和长时间的水质评价方法,用层次聚类分析将2006~2008年海河5个监测断面的165个水质样本分为20组,并用方差分析验证了结果的可靠性。用综合水质标识指数表示水质样本的综合特征,与单因子评价法相比,该方法充分考虑了最差水质因子的影响,避免了单因子评价法以偏概全的缺陷,且分辨率高。将评价结果分解到各断面,结果表明:密云水库、官厅水库和于桥水库的水质处于II~III类水之间,可满足作为饮用水水源水的要求,三岔口断面大部分时间为IV~V类水,张家口八号桥断面全年有6个月以上水质属于劣V类。 相似文献

我们于1995年3月 ̄4月调查了武汉市高位铁皮水箱的供水质量。结果表明:高层住宅水箱近年虽曾清洗消毒,但高层用户龙头水及水箱水中游离性全氯未达标比例较大,分别为73.3%和66.7%。个别底层住户水样中铁超标。高位水箱水样中细菌总数超标比例为20%。反映了高层住宅二次供水中在水的输送、贮存过程中有二次污染存在。经水样监测指标相关性和灰色关联性分析,认为游离性余氯可作为常规监测高层住宅二次供水质量的 相似文献

The initial state implementation plans concentrated on attainment of the ambient air quality standards in the relatively polluted areas of the country. Many of these plans must now be modified to ensure that the ambient standards will be maintained for the foreseeable future, and to ensure that significant deterioration of air quality in clean areas of the country is prevented. The existing implementation plans currently contain many measures which are applicable to the maintenance and deterioration efforts, but additional measures must also be developed. Many of these additional measures will involve future planning activities—most common of which will be land use planning activities. The point is made that, after existing sources have reduced their emissions to the lowest practical level, further air pollution control can only be accomplished by implementing rational planning procedures for management of any new sources of air pollution. This will require extensive cooperation among the air pollution control community; regional, state, and local planning agencies; state and local governments; and the general public in order to ensure that future land use plans include appropriate air quality considerations. 相似文献

Globally, urban growth will add 1.5 billion people to cities by 2030, making the difficult task of urban water provisions
even more challenging. In this article, we develop a conceptual framework of urban water provision as composed of three axes:
water availability, water quality, and water delivery. For each axis, we calculate quantitative proxy measures for all cities
with more than 50,000 residents, and then briefly discuss the strategies cities are using in response if they are deficient
on one of the axes. We show that 523 million people are in cities where water availability may be an issue, 890 million people
are in cities where water quality may be an issue, and 1.3 billion people are in cities where water delivery may be an issue.
Tapping into groundwater is a widespread response, regardless of the management challenge, with many cities unsustainably
using this resource. The strategies used by cities deficient on the water delivery axis are different than for cities deficient
on the water quantity or water quality axis, as lack of financial resources pushes cities toward a different and potentially
less effective set of strategies. 相似文献

Assessment and rationalization of water quality monitoring network: a multivariate statistical approach to the Kabbini River (India) 总被引:1,自引:0,他引:1

The establishment of an efficient surface water quality monitoring (WQM) network is a critical component in the assessment, restoration and protection of river water quality. A periodic evaluation of monitoring network is mandatory to ensure effective data collection and possible redesigning of existing network in a river catchment. In this study, the efficacy and appropriateness of existing water quality monitoring network in the Kabbini River basin of Kerala, India is presented. Significant multivariate statistical techniques like principal component analysis (PCA) and principal factor analysis (PFA) have been employed to evaluate the efficiency of the surface water quality monitoring network with monitoring stations as the evaluated variables for the interpretation of complex data matrix of the river basin. The main objective is to identify significant monitoring stations that must essentially be included in assessing annual and seasonal variations of river water quality. Moreover, the significance of seasonal redesign of the monitoring network was also investigated to capture valuable information on water quality from the network. Results identified few monitoring stations as insignificant in explaining the annual variance of the dataset. Moreover, the seasonal redesign of the monitoring network through a multivariate statistical framework was found to capture valuable information from the system, thus making the network more efficient. Cluster analysis (CA) classified the sampling sites into different groups based on similarity in water quality characteristics. The PCA/PFA identified significant latent factors standing for different pollution sources such as organic pollution, industrial pollution, diffuse pollution and faecal contamination. Thus, the present study illustrates that various multivariate statistical techniques can be effectively employed in sustainable management of water resources. Highlights ? The effectiveness of existing river water quality monitoring network is assessed ? Significance of seasonal redesign of the monitoring network is demonstrated ? Rationalization of water quality parameters is performed in a statistical framework 相似文献

An early warning and control system for urban, drinking water quality protection: China’s experience
Dibo Hou Xiaoxuan Song Guangxin Zhang Hongjian Zhang Hugo Loaiciga 《Environmental science and pollution research international》2013,20(7):4496-4508
An event-driven, urban, drinking water quality early warning and control system (DEWS) is proposed to cope with China’s urgent need for protecting its urban drinking water. The DEWS has a web service structure and provides users with water quality monitoring functions, water quality early warning functions, and water quality accident decision-making functions. The DEWS functionality is guided by the principles of control theory and risk assessment as applied to the feedback control of urban water supply systems. The DEWS has been deployed in several large Chinese cities and found to perform well insofar as water quality early warning and emergency decision-making is concerned. This paper describes a DEWS for urban water quality protection that has been developed in China. 相似文献
