企业开展污水再生回用工作存在的主要问题及对策 总被引:1,自引:1,他引:0
我国水资源相当贫乏 ,污水再生回用是一项既缓解供水紧张状况 ,又可获得经济效益、减轻环境污染的良好措施。除市政府外 ,大型企业也可以开展此项工作。从目前情况看 ,企业开展污水再生回用工作实例较少 ,并在实施过程中存在资金、技术、认识水平、效益、配套设施等主要问题。通过分析指出 :发挥政府职能 ,转变用水观念 ,拓宽筹资渠道 ,开发回用水市场 ,降低成本等是企业解决此问题的有效对策和措施。同时对秦皇岛港务集团公司污水再生回用工作的成功实践进行了分析介绍。 相似文献

Reuse of wastewater for irrigational purposes in agriculture has been a widely applied practice all around the world compared to such applications in industries. In most of the developing countries, high costs of wastewater treatment stimulate the direct reuse of raw or partly treated effluent in irrigation despite the socio-cultural objections in some countries regarding religious rituals towards consuming wastewater. In Turkey, reuse applications in agriculture have been in use by indirect application by means of withdrawing water from the downstream end of treatment plants. Such practices affected the deterioration of surface water resources due to the lack of water quality monitoring and control. However, more conscious and planned reuse activities in agriculture have recently started by the operation of urban wastewater treatment plants. Turkey does not face any severe water scarcity problems for the time being, but as the water resources show the signs of water quality deterioration it seems to be one of the priority issues in the near future. The industrial reuse activities are only at the research stage especially in industries consuming high amounts of water. In-plant control implementation is the preferred effort of minimizing water consumption in such industries. The current reuse activities are outlined in the article forming an example from a developing country. 相似文献

Competition for water can be resolved by construction of more facilities for storing water in wet years for use in dry years, by weather modification, watershed management, urban and agricultural water conservation, reuse of sewage effluent and other wastewater, desalination of saline water, water banking and transfer of water rights or other changes in water use. Reuse of wastewater requires treatment so that the water meets the quality requirements for the intended reuse. Groundwater recharge and recovery can play an important role in the treatment and storage of wastewater for reuse—agricultural, urban, and industrial, as well as potable. Often, water shortages are only shortages of cheap and abundant water, and competition problems can be resolved by good planning and management if the public is willing to pay the price and to accept changes in water use. 相似文献

The number of people who have limited access to high-quality water has increased, and while this is a growing global crisis, water issues, problems and solutions are often seen as localised. Water reuse and reclamation will play a significant role in achieving sustainability and public health protection in the future. The wastewater and reuse community should be responsible for monitoring sewage impacts and improvements as demonstrated through pathogen reduction with appropriate treatment. Viruses, Cryptosporidium and Giardia can all be reduced during treatment anywhere from 99% to 99.9999%, achieving drinking water quality, if so desired. Recommendations to achieve better access to scientific information for decision making include: 1) developing a global data base for biological contaminant loading from wastewater and 2) defining the public health protection via reuse and reclamation. 相似文献

Abstract The increase in demand for the limited raw water resources in the Palestinian Territories has led to the proposals for use of treated wastewater as one alternative for alleviating water shortages and for optimizing the use of water resources. Wastewater reuse is a multi-discipline and important element of water resources development. Wastewater usage releases high quality water for drinking and other purposes. Quantitative, economic, and social aspects related to wastewater reuse in the West Bank are discussed. Through analyses of the estimated cost and expected water quantities, the paper investigates the economic feasibility of wastewater reuse. Social acceptance is elicited by means of questionnaires, which have been applied to farmers and inhabitants in different areas of the West Bank. Wastewater reuse can compensate for about 10 percent of irrigated agriculture, which contributes 35 percent of the total value of the Palestinian agricultural sector. The paper presents an analysis of the main aspects of wastewater reuse and defines an approach to the beneficial use of wastewater as a component that should be considered in the strategy for the overall management of water resources in the Palestinian Territories. 相似文献
