生态文明是人与自然、人与人和谐双赢的文明.党的十七大将生态文明建设确立为一项重要的国家发展战略,使之成为中国特色社会主义建设事业总体布局的重要组成部分.建设生态文明涉及器物、行为、制度和观念等四个层面的建设,其中观念层面的建设是基础,将为其他层面建设提供智力支持和价值指导,而观念层面建设主要依靠教育来实现,因此,加强生态文明教育势在必行. 相似文献

The powdered activated carbon which had adsorbed phenylglycine solution from pharmaceutics factory can be regenerated by
mean of irradiation of high-energy electron beams in oxygen, nitrogen and water vapor respectively. The effects of radiation dose and beam
current on regeneration of activated carbon in different atmosphere were studied. Differential scanning calorimetry (DSC) and the iodine
number of activated carbon were used to monitor the change of carbon adsorption. The results show that the powder activated carbon
polluted with phenlglycine could be regenerated effectively by irradiation of high energy electron beams in nitrogen stream. The generation
did not need high temperature, and the weight loss of carbon and energy consumption were minimum. 相似文献

基于近九十年师范办学的历史传统,在发展教育理论基础之上,我们提出了"发展教育"的办学理念,涵括增长极限观、综合发展观、以人为中心的发展观、可持续发展观等内容。我们认为,学校的办学规模和办学质量的发展要取得内在平衡,特别是当办学规模达到极限后,办学质量的提升才是学校的生命力所在。学校教育应以学生的全面发展、富有个性、可持续发展为出发点。因此,我们的教育目 相似文献

Urban wastewater treatment techniques could not be applied to improve the pollutant removal efficiency,due to its characteristics of closed and quiescent conditions of the static lake water.In this study,natural zeolite and coal cinder were chosen as filler compounds of the ecological filter.Static and dynamic experiments were carried out to study the remediation efficiency.Experimental data show that removal efficiency of ammonia nitrogen (NH + 4 -N) reaches 85% in both static and dynamic patterns and its removal efficiency reaches 97% when the recycling period is 1 h in dynamic condition.The maximum removal efficiency of nitrite nitrogen (NO-2 -N) reached 98%,and the removal efficiency of total nitrogen (TN) is a maximum of 84%.The final effluent concentration of total phosphorus (TP) is 0.079 mg/L.Effluent recycling could improve the nutrient (N,P) removal efficiently.Dissolved oxygen (DO) concentration could remain high with the water cycling.The filter works efficiently on regulating pH to the standard level of healthy water. 相似文献
