本研究旨在营造出高效便民、资源节约、环境友好的城市公共体育空间，从而实现城市公共体育空间建设的可持续性发展。首先以现状调研为手段，从物理设施分布及市民活动两方面入手，分析了当前城市公共体育空间的优势和不足。其次，在充分研究国内外相关案例的基础上，不再拘泥于单纯的空间层面，提出了涵盖运动空间（Sport-space）、生态友好（Ecology-friendly）、资源集约（Resource-intensive）3个要素的SER理论。最后，对城市公共体育空间体系的构建进行了初步设计。 相似文献

Bioflocculants have received increasing attention in research because they are low cost, non-toxic, biodegradable, operationally simple and useful in many water and wastewater treatment applications. In this study, we focused mainly on the screening of the flocculant-producing strain and its application in oily wastewater treatment. Bacteria strain B-6-1 was isolated by the pyridine screening method. UPC-1 reagent produced by B-6-1 had efficient flocculating activity. It was deduced that the main component of UPC-1 reagent was polysaccharide through purification and analysis. The influence of dosage of reagent, pH value, temperature and oil concentration on the flocculation effect of UPC-1 reagent was investigated. 相似文献
