住宅小区景观水体水质保持技术应用

Application of Quality Maintenance Technology to Landscape Water in Residential Areas

住宅小区景观水体多为静止的封闭体系,复氧能力较差,自净能力有限,水质难以长期保持。针对住宅小区内景观水体多为微污染、流动性较差、景观要求高等特点,采取了一系列技术措施,构建了一个稳定的集内外源污染控制于一体的综合体系。运行结果表明,该小区景观水体的水质达到了地表水Ⅲ类水质标准。

The landscape water bodies in residential areas are mostly of the static closed system, in which water body aeration ability is low, self-purification ability is limited, and it is difficult to maintain water quality for a long time. Because the landscape water bodies in residential areas have mostly mi- cro-pollution, bad fluidity and high landscape requirement, a series of measures are taken to construct a comprehensive system which stably integrates internal and external source pollution control. The operation result indicates that the landscape water quality in this residential area reaches the third level environmental quality standards for surface water.
