摘要

依据人工景观水体构造,分析城市住宅区人工景观水体特征及污染原因。设定水质指标实际测试值和规范值,利用水体污染分析的升Г型分布指数公式分析水体污染等级,依据等级分析结果,对水体富营养化各个等级指标进行数据预处理,通过消除不同指标之间的差异。选择滤除装置,设置曝气生物滤池运行操作流程,通过微絮凝化学除磷、生物沸石去除氨氮,实现水体污染物高效滤除。在地表水环境质量标准基础上,对该工艺运行进行监测分析,由分析结果可知,该工艺滤除效果良好、时间短,符合城市住宅区用户对景观建设的高标准要求。
        According to the structure of artificial landscape water body,the characteristics and pollution reasons of artificial landscape water body in urban residential areas are analyzed. The actual test value and standard value of water quality index are set,and the water pollution grade is analyzed by using the formula of ascending type distribution index of water pollution analysis.According to the result of grade analysis,the data of each grade index of water eutrophication are pretreated,and the difference between different indexes is eliminated. Select the filter device,set up the operation process of biological aerated filter,through micro-flocculation chemical phosphorus removal,biological zeolite removal of ammonia nitrogen,to achieve efficient water pollutant removal. Based on the surface water environmental quality standard,the process operation was monitored and analyzed. The results show that the process has good filtering effect and short time,which meets the high standard requirements of urban residential users for landscape construction.
