城市景观水体污染控制及绿道规划方法研究

Study on Urban Landscape Water Pollution Control and Greenway Planning Methods

水体与绿道是城市景观建设的关键组成部分,由于多种因素的影响,致使部分城市景观水体污染严重,制约城市经济发展,提出城市景观水体污染控制及绿道规划方法研究。构建水体污染物净积累模型,计算水体污染物净积累量,并阐述了工艺参数确定方式。依据多种规则,结合城市实际情况,制定城市景观绿道模式,从而实现水体污染的控制及绿道的规划。实验数据显示:应用提出方法后,水体COD平均浓度数值达到38 mg/L,TN平均浓度数值达到2.4 mg/L,TP平均浓度数值达到0.32 mg/L,绿道服务范围最大值754 km 2,充分证实提出方法应用效果较佳。

Water body and greenway are the key components of urban landscape construction.Due to the influence of many factors,some urban landscape water bodies are seriously polluted,which restricts urban economic development.The net accumulation model of water pollutant is established and The net accumulation amount of water pollutant is calculated.The determination method of process parameters is expounded.According to a variety of rules,the urban landscape greenway model is formulated by combining with the actual situation of the city,so as to achieve the control of water pollution and greenway planning.The experimental data show that after the application of the proposed method,the average COD concentration of the water body reaches 38 mg/L;the average TN concentration reaches 2.4 mg/L;the average TP concentration reaches 0.32 mg/L,and the maximum service range of the greenway is 754 km 2,which fully confirms the application effect of the proposed method.
