摘要
In order to improve the water environment of Songhua River,develop and maintain a healthy water cycle,the article has made theoretical and mathematical analyses of wastewater treatment and reuse.It proposes that the important link of sustainable utilization of urban water resources is wastewater treatment and reuse,and the main approach of sustainable utilization of water resources is water saving,wastewater reclamation and reuse.Through establishing the cost equation of recycle water system and optimizing it by Matlab,an optimal treatment scale of the city recycle distributed wastewater system is obtained.The principles of recycle water system in northern areas are put forward based on the research of sustainable utilization of water resource in Songbei district.The results can provide experiences and references for water saving,wastewater reclamation and reuse in northern cities of China.
