Study on Quality Change of Roof Rainwater and Sand Filter Column Effect
Based on pollutants of roof rainwater runoff in Jinan urban area,the paper reveals dynamic regularity of different pollutant varying with rainfall and water quality changing with season.According to pollutants in roof rainwater,a sand filter system was designed to remove pollutants.The test results showed that the system was effective in removing pollutants in roof rainwater,the average removal rate of turbidity reached 87％,and the average removal rate of suspended solids was above 70％,the sand column was also effective for purification of chroma,ammonia nitrogen,volatile phenol,nitrite nitrogen,zinc and so on.Filtering test provides basic research for utilization of roof rainwater in Jinan.
