川中丘陵区浅层地下水生物慢滤水处理效果的研究

Study on the effect of slow bio-filtration treatment of shallow groundwater in hilly area of Sichuan Province

川中丘陵区浅层地下水生物慢滤工程的试验结果显示出其对常见污染物指标的去除效果。该系统对原水污染物各指标的去除率都在50%以上,而清水池中加臭氧处理后,污染物各指标去除率可达60%以上,出水水质均能达到国家《生活饮用水卫生标准》(GB5749—2006)。此技术可作为农村饮水安全工程建设中的一种实用水处理模式,具有良好的应用价值和推广前景。

The test results using slow bio-filtration treatment of shallow groundwater in hilly area of Sichuan Province show a good effect to reduce common pollution indicators.This system can remove various raw water pollution indicators more than 50%,while after the ozone treatment,this figure is up to 60%,and the water quality can reach the national ＂Drinking Water Health Standards （GB 5749—2006）＂.This technique,which can be used as a practical water treatment model in the construction of rural drinking safety project,has a good application value and promotion prospects.
