摘要
通过对森林地面水源取水和水质优化处理系统处理前后水体的水量和水质进行测定,分析出水量与水位差的函数关系及水体水质的变化规律,从而掌握收集地面径流水量及处理水质的情况。结果表明:当水源收集处理系统原水水位和净水池水位差为10~15cm时,过滤区单位面积出水量为0.39~0.74m^3/h·m^2,浑浊度去除率为99.48%,肉眼可见物的去除率为100%,可以满足森林消防和游客活动中的大部分用水的(饮用水除外)水质要求,是构建无动力环保林业供水系统中的一项关键技术,为森林水源生态收集处理利用开辟了新思路。
Through measuring the water quantity and water quality of the water body before and after treatment by the forest surface water source water collection and water quality optimization treatment system, analysis of the functional relationship between water quantity and water level difference and the variation law of water quality has been made. Then, the information on surface runoff water collection and water quality handling has also been mastered. The results show: when the water level difference is 10~15 cm, the amount of water produced by the filtration area of system unit is(0.39~0.74)m^3/(h·m^2), turbidity removal rate is 99.48%;the visible removal rate of the naked eye is 100%,which can meet most of the water requirements(except drinking water) in forest fire protection and tourist activities. This is a key technology in the construction of a non-powered environmental protection forestry water supply system, opening up new ideas for the collection and treatment of forest water resources.
