PROPERTIES SIMULATION OF ANTHROPOGENIC FILTER DAMS AND FIELDS

Вылков А.И., Удилов А.Е.
Model for anthropogenic filtration dams and fields functional simulation was proposed by us. Such fields can be used for purifying of wastewater, and recycled water in the closed system of water supply at the gold mining industryfrom suspended particles. The influence of the following factors on the target properties of filtrating dams and fields (speed of filtration and purification)was analyzed by means of simulation modeling: granulometric composition and diversity of its distribution along the direction of filtration, porosity and diversity of its distribution, the difference in water levels in the headrace and diverter trenches. Concluded that in design phase of the filtrating dam, the main emphasis should be given to the selection of filtrating material and its granulometric composition, which has the greatest impact on the target filtration properties of dams and fields. Also concluded that for the practical application the most promisingdam is heterogeneous, having the contents of large fractions decreasing, and the small fractions increasingalong the direction of filtering.
