The Given

The analysis of the possible maximum fluid flow rates when using higher aquatic plants for clarification of recycled water in the pondclarifier of the tailing pond has carried out. The study has been performed on the basis of a mathematical model of a plane slow stationary gravity flow of a viscous fluid in two parallel layers. The results of the study made it possible to determine the fluid velocity through a layer of higher aquatic plants floating on a free surface. The maximum possible velocity depending on the layer porosity has been determined. This value is necessary to determine the rational parameters of the process of clarifying technical recycled water from particles of the given hydraulic size, taking into account the pond-clarifier geometric dimensions. It is shown that the velocity in the layer with higher aquatic plants has been determined by the ratio of two parameters of this layer - porosity and dimensionless resistance coefficient. It has been shown that the maximum velocity value coefficient in the layer with plants floating on free surface depends only on porosity of this layer and does not depend on its resistance coefficient.

Model Animal

With the development of modern industry, the problem of environment pollution becomes more and more serious. It has become an important issue to conduct the environment monitoring rapidly and effective. Fish, alga, higher aquatic plants and benthic macro-invertebrate are always used in the environment monitoring. In recent years, protozoa are widely applied to the monitor of soil environment pollution and water pollution. Protozoa are the most original and the lowest unicellular animals, and they play an important role as the predator and primary consumer in the energy flow and circulation of materials. Protozoa become an ideal model animal in the process of assessing the quality change.
