in modern conditions become widespread trenchless methods for the construction of pipelines. The positive features of their use include increased speed pipeline installation, reducing the volume of excavation, etc. Existing regulatory documents limit the bending of the pipe at low temperatures need to be tested in terms of their applicability to new grades of polyethylene. The aim of this study was to determine the minimum permissible bending radius of the track, the passage of which in the conditions of negative temperatures polyethylene pipes PE80 would maintain its strength characteristics. By using a mathematical model dependency of the elastic modulus and yield point are calculated from the temperature stresses in the walls of pipes of different diameters in bending under different temperatures. In order to establish empirical relationships voltage on the pipe diameter and the radius of its bend procedure is carried out function approximation method of least squares. Presented obtained graphic dependences. Using the values ​​of the yield strength of the material at different temperatures were calculated bending radius of all dimensions. If the production of the track plow trenchless pipe-layer will be considered given the conditions, you will be provided with the necessary conditions for installation.

In the framework of the given article shall be considered a negative impact on microorganisms of ions of zinc, copper and Nickel concentrations in the incoming wastewater to the wastewater treatment facilities of the cities of the Lower Volga region is unacceptably high, which inevitably reduces the quality of the purified water at the indicated metals exceeding the output after biological treatment is more than 30 times). Further, in the proposed article, we describe the results of studies aimed at disposal and treatment of waste activated sludge. The first attempt to use the resulting after biological purification of waste as a secondary raw material for the adsorption material, which retrieves the designated heavy metal ions from wastewaters prior to biological treatment, which allows further the activated sludge fully interact with other ions without losing their functions. As a result, after the biological cycle treated water at the indicated metals, meets the relevant standards.

Long found a direct link between the quality of drinking water and human longevity. Heavy metals getting into our bodies remain there forever, you can get them only with the help of milk proteins and porcini mushrooms. They poison human body, they are also mechanically clog it - heavy metal ions deposited on the walls of the body and thinnest systems clog channels kidney, liver channels, thereby reducing the filtration capacity of these organs. Accordingly, this leads to an accumulation of toxins and waste products of cells of our body, i.e. self-poisoning organism. Ecological forecasting is based on a miscalculation of the possible future behavior of natural systems under the influence of both natural processes and anthropogenic factors. It is therefore advisable during environmental monitoring use spatial modeling of pollutants in the aquatic environment, which will allow to visualize the distribution of pollutants and to reveal the dynamics of pollution. The results of modeling the distribution of pollutants into waters of the Gulf of Taganrog.

Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and they have to be removed or destroyed (bacteria, viruses, organic, sweat, hair, makeup, etc.). Treatment of swimming pool water is much more complicated because of the need to carry out her many times, than drinking water treatment, which is carried out one-time. Based on these studies, given technological solution to improve the efficiency of purification of circulating water in swimming pools, ensuring high environmental and economic performance of water treatment.
