Abstract

Waste, thaw, and rain waters from the territory of industrial enterprises may pollute ground and surface waters, adjoining landscapes. This work presents the characteristics of their quality parameters and also suggests a number of measures permitting them to minimize their harmful impact upon environment. The purpose is the improvement of the technology of the reagent treatment of surface runoff from the territory of auto transport enterprises and of circulating waters for the repeated use by way of modernizing known methods via own original technological procedures and by chemical reagents. This work considers the comprehensive technology of collecting, treatment, and introduction into recycling of surface run-off for the auto transport enterprises, petrol stations.

1. Introduction

Due to the climate change and increasing deficit of clean water, the question of economic use of water has become urgent. The same applies to the introduction of technologies facilitating repeated inclusion of circulating waters into technological processes.

Atmospheric (storm) run-offs from territories of enterprises are formed as a result of washing off admixtures accumulated on their territory of rain, thaw and irrigation water. The specific peculiarity of the storm run-off is its occasionally and distinctly expressed unevenness in discharge and concentration of pollutions. Storm run-offs from territories of industrial enterprises may contain specific admixtures peculiar for this or that production (Barbosa & Fernandes et al., 2012).

Depending on the composition of admixtures accumulated on industrial areas and washed off by the surface run-off, industrial enterprises and their separate territories may be divided into two groups as shown in Table 1. To the first group belong the enterprises of the ferrous metallurgy, machine building, coal, oil, light, bakery, milk producing, food industry, auto transport enterprises, and also separate productions of oil processing, oil chemical, chemical and other enterprises on the territory of which there are no specific polluting substances. To the second group belong the enterprises of non-ferrous metallurgy, coke chemical, microbiological industry and so on.
