Determination of Wastewater Purification Index under Joint Action of Several Pollution Sources in Marine Water Areas

Abstract

Active use of marine water areas makes necessitate a rational ecological planning of human activities in the coastal zones. The difficulty of solving environmental problem is that in marine water aria come pollutants from many sources of all kinds. In our research for solve the problem of determining the requirements for water users on the basis of prediction formed functional for each pollutant and source of pollution. Minimizing this functional under various constraints define the requirements for each water users.

The development of a new method for making justified decisions by municipal authorities in the management of territories on the basis of the results of the environmental express-control of the state of various media

“…Medium and small water bodies in large cities include lakes, ponds in parks and recreation areas, as well as small and medium-sized rivers and streams (for example, in St. Petersburg -Melnichnyy Ruchey, which can be compared to a small river) [8][9][10]. In most cases, these rivers and streams flow into a large river that flows through the city, or into the gulf (for example, Gulf of Finland) on the coast of which the city is located, rarely directly into the sea.…”

“…This is due to the different types of pollution and sources of them creation (for example, industrial and transport enterprises, building objects, etc.) [5][6][7][8][9][10][11][12]. It is very difficult to quickly monitor the ecological situation [13][14][15].…”

Environmental express monitoring of territory and water bodies at various stages of construction and improvement

“…In conditions of high technological load on the environment, especially in large cities such as St. Petersburg, the role of enviromental monitoring of the territory and water bodies to ensure safe living increases [1][2][3][4][5][6]. One of the problems that arises in all countries of the world is the control of the state of the environment during the various works related to the construction and improvement [4,[6][7][8][9][10]. In most countries of the world (the Russian Federation is no exception), low-skilled workers, cheap and poorly packaged building materials are used to reduce the costs of work.…”

“…Construction materials and industrial garbage are placed on the site with violations of their storage conditions. In the majority of situations this leads to a temporary littering of the site and penetration of hazardous substances into the soil, water drains, atmosphere and plants [4,7,[10][11][12][13][14]. These substances begin to react with water (more often with precipitation) or with each other and pose a significant threat to living organisms [3,10,11,12,15].…”

“…An important role in this situation is played by fast reliable methods of express control of condensed matter that can give information on the presence of deviations in a medium from the standard state by in-situ measurements [1,2,10,[16][17][18]. This makes it possible to quickly identify such foci of pollution.…”
