Sewage Treatment Plants as a Decision Problem of Businesses and Municipalities

摘要

This paper deals with the assessment of different types of sewage treatment plants which can be included in the so called small sewage treatment plants category. Special attention is devoted to an environmental impact valuation of the reed bed sewage treatment plant (further RBSTP). Features and functions of different sewage treatments are analysed and advantages and disadvantages of the RBSTP and their utilisation opportunities are discussed. Concepts of efficient environmental investments are compared to the traditional methods of the economic evaluation.
