Ecological and Economic Tools for Assessing Efficiency of Physicochemical Wastewater Treatment Methods

Resumo

Ecological and economic characteristics of wastewater treatment processes are studied by the example of assessment of effectiveness of synthetic and natural adsorbents and biocide flocculants. The norms for the maximum allowable discharge are calculated taking account of the achieved wastewater treatment quality indexes. Calculations of ecological hazard index that determines the adverse effect of highly concentrated wastewaters on the environment are presented. The effectiveness of nature protection measures for reducing the inflicted damage is shown.
