Microbiological purification of wastewater

Abstract

Water plays a vital role in the biosphere as a component of all living beings, participates in photosynthesis, a basic life process on the planet, and represents the environment to a large number of living beings. In water ecosystems, pollutants come from two sources, both natural and anthropogenic. The main anthropogenic sources of pollutants are municipal wastewater, industrial wastewater, and water from agriculture. Microbiological degradation of organic pollutants is the only possibility of their removal from water. In this paper, the possibilities of purification of wastewater are considered, with special emphasis on the role of microorganisms in the process.

Voda ima vitalnu ulogu u biosferi kao gradivna komponenta svih živih bića, učestvuje u fotosintezi, bazičnom životnom procesu na planeti, i predstavlja životnu sredinu velikom broju živih bića. U ekosisteme voda, polutanti dospevaju iz dva izvora, prirodnim i antropogenim putem. Glavni antropogeni izvori polutanata su komunalne otpadne vode, industrijske otpadne vode, vode iz poljoprivrede. Mikrobiološka razgradnja organskih zagađivača, predstavlja jedinu mogućnost njihovog uklanjanja iz vode. U ovom radu, razmatraju se mogućnosti prečišćavanja otpadnih voda, s posebnim akcentom na ulogu mikroorganizama u procesu.
