Biological control and management of the detoxication wastewater treatment technologies

Abstract

Detoxication technologies require the combination of theoretical and practical knowledge of xenobiotic biodegradation, wastewater treatment technologies, and management rules. The purpose of this complicated combination is to propose specialized strategies for detoxication, based on lab- and pilot-scale modeling. These strategies include preliminary created algorithms for preventing the risk of water pollution and sediments. The technologies and algorithms are essentially important outcome, applied in the textile, pharmaceutical, cosmetic, woodtreating, and oiltreating industries. In this paper four rehabilitation technologies for pretreatment of water contaminated by pentachlorophenol (PCP) have been developed in the frame of the European and Bulgarian National projects. Emphasize is put on the biological systems and their potential of detoxication management. The light and transmission electron microscopy of the reconstructed activated sludges the microbial, kinetic and enzymological indicators are presented and approved as critical points in the biocontrol.Tehnologije detoksikacije zahtevaju kombinaciju teorije i prakse ksenobiotske biorazgradnje, tehnologija tretmana otpadnih voda i pravila njihovog upravljanja. Svrha ove slozene kombinacije je da predlozi posebne strategije detoksikacije, a razvijene na osnovu modelovanja na laboratorijskom i pilot postrojenju. Ove strategije ukljucuju preliminarno kreira-nje algoritma za sprecavanje rizika od zagadjenja vodom i talogom. Tehnologije i algoritmi imaju izuzetnu vaznost za tekstilnu, farmaceutsku drvnopreradjivacku i industriju boja. U ovom radu su, u okviru evropskih i bugarskih nacionalnih projekata, razvijene cetiri tehnologije za oporavak pred tretmanom vode, zagadjene pentahlorfenolom (PCP). Naglasak je stavljen na bioloske sisteme i njihove mogucnosti za upravljanje detoksikacijom. Fotografije svetlosne i transmisione elektronske mikroskopije, aktivirano blato, mikrobni, kineticki i eznimoloski indikatori su prikazane i potvrdjeni kao kriticne tacke u biokontroli.
