Title: Pentachlorophenol mineralization in an immobilized soil bioreactor

Abstract

The biological degradation of pentachlorophenol (PCP) was conducted in a new type of reactor-the immobilized soil bioreactor. In this bioreactor soil particles having natural microbial activity in degrading the target pollutant are entrapped into a solid membrane with a large pore size distribution. The resulting {open_quotes}immobilized soil{close_quotes} system can be easily supplied with dissolved mineral salts, oxygen and target pollutant and as a result an active microbial consortium will be quickly established. This consortium is later used for treatment of aqueous solutions of the pollutant, for instance, contaminated ground water. We have studied the process of PCP biodegradation in both batch and continuous regime. our results showed that the volumetric effectiveness of the process of PCP mineralization in the immobilized soil bioreactor is between 7 and 4000 times higher than results reported in the literature. It has been found that both chlorine and carbon atoms of PCP are at least 99% mineralized. 7 refs., 4 figs., 1 tab.
