Enhanced Microbial Reclamation of Water Polluted with Toxic Organic Chemicals.

摘要

The research was undertaken to develop an inexpensive and easy to operate a microbiological system to reclaim waters contaminated with toxic organic chemicals. Groundwater pollution is a major environmental and public health problem in Colorado. Nitrophenols are widely used in industry as intermediates in the production of dyes, explosives and pesticides. Because of their widespread use, nitrophenols occur as contaminants in industrial effluents and hence in natural waters. The present study was designed to optimize conditions for the biodegradation of 2,4 dinitrophenol (DNP) and other toxic organic chemicals in sequencing batch reactors (SBRs). Optimal conditions for the destruction of toxic chemicals by these bacteria were determined in Sequencing Batch Reactors, a type of biological treatment system.
