The Anaerobic degradation of perchloroethylene under iron reducing condition was studied by batch experiments in the microcosm with the temperature of 20degC. It showed that PCE could be sequentially dechlorinated to TCE and then to DCEs. TCE appeared at the second day of degradation experiment and a few mug/L of DCEs appeared about 10 days later. But the decrease of the concentration of TCE was not...
The paper introduces the treatment of recirculating water from refinery plant with grid filtration to remove suspended solid to decrease the turbidity in the water.
