Common reduction dechlorination technology includes the catalysis hydrogenation dechlorination, iron powder reduction dechlorination, biological dechlorination and electrocatalysis dechlorination and so on.
Catalytic hydrogenation is a kind of green and efficient technology, but the shortcoming of catalyst is easy poisoning.Although iron powder reduction dechlorination is simple and inexpensive , activity is not high, in the synergy of precious metals, the efficiency of dechlorination with iron powder reduction method can greatly improve, but for the precious metal recycling is more difficult.
Biological treatment technology is a better method for clearing organics of the water, but only effectively treats with biocompatible, the abiotic biological compatibility compound such as chlorinated aromatic hydrocarbons is not applicable.
Electrocatalysis dechlorination is under NPT, studies have shown that this method for chlorinated aromatic compounds with stable chemical properties has better dechlorination effection, has advantages such as reaction selective, simple reactor and free of secondary pollution, thus becomes a recent research hot spot of rapid, efficient dechlorination direction. |
