1、常见的还原脱氯技术包括催化加氢脱氯、铁粉还原脱氯、生物脱氯和电催化脱氯等。
2、催化加氢是一种绿色高效的脱氯技术，但其有催化剂容易中毒的缺点；
铁粉还原脱氯虽然简单廉价，但是活性不高，在贵金属的协同作用下，铁粉还原法脱氯效率能极大提高，但贵金属的回收较为困难。
3、生物处理技术虽是清除水中有机物的较好方法，但只能有效处理与生物相容的有机物，对非生物相容的许多氯代芳烃化合物则不适用；
4、电催化脱氯可在常温常压下进行，已有研究表明该方法对化学性质非常稳定的氯代芳烃类化合物具有较好的脱氯效果，具有反应选择性好、反应器简单、无二次污染等优点，从而成为近年来高效快速脱氯方向的研究热点。

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.
