METHOD FOR NEUTRALIZING DREDGED SOIL WASHED WITH ACID

Disclosed is a neutralization method for neutralizing purified dredged soil, which has been washed with an acid in order to remove contaminants. According to the neutralization method, a solid neutralizer is added to and mixed with the purified dredged soil in order to neutralize the purified dredged soil in a solid state. In addition, according to the neutralization method, in order to neutralize used process water in a liquid state, having been used for acid washing, a liquid neutralizer is added to and mixed with the used process water. L'invention concerne un procédé de neutralisation de sol dragué purifié, qui a été lavé avec un acide afin d'en éliminer les contaminants. Selon le procédé de neutralisation, un neutralisant solide est ajouté et mélangé au sol dragué purifié afin de le neutraliser à l'état solide. En outre, selon le procédé, afin de neutraliser l'eau de traitement ayant été utilisée pour le lavage à l'acide à l'état liquide, un neutralisant liquide est ajouté et mélangé à l'eau de traitement utilisée. 오염물질을 제거하기 위해 산세척 처리된 정화 준설토를 중화시키는 중화방법이 개시된다. 상기 중화방법에 따르면, 고체상태의 상기 정화 준설토를 중화시키기 위해서, 상기 정화 준설토에 고상 중화제를 첨가하여 혼합한다. 또한, 상기 중화방법에 따르면, 산세척 처리를 위하여 사용된 액체상태의 사용후 공정수를 중화시키기 위해서, 상기 사용후 공정수에 액상 중화제를 첨가하여 혼합한다.
