The present invention relates to a water treatment agent, a method for preparing the same, and a water treatment system and in situ treatment system for underground water using the same. More specifically, the present invention relates to a water treatment agent, a method for preparing the same, and a water treatment system and in situ treatment system for underground water using the same, wherein the water treatment agent includes: an activated carbon support; and manganese oxide nanoparticles which is adsorbed to the activated carbon support, has a particle size of 1,000 nm or less, and is formed by respiration and metabolic actions of manganese oxidizing bacteria. According to the present invention, by using the activated carbon support to which biogenic manganese oxide nanoparticles are adsorbed, adsorptive removing and oxidative removing are simultaneously achieved, and thus trace amounts of toxic materials included in water may be efficiently removed. Also, since the biogenic manganese oxide nanoparticles are secured to the activated carbon support, the biogenic manganese oxide nanoparticles is prevented from loss, and thus, the present invention can be applied to a commercialization process. In addition, since the biogenic manganese oxide nanoparticles are prepared in an environmentally friendly manner, generation of contaminants during a preparation process can be minimized and a performance of removing contaminants is better than manganese oxide nanoparticles which are chemically synthesized. Further, by using the activated carbon as a support, a performance of removing an organic contaminant is particularly excellent than in the case where the conventional support is used. |
