A treatment agent of wastewater containing heavy metals comprising sodium sesquicarbonate as a principal component and a mixture in which EDTA(ethylenediaminetetraacetic acid) and sodium metabisulfite are mixed at a proper ratio is provided to obtain an effect of remarkably improving the removal performance of heavy metals such as lead(Pb), cadmium(Cd), iron(Fe) and copper(Cu), and a preparation method of the treatment agent is provided. In a treatment agent for removing the heavy metals from wastewater contaminated with heavy metals, the treatment agent of wastewater containing the heavy metals is prepared by mixing 70 wt.% of sodium sesquicarbonate, 5 wt.% of EDTA(ethylenediaminetetraacetic acid), 5 wt.% of sodium metabisulfite, and 20 wt.% of water. In a treatment agent for removing the heavy metals from wastewater contaminated with heavy metals, the treatment agent of wastewater containing the heavy metals is prepared by mixing 30 wt.% of sodium sesquicarbonate, 20 wt.% of EDTA(ethylenediaminetetraacetic acid), 30 wt.% of sodium metabisulfite, and 20 wt.% of water. In a preparation method of forming a treatment agent for removing the heavy metals from wastewater contaminated with heavy metals, the preparation method of the treatment agent of wastewater containing the heavy metals comprises the process of drying the slurry at 60 to 65 deg.C for 2 hours after preparing a slurry by mixing 70 wt.% of sodium sesquicarbonate, 5 wt.% of EDTA(ethylenediaminetetraacetic acid), 5 wt.% of sodium metabisulfite, and 20 wt.% of water.
