To provide a treatment agent and a treatment method capable of preventing pollution. A heavy metal-containing waste treating agent comprising a water-soluble polymer having a colloid equivalent value of -6 to +1 meq / g and a molecular weight of 100,000 to 15,000,000, and the treating agent. A method for stabilizing heavy metal-containing waste, comprising mixing and kneading the heavy metal-containing waste and water as required. |
