| description | The invention relates to the technical field of heavy metal ion treatment, in particular to a desulfurized sludge heavy metal ion blocking agent and a preparation method and application thereof. The invention provides a desulfurized sludge heavy metal ion blocking agent. The desulfurized sludge heavy metal ion blocking agent comprises the following raw materials in parts by weight: 20-40 parts of chitosan; 1-3 parts of a metal oxide; 1-3 parts of a curing agent; 0.5-1 part of a seaweed extract; and 100 to 150 parts of water. Wherein the seaweed extract is selected from red seaweed extract and/or brown seaweed extract. According to the blocking agent, the chitosan, the metal oxide, the curing agent, the seaweed extract and the water serve as raw materials, heavy metal ions in the desulfurized sludge can be effectively blocked, the heavy metal ions are blocked in the desulfurized sludge, the heavy metal ions in the sludge are prevented from being leached out of soil when the desulfurized sludge serves as a soil |
