Detailed introduction

At present, domestic heavy metal sludge generally has the problem of high heavy metal content, great harm, difficult to treat, high treatment cost, heavy metal sludge stabilization chelating agent is a kind of environmental protection agent specially used for sludge stabilization treatment containing a large number of heavy metals. The product is developed according to the characteristics of heavy metals in sludge, and is a composite stabilizer composed of heavy metal precipitation agent, chelating agent, accelerator and penetrant. The product stabilizes the heavy metal ions in the sludge and does not leach, so as to achieve the purpose of decontamination. It can cooperate with various sludge treatment processes and systems to make the treated sludge meet the landfill requirements of the domestic garbage landfill pollution control standard (GB16889-2008).


Product features


1. The range of precipitation metals and chelating metals is wide, especially the chelating of heavy metals such as nickel, chromium and lead which are difficult to be treated.


2. Good water solubility, good dispersibility, high utilization rate of reagents, stable distribution of sludge treatment performance.


3. It can stabilize a variety of heavy metal ions and is effective for all polyvalent metal ions.


4. Appropriate allocation can be made according to specific sludge conditions and heavy metal content.


5. The sludge performance after treatment is stable and reliable, with a long cycle, which can reach the sanitary landfill standard.


Using range


Heavy metal sludge stabilization chelating agent can be widely used in heavy metal sludge stabilization treatment system, such as electroplating sludge, metallurgical sludge, river sludge, municipal sludge, slag and various industrial and mining industry solid waste treatment system.

Method of use


1. Heavy metal sludge stabilization chelating agent is recommended before sludge dewatering. Powder can be directly added to the sludge conditioning tank, stir evenly, and then dewatering treatment. This product can be added synchronously with polymer flocculant, but it should be avoided to share with metal flocculant, so as to avoid drug failure.


2. Heavy metal sludge stabilization chelating agent can also be used after sludge dehydration, the agent is added in proportion to the tap water for dissolution, mixed with liquid medicine, and sludge can be evenly mixed. If metal flocculant is used for dehydration, the product must be used after sludge dehydration and the dosage should be increased accordingly.


3. Dosage: The specific dosage should be determined according to the actual concentration of heavy metals in the sludge. The recommended dosage should be 10~50 times of the concentration of heavy metal ions. If a variety of heavy metal ions exist, the amount of input should be calculated separately, and the sum is the actual amount required.


4. Technical personnel of the relevant equipment company shall be consulted for the stabilization treatment system, equipment and control process of sludge.



Packing specification and storage


1. Heavy metal sludge stable chelating agent for liquid, provide 25 KG, 1000 KG barrels.


2. It should be stored in a cool, ventilated and dry warehouse. The recommended time limit is 24 months.


3. Keep away from fire and heat, and keep away from acid and strong oxidant.



Matters needing attention


1. Appropriate protective equipment, such as protective glasses, masks and gloves, should be worn during operation to avoid direct contact with the skin.


2. If inhaled or swallowed, seek medical advice immediately.


3. Avoid contact with strong acids or oxidants.


4. Be light in handling to prevent damage to packing or container.


5. Equipped with leakage emergency treatment equipment, empty containers should be disposed by a professional company.
