Heavy metal chelating agent is a special treatment agent of heavy metal ion wastewater made by using polymer synthesis technology. The reagent uses heavy metal ions such as Cu2 Ni2, Zn2, Zn2, Cr3, Pb2, CD2, and other heavy metal ions produced by polarity group in its own molecule to chelate wastewater with strong negative electric field. The coexisting salts of heavy metals and complex salts (such as EDTA NH _ 3, citric acid, etc.) can also play a full role in the production of flocculant, and have the advantages of coarse flocculation, fast precipitation, fast dehydration and easy post-treatment. The sludge quantity is low, stable and non-toxic, no secondary pollution and so on.
[product characteristics]
1. The method is simple and does not increase the cost of equipment.
2. The concentration of heavy metal ions in wastewater, the number of ions, this product can be treated at one time.
3. The removal of heavy metals in the form of complex salts (EDTA, citric acid, etc.) can also play a good role in the removal of heavy metals.
4. The flocculation effect is good. SEMT-1 is a polymer product, so it can produce good flocculation, resulting in rapid sedimentation and good filtration. 5. The sludge quantity is small and stable, the heavy metals in the sludge will not be dissolved again (except for the strong acid condition, there is no secondary pollution, and the reprocessing is simple.
6. High safety, this product is non-toxic, can be safely used.
7. Sludge dewatering is easy.
