Heavy metal scavenger: 1, can be completed within the normal temperature and a wide range of reaction conditions PH, and from heavy metal ion concentration level of influence; 2, can be better precipitation of various heavy metal ions in wastewater, even if treated wastewater complexes containing ingredients can also handle wastewater discharge standards; 3, and compare similar products in the market, the agent in the removal of heavy metal ions, removal of COD, reducing sludge flocculation has obvious advantages; 4, processing costs than low, the treatment effect good, simple to use, non-toxic and environmentally friendly features. Applies to any heavy metal ions complexed salts such as citric acid, tartaric acid, EDTA, cyanide, NH3, complexed copper wastewater treatment. The following applies to all types of quality: metal impurity metal plating wastewater re-examination or surface treatment process of wastewater generated by the production of circuit boards contains from incinerators or scrubber wastewater garbage permeate in the heavy metal underground metal catalyzed or metal treatment processes produce cooling water use and the amount of wastewater: 1, directly into the wastewater containing heavy metal ions, mixing, increase PH to 7-9, or add a small amount of polyacrylamide solution better. Amount of about 0.05-2 / 1000 heavy metal scavenger tmt wastewater, wastewater depending on the concentration of metal ions may be. 2, if high levels of heavy metal ions in wastewater, first raised by cheap alkaline PH wastewater pretreatment of wastewater to achieve initially most of the heavy metal ions precipitate, and then, and then adjusted to neutral water, added to the product of organic sulfur tmt, according to the first operation. Plus soda and precipitation, PH value should consider the impact of control conditions and interactions of metal ions coexist, various metal ion removal tmt industry best PH value, the list is as follows: PH range residual concentration of metal ions (mg / L) Remarks Cu2 + 7-14≤1 Ni2 + ≥9≤1 Sn2 + 5-8≤1 Zn2 + 9-10.5≤1PH> 10.5 redissolve Fe3 + 5-12≤1PH> 12 redissolution Al3 + 5.5-8≤3PH> 8 redissolved usually NaOH, Ca (OH) 2 as a neutralizing agent. Interaction between metal ions under the influence of coexistence grasp, the best PH value, during commissioning of the heavy metals in the effluent standard indicators as a precondition to the principle of minimum dosage is determined.
