| titleOfInvention | Wastewater treatment method containing heavy metals using calcium and magnesium |
| abstract | The present invention is a method for treating heavy metal-containing wastewater using calcium and magnesium inexpensive materials such as liver water (also known as high juice), which is a byproduct of decontamination process, and gypsum acid wastewater neutralization material, which is a decontamination process waste, and water glass (sodium silicate).n n n Injecting heavy metal-containing industrial wastewater containing calcium and magnesium into the wastewater according to the characteristics of the wastewater, injecting Ca ion concentration of 0.005-0.1mol and Mg ion concentration of 0.005-0.1mol in the wastewater, and stirring the solution to pH with water glass The pH of the solution is adjusted to 7-11 with the aid of caustic soda (sodium hydroxide), and then the solution is stirred for several minutes. Although the flying speed is fast, the polymer material may be used as a coagulant precipitation aid to increase the precipitation and dehydration rate. |
