Technical Field

[0001] The utility model relates to the technical field of chemical waste liquid treatment, in particular to an energy-saving and environmentally friendly chemical waste liquid purification device. Background Art

[0002] The scraps left over from the production and utilization of chemical raw materials, or the waste that is contaminated during the production process and cannot be reused, can be treated by physical treatment (filtration, precipitation, distillation, gas adsorption and other methods to remove solid particles, suspended matter, dissolved matter in the waste), chemical treatment (changing the chemical properties of the waste through neutralization, oxidation, reduction, precipitation, sedimentation and other methods to convert it into harmless or low-toxic substances) and biological treatment (using microorganisms to degrade or transform organic matter in the waste, such as using biofilters or bioreactors).
