Abstract

The invention relates to a treatment process and device of wastewater produced by erythromycin thiocyanate. The treatment process comprises the following steps of: evaporating high-concentrate wastewater produced by erythromycin thiocyanate by an evaporator in cycle, mixing evaporated low-concentrate water with low-concentrate wastewater produced by the erythromycin thiocyanate, then carrying out hydrolytic acidification, adjusting the pH value, carrying out anaerobic microbial decomposition, precipitating the decomposed wastewater after treatment by active sludge, carrying out ozone oxidization treatment on a clear liquid, and precipitating and discharging after treatment by the active sludge. The wastewater disclosed by the invention adopts the biological treatment process of combining 'four-effect evaporator, hydrolytic acidification, two-stage contact oxidation process and advanced treatment (ozone-Fenton reaction)'. Thus, the treatment device is low in energy consumption, small in investment, high in efficiency, and stable and reliable in treatment effect.

Description

technical field [0001] The invention relates to a waste water treatment process and device, in particular to a treatment process and device for erythromycin thiocyanate production waste water. Background technique [0002] Erythromycin thiocyanate production wastewater is a high-concentration organic wastewater with poor biodegradability. It is difficult to meet the discharge standards only by aerobic treatment process. Anaerobic reaction structures with high organic matter removal rate and good treatment effect are needed. [0003] The content of organic matter, total nitrogen and thiocyanate ions in high-concentration wastewater such as sulfur red mother liquor, recovery solvent and bacterial residue wastewater in erythromycin thiocyanate production wastewater is high, and this part of wastewater needs to be strengthened. The content of total nitrogen and thiocyanate can ensure that the wastewater will not inhibit microorganisms. [0004] Based on the characteristics of t...
