Pharmaceutical wastewater treatment method

Pharmaceutical wastewater treatment method

pharmaceutical wastewater as refractory industrial wastewater, on the basis of different kind of drugs, production techniques, and gap between water quality and wastewater composition is very complicated.

at present, in order to make the water quality standard, than use a variety of pharmaceutical wastewater treatment detection.

the yixing environmental protection research institute of Harbin Institute of Technology, jiangsu, appropriate environmental protection research institute co. , LTD. , vice general manager of min XiangFa pointed out:

flocculation precipitation - Hydrolysis acidification - Sequencing batch activated sludge process ( SBR) Technology, combination by electrolytic process and SBR process, a combined anaerobic - Aerobic reaction process, air flotation - Hydrolysis - Aerobic process is widely used four process. The four process combined with the advantages of their craft of wastewater pretreatment, improved the wastewater biological sex, the difficulty of the follow-up biological treatment is reduced, at the same time, COD removal rate is high.

four kind of technology in the process of practical application conditions there are requirements for operation, such as electrolytic process and SBR method combining process when the pH value of 7 or so, electrolytic effect is relatively good; Compound bioreactor drastic fluctuations (when the temperature More than 2 - 3℃) , can lead to a sharp decline in anaerobic reactor gas production and the reducing of the treatment effect, therefore, in the actual pharmaceutical factory design and operation of sewage treatment methods to try to keep the temperature stable.
