Abstract

The invention relates to a treatment method for antibiotic pharmaceutical waste water integrated with photocatalyst oxidation reaction and membrane separation. Wherein, taking flocculations, coarse filter and adjust pH value to the waste water putting the water into photocatalyst oxidation reactor with particle titania as catalyst, ultraviolet light as light source and ozone, hydrogen dioxide or chlorine dioxide as oxidizer; degradating organic in water; forcing the waste water into membrane separator to catch most inorganic salt and organic of 97% removal ratio and 98% desalinization ratio and satisfy the recycle standard. This method has high efficiency and the yielding water is colourless and clear.

Description

technical field

[0001] The invention relates to a method for treating antibiotic pharmaceutical industrial wastewater by integrating photocatalytic oxidation reaction-membrane separation, and belongs to the technical field of pharmaceutical wastewater treatment. Background technique

[0002] Antibiotic wastewater is a kind of organic wastewater containing intermediate products, residual antibiotics and organic solvents produced in the antibiotic production process. This type of wastewater has complex components and contains a variety of refractory substances and antibiotics with antibacterial effects. Among them, the content of organic matter, soluble and colloidal solids, and suspended matter is high, the pH range is large, the temperature is high, and it has color and smell. Biological toxicity. At present, aerobic, anaerobic or anaerobic plus aerobic biological treatment methods are mainly used for the treatment of antibiotic industrial wastewater at home and abroad. Ho...
