Pharmaceutical Wastewater Treatment Biological Bacteria Enzyme

Characteristics of pharmaceutical wastewater

The wastewater has complex composition, high organic content, high toxicity, deep chromaticity and high salt content, especially poor biochemical properties and intermittent discharge, which is a difficult industrial wastewater to treat. The common excessive index in wastewater is ammonia nitrogen. How to deal with excessive ammonia nitrogen in pharmaceutical wastewater? Let's have a look!

Ammonia nitrogen treatment method of pharmaceutical wastewater

physical processing

1. Air flotation

Air flotation usually includes various forms such as inflatable air flotation, dissolved air flotation, chemical air flotation and electrolytic air flotation.

2. Adsorption method

Commonly used adsorbents are activated carbon, activated coal, humic acids, adsorption resins, etc. Its wastewater can be treated by coal ash adsorption-two-stage aerobic biological treatment process.

3. Membrane separation method

Membrane technologies include reverse osmosis, nanofiltration membranes and fiber membranes, which can recover useful substances and reduce the total emission of organic matter.

chemical treatment

Chemical ammonia nitrogen agent

The ammonia nitrogen degrading agent is used to directly oxidize ammonia nitrogen into nitrogen gas. This method does not need to stop production and change the process, and has the advantages of flexibility in dosing, environmental protection, no secondary pollution and fast reaction.
