Wastewater treatment of a certain pharmaceutical and chemical plant

1、 Wastewater quality analysis

(1) Water quality composition

The water quality composition of the factory is relatively complex, with many by-products. The reaction raw materials are often solvent like substances or cyclic compounds, which increases the difficulty of wastewater treatment; The high content of pollutants in wastewater is caused by incomplete reaction of raw materials and the entry of a large amount of solvent media used in raw materials or production into the wastewater system; There are many toxic and harmful substances, and many organic pollutants in fine chemical wastewater are toxic and harmful to microorganisms, such as halogen compounds, nitro compounds, dispersants or surfactants with bactericidal effects, etc.

(2) Water quality indicators
