Abstract

The invention discloses a fine chemical wastewater treatment process. The fine chemical wastewater treatment process comprises the following steps of: (1) treating by pre-oxidation, namely, adding wastewater to a floatation tank through an adjusting tank, and then adding an inorganic strong oxide to the floatation tank to treat the wastewater by oxidizing; (2) performing hydrolytic acidification; (3) performing biological treatment, namely, performing biological treatment for the acidified wastewater through an anaerobic tank and an aerobic tank in sequence; (4) treating through activated sludge, namely, treating the wastewater subjected to biological treatment through a mudpack MBBR (Moving Bed Biofilm Reactor) and activated sludge; (5) flocculating and settling, namely, transferring the treated activated sludge into a flocculating and settling tank, then adding 30% of sodium hydroxide to adjust the pH to be 8 to 9, adding 30-4-mg/L of PAC (Poly Aluminium Chloride), and finally adding 70 to 90mg/L of flocculating agent to separate mud and water; and (6) deeply treating, namely, performing rough filtration and fine filtration for the output water in sequence, and then treating by an RO (Reverse Osmosis) film. With the adoption of the fine chemical wastewater treatment process, the biodegradability of wastewater can be improved, organic matters in wastewater can be removed efficiently, the wastewater can be recovered and recycled, and thus the water resource is saved; in addition, the recovery process is short, and the system recovery rate is high.
