The invention relates to an
epoxy chloropropane
wastewater treatment method which comprises the following steps: 1, introducing
epoxy chloropropane
wastewater into an
ozone catalytic oxidation tower, filling a catalyst in the
catalytic oxidation tower, and carrying out
catalytic oxidation decomposition on the
epoxy chloropropane
wastewater to obtain
small molecule and biochemical organic matters; and 2, the oxidized epoxy chloropropane wastewater enters a biochemical
pool for biochemical
decomposition, and the treated epoxy chloropropane wastewater reaches the standard and is discharged. The biological
bacteria culture mode in the biochemical
pool adopts a gradual slow culture mode, firstly, COD (
Chemical Oxygen Demand) of the wastewater is diluted to 500mg / l by adding water, the wastewater is cultured for 5-14 days, then the COD concentration of the wastewater is gradually increased, and the culture is continued. If the COD concentration of the epoxy chloropropane wastewater is higher than 8000 ppm, the wastewater is firstly subjected to
ozone catalytic oxidation, then a middle unit of the
honeycomb type
fixed bed bioreactor is set as a catalytic oxidation regulating water tank, and the wastewater is conveyed to a catalytic oxidation
tower through a pump for secondary oxidation. The wastewater treatment efficiency is improved, and the treatment cost is reduced.
