| Abstract: | Trimeric quaternary ammonium surfactants are newly developed surfactants, their widespread synthesis and utilization results in a great amount of scouring wasterwater of high COD, which is unmanageable. The present investigation aims to find a new type of organo-bentonites modified by the scouring wastewater and to treat the scouring wastewater at the same time. Results of adsorption experiments of phenol and formaldehyde by the modified bentonite show that, at the optimal ratio 24 % (W/V) of modified bentonite to scouring wastewater, the removal rate of phenol and formaldehyde by FTAT scouring wastewater modified bentonite is 3.53 times and 2.48 times higher than that of Na-bentonite, and the COD of treated scouring wastewater reduces to below 200 mg/L, meeting the second level of Standards for Discharge of Water Pollutants from the Ammonia Industry of China. |
