초록

The study investigated the discharge of various pollutants, including APEs like OPE (20 %) and NPE (80 %), in industries such as surfactants, solvents, disinfectants, adhesives, and insecticides. The primary survey identified water pollutant candidates exceedance of discharge standards for chloride ions (2), sulfate ions (1), octylphenol (OP) (1), and nonylphenols (NPs) (5). OP and NPs were universally detected across industries. An analysis of OP and NPs decomposition patterns from Step 1 to Step 4 for wastewater discharge facilities and a secondary survey on the treatment efficiency of wastewater treatment methods were conducted. Analysis of wastewater treatment methods in eight facilities showed increased OP and NPs concentrations in HF and MF industries, ranging from 195.4 % to 402.3 %. Activated sludge treatment efficiency ranged from 17.9 % to 99.9 %, while activated carbon treatment ranged from 83.1 % to 99.5 %. SM, AM, MF, VP, and HF facilities can be effectively treated using either the activated sludge method or the SBR method. Recommendations include activated carbon post-treatment for WC and WD facilities, and enhancing biological treatment or additional measures like Reverse Osmosis and A/C Filter for CP facilities to address APE removal. Correlation analysis showed a positive correlation size order of NPs-Phenols > OP-NPs > OP-Phenols based on primary analysis data.
