This paper analyses the treatment effect of the “coagulation-sedimentation-O3-biological sand filtration-GAC” combined process on phthalic acid esters in secondary effluent of municipal wastewater treatment plant and meanwhile evaluate its health risk. The results indicated that when the concentrations of DBP and DiOP in secondary effluent were at range of 0.41 mg/L–0.814 mg/L and 0.23 mg/L–0.36 mg/L, the average total removal rates of DBP and DiOP were 85.10% and 68.11%, and the average concentration of DBP and DiOP in effluent were 0.089 mg/L and 0.091 mg/L, respectively. The quality of the effluent met the requirement of the ornamental scenic environment water inThe Quality of Urban Wastewater Recycling and Scenic Environment Water (GB/T 18921-2002), and the health risks of DBP and DiOP in effluent were at range of 1.99 × 10−12 –2.15 × 10−12/a and 1.48 × 10−11 –1.85 × 10−11/a, respectively, which is lower than the acceptable maximum risk level: 1.0 × 10−6.

Abstract The meat processing industry has many unfavorable impacts to the environment in Turkey. One of these impacts is wastewater treatment. Meat processing wastewater contains large amounts of proteins, fats, nutrients such as nitrogen, and pathogenic and non-pathogenic microorganisms and viruses. The high organic and hazardous content of wastewater causes environmental challenges for the flora and fauna in receiving water bodies unless it is treated adequately. Due to these reasons, the treatment process to be implemented should be the least damaging to the environment. In this study, three treatment scenarios that include a UASB (upflow anaerobic sludge bed) reactor (Scenario-1), an advanced oxidation process that includes UV/H2O2 treatment (Scenario-2) and a membrane bioreactor (Scenario-3) have been studied for a meat processor's wastewater treatment plant. For these three scenarios, an environmental impact assessment was undertaken using the Fine-Kinney method. The evaluation results revealed that Scenario-2 has the smallest environmental impact value with 475. Scenario-1 has the highest total environmental impact value as 765. Scenario-3's environmental impact value is 637. According to the evaluation results, the UV/H2O2 process is the most applicable technology for wastewater treatment in Turkey's meat industry.
