- Abstract:
- In light of the new discharge standard being implemented, the analysis was conducted on the issues related to the low treatment capacity and effectiveness of the wastewater treatment plant in Jintang County Edible Fungi Industrial Park. Based on the characteristics of influent quantity and quality of the wastewater treatment plant, the primary treatment process for the renovation and expansion project consisted of accident regulation tank, hydrolytic acidification tank, AAO/A/MBR biochemical tank, ozone advanced oxidation tank and contact disinfection tank. This combined process was designed to enhance the removal efficiency of refractory organic matter, chromaticity, total phosphorus (TP), total nitrogen (TN), and suspended solids (SS) from the wastewater. The operational results indicated that the process was functioning optimally, with stable effluent quality. The removal efficiencies of SS, TP, COD, NH3-N, BOD5, and TN achieved 96.8%, 93.7%, 94.3%, 97.5%, 96.5%, and 80.3% respectively, thereby ensuring that the effluent quality met the limits set forth in the project EIA approval. Consequently, there was a significant reduction in the pollution load of the receiving water.
