| Abstract: | By studying Yi Hua PTA plant refined wastewater treatment process,analysis the processing technology, the intermediate product PT acid was recovered. The goal of cost reduction and energy conservation and emissions reduction was achieved. The specific process is step by step cooling on refining wastewater. The recycling material was treated by filtration and extraction classification process to reduce unit consumption and COD emissions. |
