水解酸化/改良A^2O工艺在工业污水处理厂中的应用

Application of Hydrolysis Acidification and Improved A^2O Process in Industrial Wastewater Treatment Plant

针对工业园区产生的化工、生物、皮革、食品等工业废水和园区企业职工及居民生活污水混合水质,选取水量水质调节+水解酸化+改良A^2O工艺,同时辅以细格栅、曝气沉砂预处理和高效沉淀、精密过滤深度处理,可使尾水水质达到《城镇污水处理厂污染物排放标准》(GB18918—2002)一级A标准,可改善工业园区水环境,提高水资源利用率。

Based on the mixed water quality of industrial wastewater, such as chemical, biological, leather, food and other industrial sewage from industrial parks, and the sewage of the industrial parks and residents in the industrial park, the combination treatment process of water quality regulation ＋ hydrolytic acidification ＋ improved A2O process was adopted. And meanwhile, fine grille, aeration pretreatment for sand removal, efficient settling, and advance treatment with precision filtration. The fi- nal effluent standard of pollutants met the first level A criteria specified in the Discharge Standard of Pol- lutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The project improved the water environment and the utilization of water resources.
