【摘要】 试验研究了采用水解酸化-接触氧化工艺对某医院污水进行处理,结果表明出水水质达到《污水综合排放标准》(GB8978-1996)一级标准,并获得了相关设计参数。水解酸化段HRT为4h;接触氧化段容积负荷为4.50kgCODm3·d,HRT大于2h、气水比在8∶1以上。更多还原

【Abstract】 Hydrolysis-contact oxidation process was researched into hospital wastewater treatment. The result indicated that outflow quality reached Ⅰ-class criteria specified in Integrated Wastewater Discharge Standard(GB8978-1996), and the following parameters for design were obtained. HRT of hydrolysis process was 4h; volumetric loading, HRT and gas-water ratio of contact oxidation process were, respectively, 4.50kgCOD/m3·d, above 2h and more than 8∶1.更多还原
