摘要
为了有效处理高校废水中的油脂和高浓度有机物,文章针对废水预处理技术的应用展开研究,采用A2/O-MBR工艺对高校中原有的一体化污水处理系统加以改造,在原有工艺的基础上增设气浮池,并根据废水的来源,制定气浮池工程改造方案加以实施,重点对废水处理效果进行实验研究与验证.根据调节池与气浮池的测试数据可以得出,通过增设气浮池,废水中的COD下降了41.2％,TP下降了 25.3％,动植物油下降了 54.5％,表明A2/O-MBR工艺具有良好的应用效果.
Abstract
In order to effectively deal with the oil and high concentration organic compounds in university wastewater,the application of wastewater pre-treatment techniques is studied.The A2/O-MBR process is used to transform the existing integrated sewage treatment system in universities.An air flotation tank is added to the original process.Based on the source of wastewater,a renovation plan for the air flotation tank is determined and implemented.And the experimental research and verification of the wastewater treatment effect have been conducted.The test data of the regulating tank and air flotation tank shows that after flowing through the air flotation tank,COD in wastewater decreased by 41.2％,TP decreased by 25.3％,and animal and vegetable oil decreased by 54.5％.This result indicates that the A2/O-MBR process has good application effects in sewage treatment.
