用气浮＋A／O＋深度组合工艺处理乳品生产有机废水

针对乳品行业工业废水有机物浓度较高难以处理的现状，试用气浮＋A／O＋深度组合工艺处理乳品生产有机废水。通过具体案例，介绍了工艺的原理、流程以及主要处理构筑物的设计，并列出了工程实践的数据。经过工厂半年的实际运行，设备运转正常，处理效果稳定，指标全部达到了国家《污水综合排放标准》（GB8978—1996）一级排放标准。表明该方法处理效果好、工艺流程短、技术可靠、设备先进，而且工程投资少、运行费用低、无二次污染。

The Combined Process of Air Floatation,A/O Treatmentand Advanced Treatment is Used for Organic Wastewater Treatment Dairy Production

According to the current situation that organic concentration of wastewater in dairy industry is high, which makes it difficult to treat with wastewater,the combined process of air floatation treatment, A/O treatment and advanced treatment is used for wastewater treatment in the paper. The principle, procedure and the desigh of the combined process are introducted through the concrete cases,at the same time the data of project practices are given. Actual inspection in the factories in half a year shows that the equipment runs normally and the process is operated stably, also all indexes meet the first class standard in the national Sewage Comprehensive Discharge Standard （GB8978 - 1996）. The result shows that the method is of good effect, shorter process, reliable technique, advanced equipments,less project investment, low running cost and of nonsecondary pollution.
