气浮＋A/O＋接触氧化＋转盘过滤法处理饮料废水的应用研究

针对饮料废水可生化性较好的特点,可采用气浮＋A/O＋接触氧化＋转盘过滤组合工艺处理饮料废水。采用气浮工艺物化处理单元,可有效去除大部分不溶性有机物和悬浮物,实现大分子链断裂转化为小分子,采用A/O＋生物接触氧化生化处理,可使水质达到一级B标,采用转盘过滤深度处理总氮和总磷,出水达到一级A标。通过云南某饮料企业的实践,该方法可高效处理饮料废水。

A Study of Air Floatation- A/O -Biological Contact Oxidation- Rotary Disc Filter Processes for the Treatment of Beverage Wastewater

In light of better biodegradability of beverage wastewater, the integrated technology of air floatation ＋ A/O ＋ biological contact oxidation ＋ rotary disk filtration could be applied tO treat the beverage wastewater. By applying physical and chemical treatment technology of air floatation, most insoluble organic matter and SS could be removed, while the macromolecule chain could be broken into the small molecules. By applying A/O ＋ biological contact oxidation technology, the outflow water quality after the treatment could reach Standard B of Grade I of National Comprehensive Wastewater Discharge Standard. By applying rotary disk filtration technology to deeply treat TN and TP, the outflow water quality could reach Standard A of Grade I. The application of the technology in one beverage enterprise in Yunnan proves to be highly effective.
