摘要
从某污水处理厂技术改造失败的教训入手 ,深入分析了曝气设备各指标间的关系 ,区分了设备的效能指标与规格指标 ,探讨了曝气设备选择上的困惑 ,估算了曝气设备选择不当可能造成的经济损失 ,提出了如下观点 :动力效率是曝气设备唯一的效能指标 ,应大力推广动力效率高的设备 ,坚决淘汰动力效率低的设备 ;充氧能力和氧转移效率是规格指标 ;在评价曝气设备性能、选择曝气设备类型时 。
By drawing a lesson from the failure of technology reforming of a sewerage treatment factory,the relations between indexes of aerators are analyzed,the differences of indexes for efficacy and specifications of aerators are distinguished, the perplexity for selection of aerator is studied,economical losses as a result of improper selection of aerator are estimated,and following viewpoints are given:power efficiency is the only efficacy index for aerator, aerators with high power efficiency should be popularized with major efforts,but those with low power efficiency should be die out;oxygenation capacity and oxygen transfer efficiency are specification indexes,when the function of aerator is appraised or aerator is selected,oxygen transfer efficiency should not be taken into account.
