摘要：

研究了相同功率(400W)条件下超声波、微波分别处理制药废水的效果，结果表明：(1)在处理的初始超声波、微波均使COD有先升高后下降，最后趋于稳定的现象;就去除COD而言，在运行条件为400W时，处理制药废水的最佳时间为240s。(2)超声波、微波处理制药废水NH3-N去除率都能达到47%，开始NH3-N下降较快但随后有波动，在480s后NH₃-N分别稳定在14、6mg/L。此外,在功率400W，处理时间240s条件下，微波和超声波分别与生物接触氧化法组合处理制药废水对COD和NH₃-N去除率>60%。使用总体综合特征的假设性检验(α=0.05),两种组合处理制药废水对COD和NH₃-N的去除效果不存在显著差异。

Abstract:

The pharmaceutical wastewater treated separately by ultrasonicand microwaveunder the samepower(400W) has beenstudied. The result sshow:(1)The COD of the pharmaceutical wastewater goesupat the beginningthengoes downand finallybe comes stable. Inregard to the removal of COD, the best treatment timeis 240sunder the power (400W).(2)The removal ratio of NH₃-N of the pharmaceutical wastewater reaches47%, andthevalue of NH3- N of the pharmaceutical was tewater fall squicklyat the beginning but finally becomesstableatalevel of14, 6mg/Lapproximately. Inregardtotheremoval ofNH₃- N, thebest treatment timeis480sunderthe power(400W). Moreover, the combined processoful trasonicor microwave with biological contact oxidationapplied to the treatment of the pharmaceutical wastewater arealso studied. The removal ratio of COD and NH₃-N of the pharmaceutical wastewater disposed bythetwo combined process reaches over 60%, and the rearenodifference between the two combined process.
