【正文】 V/H2O2 降解MMTD Me 和MMTD的反應速率常數(shù)分別為( 177。s) ,因此投加質(zhì)量濃度為1mg/L 的H2O2 光催化后, 去除99%的MMTD Me 和MMTD 分別需要5 min。A. B. Isil 等將OO3 /H2OUV/O3 三種方法應用于抗生素廢水預處理〔23 〕: O3( pH 12) , O3 /UV, O3 /H2O2 ( 50 mmol /L)氧化過程在COD 及抗生素殘留物去除效果上相差無幾, 但光照條件下的O3 吸收率比無光照提高20%, 且較大幅度提高了芳香族物質(zhì)去除率及廢水的生物降解能力。高級氧化技術(shù)將難降解大分子有機物氧化成低毒或無毒的小分子物質(zhì), 改善廢水的生化性, 續(xù)以成熟的生化技術(shù)進一步降解, 可同時解決高級氧化技術(shù)運行費用高和傳統(tǒng)生化法降解難的問題, 對于抗生素廢水這類典型的廢水, 聯(lián)合處理顯得尤其有意義。超聲波—好氧生物接觸法處理含慶大霉素、鏈霉素等抗生素廢水, 200 W 輸出功率超聲波單獨處理CODCr 為6 000～8 000 mg/L 的水樣60 s, CODCr 去除率為13% ～16%。將高級氧化技術(shù)作為廢水后處理工序同樣可行。有學者提出, 對于可生化性差的抗生素廢水, 可以考慮將其分類并完全以AOPs 降解, 但就目前的研究情況而言, AOPs 全程處理廢水成本較高, 而作為廢水的預處理方式能揚長避短, 降低處理成本, 同時達到預期處理效果〔28〕。[ 參考文獻][ 1] Zwiener C, Frimmel F H.
