有机磷农药废水的处理目前大多采用生化法，但是处理后的废水中有机磷的含量仍远远高于国家关于废水的排放标准．近年来，利用半导体粉末作为光催化剂降解有机污染物的研究已有许多报道［１，２］．文献［３－５］报道了利用光催化剂的悬浮体系降解有机磷化合物的研究，结... At present, most biochemical methods are used to treat organophosphorus pesticide wastewater, but the content of organophosphorus in the treated wastewater is still far higher than the national standard on wastewater discharge. In recent years, the use of semiconductor powder as a photocatalyst degradation of organic pollutants have been many reports [1,2]. Literature [3-5] reported the use of photocatalyst suspension system degradation of organic phosphorus compounds, ...
