摘　　要：以微污染水库水为原水 ,采用臭氧、过氧化氢、高锰酸钾、紫外线及其不同组合作为预氧化剂 ,进行了预氧化除藻的中试研究。试验结果表明 ,预氧化能够明显提高水中藻类的去除率 ,这些预氧化方法都可达到 90 %以上的除藻率。其中以紫外线对藻类的去除率最高 ,可达 97.8% ,但紫外线在生产上的应用受到限制 ;而单独使用臭氧时除藻效果相对较差。实际应用中预氧化除藻可采用臭氧 +过氧化氢联合方案 。A pre-oxidation pilot-plant composed of ozonization, H202, potassium permanganate,UV-radiation and their combination as per-oxidation is conducted to research experimentally the effect onthe algae removal of raw water taken from a slightly polluted surface reservoir. The research resultsshow that by light of pre-oxidation the overall algae removal exceeded 90 %, evidently improved. The highest removal rate (97.8%) can be obtained with UV-radiation pre-oxidation, but unfortunately this method is limited in practical use. Lowest removal is gained with ozone only. It is suggested that O 3 +H 2O 2, or potassium permanganate if enough reaction time can be given, might be suitable for algae removal in practice.
