摘　　要：为降低船舶油污水处理成本,提升船舶油污水处理效率,采用次氯酸钠开展船舶油污水处理试验研究。以上海某船舶污水处理厂的油污水样品为试验对象,采用次氯酸钠氧化法,通过控制次氯酸钠的投加量和投加次数,考察不同情况对污水中COD去除率的影响,得到预氧化处理船舶油污水过程中较优的投药方式。结果表明,当总反应时间和总投加量相同时,相较于采用单次投加次氯酸钠的方式,采用分多次投加次氯酸钠的方式能取得更好的COD处理效果。The experiment is carried out to develop low cost and high efficiency ship oily wastewater treatment technology.The oily wastewater sample for the experiment is taken from a ship sewage treatment plant.The sodium hypochlorite oxidation method is used to treat the sample and the COD removal rate is observed to see the effects of different dosage-dosing time combination of sodium hypochlorite and to find suitable combination.It is seen that for the given reaction time and dosage,divided dosing gives a better result than at one-go.
