    This paper first discusses the effects of water pollution, and explains that different social systems and different political lines will produce different results on environmental control. Ozonation is proposed as a method of advanced treatment of oil refinery wastewater to control pollution. Laboratory experiments have been performed to find out the degree of purification obtained from ozonation and the relations between the various factors concerned. Experiments consist of treating the wastewater in static and flowing conditions. Based on the static state experiments the effluents from the aeration tanks and the flotation tanks of the wastewater treatment plant of Tungfanhung oil refinery have been treated with ozone in single-stage columns and multi-stage columns at different contact depths and different contact periods, by using various dosages of ozone to obtain the best degree of purification under the conditions of experiments. The results of experiments show that ozonation as a tertiary treatment method for oil refinery wastewater gives very satisfactory results on the main pollution parameters: such as phenol, oil, sulfides, color, C O. D., etc., and can be used as an effective method for controlling water pollution. Ozonation of effluents from flotation tanks without biological treatment also gives quite satisfactory results showing the feasibility of using physical/chemical methods of treatment for oil refinery wastewater instead of the biological methods.

    本文首先讨论了水污染造成的危害,并说明不同的社会制度和不同的路线对污染的控制会产生不同的结果。然后提出臭氧氧化法作为炼油厂废水深度处理、控制污染的方法。为了探求臭氧氧化法处理炼油厂废水的规律和效果,我们进行了试验研究,包括静态试验和动态试验两部分。在静态试验的基础上,对东方红炼油厂污水处理厂的曝气池和浮选池出水进行了单级和多级接触反应柱在不同接触柱高度、不同接触时间下采用不同的臭氧投加量以取得试验条件下的最佳处理效果。试验结果表明,臭氧氧化法作为炼油厂废水的三级处理,对炼油废水的主要水质指标:酚、油、硫、色、化学需氧量等都有很好的处理效果,是控制污染的有效方法。不经生物处理而用臭氧氧化法处理浮选池出水,也有较好的处理效果,说明采用物理、化学方法取代生物处理方法的可能性。

    The procedure and accuracy of the methods of ammonia nitrogen determination in wastewater with gas-sensing electrode and air-gas electrode were studied. In the procedure, the sample needs generally no pre-treatment and can be determined directly. The concentration of ammonia nitrogen should be in the range of 0.2~200mg/1 as other selective electrode methods, these methods are rapid. simple and accurate.

    研究了用气敏电极和气隙电极测定污水氨氮的条件和正确度。测定时,水样一般无需前处理,可直接测定。氨氮浓度应在0.2~200毫克/升范围内,同一般选择性电极法一样,有快速、简单和正确等优点。
