The basic oxygen steel-making process is another important technical revolution following the Bessemer process and the Thomas process. It is now playing a vital part in the steel industry in countries like West European countries, Japan, etc. After taking stock of the present steel production and modern development in several leading countries and after comparing various kinds of oxygen steel-making processes, the author points out that the basic oxygen steel-making process is the main trend in steel production from now on. In his thesis, the author compares by illustrations the basic oxygen process and the open-hearth process in the following respectsthe methods of operation, the suitability of raw materials, the total yield, production costs, and the investments in basic construction. He also points out with emphasis that the basic oxygen process surpasses the open-hearth process in the kinds of products and their quality. He takes into considerations of the resources and the conditions of production of our country, and gives his personal opinion at the end of his thesis: The question of making immediate use of oxygen is on the programme today. The rapid development of oxygen steel-making should become one of the significant measures to push forward the production of the whole industry.

碱性氧气轉炉炼鋼法是继貝士麦炼鋼法和托馬斯炼鋼法之后又一次重要的技术革命,已經在若干国家如西欧国家、日本等炼鋼工业中起着巨大的作用。作者从世界上几个主要产鋼国家现时生产和发展的形势,在比較了不同类型的氧气炼鋼方法后指出:碱性氧气轉炉冶炼是今后炼鋼的一个主要发展方向。文中作者用实例就碱性氧气轉炉的操作方法、原料的适应性、金属收得率、产品成本以及基建投资等方面与平炉作了对比,并着重指出:碱性氧气轉炉鋼在品种和质量方面与平炉鋼相比較,实有过之而无不及。作者結合我国资源和生产情况,在文末提出个人意見,认为:氧气在我国冶金工业中的加速使用已經提到日程上来。加速发展氧气炼鋼应成为进一步推动整个工业生产的重大措施之一。

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。
