在水处理技术中,化学法一直居于主导地位。化学处理用的水处理剂,其发展水平是水处理技术水平的重要标志之一。在世界性水源短缺、环境污染日趋严重的今天,水处理剂的发展日益受到世界各国,尤其是工业发达国家的普遍重视,其在精细化工领域中的地位不断提高。1977年,在美国的十类精细化学品(涂料、表面活性剂、胶粘剂、水处理剂、食品添加剂、医药、饲料添加剂、染料、有机颜料和油田化学品)的销售额中,水处理剂位居第4,仅次于涂料、表面活性剂和胶粘剂。水处理剂在我国的发展则方兴未艾。 当前,我国正处于深化改革、开放的发展时期。在考虑或规划我国水处理剂工业发展战略目标时,我们必须适应新形势的需要,进一步更新观念,解放思想,努力把我国的水处理剂工业引
In the water treatment technology, the chemical method has been dominating. The level of water treatment agent used for chemical treatment is one of the important signs of water treatment technology. With the shortage of global water resources and increasingly serious environmental pollution, the development of water treatment agents has been increasingly valued by all countries in the world, especially industrialized countries, and its position in the field of fine chemicals has been continuously improved. In 1977, water treatment agents were used in sales of ten types of fine chemicals (coatings, surfactants, adhesives, water treatment agents, food additives, pharmaceuticals, feed additives, dyes, organic pigments, and oilfield chemicals) in the United States. Ranked fourth, second only to coatings, surfactants and adhesives. The development of water treatment agents in our country is in the ascendant. At present, China is in a period of deepening reform and opening up. When considering or planning the development strategic objectives of China’s water treatment agent industry, we must adapt to the needs of the new situation, further update ideas, emancipate the mind, and strive to introduce China’s water treatment agent industry.
