摘　　要：由于我国染料及中间体行业近三十年来发展迅猛,而染料企业大多数是小型厂,染料品种繁多,在化工系统中,这一行业目前几乎是污染最严重、污染面最大、治理最差的。同时,一些发达国家把污染重、难治理的产品关停,转向发展中国家生产,染料中间体便是其中之一。所以我国大量的小型乡镇企业治理难度就更大了。不同染料生产原料、工艺过程不同,所排“三废”即有共同的特性,又有各自特点,因此需要针对各自的不同分别处理。本文从废气、有机废液和废渣、废水三方面详细叙述了工业上常用的治理方法及适用条件。并例举了几类排放量较大的废水的治理方法。As a result the rapid development of China's dyes and intermediates industry in the past 20 years, the small scale of a major of the dye plants and the numerous varieties of dyes, the pollution of this industryis almost the most serious with the largest polluted area and the most unsatisfactory control in the chemicalsystem. Meanwhile some developed countries have stopped the production of products of serious pollution which is difficult to control and produce them in the developing countries. Dye intermediates are one of these products. Pollution control becomes more difficult in small scale township enterprises in China. As different dyes need different raw materials and different processes, discharged three wastes have both same properties and different properties. Therefore it is necessary to control "three wastes' separately based on different properties.This article describes clearly control methods and its applicable conditions from three aspects of waste gases, organic waste liquids and waste residues and waste water, and gives some examples of control methods of waste water with larger discharge volume.
