铝加工行业热处理废水处理工艺研究

Research on Heat Treatment Waste Water in Aluminum Processing Industry

铝加工行业热处理废水COD浓度较高、成分复杂以及生物降解性差等特点成为水处理中比较头疼的问题。近年来对于高端铝材冷却液选取越来越受到重视,同时产生的废水产量也日益增加,处理难度也随之加大,所造成的环境污染问题日益严重。因此寻找一种可行的方法处理热处理废水已迫在眉睫。本文综述了铝加工行业热处理废水处理技术及研究进展。

The characteristics of high COD concentration, complex composition and poor biodegradability of heat treatment waste water in aluminum processing industry have become a headache problem in water treatment. In recent years, more and more attention has been paid to the selection of high-end aluminum coolant. At the same time, the production of waste water is increasing, and the difficulty of treatment is also increasing, so that the environmental pollution caused by this process is becoming increasingly serious. Therefore, it is urgent to find a feasible method to treat heat treatment waste water. In this paper, the treatment technology and research progress of heat treatment waste water in aluminum processing industry are summarized.
