Based on analyzing al kinds of the disposal technology characters and application on acid waste water, the article approves that the physico-chemical treatment technology could effectively dispose al kinds of acid waste water. The physico-chemical treatment technology had some advantages such as wide adaptability on waste water, high heavy metal removal efficiency, and so on. So it can be used widely in the waste water disposal projects. According to the application of waste water disposal projects, the article points out several shortcomings need to be solved, such as the high disposal cost, the hard process control.% 通过分析各种含酸废水处理技术的特点和工程应用，指出利用物化技术能够有效处理各种含酸废水，具有废水适应性广、重金属去除效率高等优点，适合工程应用；物化技术在实际工程应用中，还存在处理成本高、工艺控制点不易控制等不足，需进一步研究加以克服。
