含酸废水处理综述

含酸废水是电镀行业生产中的主要污染物，排人市政污水管阏将严重影响城市污水处理厂的正常运行，排入外环境将使水体水质恶化。含酸废水在很多国家和地区都造成了严重的环境污染，应从清洁生产的角度考虑处理及综合利用。对当前含酸废水处理技术的应用和研究状况进行了综述，着重介绍了化学中和法、离子交换法、膜法在大气污染含酸废水处理中的应用。

Review of Acid-bearing Wastewater Treatment

Acid-bearing wastewater is the main pollutant during metallurgy production, which will severely affect the normal operation of the wastewater treatment plant when it＇s drained into the municipal sewage pipe, and results in the water quality worsening when it＇s drained into water body. In many countries and areas, acid-bearing wastewater leads to serious environmental pollution, it should be treated and utilized comprehensively based on the clean production principle. The current application and the research situations of acid-bearing wastewater treatment in the realm of environmental protection were surveyed. And the treating methods of neutralization, ion exchange and microfiltration in acid-bearing wastewater treatment were emphasized.
