Treatment Technology of Waste Acid and Waste Water in Chemical Industry Produce

The environmental pollution of waste acid and waste water is very big, The front treatment discharging is very important. The significance and treatment methods of waste acid and waste water were summarized in this arti- cal. And various method have been Introduced that detailedly. The treatment method of waste acid include concen- trate and extraction and oxidize and crystallize. The concentrate include high temperature concentrate and low temper- ature concentrate. The treatment method of waste water include physics treatment methods and chemistry treatment methods and biology treatment methods and biology contacts oxide treatment methods. Actuality of development of waste acid and waste water treatment technology were introduced, and primary directions in current research were put- ted forward.
