METHOD FOR TREATING WASTEWATER

摘要

The present invention relates to a wastewater treatment method. According to the wastewater treatment method of the present invention, wastewater containing highly concentrated impurities such as non-degradable organic materials generated from various organic chemical processes and salts can be purified with low-energy and simple processes. Also, supernatant separated by the wastewater treatment method of the present invention can be used as fuel steam for other processes and thus reduces total flux of discharged wastewater while saving more energy and reducing burden of microorganism decomposition treatment without acid treatment or using an extraction agent.
