Biological and Environmental Engineering:
The method for advanced wastewater treatment without excess sludge according to the present invention comprises of conducting physical treatments and/or chemical treatments independently or concurrently to decompose sludge generated from a biological wastewater treatment process and an advanced wastewater treatment process, in which, for the physical treatment, at least one method is selected from mechanical decomposition, heating, freezing and defrosting, and ultrasonic irradiation methods and, for the chemical treatment, at least one method is selected from ozone, acid . Alkali, hydrogen peroxide, and enzyme treatment methods; and of injecting the decomposed sludge into an anaerobic/anoxic bioreactor of the biological wastewater treatment process and utilizes it as a carbon source for denitrification and phosphorus removal
