Abstract: A wastewater treatment system may use recycle water to apply an anaerobic ammonium oxidation (ANAMMOX) process to a water treatment process (mainstream treatment process) and to stably supply nitrite required for an ANAMMOX. By applying the ANAMMOX process, nitrogen and phosphorus may be simultaneously treated in the water treatment process, and recycle water may be used as a source of nitrite for ANAMMOX, thereby reducing wastewater treatment costs and pollutant loading.

Abstract: The present technique discloses a buck-boost converter. According to a detailed example of the present invention, a number of switching elements of a buck-boost converter is reduced compared with a conventional buck-boost converter, and thereby a buck mode and a boost mode are performed with reduced overall conduction loss and switching loss. In addition, a buck-boost converter that is capable of stepping up and down an input voltage over a wide range using a single control device, that has a simple structure, that has inexpensive manufacturing costs, and that has a high circuit integration density can be realized by configuring the buck-boost converter to connect a two-phase interleaving boost converter unit to a single-phase buck converter unit.
