摘要：
A system and a method for treating scrubber wastewater and ballast wastewater efficiently at the same time does not require multiple treatment facilities. A wastewater treatment method includes a mixing step of mixing ballast wastewater with scrubber wastewater to make a suspended solid concentration or turbidity of the obtained wastewater mixture constant, the scrubber wastewater produced by bringing exhaust gas and scrubber washing water into contact with each other in a scrubber 10; a treatment step of adding a magnetic powder to the wastewater mixture; and a separation step of magnetically separating magnetic flocs obtained in the treatment step, as well as a wastewater treatment system including: a mixer 3 that mixes ballast wastewater with scrubber wastewater to make a suspended solid concentration or turbidity of the obtained wastewater mixture constant, the scrubber wastewater produced by bringing exhaust gas and scrubber washing water into contact with each other in a scrubber; a magnetic powder adding device 4 that adds a magnetic powder to the wastewater mixture obtained by the mixer; and a magnetic separator 5 that magnetically separates magnetic flocs obtained by the magnetic powder adding device.
