A valuable resource recovery system includes an engineered powder supply unit that supplies an engineered powder into drainage water (the engineered powder can adsorb a valuable resource and can be desorbed from the engineered powder), an agitation unit that agitates the drainage water supplied with the engineered powder, an engineered powder separation unit that separates the engineered powder from the drainage water agitated by the agitation unit, an engineered powder collection unit that collects the engineered powder separated by the engineered powder separation unit, and a desorption-recycle unit that desorbs the valuable resource from the engineered powder collected by the engineered powder collection unit to recycle the engineered powder and the valuable resource. According to the system, the valuable resource can be desorbed from the engineered powder and then recycled.

Valuable resource recovery system and operation method thereof

A water treatment system comprises: an oil removal apparatus including a fixed-bed reactor configured to hold an adsorption particles by use of a magnetic unit, the adsorption particles each including a base material containing magnetite, the adsorption particles configured to adsorb oil included in to-be-treated water; a pretreatment apparatus configured to recover the oil from the adsorption particles sent from the oil removal apparatus; and a thermal energy generating apparatus configured to obtain thermal energy from the oil recovered by the pretreatment apparatus.
