Patent ID: 8425768

Claim:
A wastewater treatment system comprising: an oxidation reactor configured to receive a flow of wastewater containing metals and cyanide from a wastewater producing process, the oxidation reactor further configured to oxidize a chemical associated with the flow of wastewater with an oxidation agent, the oxidation reactor further including: at least one inlet line carrying the wastewater containing metals and cyanide from the wastewater producing process; a supply of acid and a supply of hypochlorite connected to the inlet line for injecting the acid and hypochlorite into the at least one inlet line; and at least one reaction member configured to pressurize at least a portion of the oxidation reactor and positioned within the oxidation reactor, the at least one reactor member including a coiled tube positioned in the oxidation reactor with one end connected to the at least one inlet line and the other end positioned proximate a bottom of the oxidation reactor; a source of pressurized air; an air inlet port in the bottom of the oxidation reactor and connected to said source of pressurized air for injecting air into the oxidation reactor; an exhaust port in the top of the oxidation reactor for directing gases to a scrubber; an outlet port for cyanide free water in a sidewall of the oxidation reactor; and at least one resin tank containing an ion exchange resin configured to target a particular metal, the at least one resin tank configured to receive the cyanide free water from the outlet port of the oxidation reactor.
