Abstract: A controlled-type recalcitrant high-concentration freeze-separation apparatus, includes: a condenser having therein a condenser stainless antifreeze tube formed in a cell and tube form, and a condenser copper refrigerant tube formed in a cell and tube form inside the stainless antifreeze tube to block direct contact between circulating water flowing into the condenser and the condenser copper refrigerant tube; and an evaporator having therein an evaporator stainless antifreeze tube formed in a form of a cell and tube inside, and an evaporator copper refrigerant tube formed in a cell and tube form inside the evaporator stainless antifreeze tube to block direct contact between circulating water flowing into the evaporator and the evaporator copper refrigerant tube.

Abstract: A controllable advanced decomposition equipment for industrial process-water containing non-biodegradable organics and in-organics, which is configured in multiple stages, includes: an ozone dissolving tank, a hydroxyl radical forming tank, and a gas-liquid separation tank as a unit process are configured in multiple stages. A G/L ratio is controlled by adjusting an ozone-gas amount and a circulating-water amount, thus maximizing ozone availability in the ozone dissolving tank, and then a current density is adjusted in the hydroxyl-radical forming tank to maximize the generated amount of hydroxyl radicals due to the charging of semiconductor catalyst, thus controlling the treatment efficiency of non-biodegradable process water.
