PROBLEM TO BE SOLVED: To provide a wastewater treatment method and a wastewater treatment apparatus capable of economically recovering recovered water with a low remaining TOC concentration in the wastewater treatment containing chemical components.SOLUTION: In the wastewater treatment method and the wastewater treatment apparatus, among the wastewater discharged from a production process, the wastewater containing high-concentration organic chemicals is introduced into a high-concentration wastewater treatment line, and the wastewater containing low-concentration organic chemicals is introduced into a low-concentration wastewater treatment line. In the high-concentration wastewater treatment line, a biological treatment process treating the organic matters in the wastewater by means of micro-organism, and a physicochemically oxidative decomposition process are carried out. In the low-concentration wastewater treatment line, a biological treatment process treating the biologically untreated wastewater by means of micro-organism is carried out. |
