PROBLEM TO BE SOLVED: To provide a practical drain treatment equipment which performs oxidation decomposition treatment of a water pollution-prone organic compound included in the drain such as return water from a water purification plant and water discharged from a sewage disposal plant, by using an oxidizing agent. SOLUTION: The drain treatment equipment is equipped with an oxidation reactor 4 in which the oxidizing agent is mixed in the drain to be treated and the oxidizing agent is decomposed to generate an active oxidation component, and the water pollution-prone organic compound in the drain is subjected to oxidation decomposition by the oxidation component, wherein the oxidation reactor 4 is provided with a flow passage through which the drain mixed with the oxidizing agent is caused to flow, and the interval of the wall surfaces opposing to each other of the flow passage is set to 1 to 10 mm.
