Treatment method of thiourea-containing chemical organic wastewater

The invention belongs to the technical field of water treatment, and relates to a treatment method of thiourea-containing chemical organic wastewater. The method is used for treating thiourea-containing chemical organic wastewater. The wastewater is subjected to distillation treatment, distillation effluent is adjusted to be alkaline after distillation, then alkaline hydrolysis treatment is carried out, the pH of effluentalk obtained after alkaline hydrolysis treatment is adjusted to be 6-8, then electric flocculation treatment is carried out, and effluent obtained after electric flocculationtreatment is subjected to biochemical treatment and then discharged. According to the method, organic thiourea and sulfide in the wastewater can be reasonably and effectively removed, the treated effluent can enter a biochemical system to be treated, the final effluent reaches the discharge standard of a park, and the problems of low treatment rate and poor treatment effect in the prior art are solved. 本发明属于水处理技术领域，涉及一种含硫
