The invention provides a biological fermentation pretreatment method for high-concentration organic wastewater and application thereof, which can solve the technical problems of high equipment investment and operation cost, high energy consumption and easy secondary pollution of the existing physicochemical treatment process. A biological fermentation pretreatment method for high-concentration organic wastewater can reduce or avoid using physicochemical treatment processes such as iron-carbon micro-electrolysis, Fenton, evaporation concentration and the like, and greatly reduce the wastewater treatment cost, and comprises the following steps: s1 biological fermentation pretreatmentStarting; s2 biological fermentation pretreatment debugging operation; and the S3 biological fermentation pretreatment system runs stably. The invention changes COD by setting reasonable strain proportion, starting and running conditions and by means of strain fermentation cr The physicochemical property of high-concentration organic wastewater can reach tens of thousands or even tens of thousands, and the COD of the wastewater is reduced cr TN, and the wastewater is changed into 'fermentation-like wastewater' with low toxicity and easy biochemistry, thereby reducing the subsequent treatment cost of the wastewater and not generating secondary pollution. |
