description The invention provides a method for comprehensively treating and utilizing cassava vinasse waste water and industrial sludge. The method includes: pumping original cassava vinasse waste water into an anaerobic fermentation tank to perform whole-tank high-temperature anaerobic treatment so as to produce biogas; concentrating sludge discharged by the anaerobic fermentation tank, then delivering into a plate-and-frame filter press, and filtering with the plate-and-frame filter press to obtain anaerobic sludge and filtered clear liquid; using a precision filter to perform multistage purification on the filtered clear liquid to obtain first-level plain water and concentrated discharge water, processing the first-level plain water with a membrane biological processing device to obtain second-level plain water which can reach the indexes of production water, and recycling the plain water; mixing the obtained concentrated discharge water and anaerobic sludge with other industrial sludge, dewatering with a dewatering
