The invention provides a method for producing foamed concrete by using sewage treatment plant sludge hydrolysis protein. First, with the preparation of foaming agent, sewage treatment plant sludge protein hydrolysate formula: protein hydrolysis sludge (10 ~ 96% ~ 99% DEG 21Be), preservatives (sodium benzoate or phenol) from 0.2% to 0.3%, stabilizer (carboxymethyl cellulose sodium or polyvinyl alcohol) from 1% to 3%. Foam concrete component (weight ratio): 0.6 ~ 8% cement foaming agent, 5 ~ 30%, 35 ~ 70% of fly ash, lime sand 5 ~ 50%, 4 ~ 15%, 1 ~ 1.5% gypsum, plus the components integrated 10% ~ 50% water (the total water content is 38% ~ 50%). The invention fully utilizes the sludge of the sewage treatment plant to hydrolyze protein and generates foamed concrete building materials, the production cost is low, the foaming effect is good, and the utility model is favorable for environmental protection.
