description The invention provides a dedicated nutritional agent for biological treatment of sludge and a production method thereof. The raw materials for production of the nutritional agent comprise sulfur powder, sodium thiosulfate pentahydrate, ferrous sulfate heptahydrate, vitamins, trace elements, carbon source substances, ammonium sodium phosphate tetrahydrate, dipotassium hydrogen phosphate, calcium chloride, magnesium sulfate heptahydrate, surfactant tween and biomass auxiliary materials. The dedicated nutritional agent is favorable for absorption of microbes and helpful to quick colonization and role playing of the microbes, effectively improves microbial activity in biological treatment of sludge and improves the dehydration property and heavy metal removal rate of sludge. When applied to sludge treatment, the nutritional agent is quantificationally put into a sludge treatment facility by using a pump, and after pressure filtration of the treated sludge, the water ratio of a sludge cake can be lowered to below
