Summary:The invention discloses a modified starch production wastewater treatment method in the technical field of wastewater treatment equipment, which comprises the following steps: S1, pouring a proper amount of modified starch production wastewater into first wastewater treatment equipment, and adding a proper amount of calcium hydroxide and alum solid, so that the alum can accelerate flocculent precipitation of the modified starch production wastewater, meanwhile, calcium hydroxide solids are dissolved in water to adjust the PH value of the modified starch production wastewater, and sulfate ions and phosphate ions in the modified starch production wastewater can be changed into calcium sulfate and calcium phosphate solids to be precipitated. A proper amount of modified starch production wastewater is poured into the first wastewater treatment equipment, and a proper amount of calcium hydroxide solid is added, so that the calcium hydroxide solid is dissolved in water to adjust the PH value of the modified starch
