[0002] At present, starch is an important food additive and industrial raw material, and a large amount of starch wastewater is produced during starch processing. Starch wastewater contains high concentrations of organic matter and suspended solids, and has strong acidity and alkalinity, causing serious pollution to the environment. Therefore, the reasonable treatment of starch wastewater has become an environmental issue that cannot be ignored in the development of the starch industry. Starch wastewater mainly has the following characteristics:

[0003] High concentration of organic matter: Starch wastewater contains a large amount of starch molecules and other organic matter, and its pollutant concentration is generally high.

It is impossible to neutralize the wastewater and adjust the acid and alkali to make the wastewater solution mix and react, resulting in the inability to completely remove pollutants, and the inability to completely separate biological waste residues from wastewater, and unable to recycle and utilize it, seriously polluting the environment.
