Treatment method of sugar production wastewater

The invention provides a treatment method of sugar production wastewater, which is realized by preparing a carrier and treating the sugar production wastewater, wherein the preparation of the carrier is realized by drying bagasse, crushing and screening; and the treatment of the sugar production wastewater comprises the following steps: adopting an internal-circulating three-phase fluidized bed reactor, forming a membrane firstly to start, and then adopting a batched sequencing batch reactor (SBR) running operation process for treatment. According to the treatment method, the residue which is the bagasse produced in a sugar production process is used to treat the sugar production wastewater; the bagasse is used as the membrane forming carrier, so that the wastewater treatment cost is low; the treatment method is not only capable of changing the waste into things of value and utilizing the bagasse, but also capable of realizing waste control by waste and environmental purification. According to the treatment m
