Treatment of starch wastewater treatment equipment author of the article: Food industry requires a lot of clean water to produce food in our daily life needs, at the same time, the production process will produce large amounts of waste water, it would need to use starch production wastewater The treatment method is professionally treated. The following is an introduction to the treatment method of starch production wastewater treatment equipment. 1. Preliminary filtration and sedimentation. First, the food industry wastewater flows through multiple grids, and then discharged into the sedimentation tank, flocculating agent is added for flocculation, and air is blown, and then sedimentation is performed to obtain the supernatant of the industrial wastewater. 2. Ultraviolet ray sterilization and pH adjustment. Discharge the industrial wastewater supernatant described in step A into the acid-base adjustment tank, first sterilize and disinfect with ultraviolet rays to remove peculiar smell, and then adjust the pH to 5.5-7.5 with alkali. That is, industrial wastewater after adjusting the pH value is obtained. 3. Bacterial decomposition and activated carbon filtration. The industrial wastewater after adjusting the pH value in step B is first passed into the anaerobic aeration tank, and the macromolecular carbon source material and macromolecular nitrogen source material are decomposed by anaerobic bacteria. Then enter the aerobic tank, use aerobic bacteria to decompose the small molecule carbon source material and small molecule nitrogen source material in the wastewater, and then use the facultative membrane bioreactor to treat the wastewater from the aerobic tank, and then add the reducing agent, using The activated carbon filtration process performs filtration treatment and then sedimentation treatment to obtain filtered industrial wastewater. 4. Membrane filtration first uses the security filtration process to filter the industrial wastewater described in step C, then uses the microfiltration membrane filtration process for filtration treatment, and then uses the ultrafiltration membrane filtration process for filtration treatment, using reverse osmosis The membrane filtration process performs filtration treatment to obtain discharge water that meets environmental protection standards. The above is an introduction to the treatment methods of starch production wastewater treatment equipment. I hope it will be helpful to you.
