Wastewater in The Starch Industry
2016-10-21Starch is an important industrial raw material, in addition to food and processed food, the more widely used in textile, paper, pharmaceutical, fermentation, casting, adhesive, chemical, mechanical and drilling and other industries. At present, China's annual output of more than 300 million tons of starch.
In the starch production process, wastewater discharge is large (the average production of it starch need to be discharged 10 ~ 20m3 wastewater), and such waste water is a large number of starch, protein, carbohydrates, fats and other organic high concentration organic wastewater, such as Will not be directly discharged into the water body, will cause environmental water bodies of oxygen, so that the death of aquatic organisms suffocation, to the environment a great harm.
So, the the step of process west water is indispensable in the starch processing project.
