| Abstract: |
| A large amount of sludge is produced in the wastewater treatment of vegetable oil processing plants， and reducing the sludge yield can not only reduce the cost, but also reduce the risk of environmental protection.Combined with practical application experience, the characteristics of wastewater produced in vegetable oil processing was analyzed, and the various aspects of sludge production were analyzed by describing the characteristics of wastewater treatment process. The sludge yield could be successfully controlled at a low level and more waste oils/soaps could be recovered by collecting the available components in the wastewater through using suitable demulsifier, reducing the dosing amount, adopting a suitable biochemical treatment process and selecting an efficient sludge dehydration equipment. |
