When PFI Foods was initially established, the first project completed was the sewage treatment plant.
PFI Foods water separation system and sewage treatment system. The sewage treatment system adopts the latest SBR treatment method, enabling the treated water to meet the first - class discharge standard.
According to the characteristics and properties of sewage, the production sewage is planned to adopt the "physicochemical + biochemical" deep treatment method.
The physicochemical method mainly adopts the flotation method, which mainly removes a large amount of suspended solids and particulate matter in the sewage through the flotation process. Then, the effluent is further treated by hydrolysis acidification to improve the biodegradability of the sewage. Finally, the aerobic method is used to further remove pollutants and achieve the treatment effect.
