Project description: the construction scale requires a total sewage treatment capacity of 80 tons/day, including 30 tons/day of production wastewater and 50 tons/day of domestic wastewater.

The treatment process of "grille grease trap + regulating tank + hydrolytic acidizing tank + aerobic contact oxidation tank + secondary sedimentation tank + sludge concentration tank" was adopted.

The final discharge of wastewater is superior to the level 3 discharge standard of xiamen municipal water pollutant discharge standard (db35-322-2011) and basically reaches the level 1 discharge standard
