Generally, acidic wastewater is neutralized by adding alkali, and alkaline wastewater is neutralized by adding acid. Where conditions permit, acid-base wastewater can also be used for neutralization. After pH adjustment, the wastewater needs to be pretreated to remove SS and oily substances, such as using air flotation to remove oil, coagulation and sedimentation to remove suspended solids and some organic …
