Abstract: This paper is prepared to solve the problem of incomplete removal of suspended solids in beverage factory wastewater by flocculation precipitation. The research on pH adjustment and flocculant addition amount has been carried out to improve the flocculation effect，and the suspension removal rate can reach 99.17%. This method is easier and more accurate than the pre-distillation method.

Key words: beverage factory wastewater；ammonia nitrogen；flocculation precipitation；pH；suspended solids content
