摘要
Abstract
In this paper, bentonite was used in treatment of low concentration waste water from pulp & paper mills. The bentonite was used as adsorption agent while the PASC was used as flocculation agent. At the optimum conditions: dosage of PASC 400 mg/L, dosage of bentonite 500 mg/L, reaction temperature 30℃ , 300 rpm stirring and absorption 20 min, CODCr decreases from 230 mg/L to 90 mg/L, the removal rate is 60.9% , the removal rate of chroma is 41.4%. Indicating that it meets the new discharge standards at a relatively low cost of investment and operation.关键词
