Na2BO3 and Na2SO4 were used as coagulant,Fe2(SO4)3 was used as sediment reagent. When the dosage of Na2BO3 was 20 mL,Na2SO4 was 20 mL,Fe2(SO4)3 was 3 mL,pH was 7,deposition time was 4 h, the CODCr removal rate can reach 89.6%.

• 结果表明:投加饱和硼砂溶液20 mL、饱和硫酸钠溶液20 mL、饱和硫酸铁溶液3 mL、pH为7、静置时间为4 h；可使胶粘剂废水的CODCr从6 800 mg/L；下降到707 mg/L；去除率可达到89.；6%25。
