摘　　要：医废焚烧含汞废水处理难度大、排放标准严格,本文通过研究混凝沉淀法和离子交换法的组合技术,确定了最佳的反应pH值为10,硫化钠投加量为10 mg/L,重捕剂的最佳投加量为50 mg/L,沉淀反应时间为70 min,树脂选用漂莱特MTS9200树脂,过滤流速为5 BV/h,树脂前增加石英砂和活性炭过滤器,废水温度保持在60℃以内,进树脂的pH保持在弱酸性,并工程应用于医废焚烧废水处理,寻找出一种医废焚烧含汞废水处理要求的工艺技术路线。The treatment of mercury-containing wastewater from medical waste incineration is challenging,and discharge standards are stringent.This study explores a combined technique of coagulation precipitation and ion exchange,determining an optimal pH of 10,a sodium sulfide dosage of 10 mg/L,an optimal heavy capture agent dosage of 50 mg/L,and a precipitation reaction time of 70 minutes.The resin used is Puromet MTS9200,with a filtration flow rate of 5 BV/h.The process includes quartz sand and activated carbon filters before the resin,maintaining the wastewater temperature below 60℃,and ensuring the resin's pH remains slightly acidic.This approach has been applied in the treatment of medical waste incineration wastewater,identifying a suitable process technology for mercury-containing wastewater treatment.
