Desulfurization wastewater treatment system and method

The invention provides a desulfurization wastewater treatment system and method. The desulfurization wastewater is treated by adopting aeration, ultrasonic wave, electric flocculation and non-water-soluble polymer chloride ion removal special resin technologies, organic sulfur is not required to be added to remove heavy metals, and two flocculants, namely PAC and PAM, are not required to be added, so that secondary pollution caused by the organic sulfur, the polymer flocculant and the like is reduced, and the treatment cost of chemical treatment of the desulfurization wastewater is reduced. 本发明提供了一种脱硫废水处理系统及方法。通过采用曝气、超声波、电絮凝和非水溶性高分子除氯离子专用树脂技术处理脱硫废水，不需要加入有机硫除重金属、也不需要加入PAC和PAM二种絮凝剂，减少了有机硫、高分子絮凝剂等带来的二次污染，降低了化学处理脱硫废水处理费用。
