摘　　要：以过氧化氢为氧化剂、聚二甲基二烯丙基氯化铵(PDM)为混凝剂对高含硫废水进行控制氧化处理,考察了混凝强化机制对脱硫效果的影响。结果表明,在PDM投加质量浓度为1.0 mg/L,初始p H为6,过氧化氢投加量为9 m L/L,反应时间为15 min的条件下,混凝强化体系中硫化物去除率达99.09%,单质硫产量为1 588.5 mg/L,较普通反应体系分别提高了1%和14%;SO_4^(2-)产量为209.69 mg/L,较普通体系降低了8%。Using peroxide as oxidant,and poly dimethyl diallyl ammonium chloride(PDM)as coagulant,controlled oxidation treatment has been used on the highly concentrated sulfur-bearing wastewater. The influences of coagulation enhancement mechanism on desulfurization effect are investigated. The results show that under the following conditions the mass concentration of PDM added is 1.0 mg/L,initial p H 6,peroxide dosage 9 m L/L and reaction time15 min,the sulfide removing rate in the coagulation enhancement system reaches 99.09%,and elemental sulfur output is 1 588.5 mg/L,compared with ordinary systems,increasing by 1% and 14%,respectively. The SO42-output is 209.69 mg/L,compared with ordinary systems,decreasing by 8%.
