以贵州省六盘水地区的高铁低铝粉煤灰为吸附剂,超声辅助处理低浓度含磷废水,讨论超声是否利于粉煤灰处理含磷废水;并考察粉煤灰粒度、pH值、吸附时间、含磷废水初始浓度对粉煤灰磷去除率的影响。结果表明:适宜的超声功率,有利于吸附过程的进行;超声功率240W,在浓度5~10mg/L、pH值为8的含磷废水中投加1g粒度为180目的粉煤灰吸附2h,磷去除率可达99.7%,净化后水中磷的浓度为0.015~0.03mg/L。
Taking low aluminum fly ash of Liupanshui area of Guizhou Province as adsorbent, ultrasound-assisted treatment of low-concentration phosphorus-containing wastewater to discuss whether ultrasound is beneficial to the treatment of phosphorus-containing wastewater by fly ash; and the particle size, pH, adsorption time, Effect of Phosphorus Wastewater Initial Concentration on P Removal Rate of Fly Ash. The results showed that the suitable ultrasonic power was favorable for the adsorption process. Ultrasound power 240W, the concentration of 5 ~ 10mg / L, the pH value of 8 wastewater containing phosphorus 1g granularity 180 mesh fly ash adsorption 2h, phosphorus Removal rate of up to 99.7%, purified water phosphorus concentration of 0.015 ~ 0.03mg / L.
