Ⅱ、低压反渗透去除水中铁的卫生学评价本文探讨了低压卷式渗透去除水中铁的性能,并进行了卫生学评价。实验原水取自来水10升,用l∶1盐酸调节水pH,然后加入硫酸亚铁胺0.357克,使水含铁量在5mg/1左右。采用2×2析因设计,安排为一号水样(a_1b_1):水温13℃、pH6.5～7.5;二号水样(a_2b_1): Ⅱ. Hygienic evaluation of low pressure reverse osmosis to remove iron from water In this paper, the performance of low pressure coil infiltration to remove iron in water was discussed, and hygienic evaluation was carried out. Raw water from the experiment 10 liters of water, with l: 1 hydrochloric acid to adjust the water pH, then add ferrous sulfate 0.357 g, the amount of iron in water 5mg / 1 or so. A 2 × 2 factorial design was used to designate a water sample (a_1b_1) with a water temperature of 13 ° C and a pH value of 6.5 to 7.5. A second water sample (a_2b_1)
