摘 要: | 通过实验考察了聚丙烯疏水膜对低浓度氨氮废水的单级氨氮脱除率,研究了废水中的盐、钙离子和有机物等对疏水膜脱氨能力的影响。结果表明,聚丙烯疏水膜对低浓度氨氮废水的单级氨氮脱除率为50%~60%,废水中的盐分会对疏水膜的脱氨效率产生不利影响,钙离子和有机物短期内对疏水膜的脱氨效率影响不大。

Abstract: | Through experiments,the single-stage removing rate of NH3-N from low-concentration NH3-N wastewater by polypropylene hydrophobic membrane has been investigated. The influences of salt,calcium ions,organism,etc. on the removing capacity of hydrophobic membrane for ammonia are studied. The results show that the single-stage removing rate of NH3-N from low-concentration NH3-N wastewater by polypropylene hydrophobic membrane is 50%-60% and salinity in the wastewater has disadvantageous influences on the removing capacity of hydrophobic membrane for ammonia. Calcium ions and organism have little influence on the removing capacity of hydrophobic membrane for ammonia in a short time. |
