空心砖对废水中污染物吸附能力的研究

如何处理废水中的各种污染物，成为当前的一大课题。本文主要介绍了水处理方法中的以氨氮、化学需氧量、总氮、总磷为被测污染因子，树脂、空心砖粉、粉煤灰、活性炭为吸附剂，采用物理吸附的方法，来确定各种吸附剂对各种污染物的吸附能力。本实验主要研究工业发展产生的固体废弃物与废渣作为人工湿地填料对污染物的吸附能力。实验结果表明，空心砖对氨氮的吸附能力强于其他吸附剂，且四种吸附剂的吸附容量随吸附剂量的增加而增大；活性炭对COD的吸附能力强于其他吸附剂，且四种吸附剂对COD的吸附容量存在较大差异。

Pesearch of Adsorption Capacity of Hollow brick for Pollutions in Wastewater

In this paper we mainly study the adsorption capacity of resin,powder of hollow bricks,fly ash,activated carbon,for the pollution factors of ammonia nitrogen,total nitrogen,chemical oxygen demand,total phosphorus in the water.Experiments show that Among four kinds of adsorbent ammonia adsorption capacity of hollow brick is the strongest and its adsorbent series of 1 / n is 0.1475,which is not only an ideal environmentally friendly adsorbent,but also enhances pollutant removal capacity of the ideal filler.The results provide the important theory evidence for study solid wasts and muck to artificial ground.
