空心砖对废水中污染物吸附能力的研究

Pesearch of Adsorption Capacity of Hollow brick for Pollutions in Wastewater

研究了树脂、空心砖粉、粉煤灰、活性炭4种吸附剂对水体中氨氮、总氮、化学需氧量、总磷等污染因子的吸附能力。实验表明,4种吸附剂中空心砖对氨氮的吸附能力最强,其吸附剂能级数(1/n)为0.1475,因此,是一种增强系统对污染物去除能力的理想填料。为研究工业固体废弃物与废渣作为人工湿地填料提供理论依据。

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.
