蜂窝煤渣对氨氮吸附特性探讨

Research of briquettes residue on the characteristics of ammonia adsorption

通过对蜂窝煤渣用量、pH值、吸附时间、氨氮浓度、离心时间对氨氮吸附特性的影响试验,探讨了利用蜂窝煤渣吸附法去除废水中氨态氮的可行性。结果表明:蜂窝煤渣用量2.00 g,pH值4～6,吸附时间90 min,氨氮的初始浓度5.0 mg/L,离心时间10 min条件下,对氨氮的去除率比较高。将燃烧后废弃物作为吸附材料,可以减少环境污染,在一定程度上达到了去除氨氮的效果,具有良好的发展前景。

Following the 80 heads of the briquettes contain residue on the absorption of ammonia solution, inspected the briquettes amount of slag, pH, adsorption time, the ammonia concentration on the impact of ammo-nia adsorption. The results showed that： the amount reached 2.00 g, pH value in the 4-6, adsorption time 90 min, briquettes residue on 5.0 mg/L concentration of ammonia solution, centrifuge time was right about 10 min, bri-quettes residue on the ammonia nitrogen removal rate was higher. It is a residue after burning the waste, as a absorption material, it can not only reduce environmental pollution but also remove ammonia in a certain extent,, with good prospects for development.
