在室内模拟条件下,研究了淮北临涣煤矿塌陷水域底泥对氨氮的吸附释放特征,结果表明:临涣塌陷水域底泥对于氨氮的吸附能力很强,一经接触便被吸附,吸附量接近1000mg/kg ;而底泥对氨氮的释放是一个复杂动态过程,各采样点各深度处土样的氮释放量相对于吸附量来说都较小,上层底泥氨氮达到释放最大值所需的时间要少于下层底泥。
在室內模擬條件下,研究瞭淮北臨渙煤礦塌陷水域底泥對氨氮的吸附釋放特徵,結果錶明:臨渙塌陷水域底泥對于氨氮的吸附能力很彊,一經接觸便被吸附,吸附量接近1000mg/kg ;而底泥對氨氮的釋放是一箇複雜動態過程,各採樣點各深度處土樣的氮釋放量相對于吸附量來說都較小,上層底泥氨氮達到釋放最大值所需的時間要少于下層底泥。

Under the indoor simulated conditions ,this article studies the ammonium adsorption characteristics onto the sediment deposition from Linghuan coal mining subsided water area in Huaibei ,northern city of Anhui Province .The results show that the sediment in Linhuan collapse waters have a strong adsorption capacity onto ammonium ,and it will be adsorbed as soon as contacting with the sediment which adsorption capacity is near 1000mg/kg .However , releasing ammonia from sediment is a complex dynamic process .The capacity of release is smaller than the capacity of adsorption and the time for ammonia reaching the release maximum of the upper sediment is shorter than that of the low er sediment .
