苯胺對氨氮硝化反應(yīng)抑制作用的實證研究
發(fā)布時間:2018-11-25 09:13
【摘要】:某污水處理廠出水氨氮不達標(biāo),經(jīng)調(diào)查發(fā)現(xiàn)該廠進水中含有苯胺。圍繞苯胺對活性污泥硝化作用的影響,開展了相關(guān)研究。結(jié)果表明,苯胺可抑制活性污泥的硝化作用,且其濃度越高抑制作用越強;當(dāng)系統(tǒng)中苯胺濃度超過3 mg/L時,可使污泥喪失硝化能力;適當(dāng)提高活性污泥濃度可使抑制作用減弱;對于短時間受抑制的活性污泥,若苯胺不再進入,其硝化能力將逐漸恢復(fù)。
[Abstract]:Ammonia nitrogen in effluent of a sewage treatment plant is not up to standard, and aniline is found in the influent of the plant. The effect of aniline on nitrification of activated sludge was studied. The results showed that aniline could inhibit the nitrification of activated sludge, and the higher the concentration of aniline was, the stronger the inhibition was, and when the concentration of aniline in the system was more than 3 mg/L, the nitrification ability of activated sludge could be lost. Increasing the concentration of activated sludge could weaken the inhibition effect, and if aniline no longer entered, the nitrification ability of activated sludge would gradually recover.
