    摘要:

    為實現(xiàn)高氨氮豬場養(yǎng)殖廢水高效脫氮處理,，針對豬場廢水中尿素（主要源于豬尿液）水解過程伴隨著污水pH值的變化現(xiàn)象，采用序列間歇式活性污泥法（SBR）處理某豬場養(yǎng)殖廢水，在常溫（20℃）,、非限制溶解氧的條件下,，考察了pH值,、曝氣時間等因素對氨氮去除效果和短程硝化特性的影響,。實驗結(jié)果表明,，pH值在7.0~9.5范圍內(nèi)亞硝酸鹽積累率在75%~80%之間；長時間曝氣并未對短程硝化造成影響,；高質(zhì)量濃度氨氮廢水生物處理過程中，亞硝酸鹽積累與進水pH值,、游離氨（FA）及游離亞硝酸（FNA）有關(guān),。

    Abstract:

    In order to achieve high efficient nitrogen removal from high ammoniumnitrogen swine wastewater, sequencing batch reactor activated sludge process (SBR) was used to treat swine wastewater to the phenomenon which the urea (mainly from pig urine) hydrolysis of swine wastewater was accompanied by changes of pH value. Under conditions of normal temperature (20℃) and non-restricted dissolved oxygen, effects of pH value and aeration time on ammonium removal, characteristics of shortcut nitrification were studied. The results showed that nitrite accumulation rate was 75%～80% when pH value was 7.0～9.5. Shortcut nitrification would not affected by long-term aeration. In the biological treatment process of high ammonium-nitrogen wastewater concentration, the nitrite accumulation was related to levels of pH value, free ammonia (FA) and free nitrite (FNA) in influent.
