【摘要】：為保證出水水質(zhì)穩(wěn)定并提高氨氮去除率,實(shí)現(xiàn)CANON工藝的優(yōu)化,利用SBR反應(yīng)器進(jìn)行了基于實(shí)時(shí)控制技術(shù)的CANON工藝穩(wěn)定性研究.試驗(yàn)過(guò)程中,溫度控制在30℃±1℃,pH 7~8,通過(guò)反應(yīng)過(guò)程中氨氮、硝態(tài)氮、亞硝態(tài)氮和pH、DO、ORP的變化規(guī)律,制定了可行的實(shí)時(shí)控制策略.結(jié)果表明,進(jìn)水氨氮濃度為917~1 540 mg·L~(-1)時(shí),以6 mg·L~(-1)的剩余氨氮濃度作為控制參數(shù)可以滿足工藝穩(wěn)定性的要求,但氨氮傳感器存在費(fèi)用昂貴和誤差較大等問(wèn)題.采用pH、DO和ORP曲線的平臺(tái)和特征點(diǎn)作為自控參數(shù),可以維持CANON工藝的長(zhǎng)期穩(wěn)定運(yùn)行,保證氨氮去除率平均維持在99%以上且出水水質(zhì)穩(wěn)定.
[Abstract]:In order to ensure the stability of effluent quality and improve the removal rate of ammonia nitrogen and realize the optimization of CANON process, the stability of CANON process based on real-time control technology was studied by using SBR reactor. During the experiment, the temperature was controlled at 30 鈩，
