style="text-indent:25px">滴定法概述：滴定法*適用于進(jìn)行蒸餾預(yù)處理的水樣。調(diào)節(jié)水樣至pH6.0~7.4范圍，加入氧化鎂使呈微堿性。加熱蒸餾，釋出的氨被吸收入硼酸溶液中，以甲基紅-亞甲藍(lán)為指示劑，用酸標(biāo)準(zhǔn)溶液滴定餾出液中的銨。當(dāng)水樣中含有在此條件下，可被蒸餾出并在滴定時(shí)能與酸反應(yīng)的物質(zhì)，如揮發(fā)性胺類等，則將使測(cè)定結(jié)果偏高。試劑：（1）混合指示液：稱取200mg甲基紅溶于100ml 95%乙醇；另稱取100mg亞甲藍(lán)溶于50ml 95%乙醇。以兩份甲基紅溶液與一份亞甲藍(lán)溶液混合后供用。混合液一個(gè)月配制一次。注：為使滴定終點(diǎn)明顯，必要時(shí)添加少量甲基紅溶液于混合指示液中，以調(diào)節(jié)二者的比例至合適為止。折點(diǎn)氯化法是將氯氣通入廢水中達(dá)到某一點(diǎn)，在該點(diǎn)時(shí)水中游離氯含量較低。</p><div

1、立即停止進(jìn)水進(jìn)行悶爆、內(nèi)外回流連續(xù)開啟。 2、停止壓泥保證污泥濃度。 3、如果有機(jī)物已經(jīng)引起非絲狀菌膨脹可以投加PAC來增加污泥絮性、投加消泡劑來消除沖擊泡沫。氨氮對(duì)水生物起危害作用的主要是游離氨。南昌氨氮去除菌哪個(gè)牌子好</p><p
