吸氨沸石如何使用？

每畝每米水深使用沸石粉25-50公斤，可起到除去水中95%氨氮，凈化水質(zhì)增加溶氧的作用，同時提高水體總堿度，穩(wěn)定水質(zhì)。

沸石的作用是防止暴沸（生成的蒸氣太大，使液體劇烈翻滾，不安全）冷卻的液體（內(nèi)含沸石）應(yīng)該可以繼續(xù)直接加熱，至少與沸石無關(guān)，只要冷液體允許就行。沸石是火山熔巖形成的一種架狀結(jié)構(gòu)的鋁硅酸鹽礦物。目前已知的沸石有五十多種，應(yīng)用于養(yǎng)殖業(yè)的天然沸石主要的是斜發(fā)沸石和絲光沸石。

吸氨沸石如何使用？

我覺得直接放魚缸就行吧這是沸石的介紹：

沸石（Zeolite）火山熔巖形成的一種架狀結(jié)構(gòu)的鋁硅酸鹽礦物。沸石有獨(dú)特的礦物結(jié)構(gòu)，其結(jié)構(gòu)為三維硅氧四面體和三維鋁氧四面體，這些四面體按一定的規(guī)律排列成具有一定形狀的晶體骨架。沸石的礦物骨架是一開放性的，具有很多的大小均一的通道和空腔（3~11）。在這些孔穴和通道中吸附著金屬陽離子和水分子，這些陽離子和水分子與陰離子骨架間的結(jié)合力較弱。沸石的這種特殊結(jié)構(gòu)決定了它所特有的性能 ,屬弱酸性陽離子交換劑。沸石晶體內(nèi)部的孔穴和通道的體積約占晶體總體積的一半以上，在孔穴和通道中存在許多沸石水，經(jīng)加熱水分可以逸失。失水后的沸石，形成了表面積很大的孔穴，一克沸石孔穴和通道的內(nèi)表面積可達(dá)500~1000平方米。這種多孔結(jié)構(gòu)決定它具有很強(qiáng)的吸附性。可吸附大量的有極性的分子，而且對水中有害的重金屬及有機(jī)物,具有吸附交換作用，也有利于去除水中各種微污染物且水浸出液不含有毒，有害人體物質(zhì)，去除水中鐵、氟、氨效果更為顯著。沸石粉不僅具有特定的結(jié)構(gòu)，還含有豐富的礦物元素，沸石作為一種含堿金屬、堿土金屬和稀土金屬的鋁硅酸鹽礦物，含有K、Ca、Mg、Al、Fe、Cu、Zn、Mn、B等多種大量和中微量元素，在水產(chǎn)養(yǎng)殖中，不僅是優(yōu)質(zhì)的水質(zhì)改良劑，還是很好的飼料添加劑。將沸石粉直接撒入水中，可調(diào)節(jié)PH值，吸附水中的有害氣體、有害物質(zhì)和藥物。增加含氧量，提高魚類成活率。在飼料中加入3—6%的沸石粉，可使魚明顯增重，特別是在消化道內(nèi)能起到氨容器作用，對提高機(jī)體內(nèi)酶的活性、促進(jìn)新陳代謝和增強(qiáng)機(jī)體抗病能力效果顯著，同時還可減少腸道疾病的發(fā)生， 更可有效地抑制飼養(yǎng)環(huán)境的臭味。

再生處理

目前，在水族市場出售的沸石，大多數(shù)呈粒狀或粉末狀。但由于沸石的價格比較便宜，許多水族愛好者在使用沸石失去功效以后就會丟掉，再重新購買使用。其實(shí)，在沸石使用的過程中，只把沸石放入過濾器，而不加以處理的話，是不能保持水質(zhì)干凈的。只有通過定時清理、定期“再生”，才能夠繼續(xù)保持沸石的水質(zhì)過濾功效。沸石的吸附能力有限，所以逐日累積在沸石孔隙中的污垢是必須要即時清除的。這段定時清除的時間，在水質(zhì)一般正常的情況下，夏季一個月清除“再生”一次，而冬季則可延長至三個月清除“再生”一次，或根據(jù)實(shí)際水質(zhì)處理情況，自行控制延長或縮短清除“再生”的時間。所謂“再生”，就是再活性而恢復(fù)原有過濾功效的意思。而沸石的“再生”處理其實(shí)很簡單，只要將過濾器中使用沸石稍加清洗，去除表面較大的污垢等累積雜質(zhì)以后，放入飽和狀態(tài)的食鹽水中浸泡（因食鹽中的離子能夠吸除沸石多孔隙中累積的不能清洗處理的細(xì)微雜質(zhì)，沸石因此就能回復(fù)新的狀態(tài)。而食鹽與沸石的再生處理的比例一般控制在1：3），這樣浸泡一整天以后再在太陽光下晾曬半天，就能使沸石的過濾效果完全恢復(fù)。
