在化工企業(yè)中，有許多廢水是含較高濃度的***鈉廢水，因含鹽量較高無法直接進(jìn)行生化處理，因此一般采用多效蒸發(fā)結(jié)晶技術(shù)，得到無水***鈉固廢，冷凝水回用或進(jìn)一步處理；近些年隨著MVR熱泵蒸發(fā)器的興起，因其較低的處理能耗得到較多推崇，但是由于壓縮風(fēng)機(jī)均為進(jìn)口設(shè)備，投資較高。那么，究竟有沒有一個(gè)投資相對(duì)更小、處理能耗更低的工藝路線呢。針對(duì)***鈉的物料特性，其既可以通過蒸發(fā)得到無水***鈉結(jié)晶，又可以通過冷凍得到含十個(gè)結(jié)晶水的芒硝（即十水***鈉）；同時(shí)，隨著膜濃縮技術(shù)的進(jìn)步，通過膜濃縮可以將原料液及結(jié)晶母液濃度提升至15%左右，因此我們獨(dú)辟蹊徑，采用膜濃縮及冷凍結(jié)晶脫硝組合工藝，得到芒硝晶體及膜過濾得到的潔凈水。那么，這種組合結(jié)晶的工藝和多效蒸發(fā)結(jié)晶技術(shù)、MVR蒸發(fā)結(jié)晶技術(shù)相比，在投資及能耗上究竟有多大優(yōu)勢(shì)及合理性呢，就此，我們以日處理200噸含量為18%的***鈉廢水為例，進(jìn)行具體比較。一、設(shè)計(jì)條件：每天處理200m3其中含***鈉18%，比重為1131kg/m3,按每天運(yùn)行20小時(shí)計(jì)。來料溫度200C二、設(shè)備選型根據(jù)***鈉的特性及本系統(tǒng)廢水中***鈉的含量，可選用下列幾種處理方式1）通過冷凍結(jié)晶+膜濃縮組合處理工藝得到十水***鈉與純水。</p><p style="text-indent:25px">在工業(yè)清洗劑應(yīng)用中，分成兩種清洗劑，即溶劑型清洗劑和水基型清洗劑。顧名思義，溶劑型清洗劑，就是選用合適的有機(jī)溶劑有效溶解目標(biāo)油污，然后通過高壓蒸餾的方法提純有機(jī)溶劑，實(shí)現(xiàn)溶劑型清洗劑的循環(huán)使用。使用溶劑型清洗劑，對(duì)清洗設(shè)備的要求較高，設(shè)計(jì)復(fù)雜，造價(jià)不菲且使用安全性的余量較大，成本較高。水基型清洗劑，因其使用可以用水稀釋，水作為大量的主要廉價(jià)溶劑，得到***的工業(yè)應(yīng)用。再用因安全性，以及對(duì)設(shè)備的要求低，操作簡(jiǎn)單，適合大量生產(chǎn)，因此應(yīng)用***。水基型清洗劑是綜合了乳化法與皂化法的優(yōu)點(diǎn)，進(jìn)行清洗劑配方的優(yōu)先復(fù)配，實(shí)現(xiàn)穩(wěn)定的體系結(jié)構(gòu)與實(shí)現(xiàn)分工協(xié)作和互補(bǔ)。以得到較高的清洗效率，較徹底的油污剝離能力為優(yōu)先，進(jìn)行配方的設(shè)計(jì)。過鹽通常以銨鹽、鉀鹽和鈉鹽的形式存在，原位化學(xué)氧化技術(shù)中一般采用過鈉。</p><div

酒精存在于所有酒精類飲料、部分醫(yī)藥化工產(chǎn)品里，以及部分醫(yī)療和工業(yè)用途。正因?yàn)槭秤镁凭谌藗兊纳钪杏猛?*廣，成分很復(fù)雜，所以國(guó) 家管理嚴(yán)格、規(guī)范。可以說，食用酒精本身沒安全問題。<br/> ——酒精的區(qū)別在于用途。<br/> 理論上，酒精本身并沒有區(qū)別，都是乙醇，區(qū)別在于酒精里其他物質(zhì)和含量，同時(shí)根據(jù)酒精的用途，決定要不要排除所含的其他物質(zhì)。譬如工業(yè)酒精，不是用于吃喝，就不用考慮食品安全，只要保證足夠的酒精濃度就行。所以，害人的甲醇，就沒必要提取出來。但是食用酒精就要盡量剔除甲醇，把含量壓低到標(biāo)準(zhǔn)范圍以內(nèi)。<br/> ——酒精的價(jià)格差別很大。<br/> 工業(yè)酒精制備成本很低，價(jià)格也便宜，于食用級(jí)差著幾倍。***的價(jià)格，工業(yè)酒精1600元/噸，食用酒精8500元/噸。這個(gè)差價(jià)，就是酒精酒初期屢屢違法案發(fā)的動(dòng)力源頭。一斤酒的材料成本還不到一塊錢，而且還是現(xiàn)在的價(jià)格，上世紀(jì)八、九十年代會(huì)更便宜。所以違法分子敢鋌而走險(xiǎn)。<br/>
