23、量充分實驗的基礎上提出的，最終選定了適合貴方實際使用的性能優(yōu)越、穩(wěn)定性好的水處理藥劑配方。水處理配方和技術有很強的針對性，尚需根據(jù)現(xiàn)場實際運行的復雜變化的條件進行合理的調(diào)整。二、循環(huán)水系統(tǒng)工況條件及水質(zhì)條件2.1 循環(huán)水系統(tǒng)工況條件（見表1）表1：循環(huán)水系統(tǒng)工況條件系統(tǒng)名稱冷卻自循環(huán)系統(tǒng)（敞開式）封閉式水循環(huán)系統(tǒng)循環(huán)水量（m3/h）保有水量（m3）補充水量（m3/h）系統(tǒng)材質(zhì)濃縮倍數(shù)循環(huán)水量（m3/h）保有水量（m3）補充水量（m3/h）系統(tǒng)材質(zhì)濃縮倍數(shù)棒材冷卻系統(tǒng)（d區(qū)）390.676.04.0鋼、銅2-2.5倍151.2680.2鋼、銅/擠塑冷卻系統(tǒng)（a區(qū)）194.45.02.0鋼、銅2-

25、統(tǒng)中的重碳酸鹽、cl、so42、ca2+、mg2+濃度均相應增加，假如不采取投加水處理藥劑保護的措施，一方面成垢離子(ca2+、mg2+、hco3-等離子)會在換熱器的傳熱表面形成硬垢，影響換熱效率，甚至堵塞管道，嚴重時導致停車事故的發(fā)生；另一方面水中的腐蝕性離子(cl、so42等)以及溶解氧的存在會造成管道、換熱設備的腐蝕穿孔，影響設備的正常運行，直接縮短設備的使用壽命；另外，由于循環(huán)冷卻水系統(tǒng)的運行條件特別適宜于菌藻粘泥的生長，會對設備及管線產(chǎn)生微生物腐蝕和軟垢，同樣威脅循環(huán)冷卻水系統(tǒng)的安全運行。密閉式循環(huán)冷卻水系統(tǒng)一般在運行過程中水質(zhì)情況變化不大，但由于溶解氧的滲漏和溶入以及成垢離子的存

26、在，水處理應以防腐蝕為主，同時兼顧阻垢。分析貴公司循環(huán)水水系統(tǒng)補充水，從水質(zhì)數(shù)據(jù)及水型判斷結果來看，均為結垢型水質(zhì)。濃縮運行后，隨著濃縮倍率的增加，結垢趨勢加強，濃縮倍數(shù)越高，ph越高，結垢趨勢越強；同時由于水中各種腐蝕性離子隨著濃縮倍率的增加也相應提高，并且水中的溶解氧被飽和，所以水中的腐蝕性不能被忽視。因此，對于該水質(zhì)所選的水處理藥劑配方必須兼顧緩蝕與阻垢兩種特性。同時還應從節(jié)水、節(jié)藥等經(jīng)濟方面加以綜合考慮。敞開式循環(huán)水系統(tǒng)運行條件特別適合于菌藻粘泥的生長，這些微生物的大量滋生，將給系統(tǒng)帶來嚴重危害，一方面這些物質(zhì)沉積在系統(tǒng)換熱設備及管道的表面，影響換熱效率；另一方面也容易發(fā)生微生物腐蝕，

27、被覆蓋的金屬表面為貧氧的陽極區(qū)，周圍金屬表面成為富氧的陰極區(qū)，這種局部氧濃差作用使覆蓋物下形成孔蝕或坑蝕；另外，菌藻粘泥附著于設備表面后影響了緩蝕阻垢劑順利到達設備表面形成保護膜。所以需要為循環(huán)水系統(tǒng)篩選合適的殺菌滅藻劑及粘泥剝離劑以控制系統(tǒng)內(nèi)的菌藻粘泥，同時對形成的粘泥附著物定期剝離，清潔設備表面?？紤]到細菌藻類的抗藥性、粘泥剝離的需要以及特殊處理，本方案建議采用氧化性與非氧化性殺菌滅藻劑配合使用的處理方法，同時根據(jù)系統(tǒng)情況決定是否使用粘泥剝離劑。循環(huán)水系統(tǒng)化學處理方案是依據(jù)貴公司提供的循環(huán)水系統(tǒng)運行工況及水質(zhì)條件提出的，確定的緩蝕阻垢劑配方產(chǎn)品具有以下特點：1）具有優(yōu)良的阻垢性能和緩蝕性能

28、，既對碳酸鈣垢、磷酸鈣垢、硫酸鈣垢、硅垢具有優(yōu)異的阻垢性能；也對氧化鐵、粘泥及水中濁度物質(zhì)具有良好的分散作用；產(chǎn)品容易在金屬表面形成一層薄而致密的防腐膜，從而隔絕循環(huán)水對系統(tǒng)材質(zhì)的腐蝕；2）產(chǎn)品穩(wěn)定性好，耐氯分解能力強，抗污染能力強；3）產(chǎn)品屬于低磷環(huán)保型產(chǎn)品；近年來由于江河污染，海水富營養(yǎng)化，赤潮現(xiàn)象屢見不鮮，世界各地禁磷呼聲越來越高，因此選擇環(huán)保型水處理藥劑是今后冷卻水處理技術的發(fā)展方向。正確應用本處理技術，可取得節(jié)水、節(jié)能和穩(wěn)定生產(chǎn)的良好效益。但應指出，良好水處理效果的取得，既要有先進的處理技術，更需要將此技術加以正確的實施，并在生產(chǎn)應用中進行嚴格的日常管理。為本技術應用獲得成功提供可靠
