src="/plus/count.php?view=yes&aid=1651&mid=1"type='text/javascript' language="javascript"></script></h6> </div> </div> <div class="nr_text"> <div> <span style="font-family:宋體;"><span style="font-size:16px;">1、將SDI測試儀安裝在純化水設備RO系統的測試位置上。如果測試點在預處理系統后，那么當測試SDI值時，RO系統應該正常運行，否則最后的測試結果就會無效。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">2、開始時，SDI測試儀內不能放0.45μ微孔過濾膜。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">3、測試儀連接完成后，打開測試儀上的閥門，讓被測水直接流過測試儀幾分鐘。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">4、關上閥門，用專用鑷子放一張0.45μ白色微孔過濾膜（亮的一邊朝上）在測試儀的膜盒支撐板上并輕輕地壓緊“0”型圈及膜盒上蓋，擰上塑料螺絲，但不要太緊。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">5、將閥門打開一部分，當水流過測試儀時，慢慢旋松一個或兩個塑料螺絲，讓水漫出測試儀，以逐出測試儀內的空氣。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">6、確定測試儀內已經沒有空氣了，輕輕旋緊塑料螺絲。完全打開閥門，將減壓閥壓力調節到0.2MPa(207KPa)，保持住該壓力，關上閥門。整個測試期間，壓力必須保持不變。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">7、用合適的容器收集水樣本。只要保證每次用同樣的容量測試，容量的大小并不重要。容量可在100到500毫升之間。不同的容器都可用：例如量筒、大口杯、咖啡杯、可口可樂瓶等。一般考慮收集500毫升水樣。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">8、完全打開閥門，用秒表測量收集500毫升水樣所需要的時間，并記錄為T（1）=__秒。收集完后，仍繼續保持閥門打開，讓水繼續流出。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">9、過5分鐘后再用秒表測量收集另一個500毫升水樣所需要的時間并記錄為T（5）=__秒，過10及15分鐘后各做一遍同樣的測試并分別記錄為T（10）和T（15）。檢測結束后，SDI值就能被計算出來。有些水樣數據采樣可能要求延續到T（20），T（30）甚至T（60），當然這種水樣是極少數的。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">10、測定水溫。在整個測試期間，水溫必須保持一致。</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">11、SDI值由下列公式計算得出：</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">SDI=100P30/ Tt =100（1-T1/ T2）/ Tt</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">P30 -----在207kpa進水壓力下的堵塞指數；</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">Tt總的測試時間（分）通常為T15，此時P30＜75%，不然測試T10或T5，使此時的P30＜75%</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">T1　-----初始時收集500ml水樣所需的時間（秒）；</span></span></div> <div> <span style="font-family:宋體;"><span style="font-size:16px;">T2　-----經T1（通常為T15，即15分鐘）后收集500ml 水樣所需的時間（秒）。</span></span></div> <br /> <hr /> <p> 上一篇：<a href='/technical/1650.html'>為什么水處理設備在冬天產水量會下降</a> </p> <p> 下一篇：<a href='/technical/1652.html'>過濾增壓兩不誤，農村用水新玩法</a> </p> </div> <div
