style="text-indent:25px">工作原理編輯污水處理廠使用的分析儀有兩種：pH計(jì)和溶氧分析儀。pH計(jì)水的pH值隨著所溶解的物質(zhì)的多少而定，因此pH值能靈敏地指示出水質(zhì)的變化情況。pH值的變化對(duì)生物的繁殖和生存有很大影響，同時(shí)還嚴(yán)重影響活性污泥生化作用，即影響處理效果，污水的pH值一般控制在6.5～7之間。水在化學(xué)上是中性的，某些水分子自發(fā)地按照下式分解：H2O=H++OH-，即分解成氫離子和氫氧根離子。在中性溶液中，氫離子H+和氫氧根離子OH-的濃度都是10-7mol/l，pH值是氫離子濃度以10為底的對(duì)數(shù)的負(fù)數(shù)：pH=-log，因此中性溶液的pH值等于7。如果有過量的氫離子，則pH值小于7，溶液呈酸性；反之，氫氧根離子過量，則溶液呈堿性。 pH值通常用電位法測(cè)量，通常用一個(gè)恒定電位的參比電極和測(cè)量電極組成一個(gè)原電池，原電池電動(dòng)勢(shì)的大小取決于氫離子的濃度，也取決于溶液的酸堿度。該廠采用了CPS11型pH傳感器和CPM151型pH變送器。具體結(jié)構(gòu)如圖1所示，測(cè)量電極上有特殊的對(duì)pH反應(yīng)靈敏的玻璃探頭，它是由能導(dǎo)電、能滲透氫離子的特殊玻璃制成，具有測(cè)量精度高、抗干擾性好等特點(diǎn)。當(dāng)玻璃探頭和氫離子接觸時(shí)，就產(chǎn)生電位浙江口碑好水質(zhì)分析儀報(bào)價(jià)多參數(shù)同時(shí)進(jìn)行分析，同時(shí)出結(jié)果并打印報(bào)告單。</p><div
