style="text-indent:25px">水處理目的是提高水質(zhì)，使之達(dá)到某種水質(zhì)標(biāo)準(zhǔn)。按處理方法的不同，有物理水處理、化學(xué)水處理、生物水處理等多種。按處理對象或目的的不同，有給水處理和廢水處理兩大類。給水處理包括生活飲用水處理和工業(yè)用水處理兩類; 廢水處理又有生活污水處理和工業(yè)廢水處理之分。其中，與熱工技術(shù)關(guān)系特別密切的有從屬于工業(yè)用水處理范疇的鍋爐給水處理、補給水處理、汽輪機主凝結(jié)水處理以及循環(huán)水處理等。水處理對發(fā)展工業(yè)生產(chǎn)、提高產(chǎn)品質(zhì)量，保護(hù)人類環(huán)境、維護(hù)生態(tài)平衡具有重要的意義。</p><p> 微生物較適宜在什么溫度范圍內(nèi)生長繁殖？在廢水生物處理中，微生物較適宜的溫度范圍一般為16-30℃，較高溫度在37-43℃，當(dāng)溫度低于10℃時，微生物將不再生長。在適宜的溫度范圍內(nèi)，溫度每提高10℃，微生物的代謝速率會相應(yīng)提高，COD的去除率也會提高10%左右；相反，溫度每降低10℃，COD的去除率會降低10%，因此在冬季時，COD的生化去除率會明顯低于其它季節(jié)。 </p> <p> 微生物較適宜的pH條件應(yīng)在什么范圍？微生物的生命活動、物質(zhì)代謝與pH值有密切關(guān)系。大多數(shù)微生物對pH的適應(yīng)范圍在4.5-9，而較適宜的pH值的范圍在6.5-7.5。當(dāng)pH低于6.5時，細(xì)菌開始與細(xì)菌競爭，pH到4.5時，細(xì)菌在生化池內(nèi)將占完全的優(yōu)勢，其結(jié)果是嚴(yán)重影響污泥的沉降結(jié)果；當(dāng)pH超過9時，微生物的代謝速度將受到阻礙。不同的微生物對pH值的適應(yīng)范圍要求是不一樣的。在好氧生物處理中，pH可在6.5-8.5之間變化；厭氧生物處理中，微生物以pH的要求比較嚴(yán)格，pH應(yīng)在6.7-7.4之間。
