style="text-indent:25px">1980年氣水反沖技術(shù)也在很大程度上得到了普遍應(yīng)用；有些技術(shù)先進(jìn)的水廠已經(jīng)開始使用臭氧化工藝。在這一階段，水質(zhì)濁度的測定也又有了較大地改進(jìn)，先由原有的比色管比濁改進(jìn)成了黑利格型目視比濁儀，直至后來出現(xiàn)的光電濁度儀。1980年~1990年，在這些年里，是我國水質(zhì)研究發(fā)展相當(dāng)重要的一段時期，國內(nèi)在水質(zhì)研究問題上首先采用了遺傳毒理學(xué)的研究方法，在水處理工藝方面采用臭氧與氯的聯(lián)用試驗。試驗表明水中有機(jī)物的不完全氧化過程，會導(dǎo)致突變率增高，從而改善了單純地使用臭氧進(jìn)行消毒導(dǎo)致的突變率下降的現(xiàn)象，臭氧與氯聯(lián)用還能有助于提高出廠水中重金屬含量的合格率，其中包括鐵、錳、銫等；</p><p style="text-indent:25px">水質(zhì)常規(guī)五參數(shù)有水溫、PH、溶解氧、電導(dǎo)率和濁度。這些項目可通過探頭直接給出各參數(shù)值，不需要復(fù)雜的操作過程，可以實時地顯示（《水和廢水監(jiān)測分析方法（第四版）》第三篇綜合指標(biāo)和無機(jī)污染物第五章水質(zhì)自動監(jiān)測系統(tǒng) ）。為什么要對水溫、PH、溶解氧、電導(dǎo)率和濁度常規(guī)指標(biāo)進(jìn)行監(jiān)測呢？首先，水溫，如果地表水溫變化太大會影響魚蝦貝類的進(jìn)食速度，進(jìn)而還會對他們的繁殖時間和效率造成影響，不僅如此，水溫變化還會影響水生植物、微生物的正常生長；其次，PH，PH值是水質(zhì)的重要指標(biāo)，不僅直接影響魚蝦殼類水生物的生理活動，而且還通過改變水體環(huán)境中的其他理化及生物因子間接作用于魚蝦殼類，在水體中PH值可以十分直觀的反映著水質(zhì)的變化，比如藻類的活力、二氧化碳的存在狀態(tài)等；有毒性的水質(zhì)檢測儀試劑,不管濃度大小,必須使用多少配制多少。</p><div
