中文拼音 [yùjiā]
預加氯
英文
prechlorination-
The transferabilities of disinfectant outgrowths. the transformations admixed with chloroamine disinfectant water and chlorizating disinfectant water in conveying tubes have been particular analyzed. mostly work and conclusions as follows : ( 一 ) using simulative test and crosswise test, changing some parameters such as the sequence and proportion of chloroamine affiliated
C ）採用氯胺消毒方式時，預加氯成為總三鹵甲烷、鹵乙酸生成量的決定因素，取消預加氯將大幅度減少氯消毒副產物的生成，而對于濾后水消毒劑量（主要為一氯胺）的控制影響不大。Based on the residue monitoring results in the previous year, especially on the feedback information of the positive ( non - compliance ) results, and taking account of world - wide alert notifications, samples of some items to be taken will be duly increased year by year ; based on the reasonable suggestions in fvo inspection report and the problems of chloramphenicol and nitrofuran which had been notified by eu in recent years, the monitoring items are being added in order to meet the residue requirement of importing countries and regions such as the eu, japan, korea, switzerland and hk
國家質檢總局根據上一年度殘留監控結果反饋情況，特別是陽性結果的檢出情況，結合各國預警通報的情況，每年適當增加對應監控的檢測項目的取樣數量；尤其是針對歐盟每次考察報告中對我殘留監控計劃提出的合理化建議和近年來歐盟通報的氯黴素和硝基呋喃問題，增加了滿足歐盟、日本、韓國、瑞士、香港等國家和地區殘留監控要求的項目。The enzyme - linked immunosorbent assay ( elisa ) and high performance liquid chro - matography ( hplc ) analysis for detection of mc were optimized. the removal rates of mc by conventional water treatment processes were investigated through the laboratory study and the detection of mc in every process in meiyuan drinking water treatment plant. results showed that the prechlorination of eutrophic water led to the release of intracellular toxins to water phase
本文完善了mc的elisa和hplc分析方法，通過模擬試驗及水廠實測調查了富營養化太湖水中mc在常規凈水工藝中的去除特性，結果表明預氯化使藻細胞內的mc釋放出來，混凝沉澱對細胞外mc無去除作用，砂濾可去除17 . 2 40 . 4的細胞外mc和19 . 0 36 . 6的總mc ，加氯消毒對細胞外mc和總mc的去除率分別為30 45 . 3和30 51 . 7 。In light of various pollution situations and various water treatment processes of two water factories, better solved the problems about throwing doses, throwing localities, throwing forms of composite potassium permanganate and powder activated carbon, as well as compared the enhanced coagulation efficacy of combined process of composite potassium permanganate and powder activated carbon, composite potassium permanganate pre - oxidation and pre - chlorination
針對兩水廠不同的源水污染狀況和現有的水處理工藝，通過室內和生產性試驗，很好地解決了高錳酸鉀復合藥劑、粉末活性炭最佳投加點、投加量和投加方式的確定問題，並對兩者聯用的強化混凝效果與預氯化、單獨高錳酸鉀復合藥劑預氧化進行了對比。6. the durability of concrete structures resisting chloride diffusion in different water cement ratio and different contents of fly ash and silica was analyzed and durable life was predicted based on the results of the test, which will be helpful to preparation of high performance concrete ( hpc ) as well as durability design and assessment of concrete structures
系統地研究了低水膠比及摻加粉煤灰、硅灰的高性能混凝土的電滲透性和氯離子擴散系數，分析了水膠比以及粉煤灰和硅灰等活性集料對混凝土結構抵抗氯離子侵蝕的耐久性能的影響，並對高性能混凝土結構抗氯離子侵蝕的耐久壽命進行了預測，為氯鹽污染環境下高性能混凝土的配製以及混凝土結構耐久性評估與設計提供參考。分享友人
