Two methods were used to provide water quality ratings in bio - assessment using biotic index ( bi ), ( 1 ) using the sampled sites meet the criteria for undisturbed and minimally impaired conditions, the confidence in the distribution of bi value for the 75th percentile to be used as the criterion dividing " unimpaired " form " impaired ". any values below the 75th percentile were considered as " excellent ", and values above the 75th percentile, was quadrisected for different water quality ratings
採用兩種方法研究m指數劃分水質級別的標準： （ 1 ）無污染樣點的m指數值法，以75分位數值作為最清潔水質標準，將高於此值的可能分佈范圍一等分，分別代表不同的水質級別zk ）所有樣點（污染與無污染樣點）的bi指數值法，以5分位數值作為最清潔水質的標準，將高於此值的可能分佈范圍4等分，分別代表不同的水質級別。Although disquieting and of course unacceptable that a non - food grade additive was found in some foods, it is also reassuring to know that legal mechanisms are in place to protect consumers ; the technology exists and is increasingly being employed to analyse foodstuffs for even minute quantities of contaminants, and of course that trace back systems are in place to exactly identify and remove sub - standard products
盡管非食用級的添加劑出現在食品中確實令人不安也無法接受，但令人安慰的是，還有立法機制在保護消費者現有技術日益被應用於分析食品中的微量污染物，同時食品追蹤系統也可用來確認並清除不符合標準的產品。This paper summarizes the pollutants in raw water and their removal techniques, the water treatment process puts emphases on full - process and multi - layer safety barrier techniques, including water resource protection and water body restoration, raw water sale transport, safe purification in waterworks, safe distribution in pipe etc drinking water safety can he ensured by adopting multi - layer safety barrier technique to meet stricter drinking water quality standards
摘要分析源水中污染物質及其去除技術，國內外飲用水處理工藝採用全流程、多級安全保障技術，包括水源保護與水體修復，原水安全輸送，水廠內安全凈化，管網水安全輸配等，以期將污染物質降至水質標準以下，確保飲用水安全。The characteristics of single factor water quality identification index are : firstly, it can completely identify the important information including water quality classification of assessed factors, water quality monitoring data, planned water quality classification of water environment function area ; secondly, it can evaluate the selected factors qualitatively by national water quality standards, and water quality monitoring data ; thirdly, it can be used to compare water quality of the same assessed factors in the same classification and water quality of different assessed factors
單因子水質標識指數可以完整標識水質評價指標的類別、水質數據、功能區目標值等重要信息，既能按國家標準類別定性評價，又能根據標識指數進行水質數據的分析；既可以比較分析同一類水質指標在同一級別中的差異，也可以在不同類別水質指標中比較分析水質的污染程度。It has been shown that this updated sampling and measurement method, which can measure the content of tar and dust individually, appears much more precise and credible, particularly aiming at the characteristic of heavy tar and dust content in biomass gas. this clarification system that adopts two - level shell and tube condensers and one tar removal filter, has the advantages of high removal efficiency ( 97 % ~ 98 % ) and low operating cost. besides, it has been made more environmentally friendly considering that wastewater from condensers has measured up to related effluent state standards after being disposed in tar clarifier - tank
多次試驗表明：針對生物質氣浙江大學碩士學位論文含焦油灰塵量大的特點，改進的生物質焦油取樣測量法可實現焦油和灰塵的分離，有較高準確性和可靠性；採用二級管殼式冷凝器與一級乾式過濾器結合的燃氣冷凝凈化系統不但凈化效率高（ 97 98 ） 、運行費用低，而且含焦油廢水二經過澄清池澄清處理后可達到國家相關污水排放標準，避兔了濕式凈化系統的水污染；兼顧凈化效果、經濟性和減少污染考慮，採用以半焦為吸附材料的于式凈化系統可以達到炊用燃氣對焦油含量的要求。分享友人
