ammonia pollution 中文意思是什麼
-
Rainwater is not clean water, because adulterated air pollution content, still have the pollution of the ground and roofing, nitrogen of ion of yin and yang, heavy metal, ammonia often is contained to wait in collection rainwater, a lot of people fear such water passes simple processing, whether humanness is drinkable
雨水並非純凈水，由於摻雜了大氣污染物，還有地面和屋面的污染，收集的雨水中往往含有陰陽離子、重金屬、氨氮等，很多人擔心這樣的水經過簡單的處理，能否為人飲用。 -
Abstract : sewage sludge briquette made of 2 % ( dry basis ) sewage sludge, 0. 3 % white earth, and coal powder was studied under conditions of briquette similar to modeling and gasificaition for briquette on ammonia synthesis. briguette with white earth was taken as a reference. the results showed that rate of gasification of sewage sludge briquette was 50 % higher than that of briquette of white earth at 1100. ash melting point of sewage sludge briquette reached 1440 which satisfied the requirement of gasification of ammonia synthesis. results showed that no pollution took place in these processes, and the gas generated can meet the demand of ammonia synthesis
文摘:以污泥添加量為2 % （干基）白泥添加量為0 . 3 % （干基）所制得的污泥型煤為研究對象，以白泥添加量為5 . 5 %的白泥型煤作為參照，考察了污泥型煤的氣化特性和二次污染.研究結果表明，在1100以上高溫下，污泥型煤的氣化速率比白泥型煤高50 %以上；污泥型煤的灰渣軟化溫度達1440 ，能滿足合成氨氣化要求；污泥型煤無二次污染，其氣化成分符合合成氨原料氣的要求 -
Under the permitted conditions, the all - scale plant was made to pre - ozonation. the results showed : ( l ) the optimal advanced purification drinking water process should be " regular treatment + ozonation + biological activated carbon ". though pre - ozonation had no effects on ammonia nitrogen in the water of micro - pollution water source, instead the turbidity of pre - oxidation finished water was raised, it had effects on killing bacteria and removing algae, and controlling the growth of micro - organism
得出如下結論： （ 1 ）最優化的深度處理飲用水的工藝應該是「常規處理+臭氧化+生物活性炭」 ，如果投加預臭氧，對微污染水源水中的氨氮沒有效果，反而引起預氧化出水的濁度升高，但是對滅菌除藻，控制微生物的生長有一定的作用。 -
Low dissolved oxygen can be harmful to most aquatic life, whereas high 5 - day biochemical oxygen demand and ammonia nitrogen levels indicate the presence of organic pollution and sewage contamination
溶解氧含量過低會危害大部分水生物的生存，而五天生化需氧量和氨氮水平則顯示河溪受有機物和生活污水污染。 -
Based on the study of application of chloramines disinfection at home and abroad, local water quality and practices, this paper makes some implications on the relationships between chloramines disinfection and water quality as followed. 1. it is more effective to disinfect water by means of " first chloramines, then ammonia " in lowering pollution
其主要研究工作和結論如下： 1 、相對于先氯后氨和同時氯氨的消毒劑投加方式，先氨后氯的投加方式在降低原水酚污染影響的作用更為有效。
