1. ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study. little difference in total counts of bacteria, actinomycetes and fungi was observed between the contaminated and the non - contaminated soil. compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil
一、甲基對硫磷長期污染對土壤微生物的生態學效應研究了有機磷農藥甲基對硫磷長期污染對土壤微生物的影響,實驗表明:土壤細菌、放線菌、真菌總的數量影響不大;自生固氮菌和反硝化細菌數量減少;氨化細菌、亞硝化細菌、硝化細菌的數量在污染土壤中卻有所增加;與對照土壤相比,污染土壤呼吸作用下降了29 . 93 ;氨化作用和硝化作用強度得到增強。The annual productive capacity of the major products are : 13. 8 thousand tons of melamine, 400 thousand tons of urea, 100 thousand tons of calcium carbide, 4000 tons of dicyanamide, 11 thousand tons of white carbon black, 10 thousand tons of edible liquid co2, 20 thousand tons of calcium cyanamide, 30 thousand tons of methanol, 10 thousand tons of formaldehyde, 50 thousand tons of n. p. k. compound fertilizer, 200 tons of guanidine nitrate and 500 tons dissolved acetylene. the calcium carbide is the fine quality product awarded by the state

摘要通過對箬跳、青山2個深水網箱養殖區的水質狀況的調查數據分析發現,養殖海區的無機氮和氨氮含量明顯升高,但是深水網箱養殖海區的總體污染狀況要比海區小。In this study the main form of the nitrogen that diffused from sediment into overly water was ammonia, and the submerged plant decreased the diffusion fluxes of ammonia and nitrate at water - sediment interface
總之,水沉積物界面氨氮是沉積物向上覆水擴散的主要氮組分,沉水植物降低了氨氮和硝態氮的擴散通量。This course demonstrate the important sorts of wastewater analysis, it includes chemical oxygen demand ( cod ), biochemical oxygen demand ( bod ), suspended solids ( ss ), volatile suspended solids ( vss ), ammonia nitrogen, organic nitrogen, nitrite nitrogen, nitrate nitrogen, orthophosphate, total phosphate, sulfate, and sulfide
本課程包含污水分析重要項目的原理解說及實驗分析,分析項目包括:化學需氧量、生化需氧量、懸浮固體物、揮發性懸浮固體物、氨氮、有機氮、亞硝酸鹽氮、硝酸鹽氮、正磷酸鹽、總磷、硫酸鹽及硫化物。The potential for river eutrophication was originally measured by seven nutrient parameters : ammonia - nitrogen, nitrite - nitrogen, nitrate - nitrogen, total kjeldahl nitrogen, ortho - phosphate, total phosphorus, and silica. more recently, in 2001, two further parameters relating to eutrophication were added. these are the plant pigment parameters of chlorophyll - a and pheo - pigment
多年來我們根據七項營養參數水平來評估河水富營養化的可能性:氨氮亞硝酸鹽氮硝酸鹽氮總凱氏氮正磷酸鹽總磷量及硅,於2001年我們增加了兩項關于富營養化的植物色素新參數:葉綠素- a及葉綠素分子色素。Photography - processing waste - determination of total amino nitrogen microdiffusion kjeldahl method
攝影.沖洗廢液.氨態氮總含量的測定The results indicated that on average the rank order of the concentrations of different nitrogen species in overlying water and porewater was organic nitrogen > ammonia > nitrate ; the main form of inorganic nitrogen in sediments was of ammonia, and the submerged plant cannot change this case
結果表明:總體上,上覆水和間隙水中不同形態氮含量的順序為有機氮氨氮硝態氮;沉積物中可交換態無機氮以氨氮為主,沉水植物的存在並沒有改變這一格局。This article discussed the mechanism of removing ammonia nitrogen with the artificial fast filtration system by analyzing the ability of removing ammonia nitrogen related to the biomass, organic matter and cec ( the total cation exchange capacity ) in different filtration layers
摘要文章通過對不同滲濾層中生物量、有機質、 cec (總陽離子交換容量)和對氨氮去除效果間關系的分析來討淪人工快速滲濾系統去除氨氮的機理。分享友人
