Determination of arsenic in grain and soil by hydride nondispersive atomic fluorescence method

Quantity of trace arsenic in grain and soil was determined by hydride nondispersive atomic fluorescence method.Optimum conditions of measurement were selected in the experiment including the pH of the medium, reductive agent, the concentration and flowing velocity of KBH4, rate of carrier gas and atomized temperature. The reference sample of rice C was determined and the linear relationship of the calibration curve was plotted, indicating that the method was highly precise. In the experiment of recovery rate, the method was quite satisfactory.Based on the determination of hundreds of samples, it is proved that atomic fluorescence method is rapid, sensitive and low in interference. It is very efficient on determination of trace arsenic in soils and grains, especially in grains.

Removal of high concentrated ammonia nitrogen from landfill leachate by landfilled waste layer

The landfill of municipal solid waste(MSW) could be regarded as denitrification reactor and involved in ammonia nitrogen biological removal process. In this research, the process was applied to municipal solid waste collected in Shanghai, China, which was characterized by high food waste content. The NH4^ removal efficiency in the system of SBR nitrifying reactor followed by fresh and matured landfilled waste layer in series was studied. In the nitrifying reactor, above 90% of NH4^ in leachate was oxidized to NO2^- and NO3^- . Then high concentrated NO2^- and NO3^- were removed in the way of denitrification process in fresh landfilled waste layer. At the same time, degradation of fresh landfilled waste was accelerated. Up to the day 120, 136.5 gC/(kg dry waste) and 17.9 gN/(kg dry waste) were converted from waste layer. It accounted for 50.15 % and 86.89 % of the total carbon and nitrogen content of preliminary fresh waste, which was 4.42 times and 5.17 times higher than that of reference column respectively. After filtering through matured landfilled waste, BOD5 concentration in leachate dropped to below 100 mg/L, which would not affect following nitrification adversely. Because the matured landfilled waste acted as a well methanogenic reactor, 23% of carbon produced accumulatively from fresh landfilled waste degradation was converted into CH4.

城市生活垃圾理化性质的动态特性分析

对太原市城市生活垃圾的组成、化学元素及重金属等进行了1年(每月2次)共24次的分析。结果表明,太原市生活垃圾的组成在焚烧过程中,能产生低位热值(Q低)的有机物占(44.28±2.24)％,不产生低位热值的无机物占(13.94±2.01)％,混合物(破碎的动植物碎片及粘附在其上面的灰、土、砂)占(43.36±8.67)％。垃圾中可燃物比例较高,水分含量较低,有利于焚烧和热解,低位热值(Q低)平均值为(5590.8±1252.3)kJ/kg,但低位热值随季节变化较大。垃圾中化学元素硫(S)、氯(Cl)、氮(N)、氢(H)、碳(C)、氧(O)的年平均值分别为(0.20±0.13)％、(0.48±0.11)％、(0.87±0.18)％、(2.56±0.76)％、(30.78±4.06)％、(16.42±5.17)％,与其他城市相比,S、N、Cl的含量较高。垃圾中的重金属铅(Pb)、镉(Cd)的年平均值分别为41.94mg/Kg和1.806mg/kg;汞(Hg)含量变化较大。焚烧后的灰渣中,Pb部分挥发,Cd得到富集,但几乎无Hg检出。
