Livestock wastewater contains not only high concentration of organics, but also amino acid. This paper studied efficiency of UASB applied in such wastewater, and the influences of environmental and operation conditions on ammoification rate were analyzed. Results show that suitable pH for the bacterium had a wide range from 6. 5 to 8, and pH 7 was the best. A positive correlation was between temperature and ammonification rate, while 38℃ was prefered from an economic point of view. Ammonification rate increased with the influent concentration of increase while there's a contrary situation when the organic load increase.

因畜禽废水除了含有大量的有机物,还含有一定量的氨基酸,因此,研究利用UASB处理畜禽废水,在不同环境条件和工况条件下对氨化率的影响,结果表明:氨化菌适应的pH值范围较宽,在6.5~8.0范围均可以较好的生存,其中以7.0为最佳;温度与氨化率基本成正相关关系,从经济等多种角度考虑,中温阶段38℃为最适宜;氨化率随进水浓度的增加而增加;进水有机负荷越大,氨化率越小。

The pH value in soil was significantly increased in litter aqueous extract of four decomposition stages. The NH+4-N concentration was significantly decreased in soil amended with litter aqueous extract of 10-day decomposition which promoted the growth of Aerobic azotobacter and Ammonifier but inhibited the growth of Aerobic cellulose-decomposer. Available phosphorus concentration was significantly increased and phenolic acid content was significantly decreased in soil amended with litter aqueous extract of 60-day decomposition which inhibited the growth of Aerobic azotobacter but promoted the growth of Aerobic cellulose-decomposer.

The modification occurred in crystal lattice and the restoration effect of annealing are discussed by analyzing the intensity, width and angle of the X-ray diffraction peaks. The H〓 concentration and related structural information are deduced by the evolution of OH〓 absorption spectra with annealing, which offers the experimental proof for further discussion on annealing. The disappearance of the OH〓 absorption peak at 3300cm〓 after annealing indicates that some H〓 of high concentration diffused further into the substrate and the crystal phase changes accordingly.

根据质子交换波导退火前后在OH〓吸收峰特征的变化,推断波导层H〓浓度及相关的结构信息,并对进一步分析退火机制提供了实验依据;由于3300cm〓〓处的吸收峰代表的是立方钙钛矿的HNbO〓结构成分,因此退火后该峰的消失确实说明高浓度区域的H〓继续向波导深度迁移的事实,同时波导区的晶相成分也发生变化。
