采用组合纤维填料作为载体的序批式生物膜反应器进行了生物除磷的试验研究.结果表明,在生物除磷过程中,污水中的VFA总量与溶解磷的吸收量具有较好的相关关系,去除1 mg溶解磷大约需要20 mgVFA-COD;为获得稳定良好的生物除磷效果,COD负荷不能太高,否则过多的有机物进入好氧段将引起非聚磷菌的好氧异养微生物异常增殖,导致聚磷菌被洗出;同时COD负荷也不能太低,还要满足反应器中聚磷菌量能够实现净增长;磷的厌氧释放量和好氧吸收量具有良好的相关性,为提高除磷效率必须保证足够的厌氧磷释放量.图5,表1,参12. 相似文献

The algorithms of the strength, work, modulus and percentage methods have been introduced and discussed in Part Ⅰ and Part Ⅱ of the series papers. As the following, the percentage-function calculation and the frequency-function calculation of the definition method are defined and developed in detail. Meanwhile, the Procedures to fred the tensile parameters are analysed experimentally and involve “ED” being the average values of the corresponding tensile parameters of each bundle tensile curve measured; “EC” being the tensile parameters obtained from the averaged experimental tensile curve; and “TC” being the parameters of the theoretical tensile curve according to the corresponding nominal blend ratio. The theoretical and experimental results indicate that the blend ratio estimated by the definition method from wool/polyester blended fibre bundles has a high correlation with the actual blend ratio though the variables to be known in this method are the most of all the methods and there exist the difficulty to solve fibre bundle tensile behaviour without fibre broken in accuracy and that there are high correlations between the EC and TC data and the tensile parameters should be calculated using the EC method rather than the ED method with the exception of the bundle initial modulus. The relationships between blend ratios and the tensile properties of blended fibre bundles can be used to select the optimum blend ratio of blended tops or yarns. 相似文献
