查询词典 uranium oxide

5 kinds of paddy soil treatments were studied, then each microorganism biocoenosis was extracted or bacterial strain was dissociated. Artificial synthesis ferric oxide was considered only electron acceptor, which inoculated soil leaching liquor or bacterial strain with reduction function in mineral salt culture system under anaerobic constant temperature condition. After different temperature treatments towards leaching liquor, temperature was controlled and AQDS added into culture system in order to discuss the effect of temperature and AQDS on ferric oxide microorganism reduction process.

Uses most early the ferric oxide sweetening agent for the bog ore and the artificial ferric oxide, for increases its factor of porosity, the sweetening agent take the sawdust as the stopping, again sprays the right amount water and the few white lime, sun-dries repeatedly makes, its PH value is generally about 8-9, this kind of sweetening agent desulphurization efficiency is low, must outside the tower regenerate, the regeneration difficulty, then is substituted for soon by other sweetening agents.

最早使用的氧化铁脱硫剂为沼铁矿和人工氧化铁，为增加其孔隙率，脱硫剂以木屑为填充料，再喷洒适量的水和少量熟石灰，反复翻晒制成，其PH值一般为8-9左右，该种脱硫剂脱硫效率较低，必须塔外再生，再生困难，不久便被其他脱硫剂所取代。
