The excreta of humans and land animals contain soluble refractory organic matter. After countless generations in water, some of them took the risk to ascend and started the lengthy evolutionary process of terrestrial animals. 人和陆生动物排泄物含有可溶的难处理有机物质。它们在水里生活了无数时代后,才冒险登陆,开展了陆生动物悠长缓慢的演化历程。
The excreta of humans and land animals contain soluble refractory organic matter. 人和陆生动物排泄物含有可溶的难处理有机物质。
The results presented in this study show that the refractory nature of this gold ore was originated in gold fine encapsulated by iron sulfide minerals, but organic carbonaceous and clay matter in ores have not effect on leaching of gold. 研究表明,该金矿的难浸特性是因为金包裹于含铁硫化矿物中,有机炭质物和粘土矿物对金浸出影响甚微。
Conclusion MTC is difficult to diagnose before operation, but the following information can help to diagonse: ① swelling of cervical lymph node accompanied by refractory but noninflammatory diarrhea, no matter whether the mass of thyroid could be palpated or not; 结论MTC术前诊断困难,但有下列情况应考虑本病:不论甲状腺是否触及肿块,但有淋巴结肿大伴有顽固性非炎性腹泻者;
It's necessary to use other method for degrading nitrobenzene which is a refractory organic matter, self-made DSA ( Dimensionally Stable Anodes)-typed an-odes, with special technology have been employed in electrochemical catalytic system to treat nitrobenzene waste water. 用新兴的电化学催化系统,采用特殊工艺自制的DSA类电极作为阳极,对模拟硝基苯废水进行了降解处理。
The stabilization pond process treatments urban and industrial waste water, investment and operating costs is low, work is stable and reliable, management is easy, and this process can remove effective a variety of refractory organic matter. 稳定塘工艺处理城市和工业废水具有投资省、运转费用低、工作稳定可靠、管理方便,能有效的去除多种难降解有机物的优点。
Increasingly stringent environmental protection, water treatment refractory organic matter is becoming increasingly obvious. 环境保护日益严格,水中难降解有机物的治理问题日益显著。
So the adapting and cultivating of salt-tolerant micro-organisms should be controlled strictly. ② The key of excellent performance biological treatment process of effluents containing high salinity and refractory biodegradable organic matter is controlling the salinity. 应严格控制耐盐微生物的驯化培养过程;②盐度控制是高盐难降解废水生物处理工艺成功运行的关键。
To solve this problem, adding a internal reflux within the reactor is proposed, which would enhance the flushing of the lower part of reactor and accelerate the degradation of refractory organic matter. 针对这一问题,建议对反应器添加内回流,增强滤池中下部气水冲刷作用以及加速难降解有机物的降解。
