1.The result shows that the COD removal reaches about 56% on the condition of pressure 0.1MPa, aeration flux 10wm, aeration time 6-8h and mixed liquor suspended solids concentration 3.0-5.0g/L.
加压接触氧化处理研究了进水混合后COD_(Cr)浓度约为1800mg／L时，压力、曝气时间、曝气量等因素对COD去除效果的影响，结果表明在压力0.1-0.12MPa、曝气时间6-8h、曝气量7.5-10wm时，COD去除率约为67％。收藏指正
2.The experiment results showed that the removal efficiency of stickies achieves 83.4% at Vg=0.4 m3/h(Vg means gas flux) and more than half of the ash can be removed.
实验发现,即使在空气贮藏量较低、浮选柱气体流量0.4m3/h时,胶黏物去除率也能够达到83.4%、灰分去除率在50%以上。收藏指正
3.Abstract: There are offered many ways how to improve work of a spark plug.But one of the m ost important problems has not been solved yet.This is a thermal mode operation of a spark plug.The ideal spark plug should be instantly heated at the moment of occurrence of a spark and instantly cooled down in expectation of the foll owing electrical pulse.Thus it balances between preservation of heat for self?c leaning from scale and its removal in avoidance self?ignition.In this article a uthor managed for this time to offer a spark plug with capability “self?regula tion” of heat flux removed from a zone of ignition.Essence of the offer is a t ip，which is transparent for heat flux.It is produced from single crystal of sap phire.
文摘:在如何提高火花塞的工作质量方面有多种方法,但是其中最重要的一个问题还没有得到解决,那就是火花塞工作的热学模型问题.理想的火花塞应该能在点火的瞬间被立刻加热,并且在接下来的电脉冲过程中迅速冷却,由此在热量的存储与散发之间取得平衡,以避免自点火.本文力图展示一种具有自动调节源于点火区域热流能力的火花塞,其技术的关键是顶部绝缘体材料,它是由蓝宝石单晶制作,而非传统的氧化铝陶瓷.收藏指正
4.After 40 days continuous operation under the condition of HRT 4h, flux of SFDM 20. 8 Lm-2h-1, MLSS 4000mg/L and water head drop 9mm, no SS was detected in the effluence and its turbidity being les than 5 NTU and removal rates of COD and NH3-N being about 80% and 87.5% respectively. Its average removal rate of organism was 18.6%.
在HRT为4h. ,膜通量为20.8Lm-2h-1,MLSS为4000mg／L左右时,系统稳定运行40d里,出水水头压差保持在9mm左右,出水的SS未检出,浊度均小于5NTU,氨氮的去除率保持在80％以上,COD平均去除率为87.5％,膜分离对有机物的平均去除率为18.6％.收藏指正
5.The result illustrated that, in the condition of 5 hours HRT and at flux of 13.9 L/(m~2·h),16.7 L/(m~2·h),20.8 L/(m~2·h), the removal efficiency of COD and SS in the system was 90% and 100%, respectively.
试验结果表明:在水力停留时间HRT为5h,膜通量分别为13.9 L/(m~2·h)、16.7 L/(m~2·h)、20.8 L/(m~2·h)三种情况下,系统对COD的去除率均可以达到90%以上,且出水中均未检测到SS;收藏指正
