原油加热炉除尘技术研究

加热炉一般以原油或渣油为燃料，在其运行过程中，大量烟尘沉落在炉体内，烟尘的不断堆积，导致加热炉热效率下降，而吹扫炉膛又使大量烟尘进入环境，造成环境污染，为达到污染物的国家排放标准，就必须对排放的烟尘进行回收治理，根据燃油烟尘易漂浮并沾粘的特点，对几种除尘技术进行了比较，重点推荐了效果较好的滤袋式除尘器技术，提出了现场应用的要求。     

钴—60辐照对石花菜琼胶质量影响

用钴—60辐照处理琼胶成品和干制石花菜。经钴—60辐照的琼胶成品,其凝胶强度均有所下降,其下降率与辐照剂量大小呈正比。石花菜经钴—60辐照后,可使琼胶提取率提高,但过高的辐照剂量,也同时会降低所制取琼胶的凝胶强度。通过适宜剂量的钴60—辐照处理干制石花菜,可提高琼胶提取率3％～5％,且制取的琼胶凝胶强度不受辐照的影响。

Variation in Doubled Haploid Plants of Wheat Obtained through Wheat (Triticum aestivum) × Maize (Zea mays) Crosses

Variation was investigated in 110 doubled haploid (DH) lines of wheat derived from wheat × maize crosses. Field observation revealed visible variations in 15 DH2 lines such as extreme dwarfism, low seed fertility, alteration of spike type and stripes. Six agronomic traits, i.e., heading date, spike number/ plant, culm length, spike length, seed fertility and grain weight were statistically analyzed in the DH2 and DH3 generations. Out of the 88 DH2 lines/DH3 groups, 26 %/64 % showed significant differences from the parental variety in the means of one or more traits. Ranges of the DH3 lines were larger than those of the DH2 lines, except for spike number/plant. Furthermore, analyses of variance within and between DH lines showed the presence of heterogeneity/heterozygosity in the DH2 lines/plants. These results indicated the occurrence of gametoclonal variation in the DH lines. It is considered that most of the variations detected were due to the colchicine treatment rather than to the 2,4-D treatment or in vitro culture.     

Experiment Research on Leachate Treatment of Sanitary Landfill for Municipal Solid Waste

It is difficult to treat landfill leachate in China.Traditional biologic method and physical method always have high expenses,or cann''t reach the discharge standards.The authors use a new biologic method to treat landfill leachate,which is the Wood_microbial System from Japan.The system to be digested by 3 aeration tanks and 1 reaction tank.The comparison combine processed wool_dust broken pieces with the certain grain degree size were throw in the tanks.Dirty and organic matter are in the digest tanks through the aeration reaction and aneration reaction repeatedly.In this experiment the speed of wastewater discharge and oxygen supply has been changed, and the change of biologic system and the effect of pollutant are removed. The optimal treatment condition can be found.The experiment shows that the system has a good result,special for nitrogenous.The BOD is average to do away with the rate to amount to 90%,almost reach the second class or third class for leachate standard.But BOD loading should be not beyond 4 kg/(m 3.d),othrwise,the system will not operate in normally.
