The united membrane biological reactor(UMBR) was studied for the treatment of some simulate and municipal wastewater. The removal efficiency for COD and turbidity are greater than 80% and 99% respectively. Effluent COD is less than 100 mg/L while turbidity less than 5 The removal of LAS in bath wastewater is greater than 70%. In treatment of dinning hall wastewater, removal of fatty oil is greater than 90%, and its concentration in effluent is less than 5 mg/L. The match of biological reactor and the membrane separation component were calculated. The stable performance of wastewater treatment can be maintained by the optimization of operation conditions and the cleanout of membranes.

Immature embryos from three elite Guizhou waxy maize inbred lines （W21019, B7, and QCL5036） were evaluated for their ability of forming callus and regeneration into plants. Immature embryos harvested at different physiological stages were used as explants to initiate callus on N6 basal medium with 0-3.5 mg L-1 of 2,4-dichlorophenoxy acetic acid （2,4-D）. The concentration of 2,4-D, physiological age of immature embryos and genotype had a significant effect （P0.05） on the percentage of embryogenic callus formed. The optimum 2,4-D concentration for the initiation of embryogenic callus was varied among the waxy maize genotypes from 2.0 mg L-1 （B7 and QCL5036） to 3.0 mg L-1 （W21019）. The shoots were generated from embryogenic callus which were transferred into the regeneration medium supplemented with 0-2.5 mg L-1 of 6-benzylaminopurine （6-BA）. 6-BA in the medium significantly promoted the regeneration of embryogenic callus. Embryogenic size was also an important factor that affected regeneration capacity. 0.6-0.7 cm was proved to be the best size for regeneration from embryogenic callus and the mean number of shoots per primary callus in all genotypes achieved the highest number. The ability of the plant regeneration was also affected by genotype. W21019 had the highest number of shoots formed per primary embryogenic callus. With the optimum condition, the highest mean number of shoots per primary callus was up to 12.13, 5.73, and 3.33 in line W21019, B7, and QCL5036, respectively. The successful regeneration of the two inbred lines provides a basis for development of genetic transformation to improve priority traits such as enhanced insects and drought tolerance.

Because the lack of detailed study of biological decolorization in high salt dye wastewater, it is still difficult to evaluate the biological treatment on high-salinity dye wastewater. The experiments were carried out to study the salt-tolerant bacteria, which is useful in the treatment of high-salinity colored wastewater. Simulated wastewater containing 5-150 g/L salt （NaCI） and 50-2000 mg/L Reactive Brilliant Red K-2BP was treated with three salt-tolerant mixed cultures （CAS, TAS, DSAS）, which were under a gradually acclimated procedure. With the increase of concentrations of salt and dye, the decolorization became low. The abilities of decolorization of dyes wastewater by three mixed cultures （CAS, TAS, DSAS） were studied, CAS and DSAS mixed cultures showed more active for the treatment of high-salinity colored wastewater than TAS mixed cultures. The results suggested that there might be a simple process for the high salt wastewater treatment, which could be incorporated into conventional activated sludge plants.

航天测控仿真软件在每一次航天测控任务中都需要处理大量测控数据,不同参数的计算方法差别很大,在以往的应用中将计算方法以程序代码的形式固定在软件中,使得仿真系统难以进一步提高其可维护性和软件复用度。通过研究以配置文件的形式描述测控参数的计算方法,给出了参数计算灵活配置的设计方案,介绍了参数计算方法原理,软件模块、数据结构和处理算法。在该框架下,数据处理算法与软件代码相分离,使软件开发和具体航天型号任务之间的耦合度降低,增强了软件的可复用性,软件的稳定性也得到了有效保障。利用该方法对遥测参数进行了实验,验证了方法的有效性。
