STUDY ON THE ADVANCED TREATMENT of DYE WASTEWATER USING IRON-CARBON INTERNAL ELECTROLYSIS

采用内电解法对经过生化处理后仍不能达标的印染废水进行深度处理实验,结果表明:当PH维持在4左右,反应时间控制在16MIn左右时,出水投加CA(OH)2约2g/l混凝沉淀,则废水的色度去除率可达87.5%,COd的去除率也可达到50%~80%,处理后的出水完全达到gb8978-1996《污水综合排放标准》一级标准的要求。After being treated by biological method,the dye wastewater can not meet the national standard,so internal electrolysis is used as a follow-up treatment of biochemical treatment.It is analyzed the relationship between removal rate and those factors such as the pH,time and coagulation dosage.When pH=4,Ca(OH)_2 dosage is 2g/L,the decoloring rate can be 87.5% and the removal rate of COD is 50%--80%.The effluent can meet the filst-order of" Waste water Integrated discharge Stand"

全参数全约束优化对钢筋混凝土框架结构设计的造价分析

目前的优化设计一般是将参数简化为一维问题或多维问题,或为全参数优化设计,但约束条件不够充分.针对这些不足,本文建立了更全面的符合工程设计的全参数全约束优化设计模型,利用MATLAB中的fmincon函数进行寻优计算,它可以同各种结构设计软件链接进行参数优化,如本文算例采用了中国建筑设计研究院开发的PKPM软件中已有的内力计算功能.最后,通过算例将各参数对造价影响程度进行分析比较,得出了定性及定量的结论,优化后的结构造价降低显著.与当前的钢筋混凝土框架结构优化设计相比,本文具有较强的实用性、寻优计算快捷等优点

EXPERIMENTAL RESEARCH ON TREATMENT of DOMESTIC WASTEWATER WITH COAGULANTS IN SBR

分别向按A/O方式运行的Sbr反应器中投加一定量氯化铁、硫酸铝、聚合氯化铝,考察这3种金属盐混凝剂强化活性污泥系统处理生活污水的效果。结果表明,这3种混凝剂的化学辅助除磷效果较好,其中,在100Mg/l(以进水量计)的投加量下,投加氯化铁和硫酸铝的强化处理系统对TP的平均去除率比空白组分别提高了65.52%和69.95%。对有机物的去除也有一定强化作用,对氮的强化处理效果不明显,但可提高活性污泥沉降性能。Based on the SBR reactor running with the A/O process,the effect of enhancing activated sludge system adding coagulants(ferric chloride,aluminum sulfate and poly-aluminum chloride)on treating domestic sewage has been studied.Results showed that the three coagulants were efficient in chemical-aid phosphorus removal.The groups separately adding ferric chloride and aluminum sulfate in dose of 100 mg/L(in influent)gained the additional average removal rates of TP about 65.52% and 69.95%.The three coagulants also strengthened the removal of organic matter and had no great influence on the removal of nitrogen,but could improve the performance of sludge settlement

Uptake and Metabolism Kinetics of TBT in Whelk(Thais clavigera)Exposed to Dietary

将牡蛎消化腺分别暴露在1000ng.l-1和100ng.l-1TbT水溶液中4周,然后将染毒的牡蛎消化腺分别投喂疣荔枝螺(THAIS ClAVIgErA)。经过45d的暴露和30d的净化,我们发现雌雄疣荔枝螺的消化和生殖系统能较快地吸收TbT(吸收速率ku=0.004-0.022.d-1),并且其代谢(生物代谢系数bdI=5.59-23.30)和排出速率(净化速率kE=0.024-0.053.d-1)也相对较快,各器官中TbT的代谢产物MbT占了相对较高的比例,因此TbT在食物链传递过程中没有出现生物放大的现象。此外,TbT有逐渐从雌螺消化系统向生殖系统转移的趋势,并且雌螺生殖系统对TbT的吸收和富集能力(ku=0.006-0.022.d-1,生物放大系数bMf=0.181-0.664)要显著强于雄螺(ku=0.004-0.014.d-1,生物放大系数bMf=0.142-0.376),但其代谢和净化速率(bdI=5.59-10.50,kE=0.024-0.025.d-1)却显著低于雄螺(bdI=11.5-12.4,kE=0.031-0.050.d-1),雌螺的生殖系统被认为是TbT转移和富集的潜在靶器官,这对我们今后开展TbT污染的环境监测和评价具有重要的参考价值。Oysters were respectively exposed to 1000 ng·L-1 and 100 ng·L-1 tributyltin(TBT) aqueous for 4 weeks,which was as dietary to feed the female and male Thais clavigera whelks for 45 days.Then these Thais clavigera were depurated for 30 days.The results show that TBT rapidly accumulated in their digestive and reproductive organs(ku=0.004-0.022 d-1).Moreover,elimination and biotransformation of TBT were also rapid(BDI=5.6-23.30,ke=0.024-0.053 d-1).MBT was the dominant metabolite in each tissue.Therefore,bio-magnification of TBT did not occur during the trophic transfer process.Additionally,to females,the mobilization of TBT from digestive to reproductive organs and bioaccumulation of TBT(ku=0.006-0.022 d-1,BMF=0.181-0.664) were more obvious than that of the males.However,lower metabolism and elimination of TBT(BDI=5.6-10.5,ke=0.024-0.025 d-1) in female reproductive organs,which indicated that the reproductive organs of females were the main targets of TBT accumulation.The results are important to the risk assessment of TBT contamination in coastal environments.国家“863”项目No.2007AA09Z126;国家自然科学基金项目No.40476048;20777060;海洋公益性行业科研专项经费;No.20080509

The cultivable bacterial; abundance ranged from 3.70 * 10~2 CFU/mL to 1.42 * 10~3 CFU/ mL, the; total bacterial abundance ranged from 5.12 * 10~5 cells/mL to 1.61 *; 10~6 cells/mL and the bacterial productions varied from 0.03 mg/m~3/h to; 0.40 mg/m~3/h in horizontal distribution. In vertical distribution, the; cultivable bacterial abundance ranged from 1.08 * 10~3 CFU/mL to 9.00 *; 10~3 CFU/mL and the bacterial productions varied from 0.01 mg/m~3/h to; 0.08 mg/m~3/h, respectively. The correlation analysis results showed; that the environmental factors affecting the abundance of total bacteria; and bacterial productivity included temperature, salinity,; nitrate(NO_3-N),silicate (SiO_3-Si), nitrite (NO_2-N),and phosphate; (PO_4-P) (P<0.05). NO_2-N was the main influencing factor to cultivable; bacteria abundance (P < 0.05), while bacterial productivity was highly; correlated with temperature and salinity in vertical distribution of; northern south China sea (P < 0.05). The total bacterial abundance was 2; ~ 3 orders of magnitude higher than cultivable bacteria, suggesting that; there were many uncultured bacterium in surface water of northern south; China sea and bacterial activities in the surface maybe more active than; in the bottom.全球变化与海气交互作用; 国家重点研发计划全球变化及应对专项; 海洋公益性行业科研专
