厌氧—好氧—生物炭系统处理印染废水实例

阐述了采用厌氧水解－好氧生物接触－生物炭吸附氧化工艺处理印染废水的工艺流程、原理、工艺参数及特点。该系统对印染废水ＣＯＤｃｒ及色度的处理取得良好效果，且污泥量少，节省了污泥处理费用。     

化学发光流动注射法测定雨水中过氧化氢

用化学发光流动注射分析装置,将16孔阀连接成异步双流路,以过氧化氢-鲁米诺-钴(Ⅱ)为化学发光体系,建立了快速测定雨水中过氧化氢的方法,最低检测限为0.1ng/ml,在0.1—400ppb范围内有良好的线性关系,相对标准差为0.78—3.03％,每小时可分析480个以上的样品.     

Chorionic villus sampling—short-term versus long-term culture in a subtle 2; 18 translocation

Prenatal diagnosis on chorionic villous tissue was performed for a woman with the karyotype 46,XX,t(2;18)(q32;q12)—a subtle ‘difficult’ translocation. The case illustrates the necessity of good quality cytogenetics for accurate prenatal diagnosis. For chorionic villi this can be obtained only with long-term culture.     

Transabdominal chorionic villus sampling: Analysis of 350 consecutive cases

We report a series of 350 patients submitted to transabdominal chorionic villus sampling (CVS). A technique using two ultrasound-guided needles and a suction pump was used. In most cases, the procedure was performed between 9 and 13 weeks. Twenty-one pregnancies were selectively terminated; nine spontaneous abortions followed the procedure and one fetal loss after 28 weeks was recorded; 153 pregnancies are in progress and 169 delivered fetuses are alive and well. Transabdominal biopsy is a feasible and effective technique for CVS.     

Spontaneous abortion after transcervical chorionic villus sampling: A case report

A case of spontaneous abortion after transcervical CVS is presented. Despite no evidence of bacteria in the vagina and cervix prior to sampling and the prophylactic use of Metronidazole, pathological evidence of chorioamnionitis was found. The implications of this are discussed.     

企业推行HSSE管理体系问题探讨

分析了企业安全管理体系运行中存在的体系文件模板化、体系运行"两张皮"和持续改进低效化等突出问题,探讨了企业推行HSSE管理体系的对策:提升企业最高管理层的引领力、部门的协同力和基层的执行力,发挥安全文化的影响力、渗透力,同时,要进一步细化体系运行有效性评价指标,做实内部审核和管理评审。     

泡沫分离--臭氧消毒装置的水处理效果研究

对闭合循环水产养殖系统中泡沫分离—臭氧消毒装置及泡沫分离装置的水处理效果进行研究。结果表明,泡沫分离—臭氧消毒装置对养殖水体中异养细菌去除率为93.58％,NH_4~ -N、NO_2~--N去除率分别为39.00％、38.10％,能明显提高水体pH和DO,对COD的去除效果不明显;连续运行24h,能有效控制养殖水体中的NO_2~--N浓度和异养细菌数量。泡沫分离装置出水口比进水口的NH_4~ -N、NO_2~--N和COD分别降低42.45％、24.71％、11.00％,能明显提高出水pH和DO;连续运行24h,对养殖系统中的NH_4~ -N和NO_2~--N有一定的处理效果。

Long-term nitrogen and phosphorus removal,shifts of functional bacteria and fate of resistance genes in bioretention systems under sulfamethoxazole stress

To understand the long-term performance of bioretention systems under sulfamethoxazole (SMX) stress, an unplanted bioretention system (BRS) and two modified BRSs with coconut-shell activated carbon (CAC) and CAC/zero-valent-iron (Fe0) granules (CAC-BRS and Fe/CAC-BRS) were established. Both CAC-BRS and Fe/CAC-BRS significantly outperformed BRS in removing total nitrogen (TN)(CAC-BRS:82.48%; Fe/CAC-BRS:78.08%; BRS:47.51%), total phosphorous (TP)(CAC-BRS:79.36%; Fe/CAC-BRS:98.26%; BRS:41.99%),and...
