电混凝法处理电镀废水中的Cu^2+和Zn^2+ 总被引:1,自引:0,他引:1
利用电混凝法处理含Cu^2+和Zn^2+的电镀废水,系统地考察了电解电压、进水pH值、极板间距、电解时间等因素对废水处理效果的影响,确定了最佳的电解条件。实验结果表明,电混凝法处理的电镀废水出水水质较好。当电压为80 V,pH值为5,电解时间30 min,极板间距为10 mm时,处理后的废水中Zn2+浓度为0.36mg/L,去除率达到97.9%,Cu^2+浓度为0.0049 mg/L,去除率达到99.9%,均可达到国家规定的排放标准,且该法运行方便,处理时间短,是较理想的电镀废水处理工艺。 相似文献

To rapidly detect the harmful algae H. akashiwo qualitatively and quantitatively, sequences of the 18S rDNA deduced from H. akashiwo were used for designing species-specific primers, and a RFQ-PCR (Realtime Fluorescent Quantitative Polymerase Chain Reaction) method was developed for quantitative detection of H. akashiwo. Primer H. akashiwo and TaqMan probe were designed, and the specificity of primer was checked with PCR. A calibration curve was constructed with cycle threshold value against visual counted cell number. And the value of the curve was tested with other H. akashiwo samples, which were assayed with both the RFQ- PCR method and visual count under microscope. 相似文献

以rDNA序列为寻找种特异性引物的靶区域,通过分析中肋骨条藻rDNA序列,设计出7套适合用于实时荧光定量PCR方法(RFQ-PCR)的引物与探针,经引物验证,选择Primer6(F/R)进一步分析,对比扩增序列及核酸杂交验证,表明该探针可作为中肋骨条藻特异性探针.最后以Primer6(F/R)和TaqMan6建立了定量检测中肋骨条藻的RFQ-PCR方法,并绘制出了定量检测中肋骨条藻的标准曲线,测定数据用镜检计数进行了验证,证明该方法是准确可靠的. 相似文献
