采用迷宫斜板技术与重力式无阀过滤器处理矿井水

兖州矿业集团公司鲍店煤矿是我国自行设计的全综采机械化、特大型现代化矿井,1986年建成投产。在煤矿生产过程中,由于巷道揭露和采空区塌陷波及到水源,为保障煤矿的安全生产,在井下-430水平设有中央泵房,将矿井水排到地面。矿井水涌水量为450～700m~3/h,矿井水中SS为140～360mg/L,CODcr120～320mg/L,pH值8.0～9.0。 随着矿井的不断发展,对水的需求迅速增长,地下水却日益匾乏。为此,经多次酝酿,在对多种技术方案论证的基础上,结合矿的实际情况,选择

Performance of biotrickling filters packed with structured or cubic polyurethane sponges for VOC removal

Two identical bench-scale biotrickling filters (BTFs), BTF 1 and BTF 2, were evaluated for toluene removal at various gas empty bed contact times (EBCTs) and organic loadings. BTF 1 and BTF 2 were packed with structured and cubic synthetic polyurethane sponges, respectively. At a constant toluene loading of 16 g/(m3 hr), toluene removal efficiencies decreased from 98.8% to 64.3% for BTF 1 and from 98.4% to 74.1% for BTF 2 as gas EBCT decreased from 30 to 5 sec. When the toluene loading increased from 35 to 140 g/(m3 hr) at a gas EBCT of 30 sec, the removal efficiencies decreased from 99.1% to 77.4% for BTF 1 and from 99.0% to 81.5% for BTF 2. The pressure drop for both BTFs increased with increased air flow rate, and did not significantly vary while the toluene loading was increased under similar operation conditions. BTF 1 and BTF 2 could start up successfully within 19 and 27 days, respectively, when packed with fresh sponge media, and the performances could be restored in 3–7 days after biomass was removed and wasted from the media. BTF 2 displayed higher removal efficiency even under shorter EBCT or higher loading rate than BTF1 when other operation conditions were similar, while it showed lower pressure drop than BTF 1 during the whole period of operation. These results demonstrated that both BTFs could treat waste gas containing toluene effectively.     

含铀四氯化碳废液(蒸发)处理废气对过滤系统影响

实验研究了含铀四氯化碳废液蒸发过程对过滤器性能的影响及其蒸馏处理技术途径。实验结果表明:采用立式旋转蒸发器,控制温度90℃、转速40～50r/min,蒸馏完全,铀近100%滞留于蒸残液中;CCl4蒸发处理会降低滤料的过滤效率、增大滤料阻力,从而影响过滤器整体性能。
