| 中文摘要 |
| 利用活性污泥微生物膜制成BOD生物传感器,发现在经过一定时间高压静电处理后的缓冲液中,活性污泥降解有机物的能力可提高20%以上,同一电压不同处理时间对微生物降解能力影响不同。处理时间过短或过长对微生物降解能力增加的影响都不明显。不同电压达到良好处理效果所需时间不同,较低电压所需时间较长,5000V时约需6.0h(信号响应达到初始值的124%),而7000V时约为4.0h.结果表明,高压静电处理并接种活性污泥,有望成为处理某些有机物废水的有效方法。 |
| 英文摘要 |
| The microorganisms extracted from activated sludge were selected as the sensitive material to make a BOD biosensor for monitoring the metabolic ability of themselves in high-voltage electrostatic treated water(HVETW).The oxygen utilization rating of the microorganisms which operated in such an aqueous media for appropriate time,could be promoted by at least 20%. At the same working high-voltage,this effect depended on how long the water was treated.The water treated for too long a time would lead to the negative effects.At 5000.V,it took about 6.0 h for the microorganisms to obtain the maximum oxygen utilization rating,whereas it did about 4.0 h at 7000.V.This discovery might offer a great potential for improving the new waste water disposal techniques. |
