臭氧和光合细菌联合修复景观水体的研究

Ozone and Photosynthetic Bacteria Combined Remediation of Landscape Research

研究了臭氧和光合细菌联合处理景观水体,结果表明,在控制水体pH值为7.5,按照1 L样品通臭氧25 min(每h产生1.5 g)后,在向其中加入4亿个光合细菌大约静置5 d,景观污水将得到较好的净化效果。根据目前的臭氧制取技术,每制取1 kg臭氧约耗电在20 kW·h,按照每分解1 kg COD需要3 kg的臭氧计算,则每处理1 kg COD需要28元左右。较高的运行费用也是这一技术未能大规模应用的主要因素之一。但是该实验利用臭氧和光合细菌联合处理景观水的方法每处理1 kg COD只需要16.5元左右,大大节约了成本,还提高了效率。因此通过臭氧和光合细菌联合处理技术,净化景观水体中的有机物污染和改善景观水体水质,既节约了成本,又达到了很好的效果。

Joint treatment of lands cape water body by ozone and photosynthetic bacteria was investigated. The results showed that, in the control of water for 7.5 pH, which added to the ozone 25 min （hourly produce 1.5 g）, in which added to four hundreds million the photosynthetic bacteria about standing for 5 days, landscape water could get better purification effect. According to the current ozone technology, preparation of 1 kg per ozone consumption at approximately 20 kW·h, according to every 1 kg COD decomposition of ozone computing needs 3 kg, each treatment takes about 28 RMB 1kg COD. Higher operating cost is one of the main factors of large-scale application of this technology failed. But the experiment combined the use of ozone and photosynthetic bacteria landscape water treatment methods for each treatment took only about 1kg COD 16.5 RMB, significant cost savings, but also improved efficiency. Therefore, through the joint processing of ozone and photosynthetic bacteria, purify organic pollution and improve water landscape water quality. This method not only saved cost, but also achieved good results.
