摘要：
采用生物炭—臭氧工艺对生活污水进行深度处理。通过实验研究分析了该工艺的原理、特点及最佳设计参数。工程实践表明，生物炭—臭氧工艺应用于中水处理中，当臭氧投加量(以污水计)为5g/m3、接触时间为10min时，系统出水水质稳定，不仅得到优质的中水，而且其出水色度、臭味等指标优于中水水质指标，且运行成本较低。

Abstract:
The process of biological carbon-ozone is adopted to treat domestic sewage. The principle, characteristics and the optimal design parameter of the process are analyzed according to experimental results. The results show that when the dosage of ozone is 5 g/m3 wastewater, the contact time is 10 min, the effluent of the system is stable, and the removal rate of COD is higher than 60%. So the process of biological carbon-ozone used in domestic sewage can provide excellent treated water with low cost. At the same time the indexes such as chroma, odour of the effluent are better than that of regenerated water quality indexes.
