| 摘 要： | 文章研究了臭氧氧化在污泥减量化中的效果,考察了氧化时间、污泥初始浓度和臭氧投加量等影响因素。结果表明采用臭氧氧化法不仅能使污泥减量,而且废水处理后可生化性显著提高。氧化时间及臭氧投加量增加,总COD去除率和可生化性也随之提高。

| Abstract: | Effect of ozonation in the sludge reduction and affecting factors such as oxidation time,initial concentration of sludge and ozone dosage were studied. Results showed that ozonation can effectively reduce sludge production and the biodegradability of treated sludge was significantly enhanced. With the longer oxidation time and more ozone dosage,COD removal efficiency and biodegradability also increased. |
