Abstract
The waste liquid,which was produced in the process of alkaline foam decontaminating technology,could flow into the existing radioactive waste treatment system after pretreatment due to high levels of organic matter and strong foam capacity.The technique of ozonation was adopted.The orderliness of foam variation and the degradation of organic matter was researched preliminarily in this study.According to the results of experiments,ozone-oxygen mixture could effectively deal with the organic matter.The existence of foam was benefit to the degradation of organic matter.The degradation level of organic matter per gram of ozone and the degradation rate of organic matter were positively followed by the sum volume of foam in the existence of foam.Small aperture aeration set and lower ozone concentration were benefit to the sum volume of foam,the effect of aeration set was obvious,and the effect of ozone mixture flow was small.Different aperture aeration set combined-condition process could increase the sum volume of foam,nevertheless the general effect was not important.With the ozone doses increase,COD of the system became lower and lower,when the degradation rate of COD was 80% with 1.5 ozone surplus coefficients,it increased slowly.关键词
