Difficult separation of ,oil,–solid phase and high fine content of the recovered ,oil, were two problems in the ,treatment, of oily ,sludge, from the tank bottom by the hot water-based extraction process. To solve the problems, one technology with “ball milling + ozone-catalyzed oxidation” as the core was studied, and the process parameters of ball milling and ozone-catalyzed oxidation were respectively optimized.

20/1/2020, · As shown in Fig. 2(b), at the beginning, the residual ,oil, rate of the ,sludge, gradually decreased from 1.87% to 0.80% as the agitation intensity increased. And then, the residual ,oil, rate of the ,sludge, slightly increased as the agitation intensity increased. When the stirring strength was 350 r/min, the ,sludge, residual ,oil, rate was at the minimum.

This ,sludge,, the main feature of which is high water content, is the flocculated ,sludge, after sewage ,treatment, in flotation. Ultimate analysis results showed that this kind of oily ,sludge, has high nitrogen and sulfur contents. Usually, Nitrogen comes from protein in ,sludge, and nitrogen compounds in crude ,oil,, such as pyridine and indole.
