- Abstract:
- The dairy dung biochar was prepared by using dairy dung as raw material.The degradation of petroleum hydrocarbon contaminated soil in Shenfu waste irrigation area of Shenyang city was studied by the addition of dairy dung biochar.In order to provide technical support for in-situ restoration of oil-hydrocarbon contaminated soil by bovine manure biochar in polluted irrigation area.The results showed that the biochar with dairy dung has a degradative effect on petroleum hydrocarbons in soil.When the preparation temperature of dairy dung biochar was 700 ℃，the amount of dairy dung biochar added was 75 g?kg-1，the initial pH of soil was 9 and the soil temperature was 30 ℃，the petroleum hydrocarbon degradation effect was optimum，and the petroleum hydrocarbon degradation rate was reached 65% or more.These results suggested that biochar dairy dung could be used to actually repair petroleum contaminated soil.
