Abstract

The invention provides a self-accelerated repairing method for petroleum-polluted soil. The self-accelerated repairing method comprises the following steps that mineralized rubbish is prepared, refractory components in the mineralized rubbish is filtered out, aging culture is carried out and drying treatment is carried out so as to obtain the dried mineralized rubbish; crop straws are prepared andcarbonizing is carried out to obtain a biochar material; the biochar material is mixed with the dried mineralized rubbish; micronizing treatment is carried out on the mixture of the biochar materialand the mineralized rubbish so as to obtain the biochar material attached with the micron-scale mineralized rubbish, and the biochar material attached with the micron-scale mineralized rubbish is dissolved in distilled water so as to obtain the biochar solution attached with the mineralized rubbish; and the biochar solution attached with the mineralized rubbish is used for treating the petroleum-polluted soil. The self-accelerated repairing method is high in mineralized rubbish activity, the use amount of the mineralized rubbish is very small, and secondary pollution to the soil is basically avoided; and the self-acceleration repairing method has a certain self-acceleration effect, so that the petroleum treating speed is greatly improved compared with the prior art.

Description

technical field [0001] The invention belongs to the technical field of soil treatment, and relates to a self-accelerating restoration method for petroleum-contaminated soil. Background technique [0002] Soil is one of the main resources for human survival, an important part of the human ecological environment, and a reservoir of material biogeochemical cycles. It is sensitive to the environment. With the increasing dependence of human beings on chemicals, the pollution of organic substances to the environment is also becoming more and more serious. Soil was once thought to be infinitely resistant to human disturbance. In fact, soil is also an environmental element that is very fragile and easily damaged by human activities. Once the soil environment is polluted, it is difficult to control, and the harm is far-reaching. Soil pollution is concealed and delayed. Problems such as air pollution, water pollution, and waste pollution are generally more intuitive and can be dis...
