Problems solved by technology
[0003] Among the published patents, there are very few patents on the use of garden waste and lawn plants to repair petroleum hydrocarbon-contaminated soil. Generally, bermudagrass, tall fescue, ryegrass, Sudan grass and other plants are used for restoration, and plant waste is regarded as garbage Discarding not only causes waste of resources but also poses environmental risks

The invention provides a device for repairing petroleum hydrocarbon contaminated soil through green waste. The device comprises a treatment device. A bottom plate of the treatment device is a PVC perforated plate, and side plates on four sides of the treatment device are PVC plates. A gravel layer, a loofah sponge layer, a tree pruning layer, a grass clippings layer, a coal cinder layer, a non-woven fabric layer and a mixed layer are sequentially laid in the treatment device from bottom to top. Lawn plants are sown in the mixed layer. A ventilating dry pipe is distributed in the gravel layer, and the air inlet end is provided with a draught fan. A plurality of ventilating branch pipes are arranged on the ventilating dry pipe. The ventilating branch pipes sequentially penetrate through the gravel layer, the loofah sponge layer, the tree pruning layer, the grass clippings layer, the coal cinder layer, the non-woven fabric layer and the mixed layer. A plurality of vent holes are formed in the ventilating branch pipes. Non-woven fabric wraps the positions, provided with the vent holes, of the ventilating branch pipes. Air outlets of the ventilating branch pipes are each provided with a sealing plug. The ventilating layered structures are sequentially laid, soil petroleum hydrocarbon is absorbed, transported and metabolized through lawn plants, and petroleum hydrocarbon contaminated soil is repaired through the transformation and metabolism effects of rhizosphere microorganisms.
Description
technical field [0001] The invention relates to the fields of solid waste disposal and utilization and soil pollution restoration, and more specifically relates to a device and method for repairing petroleum hydrocarbon-contaminated soil by using garden waste. Background technique [0002] Oil spills and leaks that occur during oil extraction, storage, transportation, refining and processing will produce crude oil that falls on the ground, causing serious pollution to the soil. Among the remediation methods of petroleum hydrocarbon-contaminated soil, phytoremediation is simple in operation, less in investment, beautifies the environment and has no secondary pollution. Plants themselves can absorb, transform, enrich, fix and passivate pollutants, and can promote the degradation of pollutants by rhizosphere microorganisms. Studies have shown that, similar to adding exogenous petroleum-degrading bacteria, adding appropriate conditioning agents to stimulate indigenous microorga...
