Many polycyclic hydrocarbons (PAH) in oily silt have teratogenicity, mutagenicity and carcinogenicity, and bring serious damage to human health through direct and indirect approaches. Polycyclic aromatic hydrocarbons can mainly cause skin cancer, lung cancer and stomach cancer, the main harm parts of the polycyclic aromatic hydrocarbons to human bodies are respiratory tracts and skins, and people can cause acute or chronic injury when being in the polycyclic aromatic hydrocarbon polluted environment for a long time. After entering farmland, some harmful substances are absorbed by crops and enter human bodies, animals and plants through food chains, so that various diseases occur and the health of human beings is threatened. Meanwhile, the polymer-containing waste in the oily sediment is stacked in the open air, so that not only is the resource waste caused, but also the soil and the atmosphere are polluted, and more seriously, the migration and the permeation of petroleum hydrocarbon in the soil pollute underground water, so that an aquatic ecosystem is damaged.
Therefore, the treatment and recovery operation of the oily sediment is very necessary, and the treatment steps of the oily sediment in the prior art are divided into five parts: solid-liquid separation, oil-water separation, high-pressure dehydration, crushing and washing of recoverable substances, thermal shrinkage granulation, recovery of tobacco pulp, dust removal and discharge. The solid-liquid separation operation steps are as follows:
firstly, a trowel loader cuts off large waste materials, the trowel loader manually loads the waste materials into a hopper, and the hopper feeds aging oil into a rotary picking cage;
washing off particles on the aging oil, washing by water nozzles in front and back, pushing from front to back, and hanging plastics by teeth;
step three, heating the water in the separation to 80-90 ℃ through a heating chamber, discharging gas pollutants such as smoke dust and the like evaporated in the waste material when meeting heat, and aerating in a rotary picking cage by an aerator to float oil in the waste material;
and step four, pouring the waste which is not recycled after cleaning into a sorting room, and sorting different types of waste by sorting personnel.
In the prior operation of the oily sediment, the operation is carried out manually in the first step and the fourth step, and more harmful substances exist in the oily sediment.
