Abstract

The invention discloses an organochlorine pesticide polluted site soil remediation pretreatment device and a method, and relates to the technical field of soil pollution treatment.The device comprises a soil turning device, a vehicle head, a carriage, a cab, a screening device, a conveying device, a high-temperature drying device, a plasma cracking reactor, a fungicide bin and a mixing bin; the soil turning device is rotatably installed at the front end of the vehicle head, the cab is fixedly installed above the vehicle head, and the carriage is fixedly installed behind the vehicle head. According to the device, a movable vehicle is taken as a carrier, soil containing organochlorine is treated. Compare with a conventional soil treatment method, according to the device, soil does not need to be transferred, the transportation cost is saved, the treatment cost of organochlorine pesticide soil is greatly reduced, and the device has a large popularization space.

Description

technical field [0001] The invention relates to the technical field of soil pollution treatment, in particular to a pretreatment device and method for soil remediation of organochlorine pesticide-contaminated sites. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their ...
