An integrated device for remediating farmland organically polluted soil

Abstract

The invention discloses an integrated device for repairing farmland organic polluted soil, and the integrated device mainly comprises a soil treatment device, a thermal desorption device and a waste gas treatment device. The soil treatment device is connected with the thermal desorption device through a pipeline, and the waste gas treatment device is respectively connected with thermal desorptiondevice and the soil treatment device through pipelines; the soil treatment device comprises a crushing shell, a crushing main shaft, a first crushing disc, a second crushing disc and a third crushingdisc; the thermal desorption device comprises a heating pipe and a rotating main shaft; the waste gas treatment device comprises a device shell, an air inlet A, an air outlet A, an air inlet B and anair outlet B. Through the combined action of the soil treatment device, the thermal desorption device and the waste gas treatment device, the integrated device has high soil remediation efficiency, energy conservation and low consumption, and can effectively utilize waste gases generated by thermal desorption in multiple effects.

Description

technical field [0001] The invention relates to the technical field of agricultural non-point source treatment, in particular to an integrated device for repairing farmland organically polluted soil. Background technique [0002] Due to the agricultural use of sludge, the stacking of agricultural solid waste and the widespread use of pesticides, organic pollutants such as phthalates, polycyclic aromatic hydrocarbons, organochlorine and organophosphorus pesticides directly or indirectly enter the soil environment, and due to fat solubility It is easy to be adsorbed by soil particles and remain in the soil for a long time. Many of these organic substances are carcinogenic, teratogenic or mutagenic substances. Residing in the soil can not only reduce or even eliminate crop yields, but also enter the food chain through plants or animals , has a serious impact on human survival and health, so the remediation research and treatment technology development of soil organic pollutants...

Problems solved by technology

[0003] Farmland organic pollution in agricultural non-point source pollution Soil pollution has always been the top priority in the treatment of agricultural non-point source pollution. The quality of the soil is related to the quality of the plants. However, in the prior art, the device integration degree is low when treating the soil, resulting in equipment It is difficult to spread and invest in a large range. At the same time, the thermal desorption efficiency of the equipment used in the prior art is still low, the soil is not stirred sufficiently, and the heating is uneven, which all affect the effect of organically polluted soil in the farmland. Therefore, , in order to improve the remediation effect of farmland organically polluted soil, a new type of integrated device is needed to solve these problems
