Polluted soil environment-friendly treatment screening device and using method thereof

Abstract

The invention relates to the technical field of soil treatment, in particular to a polluted soil environment-friendly treatment screening device and a using method thereof. The invention aims to solve the problems of incomplete soil crushing and too single disinfection and sterilization means. In order to solve the technical problem, the polluted soil environment-friendly treatment screening device is composed of a grinding mechanism and a disinfection and sterilization mechanism, a feeding pipeline, a first steel plate and a second steel plate are arranged, and large soil blocks are prevented from slipping between two rolling rollers. Therefore, the labor force for manually crushing large soil blocks is reduced; by arranging an ultraviolet germicidal lamp, a medicament box and an ozone generator, crushed soil can be further disinfected and sterilized, and the survival probability of agricultural plants is increased; and by arranging a first vibration motor, a second vibration motor, a third vibration motor and an electric heating plate, soil is heated and prevented from being coagulated into blocks, and later smashing is facilitated.

Description

technical field [0001] The invention relates to a screening device for environmental protection treatment of polluted soil, in particular to a screening device for environmental protection treatment of polluted soil and a use method thereof, belonging to the technical field of soil treatment. Background technique [0002] The pollutants produced by human activities enter the soil and accumulate to a certain extent, causing soil quality to deteriorate, and then causing some indicators in crops to exceed the national standard, which is called soil pollution. There are various ways for pollutants to enter the soil, including Exhaust gas, the pollutants contained in the exhaust gas, especially particulate matter, settle to the ground and enter the soil under the action of gravity, as well as waste water, which carries a large amount of pollutants into the soil, followed by pollutants in the solid waste discharged from the factory Directly into the soil or its seepage into the so...

AI Technical Summary

Problems solved by technology

In the process of realizing the scheme, the inventor found that the following problems in the prior art have not been well resolved: 1. The soil is not thoroughly crushed, and the larger soil clods need to be manually crushed into smaller ones when they enter it for crushing. 2. The disinfection and sterilization methods are too simple to effectively kill the virus pests in the soil; 3. The existing devices cannot screen out the stones and ores in the soil, and cannot loosen the soil
