Abstract

The invention discloses continuous remediation equipment for remediating heavy metal composite soil based on biomineralization. The invention relates to the technical field of soil remediation, existing soil remediation equipment is diverse and messy and large in field occupation, the soil remediation is easily influenced by factors such as soil thickness, humidity and biological content, in orderto solve the problems that an existing grinding and screening device is not beneficial to efficient and rapid repairing, the following scheme is provided, the continuous remediation equipment comprises a smashing mechanism, a grinding mechanism, a screening mechanism, a mixing mechanism, a feeding mechanism and a driving mechanism, the grinding mechanism is located below the smashing mechanism, the screening mechanism is located below the grinding mechanism, and the mixing mechanism is located below the screening mechanism. According to the remediation equipment, automatic soil feeding is facilitated, continuous operation is facilitated, soil is smashed, screened and mixed, the thickness, humidity and biological content of the soil can be kept balanced accordingly, overall efficient remediation of the soil is facilitated, and the equipment is high in integration degree, small in occupied area and high in practicability.

Description

technical field

[0001] The invention relates to the technical field of soil remediation, in particular to a continuous remediation device for remediating heavy metal composite soil based on biomineralization. Background technique

[0002] In recent years, with the rapid development of my country's industry, mining, agricultural sewage irrigation, and atmospheric dry and wet deposition have caused heavy metal pollution in the soil. The problem of heavy metal pollution has attracted more and more attention. Studies have shown that heavy metal pollution in soil is mostly compound pollution. The accumulation, migration and transformation of heavy metals in the soil may cause the heavy metal content in crops to exceed the standard, and then endanger human health through the biomagnification of the food chain. Therefore, heavy metal pollution in soil has become an urgent need today. One of the soil environmental problems to be solved. The remediation methods of heavy metals in so...
