A plant extraction device for lead in the soil around heavy metal enterprises

Abstract

The invention discloses a plant extraction device for lead in the surrounding soil of a heavy metal enterprise, comprising a device main body, a signal converter, an ion selective electrode and an extrusion head, the surface of the device main body is provided with a display screen, and the device main body A signal converter is provided inside, and the top of the main body of the device is fixedly connected to the extraction assembly, which includes a housing, a bottom plate, a metal column, a groove and a guide tube, and the bottom of the housing is provided with an ion-selective electrode, Sensitive membranes are symmetrically distributed on the top of the ion-selective electrode, and the top of the housing is fixedly connected to a flip cover, and an extrusion head is arranged inside the flip cover. This plant extraction device for lead in the soil around heavy metal enterprises can squeeze out the essence inside the plant sample through the equipped extraction components, and then the essence will flow into the sensitive film along the groove for detection, and obtain accurate Lead content data for subsequent phytoremediation, improving the efficiency of remediation.

Description

technical field [0001] The invention relates to the technical field of lead control, in particular to a plant extraction device for lead in the soil around heavy metal enterprises. Background technique [0002] Lead is a viscous metal, which is easy to form stable substances with soil organic matter and iron-manganese oxides. The soil is widely distributed and has a strong accumulation capacity. It is mainly distributed in the soil layer above 20 cm, which has a great impact on vegetable planting. Human breathing and other ways into the human body, endangering human health. [0003] Most of the lead detection and treatment devices currently on the market are to extract the land and plant samples inside the land, and then test them. Only after knowing the lead content inside can the corresponding treatment be carried out. The operation process is cumbersome and requires a lot of time. It takes a long time, and at the same time, it is impossible to directly obtain lead-conta...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a plant extraction device for lead in the surrounding soil of heavy metal enterprises, which solves the problem that most of the lead detection and control devices on the market extract the land and plant samples inside the land, and then It is tested to know the internal lead content before the corresponding treatment can be carried out. The operation process is cumbersome and takes a long time. At the same time, it is impossible to directly obtain the information of lead content in the polluted land environment. The limitations of the more troublesome problem
