AI Technical Summary

Technical Problem

It is currently understood that the data on the absorption of heavy metals by waste incineration on specific plants (especially vegetables closely related to humans) is not in-depth enough, and it is difficult to comprehensively evaluate its impact on heavy metal enrichment on soil and plants.

Method used

An experimental platform was designed, including experimental greenhouses, planting and incubator, fly ash placement pallets and spraying devices. The flow regulation device and spraying device simulate natural acid rain, and simulate heavy metal leaching of waste incineration fly ash to the soil under different treatment states. Scenario, verify the enrichment of heavy metals under different treatment methods, pH values ​​and liquid-solid ratios.

Benefits of technology

Quantitative evaluation of the impact of waste incineration fly ash on plants is achieved, which improves the accuracy and reliability of the experiment, and can simulate the heavy metal enrichment of soil and plants in different environments.

Abstract

The utility model discloses an experimental platform for influence of waste incineration fly ash leaching toxicants on plants, which comprises an experimental greenhouse, a planting cultivation box for planting plants is placed in the experimental greenhouse, and a plurality of fly ash placing trays for placing waste incineration fly ash are placed on the top of the planting cultivation box. A plurality of fly ash placing trays are arranged in the experiment greenhouse, a flow adjusting device is arranged between each fly ash placing tray and the planting cultivation box, a spraying device is further arranged in the experiment greenhouse, and the spraying device is used for simulating natural acid rain so as to spray plants in the planting cultivation box and waste incineration fly ash in the fly ash placing trays. According to the application, the heavy metal leaching scene of the waste incineration fly ash on the soil in a non-treated or treated state can be simulated, and the heavy metal enrichment specific content of specific plants planted in the soil is verified by experiments through different fly ash treatment means, different leaching solution pH values and different liquid-solid ratios.
