Abstract

The invention discloses a contaminated soil biomineralization remediation method based on agricultural waste recycling, which organically combines agricultural waste recycling, heavy metal contaminated soil organic activation and heavy metal biomineralization remediation, and comprises the following specific steps: carrying out deep degradation and comprehensive utilization on agricultural wastesby adopting a multi-stage biodegradation technology; applying an organic acid solution generated by biological fermentation of the agricultural wastes to heavy metal contaminated soil organic activation; applying residues of biological fermentation of the agricultural wastes to culture of mineralized microorganisms and compost maturation; and using the cultured mineralized microorganisms for treating organic activated soil, and returning compost to the field to supplement soil nutrients. The method is suitable for restoration and treatment of heavy metal contaminated cultivated land soil around mining areas and metallogenic zones, has few equipment and facility requirements, is low in treatment cost, good in restoration effect and easy to master, and is beneficial to improvement of miningarea soil, guarantee of mining area agricultural product safety and promotion of mine land harmony and ecological mine construction.

Description

technical field [0001] The invention belongs to the technical field of remediation of heavy metal-contaminated soil, and in particular relates to a biomineralization remediation method of polluted soil based on agricultural waste recycling. Background technique [0002] It is a common problem that the background value of heavy metals in cultivated soil around mining areas and metallogenic belts is high. There are 16 large metallogenic belts in China, which are distributed in more than ten provinces including Sichuan, Yunnan, Guizhou, Xinjiang, Tibet, and Qinghai. The content of heavy metals such as Cd, As, Cr, and Cu in foods such as , fruits, etc. exceeds the standard or is close to the critical value. This is one of the main reasons why there are few famous grain, oil, and fruit brands in this region. It is difficult to develop ecology and green agriculture, and farmers’ income is increased. The problem is becoming more and more prominent. [0003] The existing methods f...
