AI Technical Summary

Technical Problem

In existing microbial remediation technologies, microorganisms are difficult to release slowly and continuously in the soil, resulting in rapid decline in their numbers. Frequent addition is required, making the operation complex and the remediation efficiency unstable, and it is difficult to adapt to complex soil environments.

Method used

A soil remediation system based on microbial remediation is designed, which uses a biodegradable substrate and a limiting mechanism to slowly release microorganisms through filter holes. Combined with a stainless steel ring and a pre-embedded cover, it ensures that the microorganisms are evenly distributed and stably activated in the soil.

Benefits of technology

This enables the slow and continuous release of microorganisms, reduces the frequency of operations, improves remediation efficiency and the system's environmental adaptability, and reduces labor and time costs.

Abstract

This invention proposes a soil remediation system based on microbial remediation, comprising a ring body. A pre-embedded cover is fixedly installed on the inner side of the ring body, and a top cover is bolted to the top of the pre-embedded cover. A through groove is formed in the middle of the inner side of the top cover. During the application of this device, the decomposable substrate of the microbial carrier group is key in the slow release of microorganisms. The decomposable substrate slowly decomposes upon contact with water, carrying the dried microbial substrate. After the pre-embedded cover is buried in the soil, water seeps in through the filter holes and comes into contact with the substrate. Upon contact with the substrate, the substrate gradually decomposes from the outside to the inside and from the bottom to the top, releasing the dried microbial substrate and activating it. The microorganisms enter the soil through the holes. This mechanism avoids short-term decline of microorganisms, maintains an effective number, reduces the frequency of replenishment, reduces operational complexity, and can better adapt to the soil environment, fully exert the remediation effect on heavy metals, improve the remediation effect, and enhance the system's environmental adaptability.
