生物表面活性剂及多环芳烃降解菌强化堆肥处理污染泥土
A Composting Method Using a Biosurfactant and Polycyclic Aromatic Hydrocarbons Degrading Bacteria to Decontaminate Soil

Summary

The degradation of contaminant, PAHs is very ineffective and slow. Beside, during soil composting process, the toxicity of PAHs significantly increased with its increased molecular weight. More difficulty, the biodegradation of molecules containing five or more benzene rings of PAHs molecules is very hard during soil remediation process. It introduces an ectopic contaminated soil bioremediation technology, which is to add the organic substances, biosurfactant or its bacteria or polycyclic aromatic hydrocarbons (PAHs) degrading bacteria to facilitate the degradation and removal of PAHs contaminants in soil.

Technology Benefits

Speed up the soil decontamination rate, simple and direct process

Technology Application

Decontaminate Soil

Detailed Technology Description

It introduces an ectopic contaminated soil bioremediation technology, which is to add the organic substances, biosurfactant or its bacteria or polycyclic aromatic hydrocarbons (PAHs) degrading bacteria to facilitate the degradation and removal of PAHs contaminants in soil.
