Preparation method and using method of novel biological soil remediation agent

Abstract

The invention relates to a preparation method of a novel biological soil remediation agent. The method comprises the following steps: (1) compounding and mixing four bacteria, including anaerobic spore-bearing bacilli TIBCC1.002, micrococcus luteus TCCC23001, pseudomonas fluorescens AS1.867, Burkholderia cepacia NKCCMRNK.T2-2 according to the weight part ratio of (3-6) to (2-5) to (1-4) to (1-3) to form a compound bacterium solution, adding the compound bacterium solution according to the weight ratio of 1%-5% into active sludge, and biologically enhancing the active sludge; (2) filtering biogas slurry by a hollow fiber membrane with the pore diameter of 0.1-0.2 micron so as to obtain waste biogas slurry residues; (3) mixing the biologically enhanced active sludge with the waste biogas slurry residues according to the weight part ratio of (3-9) to (1-5), and stirring uniformly to form the novel biological soil remediation agent. The invention provides another approach for the recycling of the residual sludge and biogas slurry, so that not only can the polluted soil be remediated effectively, but also the load to the environment pollution by the residual sludge and the waste biogas slurry residues can be relieved to a certain extent; the preparation method has relatively high practical application value.

AI Technical Summary

Benefits of technology

This patented process involves preparing a novel type of material called “biomass” from renewable sources like sewage sludes (BWS). By mixing these materials together, they become better at decompositing harmful chemical components found within their constituents while reducing others outcomes such as water quality issues associated with land disposal activities. These mixtures are then used to create various types of products including fertilizers and pesticides through processes similar to traditional methods involving decomposition of pigments in dried clay mineral solids. Overall, this approach helps improve the efficiency and sustainability of natural resources utilization.

Problems solved by technology

This patented technical problem addressed in the patents relates to improving the efficiency of removing harmful substances from soil environments while minimizing their impact on human health and natural resources. Current treatments involve either physically or chemically reactive materials that require specialized facilities and trained staff, leading to increased expenses and limited applicability within developing regions due to lack of adequate infrastructure. Additionally, there exist concerns about how these techniques may be applied across different geographies and regimes where they could lead to negative effects on local populations.
