一. Wastewater Treatment

1. Decomposition of Organic Pollutants

1.1 Bacillus subtilis:

This bacterium has strong decomposition capabilities and can effectively break down organic matter in wastewater, such as proteins, carbohydrates, and fats. It secretes various extracellular enzymes that decompose large organic molecules into smaller ones, making them easier to remove in subsequent treatment stages. In wastewater treatment plants, Bacillus subtilis formulations can be added in certain proportions to primary settling tanks or aeration tanks to reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD), thereby reducing the burden on subsequent treatment processes.

1.2 EM Composite Bacteria:

EM composite bacteria, composed of various beneficial microorganisms, also play a significant role in wastewater treatment. They work synergistically to accelerate the decomposition of organic matter in wastewater and promote the cycling and transformation of nutrients such as nitrogen and phosphorus. For example, in small-scale wastewater treatment facilities, regular application of EM composite bacterial solution can convert harmful substances like ammonia nitrogen into harmless forms such as nitrogen gas, improving the purification efficiency of wastewater.

2. Removal of Harmful Substances

2.1 Bacillus licheniformis:

Bacillus licheniformis can break down toxic and harmful substances in wastewater, such as complexes of heavy metal ions. Through its metabolic activities, it changes the chemical structure of harmful substances, causing them to precipitate or convert into less toxic or non-toxic forms. When treating industrial wastewater contaminated with heavy metals, adding an appropriate amount of Bacillus licheniformis formulation can help reduce the toxicity of heavy metals in the wastewater and improve its treatability.

2.2 Bacillus coagulans:

Although Bacillus coagulans is primarily used in animal intestinal-related fields, it also has potential in wastewater treatment. Under specific conditions, it can participate in the decomposition metabolism of some organic matter in wastewater, working together with other microorganisms to promote wastewater purification.

二. Waste Management

1. Odor Control

1.1 EM Composite Bacteria:

EM composite bacteria are effective in controlling odors from waste. In waste transfer stations, landfills, and other waste disposal sites, regular spraying of EM composite bacterial solution on the surface of waste can rapidly decompose odor-causing organic compounds such as sulfur-containing compounds and ammonia, effectively eliminating odors and improving the air quality of surrounding areas.

1.2 Bacillus subtilis:

Bacillus subtilis can also be used for odor control by breaking down organic components in waste, reducing the odors produced by the decay of organic matter. Adding Bacillus subtilis formulations at appropriate times during waste management can reduce the intensity of odors at waste disposal sites.

2. Waste Decomposition and Resource Recovery

2.1 Bacillus licheniformis:

Bacillus licheniformis can participate in the decomposition of biodegradable organic matter in waste. In some organic waste processing plants, introducing an appropriate amount of Bacillus licheniformis can accelerate the decomposition of organic waste such as kitchen waste, converting it more quickly into resources like organic fertilizers.

2.2 EM Composite Bacteria:

In addition to odor control, EM composite bacteria also play a role in waste decomposition. By promoting the breakdown of organic matter in waste, they help increase the recyclability and utilization rate of waste, such as converting organic waste into compost for resource recycling.

三. Soil Remediation

1. Improvement of Soil Structure

1.1 Bacillus subtilis:

Bacillus subtilis can secrete extracellular polysaccharides and other substances in soil, which bind soil particles together, improving soil aggregation and aeration. This makes the soil structure more porous and loose, benefiting plant root growth and the absorption of water and nutrients. In compacted or hardened agricultural soils or industrially polluted sites, spreading Bacillus subtilis formulations can improve the physical properties of the soil.

1.2 EM Composite Bacteria:

EM composite bacteria can promote the rapid release of available nutrients in soil, improving soil structure. The multiple microorganisms contained in EM composite bacteria work synergistically in the soil, not only breaking down organic residues and increasing soil fertility but also affecting the physical and chemical properties of the soil through their metabolic activities, making the soil more suitable for plant growth.

2. Removal of Soil Contaminants

2.1 Bacillus licheniformis:

Bacillus licheniformis can break down toxic and harmful substances in soil, such as pesticide residues and petroleum pollutants. In soil remediation projects, adding an appropriate amount of Bacillus licheniformis formulations can decompose pollutants into harmless substances through their metabolic activities, gradually restoring the ecological functions of the soil.

2.2 EM Composite Bacteria:

EM composite bacteria also show promise in removing soil contaminants. By promoting the activity of microorganisms in the soil, they accelerate the degradation and transformation of pollutants, helping to purify the soil environment and restore good planting conditions.

四. Environmental Monitoring and Evaluation

1. Microbial Indicator Monitoring

1.1 In the implementation of environmental protection projects, various microbial products produced by your company can be used as monitoring indicators. For example, by regularly testing the survival numbers and activity states of Bacillus subtilis, EM composite bacteria, etc., in wastewater treatment systems, the effectiveness of wastewater treatment can be assessed. If the microbial numbers and activity do not meet requirements, it may indicate issues in the treatment process, requiring timely adjustments to the treatment plan.

1.2 In soil remediation projects, the survival and effectiveness of introduced microbial products can also be monitored to evaluate the progress and quality of soil remediation.

2. Comprehensive Evaluation

2.1 Combining traditional environmental monitoring indicators (such as chemical indicators of water quality and physicochemical indicators of soil) with microbial indicators to conduct a comprehensive evaluation of environmental protection projects. This provides a more comprehensive understanding of the project's effectiveness, allowing for timely identification and resolution of issues to ensure that environmental protection projects achieve their expected goals.

By comprehensively utilizing various microbial products from your company and implementing the above environmental protection solutions, we can play an active role in multiple environmental protection fields such as wastewater treatment, waste management, and soil remediation. This will effectively improve environmental quality and achieve sustainable development in the environmental protection industry.
