COD-degrading bacteria, also known as COD-removing microbial agents, are microbial formulations used in wastewater treatment. They consist of nitrifying and denitrifying bacteria, Bacillus species, and activating enzymes, capable of forming biofilms or flocs to break down organic pollutants. These bacteria effectively treat both high- and low-concentration COD wastewater, achieving a removal efficiency of up to 96%. Additionally, they can remove other contaminants such as BOD and ammonia nitrogen, while enhancing sludge settleability. They are suitable for treating effluents from industries such as electroplating and dyeing, with a recommended maximum influent organic concentration of 8,000 mg/L. Optimal environmental conditions—including pH, temperature, and dissolved oxygen—must be maintained during application.
Product Introduction:
COD bacterial strains are a type of microbial preparation specifically designed for wastewater treatment, capable of effectively degrading the Chemical Oxygen Demand (COD) in sewage. They are typically composed of various functional and advantageous bacterial strains that rapidly proliferate to form dominant microbial communities, thereby enhancing the degradation rate of pollutants. For instance, the Gandoo domestic wastewater treatment bacteria is a composite bacterial system consisting of over 50 bacterial species from six genera. It can adapt to different water quality environments and autonomously differentiate and select for highly specific bacterial strains.
Product Advantages:
Highly efficient degradation: COD removal efficiency can reach up to 95%, significantly enhancing the biochemical system's capacity to remove BOD, COD, and TSS. Enables rapid startup of wastewater treatment systems without requiring long-term investment.
Strong adaptability: Capable of tolerating extreme conditions such as high salinity and low temperatures, making it suitable for treating complex wastewater with low biodegradability. Exhibits strong self-differentiation ability, enabling it to selectively enrich specific bacterial strains best suited to the prevailing water quality conditions.
Low production and operational costs: Short cultivation cycle and simple operation make it suitable for large-scale applications. No complex equipment or technical support is required during use.
Environmentally friendly: Contains no harmful substances and causes no environmental pollution. Improves water quality and reduces secondary pollution.
Service Industries:
Municipal domestic wastewater: Treats urban domestic sewage and reduces pollutant concentrations such as COD and BOD.
Industrial wastewater treatment: Suitable for high-strength organic wastewater generated by industries such as food processing, pharmaceuticals, chemicals, papermaking, and textile dyeing.
