Product Introduction：

Composite Carbon Source for Electroplating and Printed Circuit Board Wastewater is a high-efficiency carbon source product specifically designed for treating wastewater from electroplating and printed circuit board (PCB) manufacturing. It is formulated by blending various organic compounds—commonly including glucose, sodium acetate, methanol, ethanol, and others—in specific proportions to meet the carbon requirements of microorganisms during the biological treatment of electroplating and PCB wastewater.

It typically appears as a colorless to light yellow liquid and exhibits excellent water solubility, dissolving rapidly in water to provide an immediately available carbon source for microorganisms in wastewater treatment systems.

During the production of electroplated printed circuit boards (PCBs), large volumes of wastewater containing heavy metals, organic pollutants, and other contaminants are generated. This wastewater requires biological treatment to remove nutrients such as nitrogen and phosphorus. In this biological treatment process, the composite carbon source plays a crucial role by supplying energy and carbon skeletons to denitrifying bacteria and other microorganisms, thereby promoting microbial growth and metabolism and enabling effective purification of the wastewater.

Product Advantages：

高效反硝化：能够快速被微生物利用，为反硝化细菌提供充足的电子供体，显著提高反硝化速率，使废水中的硝酸盐和亚硝酸盐高效转化为氮气，从而有效降低总氮含量，实现对电镀线路板废水的深度脱氮处理。

Strong adaptability: It performs reliably under varying water qualities and treatment process conditions, maintaining consistent treatment efficiency even in low-temperature environments or when facing significant fluctuations in wastewater composition. It is fully compatible with other components present in electroplating and printed circuit board (PCB) wastewater and does not adversely affect downstream treatment processes.

High cost-effectiveness: Compared to single-component carbon sources, the composite carbon source combines the advantages of multiple organic compounds. It achieves the same treatment performance with a lower dosage, resulting in reduced operational costs. Additionally, its transportation and storage costs are lower, as it is typically supplied in liquid form, making it easy to store and handle.

Biologically friendly: Its components are readily biodegradable by microorganisms and do not accumulate harmful substances in the environment, making it ecologically safe. Moreover, it helps promote a balanced and stable microbial community, enhancing the shock resistance and overall resilience of the wastewater treatment system.

Easy to dose: It exhibits excellent fluidity and solubility, allowing for precise and convenient dosing via metering pumps or similar equipment. Its simple operation enables flexible adjustment of the dosage according to the actual requirements of wastewater treatment.

Service Industries：

Electroplating industry: The electroplating production process generates large volumes of nitrogen-containing wastewater. Composite carbon sources can be used in electroplating wastewater treatment systems to effectively remove total nitrogen, ensuring that the treated effluent meets discharge standards and complies with environmental regulations.

Printed Circuit Board (PCB) Manufacturing Industry: PCB production involves various chemical processes, resulting in complex wastewater containing high levels of organic pollutants as well as nitrogen and phosphorus. Composite carbon sources play a critical role in the biological treatment stage of this wastewater, significantly enhancing both the efficiency and effectiveness of the treatment process.

Industrial Park Wastewater Treatment Plants: Many electroplating and printed circuit board (PCB) manufacturing facilities are concentrated in industrial parks, and the centralized wastewater treatment plants in these parks receive mixed effluents from these enterprises. Composite carbon sources can be applied in the denitrification processes of these treatment plants to ensure that the park-wide wastewater meets regulatory discharge standards.

Environmental Engineering Companies: When designing and constructing wastewater treatment systems for electroplating and printed circuit board (PCB) manufacturing facilities, environmental engineering companies often select specialized composite carbon sources tailored for these industries as the supplementary carbon source. This ensures stable operation and optimal performance of the wastewater treatment systems.
