Quick Details

Given the core characteristics of laboratory wastewater—extremely complex composition, high potential risk, and stringent treatment standards—a professional, safe, and efficient treatment solution is paramount.

Laboratory wastewater originates from a wide range of sources, encompassing various scientific research activities in chemistry, biology, medicine, and other fields. Its water quality exhibits a high degree of complexity and uncertainty. The wastewater may simultaneously contain high concentrations of toxic organic solvents (such as BTEX, halogenated hydrocarbons), various acids and bases, heavy metal ions, pathogenic microorganisms, residual reagents, and experimental intermediates. This mixed wastewater not only features a wide variety of pollutants with significant concentration fluctuations but also includes components that are highly corrosive and biologically toxic. Relying solely on traditional segregated collection and simple physicochemical treatment is not only cumbersome to operate and costly to manage but also often fails to ensure the complete elimination of refractory and toxic substances, posing environmental and safety risks.

Facing this specific challenge, an integrated treatment process centered on highly efficient and broad-spectrum electrochemical oxidation technology demonstrates significant technical advantages. The CQDHX SERIES EO Electrochemical Oxidation Equipment, developed and manufactured by our company, generates highly oxidizing reactive species (such as hydroxyl radicals) through electrochemical action. These species can non-selectively attack and break down the complex organic molecular structures in the wastewater, achieving complete mineralization or harmless transformation. Its core advantage lies in the treatment process requiring no addition of any chemical agents, thereby avoiding the risks of secondary pollution and operational complexity associated with dosing oxidants or reductants. Furthermore, its reaction mechanism ensures that no residual solid waste is generated. For laboratory wastewater with complex compositions that might produce unknown hazardous waste, this greatly simplifies subsequent hazardous waste management and disposal challenges.

Wastewater should first undergo standardized segregated collection and safe temporary storage, followed by entry into a collection and equalization tank for thorough homogenization to buffer extreme fluctuations in water quality and quantity. The pretreatment stage is crucial and typically includes necessary pH neutralization and adjustment to protect downstream equipment, as well as possible units for heavy metal precipitation, oil-water separation, etc., to remove specific pollutants. The pre-treated wastewater then enters the EC Electrochemical Equipment for electrocoagulation treatment. This effectively removes colloidal particles, some organic matter, phosphates, some heavy metals, and color from the water, creating favorable conditions for the advanced oxidation unit.

Subsequently, the wastewater enters the CQDHX SERIES EO Electrochemical Oxidation Equipment. Here, persistent organic pollutants, toxic substances, and microbial metabolic disruptors that remain and are difficult to remove by prior processes are efficiently degraded and destroyed. Leveraging stable electrode performance and an optimized reactor design, our company's equipment ensures the high efficiency and adaptability of the oxidation process. It can effectively handle the variable composition of laboratory wastewater, achieving deep removal of pollutants and effective reduction of toxicity.

Finally, the deeply oxidized effluent can, as needed, proceed to subsequent advanced purification units (such as activated carbon adsorption or membrane filtration).

The CQDHX SERIES EO Electrochemical Oxidation Equipment, with its powerful broad-spectrum oxidation capability, clean operation mode (no chemical addition, no solid waste generation), and excellent resistance to shock loads, provides safe, compliant, and sustainable wastewater treatment assurance for universities, research institutes, testing organizations, and corporate R&D centers. It strongly supports the green and safe conduct of scientific research activities.

For wastewater with special characteristics or unique treatment objectives, our company's engineers provide technical support and solutions.
