Organic solvent wastewater treatment equipment

working principle

Organic solvent wastewater treatment equipmentFirstly, pretreatment of organic solvent wastewater is carried out to remove suspended impurities and adjust pH value through filtration, neutralization, and other methods, laying the foundation for subsequent treatment. The pre treated wastewater enters the evaporation system, and under specific temperature and vacuum conditions, the difference in boiling points between organic solvents and water is utilized to evaporate the organic solvents and water successively. The steam generated by evaporation enters the condensation system and forms a liquid state after condensation. Organic solvents can be separated and recovered, while water enters the subsequent deep processing unit. The advanced processing unit adopts filtration, adsorption and other technologies to further remove trace organic matter and impurities in water, so that the treated water meets the discharge standards or reuse requirements.

Features of the equipment

Efficient recycling and cost savings: It can efficiently recover organic solvents from wastewater with a recovery rate of over 90%. The recovered solvents have high purity and can be reused in production, significantly reducing the cost of raw material procurement for enterprises.

Distilled water meets discharge standards: multi-stage treatment process is adopted to deeply treat the wastewater, and all indicators of the treated wastewater can meet national discharge standards and can be directly discharged or reused.

Safe and reliable, stable operation: The equipment is equipped with a comprehensive safety protection system, such as explosion-proof devices, temperature and pressure monitoring systems, to ensure safe and reliable treatment of flammable and explosive organic solvent wastewater, and stable operation with low failure rates.

High degree of automation and easy operation: adopting PLC automatic control system, it can achieve fully automatic operation of equipment, including feeding, processing, discharge, solvent recovery and other processes, reducing manual operation and labor intensity.

Strong adaptability and wide application: It can treat various types of organic solvent wastewater, such as alcohols, esters, ketones, etc. It has good treatment effects on wastewater of different concentrations and is suitable for multiple industries.

Energy saving and environmentally friendly, low consumption operation: Adopting efficient heat exchange technology to reduce energy consumption, there is no secondary pollution during operation, which meets the requirements of energy conservation and environmental protection.

Classic Case

Organic solvent wastewater treatment project of a certain chemical enterprise: The enterprise generates 60m ³ of organic solvent wastewater per day, mainly containing ethanol, ethyl acetate and other components with high concentration. After adopting this set of organic solvent wastewater treatment equipment, the organic solvent recovery rate reached 92%, with a daily recovery of about 2.5 tons of organic solvents. After purification, they were reused in production, saving about 1.5 million yuan in raw material costs annually. The treated wastewater meets the discharge standards and has passed the acceptance of the environmental protection department.

Organic wastewater treatment project of a certain printing enterprise: In response to the organic solvent wastewater (COD of about 15000mg/L) containing ink, toluene and other components generated by the factory, after equipment treatment, the COD of the wastewater is reduced to below 100mg/L, meeting the discharge standard. At the same time, organic solvents such as toluene are recovered, reducing waste emissions and raw material consumption by about 800000 yuan annually, solving the environmental problems of the enterprise.
