Ink and wash wastewater treatment in printing factories

Introduction to Ink Wastewater Treatment Equipment and Industry

In industry, ink wash wastewater generally comes from printing factories, which generate a large amount of high chromaticity ink wash and ink wastewater during the production process. The main characteristics of this type of wastewater are high concentration, small water volume, and significant changes in water quality and quantity, making it difficult to use conventional treatment methods for treatment. If ordinary biochemical treatment is used, the investment cost is too high, the treatment cost is too high, and the land area is also very large.

Introduction to Ink Wastewater Treatment Process

Based on the characteristics of ink wastewater in printing factories, our company has adopted patented ink specific treatment agents and improved the printing wastewater treatment system. Small footprint, minimal civil construction, and mostly using polyester products. The investment and treatment costs are relatively low, with a water treatment cost of less than 10 yuan per ton.

The ink and wash wastewater treatment process involves quantitatively adding printing plant wastewater treatment agents into the system. After a period of reaction, a "molecular network" is formed, which naturally settles under the action of gravity in the sedimentation tank. The pollutants that are flocculated and precipitated by the "molecular network" are deposited at the conical bottom of the sedimentation tank and discharged at any time. The supernatant is discharged into the sand tank filtration system and then discharged in compliance with standards.

Other effective treatment processes for ink wash wastewater

The use of coagulation sedimentation+UASB+MBR process can also achieve good treatment results. Coagulation precipitation is used for pretreatment to reduce the burden of subsequent processing. There are two types of subsequent treatments: one is multi-stage aerobic biological treatment, and the other is anaerobic aerobic biological treatment, which is a relatively energy-saving and low-cost process.

The electrochemical wastewater treatment process is based on the HE type electrochemical equipment as the core of the wastewater treatment process. On the basis of traditional electrochemical equipment, combined with research and practical application examples of electrochemical equipment at home and abroad, it continuously innovates and improves specialized equipment developed for the characteristics of high COD concentration, diverse types, difficult degradation, and difficult decolorization of wastewater. Traditional processes are difficult to achieve process control and meet emission standards. Process characteristics: The process flow is simple, modular design, and can be combined with existing processes for modification. The effluent is stable, the treatment cost is low, and low requirements for recycled water can be achieved.

Green Hesheng after-sales service

After the production of the equipment is completed, we will transport the equipment to the customer's location according to the contract requirements. At the same time, we will send professional engineers to the engineering site to guide the installation. After the installation is completed, we will debug it until it meets the emission standards.

After passing the acceptance inspection, we will provide a one-year free warranty period for the normal operation of the equipment. Provide free technical service support to users during the warranty period.

3. After the warranty period, if any malfunction occurs, our company is responsible for troubleshooting, being on call, and conducting regular follow-up visits to reassure customers.
