10 Tons and 5 tons  ink waste water treatment equipment Has been sent to the customer

During the production and application of water-based ink, due to the cleaning of equipment, a certain amount of water-based ink waste water is generated. The waste water source of water-based ink in the application field is mainly the drainage of printing related equipment that needs to be cleaned, such as the replacement of ink. Water based ink production wastewater is a kind of industrial wastewater with weak alkalinity, high concentration, high chroma and difficult biodegradation. It is difficult to treat wastewater.

Treatment method of aqueous ink wastewater treatment clear equipment

1. Chemical oxidation coagulation process

The components of wastewater mainly include aqueous ink, starch and surfactant. Under the optimal test conditions of adding 15g / L NaCl, 30.2g/l coagulant FCH and adjusting pH to 8.5, the removal rate of CODCr is 94%, and the removal rate of chroma is very high.

2. Ultrafiltration technology

After the wastewater passes through the three groups of ultrafiltration modules, the COD removal rate reaches 92%, the solid content in the concentrated liquid reaches 99g / L (about 10%), and the turbidity of the permeable liquid is in the range of 0.13-0.4ntu. However, the removal rate of COD is closely related to the amount of soluble pollutants, which cannot be removed by ultrafiltration technology.

3. The combined process of coagulation air floatation and contact oxidation adopts the combined process of coagulation air floatation and contact oxidation, which can comprehensively treat the water-based printing ink wastewater, canteen sewage and domestic sewage to achieve good results.
