Wastewater Demulsifier Water Treatment for Optical Factory

Wastewater Demulsifier Water Treatment for Optical Factory

The optical industry is one of the key pillars of China's national economy, with optical products widely used in military, aerospace, communications, and medical fields. However, as the optical industry rapidly develops, a large amount of wastewater is generated during production. This wastewater contains organic pollutants such as oils and emulsions. If discharged without treatment, it will cause severe environmental pollution.

As an efficient wastewater treatment additive, demulsifier can effectively remove emulsified oil in wastewater and improve the efficiency of wastewater treatment. The characteristics of optical plant wastewater mainly include the following points:

1. High oil content: in the production process of optical products, a large number of organic solvents such as alkanes and aromatic hydrocarbons are used, resulting in high oil content in sewage.

2. High degree of emulsification: Because the oil is in the form of emulsion in sewage, the degree of emulsification is high, making it difficult to remove the oil through conventional physical methods.

3. Large fluctuation of pH value: In the production process, the pH value fluctuates greatly in optical factories, which brings some difficulties to sewage treatment.

4. High content of toxic and harmful substances: the sewage of optical factory contains some toxic and harmful substances, such as benzene, toluene, etc., which are harmful to human body and environment.

Applications of demulsifier in wastewater of optical factory

In the process of sewage treatment in optical factory, the following processes are adopted:

1.Pretreatment: the optical plant sewage is preliminarily precipitated to remove large suspended particles.

2.Breaking emulsion: add new type of demulsifier to the pretreated sewage for demulsification treatment.

3.Sedimentation: the sewage after breaking emulsion enters the sedimentation tank to precipitate and separate organic pollutants such as oil.

4. Filtration: the clear liquid in the sedimentation tank enters the filter to remove the remaining suspended matter.

5.Outflow: The filtered water meets the discharge standard and can be discharged into the sewer.

Through practical application, the treatment effect of the new demulsifier in optical plant sewage is as follows:

1. High demulsification efficiency: short demulsification time, high demulsification rate, can effectively remove oil and other organic pollutants in sewage.

2.Strong adaptability: it has strong adaptability to the fluctuation of pH value and can maintain good demulsification effect under different conditions;

3.Low cost: Compared with the existing demulsifier, the new demulsifier has low cost and significant economic benefits.

The emulsifier for optical plant wastewater has a good effect of emulsification, which provides a new solution for the treatment of optical plant wastewater and makes greater contribution to the environmental protection of optical industry.
