With the rapid development of modern industry, a large amount of wastewater is discharged into the environment, which has caused serious pollution to the environment. Among them, plasticizer wastewater is a common industrial wastewater, which is mainly used in plastic products, coatings, inks, rubber, textiles, leather and other industries.
Plasticizer as a chemical substance used to improve the processability and softness of plastics, the common phthalate plasticizers (such as bis(2-ethylhexyl) phthalate) and epoxy ester plasticizers (such as epoxy soybean oil), etc., a large number of organic substances and plasticizer components bring potential risks to the environment, long-term accumulation in the environment may have toxic effects on aquatic organisms, and may enter the food chain, and cause harm to human health at the same time, so the treatment of plasticizer wastewater is very important, in order to solve the problem of plasticizer wastewater, plasticizer wastewater demulsifier needs to be used。
The principle of plasticizer wastewater demulsifier treatment wastewater is to change the surface tension in the wastewater by adding demulsifier to reduce the adsorption between milk droplets, so that the milk droplets flocculate and precipitate, so as to achieve the purpose of purifying wastewater, but it should be noted that the treatment process also needs to take into account the dosage of demulsifier, treatment time, pH value of wastewater and equipment technology and other factors, the selection and control of these factors need to be adjusted and optimized according to the specific characteristics of wastewater to obtain the best treatment effect.
The demulsification of plasticizer wastewater has the advantages of simple operation, stable treatment effect, small addition amount and multi-efficacy, which effectively solves the pollution problem of plasticizer wastewater and achieves the purpose of purifying wastewater. With the continuous progress of science and technology, it is believed that in the near future, plasticizer wastewater demulsifier will be better used and make greater contributions to solving the problem of industrial wastewater pollution.
