Daily chemical enterprises: Cosmetics have developed well, how to solve the difficult-to-treat daily chemical wastewater? Case description

Daily chemical products are one of the important products not only in people's daily use but also in the manufacturing industry. There are nearly a thousand kinds of products in classification, including cosmetics, detergents, flavors and fragrances and other products. With the development of the market, the trend of cosmetic products continues to increase, and the number of new or renovated factories is also increasing, but it is difficult for enterprises to avoid such problems in the process of new construction or renovation?

Production line, the picture comes from the Internet

New or Renovated Plant Issues
As we all know, waste water is generated in the production process of daily chemical products, and it is difficult to avoid waste water in the production of cosmetic products. The composition of these daily chemical wastewater is complex, containing a large amount of anionic surfactants, fragrances, emulsifiers, suspended solids, oils and other substances, and some of the pollutants also have a certain impact on biochemical treatment. Therefore, in our 15 years of communication with many daily chemical companies, production wastewater is one of the important factors when daily chemical companies build and renovate factories.

In fact, how do we help daily chemical companies solve the wastewater problem? If you like it, you can like, follow, and favorite.

A cosmetic wastewater treatment renovation project in Foshan
The wastewater volume of a cosmetic company in Foshan is 120m3/d, mainly from production process wastewater, cleaning equipment wastewater (reaction kettles, containers, etc.), storage barrel cleaning wastewater, etc. After the detection of wastewater, it is known that the concentration of wastewater is high, the most prominent is that the concentration of COD is 8000-12000mg/L and the concentration of SS is 4000mg/L.

Wastewater treatment method
According to the characteristics of wastewater and the actual situation of daily chemical enterprises, facilities and equipment such as oil separators, regulating tanks, primary sedimentation tanks, reaction tanks, and sedimentation tanks are used for primary treatment. The secondary treatment is mainly biochemical treatment, which adopts the combination of anaerobic adjustment tank, hydrolysis acidification tank and contact oxidation tank.

Through the above method, the COD concentration of the final settling tank drainage can reach about 50mg/L, which is lower than the concentration of the implementation of the discharge standard, and the sewage treatment facility can operate stably for a long time in the daily chemical enterprise, solving the problem of wastewater treatment.

Other daily chemical companies can also refer to this method. If you have any questions, you can comment below or privately message us.
