Background:
A large petrochemical enterprise generates a large amount of wastewater containing oil, salt, and complex organic compounds during the production process, and direct discharge will have a serious impact on the environment.
Solution:
The enterprise has invested in the construction of an integrated wastewater treatment and reuse system, including pretreatment, biochemical treatment, deep treatment, and advanced membrane treatment technologies such as ultrafiltration and reverse osmosis. Firstly, remove large suspended particles and oil from wastewater through pretreatment; Next, use biochemical treatment to remove most of the organic matter; Subsequently, residual organic matter, salt, and microorganisms were further removed through deep processing and membrane technology. Ultimately, the treated water meets the standards for circulating water and is directly reused in the production system, achieving zero discharge of wastewater.
