Petrochemical industry wastewater treatment
The water intake of the petrochemical industry accounts for more than 5% of the national industrial water intake, and the total wastewater discharge reaches 3.37 billion tons, accounting for 17.8 of the total wastewater discharge in the country. It is a typical large discharge of refractory industrial wastewater.
The amount of wastewater produced in the production process of petrochemical industry is large, the concentration of organic pollutants is high, and the composition is complex, and the pollutants in the water are mostly sulfur, phenols, cyanide, benzene, metal salts and other toxic substances.
At the same time, the petrochemical industry is a large water user, a large amount of water and sewage not only increase the cost of enterprises, but also pose a serious threat to the ecosystem of the surrounding water body. At present, petrochemical wastewater treatment mainly adopts the process of physical and chemical pretreatment, secondary biochemical treatment and tertiary advanced treatment, but they generally have problems such as unstable organic matter removal effect, low treatment efficiency and low sewage reuse rate.
The existing engineering practice shows that the Qingda Guohua flat membrane MBR system has the following advantages in petrochemical wastewater treatment:
(1) Effectively degrade organic pollutants and other nutrients in water.
(2) It has the characteristics of strong impact load resistance, high biological treatment efficiency and small footprint.
(3) For the wastewater with moderate conductivity, the effluent can be directly recycled to the cooling circulating water system after the flat membrane MBR treatment, which plays a very important role in reducing pollutant emissions, improving the reuse rate of sewage and ensuring the safety of the reuse system.
