DTRO membrane technology has a wide range of applications in industrial production, and its technical advantages are mainly reflected in four aspects:
1.The membrane pore size is small, the membrane flow channel is wide, and the membrane flux is large, which can provide efficient wastewater pollutant filtration and wastewater treatment efficiency.
2.The surface of the membrane is smooth, and the deflector plate has a bump design, which has strong anti-pollution ability. When the wastewater flows through the membrane channel and hits the bump of the deflector plate, high-speed turbulence can be formed, and pollutants are not easy to accumulate and cause membrane material failure.
3.The process flow is short, which saves time and shortens the treatment cycle compared with the biochemical comprehensive treatment of wastewater;
4.Flexible installation and disassembly, low maintenance costs, diaphragm and deflector plate can be replaced separately in the event of a failure;
5.It occupies a small area, has low energy consumption and low investment cost.
With the expansion and improvement of China's industrial production scale and production capacity, the people's living conditions have been greatly improved. At the same time, in the process of social construction and development, the generation of various wastewater has a profound impact on the harmony of the relationship between man and nature. The application of DTRO membrane can help alleviate the contradiction between social development and natural ecology, and provide an excellent solution for wastewater treatment.
The following areas of application for DTRO membrane technology are listed:
1.Domestic waste leachate treatment: Domestic waste leachate is an organic wastewater with high organic matter concentration, large changes in water quality and quantity, and unstable pH value. DTRO membrane technology can effectively filter it, and the effluent quality meets the "Pollution Control Standard for Domestic Waste Landfills" (GB16889-2008), and does not require additional chemical reaction to treat pollutants, and the treatment quality is high;
2.Desulfurization wastewater treatment: "neutralization + flocculation + sedimentation + clarification" is a common way for traditional technology to treat desulfurization wastewater. Switching to DTRO membrane technology can solve the problems of high salinity, high turbidity and high hardness in wastewater treatment effluent, and the effluent can be directly reused to realize the optimal utilization of water resources and effectively reduce environmental pollution;
3.Synthetic pharmaceutical wastewater: This type of wastewater has a complex composition of pollutants and is prone to biological toxicity. The DTRO membrane technology can not only filter impurities and particles, but also filter COD, BOD, benzene, phenol, aromatic hydrocarbons, cyanide and ammonia nitrogen in the water, and the treatment effect is better than that of traditional technology.
