Abstract

Abstract: This article will study the application of reverse osmosis advanced treatment technology in the secondary processing of wastewater in the dairy processing industry from the perspective of wastewater quality characteristics, and discuss the characteristics, application principles, and experimental design of the technology. This article will further analyze the effects and existing problems of deep treatment of reverse osmosis through experiments. Through a series of tests, we found that the temperature of the inlet water, the pressure of the system operation, the quality of the inlet water, etc., will all have a certain effect on the efficiency of the deep treatment of reverse osmosis and the long-term stable operation of the device. Then, this paper proposes some improvement and optimization measures for these problems. Through the long-term operation test, it is found that the most prone problem in the operation of the reverse osmosis device is the problem of membrane fouling. Based on this, an optimized treatment process based on the dairy processing industry secondary treatment wastewater treatment project is proposed. For one thing, this process can improve the water production rate and the recovery utilization rate of the secondary treatment wastewater. For another, it can reduce membrane pollution, reduce the cost of system operation and maintenance, and increase the service life of the device.
