Temperature-sensitive magnetic nanomaterial-based emulsified petroleum wastewater treatment device

Abstract

A temperature-sensitive magnetic nanomaterial-based emulsified petroleum wastewater treatment device comprises a first sewage tank, a temperature-sensitive magnetic nanomaterial reactor, a second sewage tank, a magnetic filter, a heat exchanger and a water storage tank, wherein a temperature-sensitive magnetic nanomaterial for deoiling from oil-containing wastewater is arranged in the temperature-sensitive magnetic nanomaterial reactor, the first sewage tank, the temperature-sensitive magnetic nanomaterial reactor and the second sewage tank are sequentially connected to form a wastewater treatment system, and the temperature-sensitive magnetic nanomaterial reactor, the magnetic filter, the heat exchanger and the water storage tank are sequentially connected to form a cleaning system for deoiling and recycling the temperature-sensitive magnetic nanomaterial with the surface which adsorbs oil. The device has the advantages of reasonable structure design, flexibility and convenience in operation, effective deoiling of the emulsified petroleum wastewater, recycling of the temperature-sensitive magnetic nanomaterial in the reactor, great reduction of the cost, no secondary pollution, economic property and environmental protection.

Description

technical field [0001] The invention relates to a treatment device for petroleum wastewater, in particular to an emulsified petroleum wastewater treatment device based on temperature-sensitive magnetic nanometer materials. Background technique [0002] Petroleum wastewater not only seriously pollutes the ecological environment, but also threatens the health of the public [Zheng Shaojian, Wang Liangyan, Li Xinjun, et al. Separation and recovery methods and devices for magnetic photocatalysts in wastewater treatment [J]. Guangzhou Institute of Energy Research, Chinese Academy of Sciences, 2005.]. Therefore, the treatment of petroleum wastewater is of great significance to promote the coordinated development of economy, environment and society[Ting Lü, Shuang Zhang, Dongming Qi, Dong Zhang, Hongting Zhao. wastewater [J]. Journal of Alloys and Compounds. 688(2016) 513-520.]. For a long time, the chemical agent method has been one of the most commonly used methods to achieve oil...

AI Technical Summary

Problems solved by technology

However, the above-mentioned separation equipment and systems are not applied to the treatment of emulsified petroleum wastewater, and only use the characteristics of rapid separation by magnetic adsorption, and do not realize the separation and recovery of materials by virtue of the temperature-sensitive characteristics of temperature-sensitive substances, so they are not suitable for temperature-sensitive Treatment of emulsified petroleum wastewater with sensitive magnetic nanomaterials
