An emulsified petroleum wastewater treatment device based on temperature-sensitive magnetic nanomaterials

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 petroleum wastewater treatment device, in particular to an emulsified petroleum wastewater treatment device based on temperature-sensitive magnetic nanomaterials. Background technique [0002] Petroleum wastewater not only seriously pollutes the ecological environment, but also threatens people's health [Zheng Shaojian, Wang Liangyan, Li Xinjun, et al. Separation and recovery method and device of magnetic photocatalyst in wastewater treatment [J]. Guangzhou Institute of Energy, Chinese Academy of Sciences, 2005.]. Therefore, the treatment of petroleum wastewater is of great significance for promoting the coordinated development of economy, environment and society [Ting Lü, Shuang Zhang, Dongming Qi, Dong Zhang, Hongting Zhao. Thermosensitive poly(N-isopropylacrylamide)-grafted magnetic nanoparticles for efficient treatment of emulsified oily wastewater [J]. Journal of Alloys and Compounds. 688 (2016) 513-520.]. For a long ti...

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
