Abstract

The invention provides an industrial wastewater treatment system based on a low-temperature mass transfer concentration technology. Waste liquid is subjected to low-temperature mass transfer and carrier gas extraction in the device, the mass transfer unit can transfer 80% of moisture in the waste liquid into air under the driving of low-temperature mass transfer power by utilizing the water vaporpartial pressure difference between the surface of a solution and circulating air, and the moisture separation unit separates out condensed water from saturated humid air in an evaporation section ofa heat pump; and water and waste liquid are concentrated and separated, and no waste is discharged except the separated wastewater concentrated solution in the operation process.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to an industrial wastewater treatment system based on low-temperature mass transfer concentration technology. Background technique [0002] At present, industrial production in various fields will produce a large amount of wastewater, such as electroplating wastewater, pesticide wastewater, acid-base wastewater, heavy metal wastewater, and printing and dyeing wastewater. In recent years, with the awakening and improvement of my country's environmental protection awareness, the requirements for the treatment and discharge of industrial wastewater have become increasingly stringent. The "13th Five-Year Plan" puts environmental protection as a work goal, and the "263" special action in Jiangsu Province requires reducing the total coal consumption and reducing the production capacity of backward chemical industries. The issue of industrial wastewater discharge is also one ...
