Textile wastewater oil absorption device based on low-temperature separation technology

Abstract

The invention discloses a textile wastewater oil absorption device based on a low-temperature separation technology, belongs to the technical field of textiles. Based on the scheme that a semiconductor chilling plate is started to cool textile wastewater in an oil absorption tank, nitrogen dioxide gas is promoted to be continuously converted into nitrogen tetroxide, and the magnetic insulation effect of the nitrogen dioxide gas on an auxiliary magnet ball is improved, so that the separation oil absorption double balls are separated from the adsorption ball carrying frame. In addition, the adsorption balls can be dragged to move towards oil stains by virtue of the oleophylic characteristic of Gordonia in a Gordonia culture solution, the oil stains are adsorbed by virtue of coke coarse grains, and the inner phase change ball frame can be forced to shrink due to temperature reduction until a deformed film is punctured by a puncture needle, so that the oil stains are adsorbed by virtue ofcoke coarse grains; therefore, water in the textile wastewater reacts with the sodium peroxide powder; on one hand, oxygen can be provided for life activities of the Gordonia culture solution, and onthe other hand, by means of heat released by the reaction and generated sodium hydroxide, dissolution of grease in the wastewater can be accelerated.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a textile wastewater oil absorbing device based on low-temperature detachment technology. Background technique [0002] Textile wastewater is a variety of wastewater produced in the process of spinning and weaving. Textile industrial wastewater can be divided into several categories: printing and dyeing wastewater, chemical fiber textile wastewater, degumming and wool washing wastewater, among which the most polluted is printing and dyeing wastewater. And chemical fiber textile wastewater, the textile printing and dyeing industry is one of the industrial sectors with large water consumption and more wastewater discharge. According to statistics, the amount of wastewater discharged by printing and dyeing enterprises in my country reaches 3 million to 4 million tons every day. Textile industry wastewater generally contains suspended solids , grease, lint, surfactants and various dye...

Problems solved by technology

[0003] The pollutants contained in textile processing wastewater are various and extremely complex. It is impossible to check all pollutants one by one in the analysis and detection of wastewater. Therefore, only a few items that play a major role in water pollution can be analyzed and detected in environmental monitoring. As an indicator of wastewater quality control, the wastewater produced by textile processing contains various pollutants. If the wastewater is discharged directly to rivers, lakes and seas without treatment, it will cause serious pollution to the natural environment, and it will also seriously affect the survival of human beings. the threat of

[0004] At present, because textile wastewater contains a large amount of oil, it is necessary to treat the oil in it, but in the actual treatment process, usually directly add surfactants (such as detergent, soapy water, etc.), and when adding It is easy to make the surfactant excessive, thus causing secondary pollution to the wastewater
