Problems solved by technology
[0004] In the prior art, most of the methods and equipment for industrial wastewater treatment by membrane distillation need to be heated by an external heating device, which requires additional energy consumption and high energy consumption. In addition, during the treatment process, the wastewater is in direct contact with the membrane, causing membrane fouling problems. Severe, membrane fouling will not only reduce the flux, but also cause the membrane to wet and deteriorate, shortening the service life of the membrane

The invention discloses an industrial wastewater treatment device and method based on a membrane distillation technology. The invention belongs to the technical field of industrial wastewater treatment. The industrial wastewater treatment device based on the membrane distillation technology comprises a heat preservation water tank, two symmetrically-arranged supporting frames and a supporting base. A treatment kettle is fixedly mounted at the top of the supporting base; a microporous membrane is fixedly mounted in the treatment kettle; the microporous membrane divides the interior of the treatment kettle into a hot air area and a condensation area, a condenser is fixedly mounted on the inner wall of one side of the condensation area, a drainage pipe communicates with the outer wall of oneside of the condensation area, a bearing is fixedly mounted at the top end of each supporting frame, and connecting shafts are fixedly connected to the two ends of the heat preservation water tank androtationally connected with the bearings. According to the invention, wastewater can be heated by solar energy without an external heating device, energy is saved, the cost is reduced, and the wastewater is not in direct contact with a membrane in the treatment process, so that the pollution to the membrane is reduced, and the service life of the membrane is prolonged.
Description
technical field [0001] The invention relates to the field of industrial wastewater treatment, more specifically, to an industrial wastewater treatment device based on membrane distillation technology and a method thereof. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, it is necessary to develop comprehensive utilization, turn harm into benefit, and take corresponding purification measures for disposal according to the pollutant composition and concentration in the wastewater. can be discharged. [0003] Membrane distillatio...
