The invention belongs to the technical field of belongs to the technical field of zero emission, and particularly relates to a zero-emission waste water recovery device. The zero-emission waste water recovery device comprises a waste water box, a water pump, a chromium rinsing water concentration tank, a first adjusting valve, a ceramic purifying device, a second adjusting valve, an exchanger, an ultraviolet sterilizing device, an ion separator, a third adjusting valve, a primary hyperfiltration device, a secondary hyperfiltration device, a recycling water box and a sewage drainage box, wherein the waste water box is connected with the water pump, the water pump is connected with the chromium rinsing water concentration tank, the chromium rinsing water concentration tank is respectively connected with the first adjusting valve and the ceramic purifying device, the ceramic purifying device is connected with the second adjusting valve, the second adjusting valve is connected with the exchanger, the exchanger is connected with the ultraviolet sterilizing device, the ultraviolet sterilizing device is connected with the ion separator, and the ion separator is connected with the third adjusting valve. By adopting the zero-emission waste water recovery device, heavy metal liquid in the waste water reacts with the chromium rinsing water and is precipitated, so that heavy metal in the water can be separated, and the environmental protection effect is good.
Description
technical field [0001] The invention belongs to the technical field of zero discharge, and in particular relates to a zero discharge waste water recovery device. Background technique [0002] At present, electrophoretic spraying technology is more and more widely used, electrophoretic spraying technology has become more and more popular, has gradually replaced conventional surface coating technology, and has become one of the most important coating technology methods in the world today. Electrophoretic spraying technology produces a large amount of wastewater in the production process, usually these wastewater are directly discharged to the sewage treatment station for treatment, but it has the advantages of increased cost of electroplating solution, large water consumption of production line, large amount of sewage treatment, sewage treatment The station occupies a large area, the construction, use and maintenance costs of the sewage station are high, and it is not conduciv...
