A device for recovery of ammonia in wastewater by use of a cross-flow contact-type degassing membrane mainly includes a cross-flow contact-type degassing membrane mechanism and at least two ammonium fluoride water tanks, the ammonium fluoride water tanks are connected together in parallel, inlet ends of the ammonium fluoride water tanks are respectively concatenated in series with inlet valves, then connected together in parallel, and connected with one upper end side wall of the cylinder body of the cross-flow contact-type degassing membrane mechanism; outlet ends of the ammonium fluoride water tanks are respectively connected in series with outlet valves, then connected together in parallel, and connected with one ammonium fluoride water pump, the outlet of the ammonium fluoride water pump is connected with the other lower end side wall of the cylinder body of the cross-flow contact-type degassing membrane mechanism; and the upper end part and the lower end part of the cylinder body of the cross-flow contact-type degassing membrane mechanism are connected in series with an absorption liquid water tank and an absorption liquid water pump which are sequentially connected; the device has relatively low energy consumption, relatively high nitrogen removal efficiency, low run cost, simple operation, easy management, no production of harmful byproducts, no secondary pollution, achievement of recycling of resources, and other characteristics.
Description
technical field [0001] The invention relates to a device for recovering ammonia gas in waste water by using a cross-flow contact degassing membrane, especially a device directly used for recovering ammonia gas in ammonium fluoride solution, which belongs to the field of resource utilization of rare earth and environmental protection technology field. Background technique [0002] With the rise of the domestic electronics manufacturing industry, the government's strict control of rare earth resources and the continuous deterioration of the domestic environment, it is imminent to improve the utilization rate of rare earth resources and reduce the discharge of waste water. Many experts at home and abroad have conducted various researches on the removal of ammonia, such as vacuum degassing method, dilute sulfuric acid absorption degassing method, etc. However, there are still shortcomings in these technologies such as secondary pollution, high cost, and non-recyclable resourc...
