Problems solved by technology
[0003] At present, the treatment methods for high-salinity and high-ammonia-nitrogen wastewater mainly include physical methods, chemical methods, and biological methods. However, due to the high operating costs of physical and chemical methods, unsatisfactory treatment effects, and easy to cause secondary pollution Promote in practical applications; traditional biological methods have great advantages in the treatment of low ammonia nitrogen wastewater, but when the concentration of ammonia nitrogen in the wastewater is too high, it will inhibit the metabolism of microorganisms, thus making the microorganisms lose their degradation ability

The invention provides a treatment device of high salinity and high ammonia-nitrogen organic wastewater, and relates to field of waste water treatment. The treatment device comprises a pretreatment unit, a desalting unit, a pH adjusting device, a blowoff device and pH call-back device. The pretreatment unit comprises a cooling device, a separating device and a heatinsg device; the desalting unit comprises a triple effect evaporator and a centrifugal machine. The pH adjusting device receives value of adjusting mixing fluid through receiving the alkali liquor; the blowoff device is connected with the adjusting device, and comprises a blowoff tower, a partial nitrification unit and a denitrification unit; the pH call-back device is connected to an outlet of the blowoff device, and used for centralizing the waste water after treatment. The treatment device of high salinity and high ammonia-nitrogen organic wastewater can freeze, separate and melt the waste water through the pretreatment unit firstly, the waste water with higher salinity enters a saline desalting unit, thus the desalting efficiency is improved; moreover, the treatment device is simple in structure and low in cost.
Description
technical field [0001] The invention relates to the field of wastewater treatment, in particular to a treatment device for organic wastewater with high salinity and high ammonia nitrogen. Background technique [0002] At present, industrial wastewater has a large amount of discharge, many types of pollutants, high ammonia nitrogen, and high salinity, which is a wastewater that is difficult to treat. In order to protect the living environment of human beings, industry insiders have been making unremitting efforts in industrial wastewater treatment. Although the traditional chemical treatment, biochemical treatment, and physicochemical treatment methods have been continuously improved, the treatment of industrial wastewater with high ammonia nitrogen and high salinity is still a difficult problem to be overcome. [0003] At present, the treatment methods for high salinity and high ammonia nitrogen wastewater mainly include physical methods, chemical methods and biological met...
