Embodiment Construction
[0019] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.
[0020] see figure 1 , ammonia nitrogen wastewater treatment method of the present invention, comprises the following steps:
[0021] S1, adding an alkaline compound to the ammonia nitrogen wastewater in the pH value adjustment tank to obtain the first mixed solution;
[0022] S2. Sending the first mixed solution into the chloride mixing tank, and adding a chlorine-containing oxidant to obtain the second mixed solution;
[0023] S3, sending the second mixed liquid into the gas chlorine reaction device;
[0024] S4. The air compressor transmits compressed air to the explosion device installed at the bottom of the gas chlorine reaction device through the air duct, and discharges it into the liquid through the gas explosion device, takes away the generated nitrogen, and passes through the gas chlorine reaction devic...

The invention discloses an ammonia-nitrogen wastewater treatment method. The ammonia-nitrogen wastewater treatment method comprises the following steps of: adding an alkali compound to ammonia-nitrogen wastewater in a pH value adjustment pool, thus obtaining a first mixed liquid; feeding the first mixed liquid into a chloride mixing pool, and adding an oxidizing agent containing chlorine, thus obtaining a second mixed liquid; feeding the second mixed liquid into an air chlorine reaction unit; conveying compressed air to an aerating device arranged at the inner bottom of the air chlorine reaction unit by an air compressor through an air conduit, discharging the air into liquid through the aerating device so as to carry away generated nitrogen, and discharging the air through an air bleeder arranged at the top of the air chlorine reaction unit; and feeding wastewater treated by the process into to a next working procedure through a drain hole arranged at the bottom of the air chlorine reaction unit. The ammonia-nitrogen wastewater treatment method disclosed by the invention has the advantages of simple operation, low cost, low energy consumption, stable effect and the like.
Description
technical field [0001] The invention relates to the field of ammonia nitrogen wastewater treatment, in particular to a method for treating ammonia nitrogen wastewater. Background technique [0002] Ammonia nitrogen wastewater mainly comes from wastewater discharged from industries such as iron and steel, petrochemical, coking, and glass manufacturing, as well as sewage discharged in daily life, animal excrement, garbage permeate, and wastewater from agricultural production. At present, the technologies for treating ammonia nitrogen wastewater mainly include ammonia stripping method, ion exchange method, breakpoint chlorination method, magnesium ammonium phosphate precipitation method and biological method, but the above-mentioned methods all have the following deficiencies: [0003] The air stripping method is to first adjust the wastewater to alkaline, so that the NH in it 4 + The ions are converted into ammonia molecules, and then the ammonia is removed by stripping; due...
