Embodiment Construction

[0012] In conjunction with accompanying drawing, the concrete process of this method is described as follows:

[0013] Pump the high-concentration ammonia-nitrogen wastewater in the sewage pool into the No. 1 reactor, add quicklime and calcium peroxide as the alkaline compounding agent, stir the reaction fully, send it to the first aeration tower (or pool) for aeration for 1 hour, and pump it into the second aeration tower (or pool) after the first aeration. No. reactor, add alkaline compounding agent sodium hydroxide and sodium perborate, stir well and then send it to the second aeration tower (or pool) for aeration for 1 hour, pump it into No. 3 reactor after second aeration, add aluminum salt or iron salt Flocculants such as polyaluminum sulfate, polyferric sulfate, etc., after fully stirring, send to the micro-exposure tower (or pool) for aeration for 0.5-1 hour, and then send to the settlement tank (or pool) after micro-exposure, add polymer flocculants such as polyacrylam...

Abstract

A method for treating ammonia nitrogen waste water includes the various unit processes of reaction, aeration and separation, in which the described reaction process lies in that the alkaline compound catalysts of quicklime, calcium peroxide, sodium hydroxide and sodium perborate are added to the waste water in sequence, stirred and reacted, then aeration is made, and finally the flocculant is added, the sedimentation and separation can be made under the action of flocculant. The aeration process can use a aeration tower, also can be implemented by using the existent aeration tank. This invention is applicable to treatment of high-concentration ammonia nitrogen waste water below NH3-N 6000 mg / L to reach the national standard for discharge.

Description

1. Technical field [0001] The invention relates to a treatment method for industrial waste water, specifically a treatment method for high-concentration ammonia nitrogen waste water. 2. Background technology [0002] Nitrogen is a nutrient in water bodies. However, when rivers and lakes receive excessive ammonia nitrogen waste water, eutrophication of the water body will be caused. As a result, aquatic plants such as algae grow wildly, and after death, they are decomposed by microorganisms and consume a large amount of oxygen, causing the water body to be severely hypoxic, resulting in aquatic organisms A large number of deaths, decayed organisms and the reproduction of anaerobic microorganisms make the water turbid, foul-smelling, destroy the ecology, and pollute the environment. Such water can neither be used for drinking nor for irrigation, nor is it suitable for industrial application. [0003] Industries such as coking, chemical fertilizer, oil refining, and chemical ...
