Embodiment Construction

[0024] As shown in Figure 1, and referring to Figure 2 and Figure 3, when using the method of the present invention to purify ammonia nitrogen sewage, at first the sewage pH value is adjusted to 10-11 in the waste water tank 10, and through the water pump 9 and the flow meter 2 The sewage is quantitatively sent to the drum 3-1 in the blowing off overweight machine 3, and at the same time, the Roots blower 1 and the flow meter 2 are used to quantitatively deliver air to the blowing off overweight machine; with the input of sewage, the drum 3-1 At the same time, it rotates under the drive of the motor 5, so that the sewage input into it is thrown out to the outside under the action of centrifugal force until it is thrown out to the drum 3 from the through hole 3-1-3 on the circumferential surface of the drum 3-1. -1 in the inner cavity of the super-heavy machine, and finally discharged from the ammonia removal sewage outlet provided on the outer shell of the super-heavy machine; ...

Abstract

The invention discloses a hyper-gravity purification method for ammonia and nitrogen sewage. In the method, a blowing and doff hyper gravity machine is first utilized to carry out a blowing and doff treatment to the sewage. An absorption hyper gravity machine is then utilized to carry out an ammonia removal treatment to the gas concluding ammonia outputted by the blowing and doff hyper gravity machine. The invention also discloses a hyper-gravity machine, which comprises a sealed shell. The top of the shell is provided with a gas inlet and the bottom of the shell is provided with a liquid discharge outlet. A round cylinder shape rotary drum is arranged inside the shell. The surrounding of the drum is densely covered by pylomes. A baffle group is arranged inside the drum. In the central of the drum, a pylome is arranged which is communicated with the gas outlet and liquid inlet on the shell. The hyper gravity blowing and doff hyper technology in the invention is a novel mass-transfer technology which can reduce the tower height, strengthen the mass-transfer and reduces the pressure drop. When hyper gravity blowing and doff hyper technology is used for treating the leachate of the landfill, on one hand, the operation cost can be saved, on the another hand, the recycled ammonium sulfate can be used as fertilizer.

Description

technical field [0001] The invention relates to a method for removing ammonia in ammonia nitrogen sewage and an overweight machine used in the method. Background technique [0002] Domestic garbage leachate is special sewage produced during the landfill process, and its ammonia nitrogen concentration is as high as several thousand milligrams per liter. Moreover, as the age of the landfill increases, the ammonia content in the landfill leachate will gradually increase. These high-concentration ammonia-containing wastewater will cause many hazards. [0003] (1) Cause eutrophication of water body. Since ammonia nitrogen is the main nutrient substance of plants and microorganisms, the increase of ammonia nitrogen content in the water body will cause eutrophication of the water body and promote the reproduction of algae in the water. A large reduction of oxygen will deteriorate the water quality, and fish and other aquatic organisms will die due to lack of oxygen, making the wa...
