Embodiment Construction

[0024] A method for adsorbing and purifying ammonia nitrogen wastewater with a cross-linked polyvinylpyrrolidone support. After pH adjustment (pH value after treatment) is 6.5~8.0, the ammonia nitrogen wastewater is adsorbed and purified through a cross-linked polyvinylpyrrolidone support. The valve enters the system, and the cross-linked polyvinylpyrrolidone carrier adsorption purification system includes a stainless steel pool body 51, a cross-linked polyvinylpyrrolidone carrier cage 52, an electric cage slide rail 53, an electric heating coil 54, and a water inlet valve 55 , Drainage valve 56, support net cage heating zone inlet 57, support body net cage heating zone outlet 58, condensation pipe 59. A circle of electric net cage slide rails 53 is fixed in the middle of the pool body, 10 cross-linked polyvinylpyrrolidone support net cages 52 are installed at equal intervals on the electric net cage slide rails 53, and a support net cage heating zone is provided above the pool...

Abstract

The invention discloses a method for using a crosslinked polyvinylpyrrolidone supporter to absorb and purify ammonia-nitrogen wastewater. The method creatively utilizes the selective adsorbability of crosslinked polyvinylpyrrolidone to ammoniacal nitrogen in water, and a carbanyl group in the molecular structure can be compounded with an amino group to form a hydrogen-bond complex compound. Artificial zeolite containing crosslinked polyvinylpyrrolidone is mixed with domestic wastewater to sufficiently absorb ammoniacal nitrogen in the domestic wastewater, then crosslinked polyvinylpyrrolidone releases the absorbed ammoniacal nitrogen in a heating desorption manner, and the absorbed ammoniacal nitrogen is released in the form of ammonia gas.

Description

technical field [0001] The invention relates to a method for adsorbing and purifying ammonia nitrogen wastewater with a cross-linked polyvinylpyrrolidone carrier, which belongs to the field of wastewater treatment in environmental protection. Background technique [0002] In recent years, with the continuous improvement of the living standards of urban people in our country, the nitrogen content in urban domestic wastewater has risen sharply, and the random discharge of more and more nitrogen-containing wastewater has caused great harm to the environment. Nitrogen is present in wastewater as organic nitrogen, ammoniacal nitrogen (NH 4 + -N), nitrate nitrogen (NO 3 - -N) and nitrite nitrogen (NO 2 - -N) and other forms, and ammonia nitrogen is one of the most important forms. Ammonia nitrogen in domestic wastewater refers to nitrogen in the form of free ammonia and ionized ammonium, which mainly comes from food residues and laundry sewage. There are many pollution sour...
