Abstract

The invention discloses a cross-linked polyvininylpolyrrolidone supporter adsorption and purification system. The cross-linked polyvininylpolyrrolidone supporter adsorption and purification system comprises a stainless steel tank body, a cross-linked polyvininylpolyrrolidone supporter net cage, an electric net cage slide rail, an electric heating coil, a water inlet valve, a water discharging valve, a supporter net cage heating region inlet, a supporter net cage heating region outlet and a condensation pipe. According to the system, the selective adsorbability of cross-linked polyvininylpolyrrolidone on ammonia nitrogen in water is creatively utilized, and carbonyl in a molecular structure can be compounded with amino acid to form a hydrogen bond complex. Artificial zeolite in the cross-linked polyvininylpolyrrolidone is mixed with domestic wastewater so that the ammonia nitrogen in the water is sufficiently adsorbed; the adsorbed ammonia nitrogen is released by the cross-linked polyvininylpolyrrolidone through a heating and desorption manner and is released in an ammonia gas manner.

Description

technical field [0001] The invention relates to a cross-linked polyvinylpyrrolidone carrier adsorption purification system, which belongs to the field of waste water 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 sources of ammonia nitrogen, the discharge...
