Ammonia-nitrogen-stripping secondary spraying tower

Abstract

The invention discloses an ammonia-nitrogen-stripping secondary spraying tower. The ammonia-nitrogen-stripping secondary spraying tower is characterized in that a first filler region, a second filler region and a water collecting region are respectively inside the tower body from top to bottom, wherein a primary spraying water distributor is horizontally arranged above the first filler region; a secondary spraying water distributor is horizontally arranged between a second filler region and the first filler region; the secondary spraying water distributor is connected with a secondary spraying pump by a secondary spraying tube; a water inlet tube of the secondary spraying pump is connected with the bottom of the water collecting region; a draught fan interface is respectively arranged at the periphery of the water collecting region; one side of the bottom of the water collecting region is respectively equipped with a man hole and a blow-down tube; and the tube body of the water outlet tube is inserted inside the water collecting region. By virtue of the setting, the ammonia-nitrogen-stripping secondary spraying tower can carry out secondary spraying onto the ammonia-nitrogen wastewater to realize secondary stripping; and wastewater for the secondary spraying and stripping is directly from the tower body, so that wastewater ammonia-nitrogen stripping is more complete, and an ideal ammonia-nitrogen removing effect is achieved; and meanwhile, pressure of a next wastewater processing process is relieved.

Description

technical field [0001] The invention relates to a spray tower for stripping ammonia nitrogen-containing sewage. Background technique [0002] At present, in the industry, the discharge of ammonia nitrogen sewage is large and comes from a wide range of sources. The discharge of a large amount of ammonia nitrogen sewage into the water body not only causes eutrophication of the water body, causes the water body to be black and smelly, and even has a toxic effect on the population and organisms. Ordinary spray towers have only one spray water distributor, and the spray effect is poor. Part of the ammonia nitrogen sewage cannot be absorbed by the filler, but flows down along the inner wall of the spray tower, resulting in incomplete blow-off of ammonia nitrogen and failure to achieve blow-off. The best effect, and the ammonia nitrogen sewage flows into the downstream sewage treatment process, causing a certain pressure on the downstream sewage treatment process. Contents of the...
