A nitrogen removal device for denitration wastewater and ammonia nitrogen wastewater

Abstract

The invention discloses a nitrogen removal device for denitrification wastewater and ammonia nitrogen wastewater, comprising a treatment box, the top of the treatment box is fixedly connected with a fixing frame, and a fast mixing mechanism is arranged in the treatment box, and the fixing frame is provided with The air injection mechanism used in conjunction with the rapid mixing mechanism, the front of the top of the treatment box is connected with a feeding pipe and a medicine feeding pipe in sequence from left to right. The invention sets up a fast mixing mechanism and uses the motor as the driving source to drive the stirring rod to rotate. At this time, with the assistance of the auxiliary shaft, the two sets of mounting plates can be driven synchronously to drive the rotating shaft to rotate, and the stirring rod and the auxiliary shaft are synchronized. Drive the first stirring blade to rotate quickly and mix the solution in the treatment box quickly, so that with the help of the fixed sleeve, the driving plate is driven to pull the fixed tube to continuously reciprocate up and down, and then the second stirring blade is continuously moved up and down and the processing The solution in the box is quickly mixed and stirred for the second time.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and more specifically relates to a nitrogen removal device for denitration wastewater and ammonia nitrogen wastewater. Background technique [0002] When thermal power plants use flue gas technology, there will be a large amount of wastewater. At the same time, the wastewater will contain a lot of ammonia nitrogen and other heavy metal impurities. Users need to treat the wastewater in time to avoid excessive discharge of ammonia nitrogen that will cause irreversible harm to the surrounding waters. . [0003] Most users add phosphate to denitrification wastewater and ammonia nitrogen wastewater to form struvite while quickly removing ammonia nitrogen. However, when mixing wastewater with phosphate, the mixing efficiency is low, and the wastewater cannot be mixed within a certain period of time. Complete mixing reaction with phosphate, too long mixing time will not improve the efficie...

AI Technical Summary

Problems solved by technology

[0003] Most users add phosphate to denitrification wastewater and ammonia nitrogen wastewater to form struvite while quickly removing ammonia nitrogen. However, when mixing wastewater with phosphate, the mixing efficiency is low, and the wastewater cannot be mixed within a certain period of time. Complete mixing reaction with phosphate, too long mixing time will not improve the efficiency of ammonia nitrogen removal, will only greatly increase the consumption speed and cost of energy, and will bring great economic losses to users. Therefore, those skilled in the art provide A nitrogen removal device for denitrification wastewater and ammonia nitrogen wastewater is developed to solve the problems raised in the above-mentioned background technology
