Description

A kind of high-concentration ammonia nitrogen sewage treatment equipment
Technical field
The present invention relates to a kind of sewage disposal device.Especially relate to a kind of high-concentration ammonia nitrogen sewage treatment equipment.
Background technology
CN200410064524.3 discloses a kind of ammonia nitrogen removal tower, comprise tower body and the waste water inlet pipe, treating water outlet pipe, air feed tube and the bleeder that are fixedly mounted on the tower body, the column plate of multilayered structure is installed in tower body, the column plate top is equipped with scum dredger, liquid distribution pipe links to each other with the waste water inlet pipe, be installed in the top of scum dredger, air-distributor is connected with air feed tube, be installed in the below of column plate, the treating water outlet pipe is installed on the bottom (head) of tower body, and bleeder is installed on the cover head of tower body.This ammonia nitrogen removal tower will constantly be discharged in the gas ammonia nitrogen in the waste water through the gas-liquid mass transfer of repeated multiple times, and ammonia nitrogen removes fully in the realization waste water.The treating water outlet pipe for the treatment of water by all column plate layers at the bottom of the tower flows out outside the tower at last, after the gas that passes the column plate layer also passes through scum dredger and liquid distribution pipe, outside the cat head bleeder is discharged tower.This ammonia nitrogen removal tower is insufficient genus batch production because of gas, liquid contact, can not continuous production, and the treatment time is long, efficient is low.
Summary of the invention
The object of the present invention is to provide another kind of high-concentration ammonia nitrogen sewage treatment equipment.To realize that processing efficiency is higher, energy consumption is low; Can also realize resource reutilization.
Technical scheme of the present invention is: comprise knockout drum, knockout drum upper end is provided with and enters charge pump, the knockout drum bottom that waste pipe is communicated with and be provided with wash water valve, it is characterized in that, be provided with and advance 2-6 the gas-liquid mixed spraying gun that waste pipe and blower fan airduct are communicated with in the knockout drum inside top; In knockout drum, be provided with 2-4 piece parallel longitudinal dividing plate; On the gas liquid outlet of knockout drum upper end, eddy flow plate outside the gas-liquid separation is housed, be provided with an ammoniacal liquor holding tank in the knockout drum outside of gas liquid outlet the same side, eddy flow plate in ceramic Pall ring packing layer and gas-liquid mixed are equipped with in ammoniacal liquor holding tank top, the outer eddy flow plate of gas-liquid separation is communicated with successively with the ceramic Pall ring packing layer and the interior eddy flow plate of gas-liquid mixed on ammoniacal liquor holding tank top; The eddy flow plate is provided with the water-jet that is communicated with fresh water pump in the gas-liquid mixed, is provided with the ammonia excretion water valve in ammoniacal liquor holding tank lower end.
The circulation line that described ammonia excretion water valve is communicated with fresh water pump is communicated with.
Working process: the sewage in the gas-liquid mixed spraying gun is with the gas Fast Collision, fully enter knockout drum after contacting; In this process, be dissolved in gas in the sewage from water volatile matter from; Gas-liquid drops to knockout drum with the most of depositing in water in porous barrier collision back again after knockout drum slows down, be deposited to knockout drum behind the eddy flow plate outside the gas-liquid separation that a small amount of fog is equipped with on gas liquid outlet.What settle down discharges from wash water valve; The clear water of the water-jet ejection that ammonia is communicated with fresh water pump in the eddy flow plate in Bauer circular layer and gas-liquid mixed fully absorbs the formation concentrated solution, flows in the ammoniacal liquor holding tank; Expellant gas does not contain ammonia.Ammoniacal liquor can be used as the commercial fertilizer sale after reaching finite concentration.
Advantage of the present invention: (1) processing efficiency of the present invention is higher, energy consumption is low; High-concentration ammonia nitrogenous wastewater once can be removed and put in place; (2) ammoniacal liquor is sold as commercial fertilizer after reaching finite concentration, realizes the utilization again of resource; (3) using ceramic Pall ring filler is the ring-like filler of perforate that a kind of high footpath equates, has improved the vapour-liquid distribution, has made full use of the internal surface of ring, and long service life; Do not change.
