Description
Technical field
The present invention relates to Technologies of Coke Plant Wastewater Treatment field, specifically be a kind of new coking chemical waste water ammonia nitrogen component removing
Equipment.
Background technology
Coking chemical waste water be coking or coal gas in high-temperature retorting, purification and byproduct removal process, generation containing volatilization
The industrial wastewater of the heterocyclic compound such as phenol, polycyclic aromatic hydrocarbon and oxygen, sulphur, nitrogen, is a kind of high COD, high ammonia nitrogen and very intractable one
Plant industrial organic waste water.Its main source has three：One is the waste water produced in the dry distillation of coal and coal gas cooling, is coking chemical waste water
Main source；Two be the waste water produced during gas purification, such as gas end-cooling water and crude benzol separation water；Three be in Jiao
The waste water that the subtractive processes such as oil, crude benzol or other occasions are produced.Due to the complicated component of coking chemical waste water, containing substantial amounts of phenol, cyanogen,
The poisonous and harmful substances such as benzene, ammonia nitrogen, the coking chemical waste water of discharge beyond standards can cause serious pollution to environment.Particularly coking chemical waste water
In ammonia nitrogen can cause serious water pollution.Ammonia-nitrogen content is no more than 25mg/L in national regulation waste discharge.
For many years, the processing method both at home and abroad to ammonia nitrogen waste water has carried out numerous studies and exploitation, constantly seeks to remove ammonia
The new way of nitrogen.So far, nitration denitrification method, blow-off method, ion-exchange, break point chlorination etc. be have developed many
Plant treating method.Although the processing method of ammonia nitrogen waste water a lot, is all existed, capital expenditure is big, operating cost is high, processing
The small shortcoming of amount, ammonia nitrogen removal index is difficult to reach national GB 8978-1996《Integrated wastewater discharge standard》Defined discharge mark
Accurate (primary standard ammonia nitrogen is less than 15mg/L, and secondary standard ammonia nitrogen is less than 25mg/L), for high concentration (being more than 5000mg/L)
Ammonia nitrogen waste water is more a lack of effective way.
At present, removing of the people to ammonia nitrogen in coking chemical waste water is general carries out taking off for ammonia nitrogen in waste water using ammonia nitrogen removal tower
Remove, but often effect is undesirable, a kind of open mandate Publication No. CN2737778, title on such as State Intellectual Property Office website

Enter denitrifier and regulate the coking ammonia nitrogen waste water of pH value and enter from tower top waste water inlet pipe in tower, be distributed through liquid distribution pipe
Afterwards, by demister, drop on column plate, after multiple gas-liquid mass transfer and aerated reaction, last processing water is from bottom of towe
Handle outside water outlet pipe outflow tower；Air is blasted in tower by air blower from incoming air conduit, is distributed through air sparger, is upwardly into
Column plate layer, then after demister and liquid distribution pipe, outside tower top exhaust stack discharge tower.In above process, ammonia nitrogen waste water
Fully chemically reacted and be aerated in tray surfaces, the ammonium salt in waste water is changed into free ammonia, pass through the reverse flow of gas-liquid
Dynamic, air is constantly contacted and abundant gas-liquid mass transfer with waste water in tray surfaces, the ammonia nitrogen in waste water is constantly discharged into gas,
Realize the removing of ammonia nitrogen in waste water.The removal effect of new coking chemical waste water ammonia nitrogen component removing equipment its ammonia nitrogen of the structure compared with
In the case that temperature is relatively low in difference, particularly tower, the dissolubility of ammonia is greatly increased, so as to cause the ammonia in waste water to gasify quilt
Removing is fallen, so as to be unable to reach country to discharge standard as defined in industrial wastewater.

Coking chemical waste water enters alkalescence regulation intracavitary, manually adds alkali lye to alkalescence regulation intracavitary by alkali lye addition mouth and is given up to adjust coking
The alkalescence of water, the pH value that alkalescence is adjusted to the coking chemical waste water of intracavitary is adjusted to 9~11.5；Coking chemical waste water after regulation pH value is passed through again
Water pump, which is passed through in heater, is heated to 50~55 degree, and the ammonia in coking chemical waste water after heating can largely gasify, the ammonia after gasification
Connection is passed through in the housing of stripping device together with coking chemical waste water, the ammonia gasified after heated device heating warp beam in housing
Flow fan is evacuated in gas temporary room；Unvaporized ammonia is now in free state in coking chemical waste water, as coking chemical waste water is passed through together
Equably flowed after liquid distribution trough distribution on filler assembly, the ceramic packing on the support arm of filler assembly has micropore in itself
Structure, so as to increase gas-liquid exchange area；The blower fan of hull outside provides wind to the blowing mouth in inner walls, and blowing mouth blows
The wind gone out flows from bottom to top, promotes the ammonia of free state in coking chemical waste water, so that by the ammonia removal in coking chemical waste water；Due to
Motor drive shaft is rotated, the broken coking chemical waste water fallen from the ceramic packing of every group of support arm of the cross bar in rotating shaft
Water droplet, makes the water droplet of coking chemical waste water formation become more short grained water droplet, is so conducive to the ammonia of free state in coking chemical waste water
Change, therefore the new coking chemical waste water ammonia nitrogen component removing equipment enables the ammonia nitrogen in high density fast eliminating in coking chemical waste water, and it is de-
Except efficiency high.
