The method comprises the following steps of: dividing the waste water which is to be treated and contains acid and ammonia into a cold part and a hot part, and respectively introducing the cold part and the hot part into a deacidification tower from the upper part and the middle upper part of the deacidification tower of a stripping type waste water treatment device, wherein acid gas is introduced into an acid recoverer after being stripped from the top of the deacidification tower; collecting kettle liquid waste water from the bottom of the deacidification tower; introducing the kettle liquid waste water into a deamination tower from the middle upper part of the deamination tower so that ammoniac steam is stripped from the top of the deamination tower; meanwhile, collecting kettle liquid from the bottom of the deamination tower. The heat used by a tower kettle reboiler is derived from the ammoniac steam extracted from the deamination tower; the sulfur residue quantity of the treated waste water is lower than 50mg/L, and the total ammonia content is lower than 100mg/L; and the method provided by the invention has the advantages of simple and easily controlled process, mature technology, low processing cost and energy saving and can be widely applied to various occasions for treating the waste water containing acid and ammonia.
Description
Technical field:
The invention belongs to wastewater treatment and utilize technical field, relate to a kind of method of handling acid gas-containing and ammonia waste water, the treatment process of especially a kind of energy-saving double tower stripping type acid gas-containing and ammonia waste water.
Background technology:
Existing in oil refining, in the Coal Chemical Industry production process; Usually can produce a large amount of waste water that contains sour gas (comprising carbonic acid gas, hydrogen sulfide etc.) and ammonia; To the processing of these waste water with utilize again, could get into follow-up treatment unit or reuse after must isolating sour gas and ammonia earlier.The steam stripped method is the main common technology method that removes sour gas and ammonia in the current industrial process; The technical matters such as single tower stripping that single tower stripping, double tower stripping and band side line are generally arranged; Wherein, The double tower stripping can obtain more purified sour gas and ammonia with single tower stripping process of band side line, be to use technical matters more widely at present, and existing these stripping process all is to adopt live steam to make the cat head thermal source; Power consumption is generally handled one ton of waste water and need be consumed steam 190-300 kilogram all than higher; " a kind of double tower stripping is handled the method that contains phenol, ammonia coal chemical industrial waste water " patent that the contriver once declared in 2008 (Chinese patent number be 200810106916.X) technology is improved original technology; A kind of novel more processing acid gas-containing and the technical matters route of ammonia waste water have been proposed; But through nearly 3 years practice and industry operation; It is wayward to find that existing these technologies exist processing condition; Pressure and temperature is higher to be prone to cause shortcomings such as energy waste; So, propose that design is stable with a kind of technological operation of invention, condition is prone to control and energy-conservation double stripping type art breading contains acid and ammonia waste water, can improve the high present situation of cost in present acid gas-containing, the ammonia waste water treatment process technology effectively; Adapt to the demand that present industry energy conservation reduces discharging new standard to satisfy, realize the industrial application of technology better and have good antifouling benefit.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art exists; Seeking to design provides a kind of energy-saving double tower stripping type to handle the method for acid gas-containing and ammonia waste water; This method adopts maturing appts of the prior art; Realize effective control of energy saving temperature and pressure condition, can remove to optimizing sour gas and ammonia, enable the loss-rate prior art processes and reduce significantly.
To achieve these goals; Process step of the present invention is: make the pending waste water that contains acid and ammonia be divided into hot and cold two portions earlier and get into respectively in the tower from extracting tower top and the middle and upper part of stripping type wastewater treatment equipment, regulating the tower top pressure of controlling extracting tower respectively is 0.1～0.4MPa, and tower top temperature is 40～80 ℃; Tower bottom pressure is 0.12～0.42Mpa; Column bottom temperature is 110～155 ℃, sour gas in the pending waste water is come out from extracting tower top stripping after, pass through overhead condensation and separatory again; Make sour gas get into acid withdrawer, sour gas is reprocessed utilize or release then; Simultaneously, pass through pipeline or pump extraction still liquid waste water from the extracting tower bottom; Again the still liquid waste water that the removes sour gas middle and upper part from deammoniation tower is got in the deammoniation tower; The tower top pressure of regulating the control deammoniation tower is 0.4～0.8Mpa; Tower top temperature is 110～160 ℃, and tower bottom pressure is 0.45～0.85Mpa, and column bottom temperature is 130～180 ℃; Make to contain ammonia vapor and come out, at the bottom of deammoniation tower, gather still liquid simultaneously from deamination cat head stripping; Then the still liquid that removes ammonia is carried out subsequent disposal or directly recycling; Make deammoniation tower the cat head extraction contain the tower still reboiler that ammonia vapor gets into depickling, and then get into follow-up multistage fractional condensation device and concentrate and purifies the direct utilization in back; The used heat of its tower still reboiler is all or part of be taken from that the deammoniation tower cat head extracts out contain ammonia steam; The waste water hydrogen sulfide after it is handled and the residual quantity of carbonic acid gas are lower than 50mg/L, and total ammonia is lower than 100mg/L, standard up to specification.
The inventive method is carried out depickling and deamination process in existing stripping type wastewater treatment equipment system, this device is prior art, uses maturely in the treating processes of trade effluent.
The present invention compared with prior art, its treatment process is more simple and easy to control, the equipment configuration technology maturation of use; Processing cost is low; Condition control in the treating processes is simple, saves energy, can be widely used in the various wastewater treatment occasions that contain acid and ammonia more.
