Description
Technical field
The utility model relates to a kind of sequence batch (apparatus for treating sewage and waste disposal plant, belongs to sewage treatment area.
Background technology
Develop growth rapidly along with the industry such as chemical fertilizer, petrochemical complex, the high ammonia-nitrogen wastewater produced therefrom is one of restraining factors becoming industry development also.It is reported, there is red tide up to 77 times in calendar year 2001 China marine site, and ammonia nitrogen is the pollution that one of major reason polluted, particularly high-concentration ammonia nitrogenous wastewater cause.Therefore, cost-effective control high strength ammonia polluted by nitrogen also becomes the important topic of current environmental worker research, obtains the great attention of insider.In waste water, the formation of ammonia nitrogen mainly contains two kinds, a kind of is that ammoniacal liquor form exists the ammonia nitrogen formed, a kind of be inorganic ammonia formed ammonia nitrogen (as, ammonium sulfate, ammonium chloride etc.), the main source of the general upper ammonia nitrogen in waste water of pH more than neutrality is the common effect of inorganic ammonia and ammoniacal liquor, and the ammonia nitrogen main component of pH under the condition of acidity in waste water is inorganic ammonia.
At present, main denitrogenation method has biological process (nitration denitrification), break point chlorination, air lift stripping and ion exchange method etc.Wherein blow-off method is because apparatus and process is simple, treatment effect is stablized, and practicality is stronger.
Blow-off method is used for removing ammonia nitrogen in water, passes in water by gas, and gas-liquid is contacted with each other fully, makes the free ammonia (ammoniacal liquor) dissolved in water through liquid-gas interface, to gas phase transfer, thus reaches the object of removal of ammonia and nitrogen.This method is commonly used air and is made carrier (if make carrier with water vapour, claiming stripping).Ammonia nitrogen in water, greatly mainly with ammonium ion (NH
4+) and free ammonia (NH
3) keep the state of balance and exist.Its balanced relationship is as follows:
Percentage partition ratio between ammonia and ammonium ion can calculate with following formula:
Ka＝Kw/Kb＝(C
NH3·C
H +)/C
NH 4+
PH value affects free ammonia one of percentile principal element in water, and when pH value is greater than 10, the rate of dissociation is more than 80%, and when pH value reaches 11, the impact of the rate of dissociation up to 98% and by temperature is very micro-.
Ammonia aeration generally adopts stripping pond and stripping tower two kind equipment, but stripping pond floor space is large, and easily causes secondary pollution, and therefore stripping often adopts tower equipment.Stripping tower built with the filler of certain altitude, to increase gas-liquid mass transfer area thus to be conducive to ammonia desorb from waste water.Customary filler has Raschig ring, polypropylene Pall ring, polypropylene polyhedron empty ball etc.
Current blow-off method is mainly used for the pre-treatment of dense ammonia nitrogen waste water, when ammonia nitrogen concentration is reduced to a certain degree, its stripping efficiency reduces rapidly, and its major cause is that the reduction of ammonia nitrogen concentration makes the concentration of free ammonia in liquid phase reduce, and resistance to mass transfer is increased.In order to the requirement making ammonia nitrogen meet follow-up further process, just must make stripping equipment continuous service when poor efficiency, thus overall processing efficiency is reduced, running cost significantly raises.Therefore be necessary to carry out technological innovation improvement, improve the removal efficiency of stripping equipment under the ammonia nitrogen waste water of middle lower concentration.
Utility model content
The technical problem that the utility model solves is, improves the removal efficiency of stripping equipment under the ammonia nitrogen waste water of middle lower concentration.
The technical solution of the utility model is, provides a kind of sequence batch (apparatus for treating sewage, comprises water inlet pipe, rising pipe, inlet pipe and escape pipe that tank body and one end are connected with tank body, also comprises the distribution device be arranged in tank body; Described water inlet pipe, escape pipe are located at the top of distribution device with the Link Port of tank body respectively, and rising pipe, inlet pipe are located at the below of distribution device with the Link Port of tank body respectively, and escape pipe is connected air extractor and air feeder respectively with the other end of inlet pipe.
Further, one end of inlet pipe is connected on rising pipe, can reduce the number of the Link Port of tank body and pipeline.
Further, described air extractor is vacuum pump.
Further, described air feeder is Aeration fan.
Further, described distribution device is air distribution plate.
Further, described air distribution plate is micropore air distribution plate.
The utility model provides a kind of waste disposal plant comprising multiple above-mentioned apparatus for treating sewage further, between apparatus for treating sewage by inlet pipe and rising pipe parallel with one another, can the continuous process of solid line sewage.
Further, the escape pipe on each apparatus for treating sewage is connected with same air extractor.
Further, the inlet pipe on each apparatus for treating sewage is connected with same air feeder.
Further, apparatus for treating sewage parallel with one another is two, can meet conventional sewage disposal, the idleness of equipment can not be made too many simultaneously.
The working process of the apparatus for treating sewage that the utility model provides is: first the ammonia nitrogen waste water entering the tank body of retort needs pH value to be adjusted in required scope, then the waste water lifting of specified rate is entered retort tank body, close water inlet pipe, start to start Aeration fan to process, while Air Exposure, open vacuum pump, ullage in retort is made to keep negative pressure, when wastewater treatment completes, close blower fan and vacuum pump, and waste water after opening rising pipe emptying process, then open water inlet pipe, carry out sewage disposal next time.Micropore air distribution plate can increase liquid-gas interface area in sewage, makes free ammonia easily enter gas phase removal.The sewage disposal apparatus that the utility model provides is that multiple apparatus for treating sewage is carried out parallel connection, when wherein a part of apparatus for treating sewage other apparatus for treating sewage when processing is intake, realizes continuous process with this.Adding of other medicaments can also be carried out in retort, as the removal first adopting blow-off method to carry out most ammonia nitrogen, then add chlorination medicament and breakpoint chlorination removal is carried out to a small amount of remaining ammonia nitrogen, thus realize the conbined usage of two kinds for the treatment of processs, while improving treatment effect, reduce facility investment.
The beneficial effects of the utility model are, (1) adopt sequence batch (encapsulation process equipment to process ammonia nitrogen waste water, the fine-grained management of wastewater treatment can be realized, can the parameters of effectively accurate operating device, be conducive to the control of reaction conditions, improve the treatment effect of equipment; (2) equipment adopts seal form, its upper outlet is provided with air extractor-vacuum pump, it is negative pressure that this vacuum pump keeps above the water surface, because the reduction of air pressure effectively can reduce the solubleness of gas in aqueous phase, thus effectively can promote waste water Middle molecule state ammonia and shift in gas phase, effectively can improve the treatment effect of equipment to Low Concentration Ammonia Containing Wastewater; (3) this apparatus for treating sewage structure is simple, easy to operate, and running cost is low and can carry out the process of middle Low Concentration Ammonia Containing Wastewater efficiently, effectively can also change, meet different process operating modes according to processing demands.
