Technical field
The present invention relates to a kind for the treatment of process of waste water, be specifically related to a kind of method by the anti-high salinity of cultivation, resisting high-concentration Ammonia Nitrification bacterial treatment high salinity high ammonia-nitrogen wastewater, belong to the biological environmental production technical field.
Background technology
Nitrate pollution is one of major reason that causes body eutrophication, and nitrogenous compound is paid attention to widely and studied keeping water body cleaning and prevent that body eutrophication has vital role, having caused in recent years in the control water.The industries such as oil, chemical industry and chemical fertilizer efflux nitrogenous effluent, as leather waste water have that Pollutant levels are high, complicated, characteristics that quantity discharged is large, the qualified discharge difficulty is large; Particularly these waste water have the characteristics (saltiness is greater than 15g/L) of high salt mostly, cause Biodegradability of Wastewater poor, have brought larger difficulty to improvement, cause sizable pressure to environment.
At present the treatment process for high salinity, high ammonia-nitrogen wastewater mainly contains physical method, chemical process, biological method etc., but owing to physics, the chemical method working cost is higher, treatment effect is undesirable, the while very easily causes secondary pollution to be difficult to promote in actual applications; Traditional biological method tool when processing low ammonia nitrogen waste water has great advantage, but when meeting the ammonia nitrogen in waste water excessive concentration, can suppress the metabolism of microorganism, thereby make microorganism lose degradation capability.And because condition restriction, can not carry out desalting treatment in sewage disposal as last, therefore in actual applications, the Selection of Salt-Tolerant high-effective microorganism provides the feasibility of biochemical degradation for the degraded of ammonia nitrogen.
Chinese patent, publication number is the treatment process that CN 101239751 A disclose a kind of high-concentration ammonia nitrogenous wastewater, it adopts intermittent activated sludge process, by improving gradually the method for nutrient solution ammonia nitrogen concentration, enrichment culture nitrobacteria from active sludge, can remove ammonia nitrogen in high density (greater than 500mg/L), but the nitrobacteria of institute's enrichment can't tolerate hypersaline environment, for high salt high ammonia-nitrogen wastewater, such as leather waste water, treatment effect is relatively poor.
Chinese patent, publication number is that CN 101195507 A disclose the method that a kind of ammonia nitrogen waste water is processed, comprise carrier, nitrifier, the aerobic zone that the oxygen concentration gradient that utilizes diffusional resistance to produce in granule interior forms, oxygen-starved area and oxygen-starved area, form the environment that is fit to two processes combinations of nitrification and denitrification in carrier inside, carry out the oxidizing reaction of ammonia owing to the existence of oxygen on the granule sludge top layer, granule interior is because utilize the oxidation products of ammonia to carry out anti-nitration reaction under the anoxia condition, thereby realization single-stage biological nitrogen removal, realize Simultaneous Nitrification and denitrification, reached very high denitrification percent.But the nitrobacteria of institute's enrichment can't tolerate hypersaline environment, and for high salt high ammonia-nitrogen wastewater, such as leather waste water, treatment effect is relatively poor.
Chinese patent, publication number is membrane sepn and the stripping combination treatment method that CN 101987767 A disclose a kind of high ammonia nitrogen and salinity RE waste water, its method steps is: after the Wastewater Pretreatment through disc filter to carrying out preliminary filtration treatment, enter stripping device, behind the ammonia that recovery removes, enter membrane separation unit, wherein produce the water reuse, after concentrated solution is got back to the back stripping device and reclaimed the ammonia remove, again get back to the membrane sepn step.Such technological advantage is: but the good direct reuse of effluent quality, but required cost is too high, and work-ing life is short, the manual operation difficulty.
The 2nd phase of the 26th volume " environmental engineering " April in 2008, it is 800~1000mg/L, ammonia nitrogen 80~100mg/L that the people such as Yu Deshuan, Zhang Yong delivers in " high salinity waste water sludge acclimatization and microbial research " literary composition at influent COD, under the condition of saltiness 17.5g/L, the effectively active sludge of degradation of ammonia nitrogen has been cultivated in domestication.But because COD is high, heterotrophic bacterium forms the competition inhibition to the nitrobacteria of autotrophy, and the nitrobacteria culture cycle is long, and proportion is low in active sludge.Simultaneously, the nitrobacteria of cultivating can't effectively be removed the waste water of high ammonia nitrogen.
The 3rd phase of Volume Four " environmental engineering journal " in March, 2010, Zhao Kaifeng, Wang Shuying etc. deliver that the salt resistance ability to nitrifier is studied in " the NaCl salinity is on the impact of salt tolerant activated sludge settling property and denitrogenation " literary composition, when salinity is in 20 g/L scopes, ammonia nitrogen removal frank still can maintain more than 99%, the salt resistance ability that shows nitrifier is strong, but selected ammonia nitrogen concentration is controlled in the 65 mg/L scopes in its research, for not further research of high-concentration ammonia nitrogenous wastewater.
Leather-making waste water has the characteristics of the high ammonia nitrogen of high salinity, generally adopts physico-chemical pretreatment and aerobic biological treatment combination process, but common nitrifier denitrogenation not only increases investment and land area, and the effluent quality ammonia nitrogen concentration is still very high.Biological reinforcing technology is in order to improve the processing power of Waste Water Treatment, and adds in this system from the dominant bacteria of occurring in nature screening or the composite bacteria by the generation of assortment of genes technology, to remove the method for a certain or a certain class objectionable impurities.For the characteristics of leather waste water high salinity, high-concentration ammonia-nitrogen, Selection of Salt-Tolerant high efficiency nitrification bacterium carries out biological reinforced processing to waste water, and is significant in industrial production.
