Description
Technical field
The present invention relates to a kind of coking waste water treatment method, specifically a kind of high ammonia nitrogen of short distance nitration-anaerobic ammoxidation
Denitrification of Coking Wastewater membrane processing method.
Background technology
Coking wastewater is a kind of typical high-concentration organic industrial waste water difficult to degrade.Coking wastewater main source is coking
In the process, moisture of the coal by high-temperature retorting effusion condensation, has in the moisture of this effusion dissolved with a large amount of, various types of
The considerably complicated remained ammonia of machine object, generation ingredient, is additionally comprised in gas purification process, tar production and crude benzene refining
The waste water of middle generation.Polluter in coking wastewater mainly includes the heterocyclic compound containing sulphur, oxygen, nitrogen etc., polycyclic aromatic hydrocarbon
Class and phenols etc..Phenolic compound is a kind of prototype matter poisonous substance, the carbdism of high concentration can cause violent abdominal pain, vomiting,
The symptoms such as diarrhea and bloody stool, severe person result even in death；Multiring aromatic hydrocarbon is not only difficult to biodegradable removal, but also
Cell carcinogenesis can be easily caused；In addition, a large amount of organic pollutions contained in coking wastewater are drained into water body, water body can be consumed
A large amount of dissolved oxygen in the middle leads to the situations such as the smelly, water quality deterioration of water body, while the noxious material contained in coking wastewater, can be tight
The existence of aquatile in water is threatened again.Therefore, the not qualified discharge of a large amount of coking wastewaters not only causes serious environment dirty
Dye problem, and threaten the health of the mankind.
Traditional coking waste water treatment process mainly includes physical-chemical process and biological treatment.Physical-chemical process, such as
Extraction, absorption method, catalytic wet oxidation technology, Ozonation, photocatalytic oxidation etc., due to catalyst, flocculant etc.
Processing cost is high, and stringent to equipment requirement, and therefore, engineer application is not very extensive.Most important processing work in practice
Skill is biological treatment, such as Biology-iron technology, SBR methods, A/O methods, A/O2Method, A2/ O methods etc., have COD in coking wastewater
Preferable removal effect, but SBR methods are limited due to self-condition, it is impossible to carry out nitration denitrification for a long time, and using AO methods as
Core（Including A/O2Method, A2/ O methods etc.）Biological treatment nitric efficiency influenced by reflux ratio, in actual motion take off
Nitrogen efficiency is not very good, and there are the drawbacks such as floor space is larger, energy consumption is more, and excess sludge production is larger.
At present, how to shorten the conversion process of nitrogen becomes the research hotspot of Treatment of Coking Effluent.Way is converted according to new nitrogen
The new process of diameter research and development mainly includes short-cut nitrification-denitrification（SHARON）, synchronous nitration-denitrification（SND）, anaerobism ammonia
Oxidation（(ANAMMOX）Deng, these new processes or denitrification can be carried out as electron acceptor or being capable of profit using nitrite
Nitrification and denitrification is controlled with aerobic denitrifying bacteria and nitrification bacteria and is realized in a reactor, breaches conventional take off
Nitrogen processing mode.Compared with traditional handicraft, these new processes mostly have the reaction time is short, reactor volume is small, oxygen demand is few,
The advantages such as sludge yield is low have good development prospect.
（1）Short-cut nitrification-denitrification（SHARON）
The basic principle of SHARON techniques is in same reactor, first utilizes nitrite bacteria will under aerobic conditions
Ammoxidation become nitrite, then under anoxic conditions, using organic matter as electron donor, using nitrite as electron acceptor into
Row anti-nitration reaction generates nitrogen.Compared with traditional handicraft, SHARON techniques are with technological process is short, denitrification rates are fast, investment
The advantages such as low with operating cost, but be still difficult to carry out the pH value of oxygen and sludge under conditions of mixed bacterial continuous operation good
Good control.
（2）Synchronous nitration-denitrification（SND）
Traditional biological denitrificaion theory thinks that nitrifying process can only be that autotrophic bacterium is completed, and anti-nitre could occur under anoxia condition
Change process.Simultaneous Nitrification-denitrification is different from traditional nitrification and denitrification process, and main cause is special there is some
Microbiologic population, many aerobic denitrifying bacterias simultaneously be also abnormal nitrifier, can under aerobic condition directly by ammonia nitrogen turn
Gaseous products effusion is turned to, heterotrophic nitrification reaction can also occur under conditions of complete anoxic, so as to fulfill synchronous nitration-anti-
Nitrification.But synchronous nitration-denitrification process often results in the shortcomings of integrated artistic is difficult in maintenance, bacterium colony is complicated uncontrollable.
（3）Anammox（(ANAMMOX）
Anaerobic ammonia oxidation process refers to that under anaerobism or anoxia condition microorganism is directly using ammonia nitrogen as electron donor, with Asia
Nitrate is electron acceptor, by the process of ammonia nitrogen and Nitrite transformation for nitrogen.In Anammox, the oxidation nothing of ammonia nitrogen
The participation of molecular oxygen is needed, the reduction of nitrite is participated in without organic matter.Anaerobic ammonia oxidation process gives up for processing coking
The waste water of the high ammonia nitrogen such as water has good prospect, and due to the partial oxidation for saving nitrite, energy is greatly saved
Source, and how to ensure that the accumulation of nitrite is the key that then that anaerobic ammonia oxidation process effectively carries out.
In conclusion short-cut nitrification-denitrification, synchronous nitration-denitrification and Anammox are handling high ammonia nitrogen
There is significant advantage, development potentiality is huge in terms of coking wastewater.The short-cut nitrification-denitrification and synchronous nitration of single-reactor-
Denitrification process have certain denitrification efficiency, but influence each other between different microorganisms in single-reactor and to DO with
The difference of nutritional need causes nitric efficiency to be difficult to increase substantially.Anaerobic ammonia oxidation process can be with single anaerobism ammonia oxygen
Change bacterium and remove ammonia nitrogen and nitrite simultaneously, but how to stablize and the problem of nitrous acid Yanyuan is urgent need to resolve is provided.It is in addition, single
One short-cut nitrification-denitrification, synchronous nitration-denitrification and anaerobic ammonia oxidation process in coking wastewater COD, phenols with
And other polluters are difficult to realize processing up to standard.
