Description
Technical field
The present invention relates to a kind of sewage water treatment method.
Background technology
Water is the source of human life, and existence is originally.With the development of industrial and agricultural production, water environmental problems become more and more tighter
Weight, quality problem has had a strong impact on the normal life of our mankind.Therefore, it is necessary to find effective sewage purification technology with
Realize the sustainable use of water resource.In recent years, people set up many ripe effective sewage water treatment methods, such as domestic big city
The activated sludge process of sewage treatment plant of city.While Activated Sludge Process is applied, AB methods, A/O methods, A2/O methods, CASS methods,
SBR methods, oxidation ditch process, stabilization pond method, land treatment systems method etc. are also applied in the construction of sewage treatment plant.Based on active dirty
The sewage disposal technology advantage of bricklayer's's skill is sewage strong adaptability, and construction cost is relatively low, and has the disadvantage that operation stability is poor, easily
Generation sludge bulking and sludge loss, separating effect are not ideal enough.Activated sludge process mainly uses the biology of microorganism living
Property is made a return journey except the organic matter in sewage, ammonia nitrogen, the pollutant such as phosphorus.It is various different thin in order to reach preferable wastewater treatment efficiency
Flora falls to need to cooperate under different conditions.Such as:Oxidation Decomposition of the heterotrophic bacterium under aerobic condition to organic matter,
Oxidation (nitration reaction) of the autotroph (nitrobacteria) under aerobic condition to ammonia nitrogen, heterotrophic bacterium is under anaerobic
Using organic matter to reduction (anti-nitration reaction) of nitrite/nitrate etc..Generally, it is considered that nitrifying process is in whole ammonia nitrogen
An important process in degradation process, process is slow, and complete difficulty is higher.It is primarily due to nitrobacteria and belongs to autotrophic type
Bacterium, including Nitrosomas and nitric acid Pseudomonas.Two class bacterium are obligate aerobic organism, and final electricity is used as using oxygen in oxidizing process
Sub- acceptor, unique energy source is used as by the use of DIC (being typically carbon dioxide).So the nitrobacteria metabolism time is long, it is raw
Grow very slow, growing environment is harsher, some common nitrous acid strains will averagely take 26 hours and could breed one times, and nitric acid
The cycle of strain reproduction is longer, and averagely to take 60 hours could breed one times.So can not be micro- with heterotroph under the conditions of a lot
Biology gets the mastery in growth competition.Therefore it is often found that in actual sewage treatment plant running, such as A/O techniques are dirty
The nitrification ability of mud gradually weakens with the time limit of operation, is got the mastery mainly due to heterotroph microorganism in growth competition
So that the ratio reduction of nitrobacteria.In view of above-mentioned defect, it would be highly desirable to a kind of sewage water treatment method, make it with more in industry
Value.
