Description
Technical field
The utility model relates to medical waste water processing technology field, is specifically related to a kind of medical waste water membrane bioreactor integration apparatus.
Background technology
The main pollutent of current waste water has three classes, the first kind is organic pollutant COD and BOD5, and Equations of The Second Kind is inorganic nutrient salt N, and the 3rd class is ss suspended solid, in sewage, the removal of BOD5 is mainly by absorption and the metabolism of microorganism, then carries out mud-water separation to absorption metabolite and has come.At active sludge and waste water initial stage, there will be very high BOD5 clearance, this is because organic granular in sewage and colloid are attracted to antimicrobial surface, thus caused by being removed, but this adsorption is only worked to suspended substance in sewage and colloid, inoperative to dissolved organic matter.Dissolved organic matter need lean on the metabolism of microorganism, microorganism in microbial film under the condition of aerobic by cell new for organic synthesis a part of in sewage, another part organism is carried out katabolism to obtain the energy needed for cell synthesis, its final product is the stable materials such as CO2 and H2O, and this is also the degradation process of BOD5 in sewage.The aerobic metabolism of microorganism all works to dissolved organic matter in sewage and non-solubility organism, and meta-bolites is harmless stable material, therefore, remaining BOD5 concentration after can making process in sewage reduces, the principle that COD in sewage removes is substantially identical with BOD, namely the clearance of COD depends on the biodegradability of raw waste water, and it is relevant with the composition of sewage.If BOD/COD>0.3, the good biodegradability of sewage, in water outlet, COD value can be controlled in lower level; And if the BOD/COD<0.3 of sewage, the biodegradability of sewage is poor, and after process, remaining COD can be higher in sewage, and sewage is by up to standard for more difficult simple process.For this engineering project, pending sanitary wastewater good biodegradability, only rational technique need be adopted just to make sewage stably reaching standard, in raw waste water, nitrogen exists with NH3-N and organonitrogen form, the nitrogen of these two kinds of forms is combined and is called kjeldahl nitrogen (TKN), and biological denitrificaion is the circulation theory utilizing nature nitrogen, adopts manual method to be controlled.Biological denitrificaion comprises aerobic nitrification and anoxic denitrification two processes.Organonitrogen in sewage, will be hydrolyzed to ammonia nitrogen very soon in biochemical treatment system, and then under the condition of oxygen abundance, ammonium oxidation is become nitrite nitrogen and nitrate nitrogen with nitrobacteria by nitrite bacteria; Under the condition of anoxic, and when having additional carbon to provide energy, by denitrifying bacteria effect, nitrate nitrogen and nitrite nitrogen are reduced into nitrogen effusion.The factor affecting its nitric efficiency is temperature, dissolved oxygen, pH and denitrifying carbon source, in biological denitrification system, nitrifier rate of growth is slower, denitrification then needs to carry out under anoxic conditions, and will when there being abundant carbon source to provide energy, denitrification just can be impelled to carry out smoothly, the technique of process hospital wastewater is more, through nearest vicennial practice principle, some unaccommodated treatment process are eliminated, the more technical process of current domestic employing mainly contains contact oxidation method, SBR method, A-O method, A2-O method, oxidation ditch etc., owner requires waste water stably reaching standard after treatment, easy and simple to handle, working cost is low, the one of SBR activated sludge process owned by France, SBR method has periodical operation, the feature that single pond is run, motion time is water inlet, reaction, precipitation, water outlet, standby 5 basic steps.Owing to being intermittent operation, often convert electrical equipment control, often need active sludge state in adjustment pond, happen occasionally sludge bulking phenomenon.Need higher draining elevation simultaneously, operational administrative is also more complicated, go out water-band mud and still will add subsequent disposal facility, the situation that little this project of adaptation water yield is less, biological contact oxidation process is a kind of form of biological membrane processing method, show through practical experience, it has good removal effect, easy and simple to handle, stable, the advantage that do not produce sludge bulking to organism (BOD).Because denitrogenation is that dephosphorization is realized by spoil disposal, and single catalytic oxidation does not possess these functions by the mixed-liquor return anoxic pond containing ammonia nitrogen is reduced to nitrogen, so undesirable to ammonia nitrogen, phosphorus ligands effect.If perfect further in contact oxidation method technique, can environmental requirement be met, adopt the engineering of single contact oxidation method more in the past, in recent years this technique of less employing, but adopt its combination process.
