A kind of sewage disposal system
Technical field
The present invention relates to technical field of sewage.More particularly, to a kind of sewage disposal system.
Background technology
The existing technology of Sewage Biological Treatment is mainly activated sludge process and the big class of biomembrance process two.
The biological flora used in activated sludge process is slowly to cultivate domestication out by the activated sludge of sewage treatment plant, The activated sludge culture of different sewage treatment plant biological flora out is blended in biochemistry pool, biological flora be with The form dispersion of grain mud.The subject matter that this activated sludge process exists is that various biological flora mixes, different biological Between exist and prey on, compete, the existent relationship such as interfere, running easily occurs the problems such as sludge bulking, thus Treatment effect is the best；Additionally in activated sludge process, biology is to depend on granule sludge to be scattered in whole cesspool, and biological is dense Degree is restricted, and the same species of microorganism concentration contained in activated sludge is the highest, when concentration is more than 8000mg/L Can produce sludge bulking, large number of biological can death；Three are, during in activated sludge process, all of microorganism concentrates on a pond, Once sewage brings poisonous and harmful substance into, and the microorganism in whole pond all can be affected, thus it is universal to support shock proof ability More weak.So activated sludge process is easily impacted by the change of water quality and quantity, once system is destroyed, and recovering to get up, it is very long to need Process；And the sewage source of sewage treatment plant is continuous print, condition is not had to stop transport for a long time health preserving；So running in spite of illness Biochemistry pool process after water quality be typically up to less than the one of " urban wastewater treatment firm pollutant emission standard " GB18918-2003 Level emission standard A.So, this kind of method applies in general to municipal sewage and the less strict occasion of water outlet requirement.
Biomembrance process is identical with activated sludge process, and the source of microorganism is also by the activated sludge of sewage treatment plant Cultivation slowly tames out, and different biological floras also mixes, but biological flora is attached on solid dielectric, Solid dielectric is referred to as filtrate or carrier, and usual biological growth forms one layer of biomembrane at filtrate and carrier surface, thus, the method It is referred to as biomembrance process.Biomembrane outwards can be divided into anaerobic layer, aerobic layer, attachment water layer, motion water layer from filtrate.Biomembrance process Principle is, first biomembrane adsorbs attachment water layer Organic substance, the aerobic bacteria of aerobic layer decomposed, enter back into lonely layer and carry out Anaerobic digestion, aging biomembrane then is washed out to grow new biomembrane by flowing water layer, and so forth to reach to purify sewage Purpose.Biomembrane is made up of the aerobic bacteria of highly dense, anaerobe, amphimicrobe, fungus, protozoacide and algae etc. Ecosystem, the most various biologies mix, and there is the existent relationships such as predation, competition each other, can make various Biomass Keep a maintenance level, but form the biomembrane of densification, biological concentration relative activity owing to biology depends on carrier surface Adding for sludge, thus treatment effect improves, impact resistance strengthens.
But the biological flora in biomembrance process remains the activated sludge deriving from Sewage Plant, the biological mixing of all kinds Together, active bio is difficult to manual control, thus motility is poor in terms of operation；Additionally, due to the ratio table of carrier material Area is little, therefore volume of equipment load is limited, and biological concentration is relatively low, and treatment effeciency is poor；3rd, the water that biomembrance process purifies is past Toward containing the bigger biological diaphragm come off so that water outlet clarity reduces.So it applies in general to the dirt that ammonia-nitrogen content is low Large Water Treatment Field closes.
If thus be provided that a kind of can according in different sewage pollutant kind use have flora targetedly, And there is higher shock proof ability, the sewage disposal system of the change being adapted to water quality and quantity has real and important Meaning.
