First stage Aerobic biological process: aerobic microbiological absorbs the oxygen part in natural air, maintains metabolism, reaches the purpose of oxidation Decomposition. In this elementary reaction, all will be removed for harmful substances such as the ammonia nitrogen in sewage, nitrite, nitrate, thiocyanogens. Aeration pump can also be increased as attachment device according to the needs of practical situation, provide necessary oxygen to device.
Second stage is held concurrently oxygen biological treatment: oxygen biological treatment of holding concurrently is actually according to the biological decomposition mechanism of hydrolysis acidification, by the facultative biological flora cultivated, Organic substance and the chromophoric group of the difficult degradation in sewage is decomposed, is disintegrated, raising biodegradability.
Three phases anaerobic bio-treated: sewage has turned out facultative biological flora at second stage, these organic compound are as electron acceptor, being taken as the biodegradation process of electron donor, Organic substance is converted to the end products based on volatile fatty acid simultaneously.Acidization is dependent on zymogenous bacteria substantial amounts of, diversified and completes, in antibacterial, major part is obligate anaerobe and facultative anaerobe, amphimicrobe is when reactor is subject to the impact of oxygen, energy is oxygen depleted rapidly, keep the lower oxidation reduction potential of sewage, safeguard the service condition of methanogen, sewage is carried out deep oxidation degraded.
Four-stage biological micro-electrolysis aoxidizes: biological micro-electrolysis is dependent on the sequestration iron ion on bio-carrier (biological cotton) surface and has high chemically active H, Fe2+ what the souring stage of water body produced nascent state, make the long chain organic compound chain rupture in water body convert to the intermediate of little strand, improve the biodegradability of water body.
Advanced treatment system ensures the stably reaching standard of effluent quality, by the waste water of advanced treating, can be used for plant irrigation, rinse the reuses such as road surface. Electrolysis unit used in this application is purchased from market.
The cardinal principle of the high-energy physics oxidation reactor in pretreatment system and advanced treatment system is: high energy particle direct oxidation technology is on electrochemical basis, metal electrode is modified, under external electric field, in anodic coating, electronics starts to migrate, and drives particle, ion motion. Charged particle is gathered, and under induction excites, aqueous solution is bombarded, sorts by bunchy, it is thus achieved that the oxidative free radical thing of newborn situation, chloride ion is excited into hypochlorous acid. Pollutant oxidation in water body is decomposed by these oxidizing species. Under extra electric field state, electronics is to cathodic migration, and negative electrode release hydrogen atom is to the pollutant oxidation reduction reaction in water body.
Preferably, described intelligent sewage treatment unit also includes for storing sewage and the regulating reservoir of preliminary treatment sewage, and the outlet of described regulating reservoir connects with the entrance of described pretreatment system.
Sewage can be stored by regulating reservoir, and carries out preliminary process, for instance microbial decomposition, sedimentation etc. so that the handlability of the water body entering follow up device improves. Water pump it is additionally provided with, in order to by sewage transport to pretreatment system in regulating reservoir.

When using said apparatus to process sewage, substantially process is as described below:
First being sent in said apparatus by sewage sewage pump, sewage is carried out pretreatment by the high-energy physics oxidation reactor in pretreatment system 1;
Sewage flows in device, and the activated sludge in sewage is separated by the biomembrane of carrier material cladding with larger molecular organics. what in high-performance bio contact oxidation reactor 2, addition prepared in advance contains the aerobic microbiological (antibacterial that sewage disposal is conventional, actinomycetes, fungus, protozoacide and micro-metazoa etc.) and facultative biological flora, obligate anaerobe (the mainly escherichia coli of enterobacteriaceae, aerobacteria, Bacillus proteus etc.) bacterium solution (bacterium solution is mainly through white sugar, the allotment such as bio-feritlizer and additive forms), rely on the flowing of sewage, various microorganism adsorptions are on the surface of carrier material, aerobic microbiological maintains metabolism, reach the purpose of oxidation Decomposition. in this elementary reaction, all will be removed for harmful substances such as the ammonia nitrogen in sewage, nitrite, nitrate, thiocyanogens,
Organic substance and the chromophoric group of the difficult degradation in sewage are decomposed, disintegrate by the facultative biological flora of second stage, improve biodegradability.
Sewage has turned out facultative biological flora at second stage, and these organic compound, as electron acceptor, are taken as the biodegradation process of electron donor simultaneously, and Organic substance is converted to the end products based on volatile fatty acid. Acidization is dependent on zymogenous bacteria substantial amounts of, diversified and completes, in antibacterial, major part is obligate anaerobe and facultative anaerobe, amphimicrobe is when reactor is subject to the impact of oxygen, energy is oxygen depleted rapidly, keep the lower oxidation reduction potential of sewage, safeguard the service condition of methanogen, sewage is carried out deep oxidation degraded.
The biological micro-electrolysis of four-stage be dependent on the sequestration iron ion on biological carrier materials surface water body souring stage produce nascent state there is high chemically active H, Fe2+, make the long chain organic compound chain rupture in water body convert to the intermediate of little strand, improve the biodegradability of water body. In whole course of reaction, electrochemistry is participating in synergism all the time.
Activated sludge and carrier material is retained in settling tank;
Sewage processes with electrolysis system in advanced treatment system;
Whether the water after finally detection process meets discharging standards, discharge after up to standard.
Embodiment 2
On the basis of embodiment 1, in other preferred embodiment, intelligent sewage treatment unit also includes regulating reservoir (not shown in figure 1). Sludge recirculation system 5 connects with regulating reservoir. Sewage can be stored by regulating reservoir, and carries out preliminary process, for instance microbial decomposition, sedimentation etc. so that the handlability of the water body entering follow up device improves.
Compared with existing several sewage water treatment methods, the application has that floor space is little, expense is low, steady operation and other merits, referring specifically to table 1 below.
Table 1 the application is compared with the prior art
By upper table 1 it can be seen that use the intelligent sewage treatment unit that the application provides and the method processing sewage, it is possible to efficiently, the process sewage of low cost.
The intelligent sewage treatment unit that the application provides, its intelligence degree is high, and maintenance is simple, operation cost is low.
