Startup is divided into three phases：(1) sludge acclimatization culture period, (2) load improve phase, (3) oepration at full load phase.
First stage sludge acclimatization culture period：It is inoculated with from the sludge through taming, anaerobic sludge point accesses for 5 days
200 cubic metres, the sludge concentration of reaction of inoculation device is 34mg/L, after 40 cubic metres of anaerobic sludges of access daily, adds COD and exists
Anaerobism intermediate pool water outlet after 3000mg/L or so dilution, dosage are 40 cubic metres, by the vaccinizations of 5 days and are added
After diluting waste water, full of whole UASB anaerobic reactors 5.Because the temperature of seed sludge is in 26 ° or so, not up to design and operation
Temperature, therefore, it is necessary to improve temperature of reactor.Small water intermittent water inflow is used daily, is entered 4 hours, is stopped two hours, water rate control
At 2 cubic metres per hour, COD rises for every two days in 3000mg/L or so, volumetric loading control in 0.15kgCOD/ (m3.d), temperature
It is high 1 °.When temperature brings up to 36 °, amount of inlet water keeps constant, and anaerobism intermediate pool water outlet is directly entered without dilution, water inlet
COD is between 16800mg/L-20000mg/L, and continuous operation 2 weeks, later stage COD clearance steps up, and clearance reaches 80%
Left and right.This stage is time-consuming 45 days or so.
Second stage is that load improves the phase：USBA anaerobic reactors 5 start to step up after the operation of first stage
The operating load of USBA anaerobic reactors 5, load is improved by increasing amount of inlet water.Water inlet uses continuum micromeehanics 1-15 days,
Handle water be 2 cubic metres per hour, influent COD between 16800mg/L-20000mg/L, reactor load improve by
1.36kgCOD/ (m3.d) brings up to 1.92kgCOD/ (m3.d), and COD clearance is stable (outstanding in 80% water outlet SS at latter several days
Float)≤47mg/L.During 16-35 days, processing water rises to 3 cubic metres per hour, intakes as anaerobism intermediate pool water outlet,
The load of USBA anaerobic reactors 5 is improved to 2.8kgCOD/ (m3.d), and in ensuing 2 months, amount of inlet water gradually carries
To 7 cubic metres of water of design per hour, reactor load improves to 4.07kgCOD/ (m3.d) later stage water outlet COD clearance height
Stabilization is more than 80%, water outlet SS (suspension)≤40mg/L.
Phase III is the oepration at full load phase：After inflow reaches 7 cubic metres per hour, USBA anaerobic reactors 5 go out
Water 100% flows back, and organic loading reaches 4.5-5.3kgCOD/ (m3.d), and gas production also gradually steps up, factor of created gase 2.7-3.9m3/
(m3.d).Microscopy reactor organisms species branch is reasonable, and generation has granule sludge.After the processing of anaerobic reactor, COD's
Clearance is more than 85%, SS (suspension)≤30mg/L.
During the startup of UASB anaerobic reactors 5, a PH instrument, root are installed on the water inlet pipe of USBA anaerobic reactors 5
According to water situation, an alkali measuring pump is set, controlled by PH instrument, makes reactor pH value stable 7.5 or so, avoids due to entering
Water acidifying makes reactor unbalance.
After the processing of UASB anaerobic reactors 5, make organic pollution such as aliphatic acid, hydro carbons, the phenol in percolate
Class, heterocyclic arene class, multiring aromatic hydrocarbon etc. are all effectively removed, or are decomposed into more degradable small molecule, hence it is evident that are reduced
The toxicity of percolate, heavy metal etc. has also obtained effective removal after a series of flocculation sediments.
The inside of multistep treatment pond 6 is provided with three demarcation strips 6a, three demarcation strip 6a by the sky inside multistep treatment pond 6
Between be separated into four independent regions, four independent regions be respectively aerobic area domain 6b, the first catalytic oxidation region 6c,
Anoxic zones 6d and the second catalytic oxidation region 6e, sewage pass sequentially through aerobic area domain 6b, the first catalytic oxidation region 6c, anoxic
Region 6d and the second catalytic oxidation region 6e, makes sewage pass sequentially through anaerobism, anoxic and aerobic environment, will be organic in sewage
Thing, ammonia nitrogen and phosphorus degraded purification.
Specifically, the aerobic area domain 6b bottoms are equipped with activated sludge layer；Lay in the first catalytic oxidation region 6c bottoms
There is biological membranous layer, and the aerator coordinated with the first catalytic oxidation region 6c, the aeration are provided with outside multistep treatment pond 6
Equipment is provided with some aeration tube 6c1, and some aeration tube 6c1 are placed in inside the first catalytic oxidation region 6c；The anoxic zone

Meter so that sewage is handled by multiple overflow, makes sediment not driven by current.
5. sewage is inputted in USBA anaerobic reactors 5 by water pump 11, sewage carries out anaerobic reaction herein, and macromolecular is had
Machine thing is decomposed into compared with small organic molecule, there is provided the biodegradability of percolate, particularly by being set in USBA anaerobic reactors 5
The Sludge Bed comprising granule sludge or floc sludge carry out anaerobic reaction, connecing in sludge and mud granule occurs for anaerobic reaction
During touching.
6. last, sewage through the 3rd pipeline 12 successively by inside multistep treatment pond 6, flowing into multistep treatment pond 6
Aerobic area domain 6b, the first catalytic oxidation region 6c, anoxic zones 6d and the second catalytic oxidation region 6e；By aerobic area domain 6b receivings
Itself and activated sludge are simultaneously carried out mixed processing by the water of the interior outflow of USBA anaerobic reactors 5, and control dissolved oxygen in certain limit
It is interior；First catalytic oxidation region 6c uses fiber soft-filler as biomembrane contact medium, and controls dissolved oxygen in certain limit
It is interior, and into the first catalytic oxidation region 6c Air Exposure is carried out through some aeration tube 6c1 from aerator,；Anoxic zones 6d
The one layer of hermetically sealable film covered by its top makes sewage be in anaerobic environment, and the simultaneous oxygen bacterium allowed in sewage disappears in metabolic process
Remaining oxygen in water consumption, carry out denitrification denitrogenation；Second catalytic oxidation region 6e equally uses fiber soft-filler as biomembrane
Contact medium, and control dissolved oxygen within the specific limits.Sewage compares greatly in sewage can be removed behind aforementioned four region
The COD of example.
The above described is only a preferred embodiment of the present invention, any limit not is made to the technical scope of the present invention
