Specific embodiment
The invention will be further described below.
Embodiment 1:
A kind of method of lifting sewage processing capacity, comprising the following steps:
S1. the production waste water and sanitary sewage for collecting place (pig farm), first pass through grid canal, remove floating material and larger particles are dirty
Object is contaminated, primary sedimentation tank is then promoted to by submersible sewage pump, wherein larger substance can be torn, be cut off by submersible sewage pump, in primary sedimentation tank
It is separated by solid-liquid separation, is lightened the load for subsequent biochemical processing.
S2. the water outlet after primary sedimentation tank precipitates enters homogeneous conditioning tank, and hot-water circulation pipe is arranged in homogeneous conditioning tank
Road, logical heat transfer make sewage temperature rise 3 DEG C -5 DEG C；Further, heat preservation is covered above homogeneous conditioning tank, expends phase
For same energy on the basis of original sewage temperature, sewage temperature rises 3 DEG C -5 DEG C.Sewage temperature rises in this step process
6℃-10℃。
S3. through homogeneous conditioning tank, treated that water outlet by elevator pump is promoted to UASB reactor, sets in UASB reactor
Hot water circuit pipeline is set, logical heat transfer makes sewage temperature rise 3 DEG C -5 DEG C.
In order to reduce the loss of heat, hot water circuit pipeline is heated by boiler, in the pipeline external that outdoor hot water flows through
Pipe insulation is carried out, expends the identical energy of identical energy charge on the basis of original sewage temperature, sewage temperature rises 3
℃-5℃。
When sewage temperature is promoted, sewage and activated sludge immixture are by larger molecular organics pollutant in sewage
It is degraded to small molecule organic pollutant, while most of organic contamination of degrading, water outlet enters medium sediment pool, is separated by solid-liquid separation.
S4. the supernatant after medium sediment pool precipitates enters and carries out anaerobic-aerobic treatment in the pond A/O, and the pond A/O is divided into anaerobism
Pond, aerobic tank.Anaerobic pond is mainly biological phosphate-eliminating and sets, and sewage is mixed with the sludge of reflux herein, and carries out phosphorus in sludge
Release；The nitrate nitrogen and nitrite nitrogen generated in aerobic tank, which is back in anoxic pond, occurs denitrification, generates nitrogen
Evolution, reaches denitrogenation purpose.
From the pond A/O, water outlet enters first stage precipitation tank, is separated by solid-liquid separation.
S5. the supernatant after first stage precipitation tank precipitates enters progress anaerobic- anoxic- oxic processing, A2/ in the pond A2/O
The pond O is divided into anaerobic pond, anoxic pond, aerobic tank.Anaerobic pond is mainly biological phosphate-eliminating and sets, and sewage is mixed with the sludge of reflux herein
It closes, and carries out the release of phosphorus in sludge；Anoxic pond is substantially carried out anti-nitration reaction, the nitrate nitrogen and nitrous generated in aerobic tank
Hydrochlorate nitrogen, which is back in anoxic pond, occurs denitrification, generates nitrogen evolution, reaches denitrogenation purpose.Meanwhile in aerobic tank, have
Machine pollutant most of microorganism under aerobic condition is degraded, while nitration reaction occurs for ammonia nitrogen.
From the pond A2/O, water outlet enters second-level settling pond, is separated by solid-liquid separation.
S6. the supernatant after second-level settling pond precipitates enters contact-oxidation pool and carries out biochemical treatment, further removes
Organic pollutant in sewage.Contact-oxidation pool water outlet enter in coagulative precipitation tank, further remove sewage in suspended matter and
Particulate matter, supernatant after precipitation enter the filter tank BAF and carry out advanced treating, finally reach Chinese effluent index.
Test example:
On the basis of the method for embodiment 1, winter-spring season is followed by the heat of heating pipe in homogeneous conditioning tank and UASB reactor
Ring, so that sewage temperature averagely rises 10 DEG C, after carrying out peripheral conduits heat preservation on this basis, the temperature-averaging of sewage rises 5
DEG C, on the basis of above, after covering heat preservation above homogeneous conditioning tank, the temperature-averaging of sewage rises 3 DEG C.
As shown in table 1, under the conditions of identical energy consumption, ramp case of the sewage temperature under various heating measures.
As shown in table 2, with the raising of sewage temperature, COD of sewage (chemical requirement mg/L) removal rate is increased.
As shown in table 3, as sewage temperature increases, NH3-N(mg/L) removal rate raising.
Continuous experiment the result shows that: by heating pipe in homogeneous conditioning tank and UASB reactor, (hot water follows low temperature season
Endless tube road) thermal cycle, the heat preservation of peripheral water pipe, above homogeneous conditioning tank after capping measure, under conditions of identical energy consumption, sewage
Temperature-averaging rise 15-18 DEG C, stable operation three months after, COD of sewage removal rate improve 50%, NH3-N removal rate promoted
40%, TP removal rate promote 38%, are obviously improved to wastewater treatment efficiency.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
