Embodiment:
The object of the utility model patent is the nanometer aeration high-performance bio treatment unit providing a kind of livestock breeding wastewater, effectively can remove the method for pollution substance and pathogenic micro-organism etc. in breeding wastewater.
The nanometer aeration high-performance bio treatment unit of a kind of livestock breeding wastewater that the utility model patent provides, its primary structure comprises:
One-level solid-liquid separation sieve, is made up of 40-80 order stainless steel mesh, and mesh screen is 30-45 ° of oblique angle.Breeding wastewater flows through screen cloth under gravity, and in waste water, bulk and particulate solid particulate matter are trapped within slanted screen on the net, and with gravity landing to collecting tank; Sewage then flows into runoff investigation pond.
The mud staticly settled mud discharging mouth bottom runoff investigation pond is discharged; It is floating except pond that effluent stream after leaving standstill is sieved to micro-nano aeration through secondary solid-liquid separation.Semi-enclosed 45 ° of tilting cylinders that secondary solid-liquid separation sieve is made up of 100-160 order stainless steel mesh.Sewage flows into from the online portion of trommel screen, and flow under the influence of gravity into micro-nano aeration and float except pond, insoluble particulates is trapped on trommel screen net surface, under the stripping effect that action of gravity and the cylinder of oblique-roller rotate, falls in collecting tank.
Sewage, when flowing into micro-nano aeration and floating except pond, instills plant flocculation agent by medicine system.Floating except in pond at aeration, the insoluble substance in sewage assembles agglomerating under the throwing out of plant flocculation agent and at the stirring backwater effect float downward of micro-nano bubble to the water surface, scum silica frost is removed in collecting tank by air supporting slag scraper.
The floating water outlet except pond enters double oxygen reaction tank.Oxygen reaction tank of holding concurrently has the polynary microhabitats such as aerobic/facultative/anaerobism, and for difference in functionality monoid microorganism creates good microenvironment, particulate form pollutent is degraded by microorganisms into pollutent or the CO of solubility
2, the product such as water, water quality is tentatively improved.
The effluent stream nanometer aeration high-performance bio treating pond in a subtle way that water quality is tentatively improved.Micro-nano aeration high-performance bio treating pond inner bottom part is furnished with micro-nano aerated conduit, is uniformly distributed high-performance bio ball carrier in pond.Novel carbon nano-fiber matrix, natural nutrition base and high-effective microorganism composite flora is filled with in high-performance bio ball carrier, under the different aerobic environments that micro-nano aeration provides, the growth enrichment of high-effective microorganism composite flora also forms microbial film, form aerobic, anoxic, anaerobic state from outside to inside successively, under the microorganism synergies such as nitrifier, denitrifying bacteria, polyP bacteria, realize efficient denitrogenation dephosphorizing, the organism in sewage is converted into CO
2and water, nitride converted is nitrogen or cell tissue, and phosphate conversion is cell tissue.
The sewage that water quality is improved further flows into biological purifying tank, the waterplant such as black algae, hornwort, watermifoil, water caltrop, eel grass are planted respectively in pond, and throw in the hydrocoles such as freshwater mussel, spiral shell, loach, carp, nutritive substance remaining in sewage is converted into the biomass of waterplant or hydrocoles, by the measure such as periodical reaping, results, nutritive substance is removed from water body.
Implement illustration for one according to the utility model patent, breeding wastewater various pollutant monitoring index after process of the present invention is all better than current discharging standards.
