Description
Technical field
The present invention relates to water-treatment technology field, the while of being specifically related to a kind of at the waste water of organics removal, nitrogen and phosphorus
Reason method.
Background technology
Along with the development rapidly of China's industry, thing followed environmental pollution particularly water pollution is increasingly severe.Change
Work manufacturing enterprise is because of its production technology characteristic, and every day discharges a large amount of waste water, if these waste water directly discharge, water body can be caused rich
Nutrient laden, algal blooms, not only reduce water body ornamental value, and make aquatile hypoxia death.River, lake
The influx of primary pollution source nutrient salts nitrogen and phosphorus is continuously increased, and water source occurs in that contaminated phenomenon from the beginning.Some algae
Proteotoxin also can make people be poisoned through food chain, the serious harm mankind and biological existence.Require denitrogenation dephosphorizing is the tightest
Lattice and the generalization of sewage low-carbon source feature, for most of sewage treatment plants, all suffer from processing nitrogen, phosphorus in water outlet and do not reach
Mark and the problem of upgrading of having to.
In the past, some Large Water Treatment Fields use standard activated sludge method, process waste water.Standard activated sludge method
It is difficult to process when compound variation is bigger, efficiency when removing the nutrient salts nitrogen (N) in organic sewage, waste water and phosphorus (P)
Relatively low.In order to be provided with organic pollutants and nutrient salts nitrogen (N) and the removal efficiency of phosphorus (P), once developed multiple biological
Highly processing method, in the biological treatment of the nutrient salts nitrogen (N) removed in sewage and waste water and phosphorus (P), obtains extensively
The method for treating water of general use includes continuous batch-type method for treating water biology.
To this end, Organic substance, nitrogen and the phosphorus removed in waste water have become problem demanding prompt solution the most simultaneously.

Medium absorption Denitrifying Phosphate Accumulating Organisms, and organic contamination composition granule, the heterotrophic microorganism oxidation of organic compounds in aerobic particle mud
Generate electronics, the medium electronically forming electron stream that microorganism anode chamber produces as oxidoreduction, make electronics along with flowing
Waste water is moved to the second reactor by the first reactor, in the second reactor, carries out aerobic process, in aerobic particle mud
Aerobic phosphorous accumulating bacterium utilizes the further dephosphorization of oxygen, nitrobacteria utilize first reactor provide electronics, carry out simultaneously with nitrification with
Denitrification, thus denitrogenation；
(3) the mixing liquid flowed enters membrane filter system, by waste water and aerobic grain after flowing out from the second reactor
Mud separates, and aerobic particle mud introduces mud storage device through internal circulation pump, again returns to recycle, removing Organic substance,
The waste water of nitrogen and phosphorus carries out subsequent treatment again.
Further, in such scheme, described aerobic particle mud is with anaerobic grain sludge as seed sludge, inoculation
Nitrifier, denitrifying bacterium and dephosphorization bacterial, described nitrifier includes nitrite-oxidizing bacterium, Nitromonas, described dephosphorization bacterial polyP bacteria or
Denitrifying Phosphate Accumulating Organisms, and add carbon source, carry out aerobic domestication, cultivate and obtain aerobic particle mud, start the time short, control difficulty
Little, and the activity of the heterotrophic bacteria of two kinds of ripe aerobic particle muds and nitrifier does not all have obvious difference.
Further, in such scheme, described aerobic process, be by air feeder bottom activated sludge to
Upper injection air.
Further, in such scheme, after the mixing liquid of described flowing flows out from the second reactor, entering film
Before filter plant, carry out precipitation process.
Further, in such scheme, described end sinks in step, and hydraulic detention time is 1.5～3.5h, so that heavy
Form sediment fully, alleviate the pressure of subsequent film filtration step.
Further, in such scheme, described membrane filter system is continuous membrane filter device, and continuous membrane filter device is suitableeer
Close filter sewage discharge water after biochemical treatment.
Further, in such scheme, described sewage sludge storage device is sludge storage pool.
Further, in such scheme, the subsequent treatment of described step (3) is to the waste water after processing with detection device
Detecting, if the content of Organic substance, nitrogen and phosphorus all meets the discharge standard of national regulation, then can discharging, if not meeting country
The discharge standard of regulation, then need to return again to process, so circulate, until meeting the discharge standard of national regulation.
Compared with prior art, beneficial effects of the present invention is embodied in: after waste water and aerobic particle mud mix and blend, with
Certain flow velocity sequentially passes through the first reactor and the second reactor, dissolves also in the first reactor under low DO concentration
Fermented organic, more under anaerobic by Denitrifying Phosphate Accumulating Organisms dephosphorization, heterotrophic microorganism oxidation of organic compounds generates electronics simultaneously,
The medium electronically forming electron stream that microorganism anode chamber produces as oxidoreduction, makes electronics along with the waste water of flowing is by first
Reactor moves to the second reactor, in the second reactor, carries out aerobic process, and the aerobic phosphorous accumulating bacterium in activated sludge utilizes
The further dephosphorization of oxygen, nitrobacteria utilizes the electronics that the first reactor provides, carries out and nitrification and denitrification effect simultaneously, thus
Denitrogenation；This method removes nitrogen, phosphorus and Organic substance in waste water the most simultaneously, and forms a stable circulation, has certain
Economic benefit.
