Description
Technical field
This utility model relates to the intensified denitrification and dephosphorization in environmental project water treatment field, particularly relates to a kind of low energy consumption intensified denitrification and dephosphorization device.
Background technology
Nitrogen, P elements are the essential elements causing body eutrophication, most widely used denitrification dephosphorization technique is anaerobic/anoxic/aerobic process (A/A/O technique), but this technique is provided with mud exteenal reflux, nitrification liquid internal reflux and a large amount of aerations of needs, energy consumption is high, and because the mud demand in age of the polyP bacteria needed for dephosphorization and the nitrifier needed for denitrogenation can not be met simultaneously, it is difficult to realize good Nitrogen/Phosphorus Removal simultaneously.
Considering from low energy consumption, anaerobic technique need not aeration, can save energy consumption.In anaerobic technique, the removable Organic substance of hydrolysis acidification-methane phase；On the one hand dissimilatory iron reduction can improve the sewage disposal system degradation efficiency to hardly degraded organic substance, on the other hand can utilize ferric iron and the ferrous iron of dissolution in reactor, with the phosphor-removing effect that phosphatic precipitation improves sewage disposal system；And under low Organic substance environment, Anammox has the strongest denitrification effect；In anaerobic effluent, dissolved oxygen concentration is zero or the least, not directly discharges, and needs aeration aerating, utilizes BAF for anaerobic effluent oxygenation, and BAF can realize the removal of Organic substance, nitrogen and phosphorus simultaneously simultaneously, further ensures that effluent quality.The combination of above-mentioned several technique, anaerobic stages removes major part Organic substance, few to the little oxygen consumption of load during BAF, can be that the denitrogenation dephosphorizing of low energy consumption provides possible.
Summary of the invention
For intensified denitrification and dephosphorization, reducing energy consumption, this utility model uses a kind of low energy consumption intensified denitrification and dephosphorization device simultaneously, can realize there is efficiency denitrification and dephosphorization under low energy consumption.
This utility model be the technical scheme is that a kind of low energy consumption intensified denitrification and dephosphorization device includes methane phase anaerobic reactor, dissimilatory iron reduction reactor, anaerobic ammonia oxidation reactor and BAF, the outlet of methane phase anaerobic reactor connects the water inlet of dissimilatory iron reduction reactor, the outlet of dissimilatory iron reduction reactor connects the water inlet of anaerobic ammonia oxidation reactor, and the outlet of anaerobic ammonia oxidation reactor connects BAF water inlet.
Described methane phase anaerobic reactor and anaerobic ammonia oxidation reactor are up flow anaerobic sludge blanket reactor, are provided with three phase separator, and have the ferric iron packing layer that 1/1 to three/4ths height for reactor is thick in the middle part of dissimilatory iron reduction reactor.
Wherein methane phase anaerobic reactor is mainly used in organic major part removal and organic nitrogen to the conversion of ammonia nitrogen；Dissimilatory iron reduction reactor is mainly used in chemical dephosphorization, and organics removal, raising oxidation-reduction potential and offer ferrum element, provide suitable condition for Anammox the most further；Anaerobic ammonia oxidation reactor is mainly used in denitrogenation；BAF, for ensureing there are enough dissolved oxygen in water outlet, is further ensured that standard water discharge simultaneously.
It has the beneficial effect that (1) mainly carries out the removal of pollutant, energy efficient under anaerobic environment；(2) for Organic substance, nitrogen and phosphorus, having corresponding reactor to remove targetedly, removal effect is good.

Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings.
nullSewage or waste water containing nitrogen phosphorus，First pass through methane phase anaerobic reactor water inlet 4，Enter methane phase anaerobic reactor 1，Hydrolysis acidification and methane phase through the inside anaerobic sludge，Larger molecular organics is made to become small organic molecule，And major part is removed，Discharge from methane exhaust mouth 2 with the form of methane，Organic nitrogen converts ammoniacal nitrogen simultaneously，Separation through methane phase anaerobic reactor three phase separator 3，Treated sewage or waste water enters dissimilatory iron reduction reactor 6 through dissimilatory iron reduction reactor water inlet 7，The dissimilatory iron reduction bacterium of the inside utilizes the ferric ion that ferric iron filler 8 produces，Carry out dissimilatory iron reduction and remove partial organic substances，Including hardly degraded organic substance，And ferric ion and reduzate ferrous ion，Precipitation can be produced with phosphate influence and carry out chemical dephosphorization，And through to ferric reduction，System oxidation reduction potential has risen，Be conducive to the growth of anaerobic ammonia oxidizing bacteria in follow-up anaerobic ammonia oxidation reactor 10.After sewage dissimilatory iron reduction reactor 6 processes, sewage or waste water water quality changes further, organic concentration reduces and containing bivalence and ferric ion, discharge through dissimilatory iron reduction reactor outlet 9, being entered anaerobic ammonia oxidation reactor 10 by anaerobic ammonia oxidation reactor water inlet 13, now Organic substance in water concentration is low, affects little on the anaerobic ammonia oxidizing bacteria of autotrophic type, and containing bivalence and ferric iron in water, contribute to the growth of anaerobic ammonia oxidizing bacteria.After anaerobic ammonia oxidizing bacteria in anaerobic ammonia oxidation reactor 10 processes, the nitrogen in sewage is removed in a large number, and the nitrogen of generation is discharged through nitrogen air vent 11.Now Organic substance in water, nitrogen and phosphorus concentration are the most up to standard, for guaranteeing effluent quality, consider that anaerobic effluent can not directly discharge simultaneously, need to be through aeration aerating.BAF 16 is added at device end, the water outlet of anaerobic ammonia oxidation reactor 10 is through anaerobic ammonia oxidation reactor outlet, BAF 16 is entered by BAF water inlet 20, because biomembranous existence on biofilm filler 18, under conditions of aeration tube 19 oxygenation, the removal of Organic substance, nitrogen and phosphorus can be carried out simultaneously, improve oxygen in water concentration so that it is qualified discharge simultaneously.During whole service, cooperating of each stage, can reach good organic matter degradation and denitrogenation dephosphorizing.
