The present invention has four big technological cores:
(1), coagulant sedimentation dephosphorization is adopted:
Namely coagulant sedimentation dephosphorization adds coagulated agent in phosphorus-containing wastewater, makes the PO in water4 3-Generate difficulty soluble salt, settlement separate from water, reach dephosphorization purpose.
10Ca2++2OH-+6PO4 3-→[Ca10(OH)2(PO4)6]↓PKs≈90
Al3++PO43-→AlPO4↓PKs≈23
Fe3++PO43-→FePO4↓PKs≈21
General calcium method dephosphorization method need to control PH at least above 9, and as PH, heavy carbonate is close to removing completely when about 11, and dephosphorizing rate is up to 90%.
Other Coagulation Method need to control PH7～8, and the removal efficiency of Phos may be up to more than 85%.
(2), efficiently catalyzing and oxidizing:
Catalytic oxidation is compared with traditional chemical oxidization method, has that oxidability is strong, oxidizing process non-selectivity, reacts the advantage such as thorough, the process of hardly degraded organic substance waste water is had great using value.The most outstanding feature of this technology is to react with the Organic substance in waste water with hydroxyl radical free radical (OH) for primary oxidizers, the organic free radical generated in reaction can continue to participate in the chain reaction of hydroxyl radical free radical, or after generating organic peroxide free radical, occur oxidative decomposition until being degraded to end product CO further2And H2O, thus reaching the purpose of exhaustive oxidation decomposing organic matter.Organophosphor in waste water can also obtain Partial Conversion.
This technology, by the collaborative coupling in multiple kinds of energy source, makes system produce rapidly the hydroxyl radical free radical (OH) of a large amount of strong oxidizing property, the catalytic conversion efficiency of difficult degradation organic poison can be greatly improved, and without High Temperature High Pressure, operating cost is relatively low.
(3), hydrolysis acidification technique
It is only controlling to carry out at first stage by anaerobic acidification and two stages of methanation that hydrolysis acidification processes technique, makes a kind of anaerobic treatment process that acid-producing bacteria grows under optimal environmental condition.
The feature of hydrolysis acidification technique: acid-producing bacteria is provided preferably growth and metabolic conditions by its technology controlling and process, utilizes acid-producing that sewage is carried out pretreatment, is not only methane-producing reactor and provides mechanism preferably, additionally it is possible to contact or the noxious substance in reduction water.Phase generation of acid-producing bacteria is significantly shorter than methanogen, and rate of producing acid is also above methane backeria methane phase speed.
The advantage of hydrolysis acidification technique is in that: 1. the industrial wastewater containing noxious substance and hard-degraded substance and mud are had very big advantage；2. its impact resistance is stronger；3. improve kinetics and the stability of reaction；4. may select and grow microbial population faster；5. safeguarding by a relatively simple, operating cost is low.
Hydrolysis acidification workshop section mean sludge concentration is about 5000mg/L.Control the acid-producing bacteria in hydrolysis acidification pool, under preferably growth and metabolic conditions, to utilize acid-producing that waste water is carried out pretreatment, it is possible to cut down or reduce the noxious substance in water, the impact resistance of enhancement process system.After anaerobic processes improve B/C ratio, available carbon source can be provided for follow-up denitrification.Additionally, by aminating reaction processes such as deaminations, organic nitrogen is converted into inorganic ammonia nitrogen, lays a good foundation for follow-up aerobic nitrification denitrogenation.
(4), A/O technique
A/O is the abbreviation of Anoxic/Oxic, outside its superiority is in addition to make organic pollution be degraded, also has very strong denitrification functions, and A/O method is the activated sludge process improved.
A/O technique is cascaded aerobic to leading portion anoxia and back segment, and A section DO is not more than 0.2mg/L, O section DO and controls at 2～4mg/L.Anoxia section heterotrophic bacteria, the suspended contaminant such as the carbohydrate in waste water and dissolved organic matter being hydrolyzed to organic acid, make larger molecular organics be decomposed into small organic molecule, insoluble Organic substance changes into dissolved organic matter.Anoxia section heterotrophic bacteria, the pollutant such as protein, fat carry out ammonification (N in organic chain or the amino in aminoacid) to dissociate ammonia (NH3、NH4+), under sufficient oxygen supply condition, the Nitrification of autotrophic bacteria is by NH3-N(NH4+) it is oxidized to NO3-, by refluxing, control is back to A pond, and under anoxic conditions, the Denitrification of heterotrophic bacteria is by NO3-It is reduced to molecular nitrogen (N2) complete C, N, O circulation in ecology, it is achieved waste water harmless treatment.
A/O main technological features: 1. anoxic pond is front, the organic carbon in waste water is utilized by denitrifying bacterium, can alleviate the organic loading of Aerobic Pond thereafter, and the basicity that anti-nitration reaction produces can compensate and carry out nitrated removal further of arriving, raising effluent quality in Aerobic Pond.3. the clearance of BOD5 is higher up to more than 90～95%, and Nitrogen/Phosphorus Removal is up to more than 80%.
It is simple that A/O method has handling process, convenient operation and management；Effluent quality is good, and reliability of technology is strong；Capital expenditure is economized, the advantages such as operating cost is low.
