Description
Technical field
The present invention relates to technical field of sewage, more particularly to a kind of culturing wastewater processing system and method.
Background technology
The handling process to breeding wastewater is mainly used at A/O methods, i.e. anoxic/aerobic treatment method, the sewage at present
Science and engineering skill can not only remove BOD5, CODcr in sewage, and can effectively remove the nitrogen compound in sewage.Such as at A sections
For pond, also known as anoxic pond or hydrolytic tank, the angle of the mechanism of hydrolysis chemically, most compounds are under certain condition to the greatest extent
Hydrolysis can all be occurred by being contacted with water, and hydrolysis can make covalent bond change and be broken, i.e., compound is in molecular structure
Changed with form.Biological hydrolysis is to lean on the catalytic action of biology enzyme and accelerate reaction, urging under the conditions of having enzyme
Change reaction speed than without being higher by 108-1011 times under the conditions of enzyme.Biological hydrolysis just refers to the organic molecule of complexity through adding water
Under anoxia condition, because the participation of hydrolase is broken down into the reaction of simple compound, biological hydrolysis reaction actually includes
Two processes of hydrolysis and acidifying, acidifying can make organic matter degradation be organic acid.
Other A/O techniques also have good denitrification functions.Sewage enters back into O sections of ponds after A sections of ponds are entered, and sewage is aerobic
Section, organic matter (BOD5) is converted into nitre state ammonia by aerobic microbiological oxidation Decomposition, organic nitrogen by ammoniation and nitrification,
Nitre state ammonia enters anoxic section by sludge reflux, when sewage is through anoxic section, the denitrifying bacterium in activated sludge using nitrate nitrogen and
CODcr in sewage carries out denitrification, nitrate nitrogen is converted into molecular nitrogen, escapes into air and effectively taken
Remove, reach simultaneously toward the effect except BOD5 and denitrogenation.But A/O factures are extremely difficult to for the processing of aquaculture wastewater
COD400mg/L, below ammonia nitrogen 80mg/L processing requirement.
As can be seen here, above-mentioned existing A/O factures have still suffered from deficiency, and are urgently further improved.How
A kind of new culturing wastewater processing system and method are founded, the BOD5 preferably removed in sewage, CODcr, nitridation is reached
The purpose of compound, improved target is needed as current industry pole.
