Description
Technical field
The present invention relates to it is a kind of for carbon source in sewage and phosphorus recycling and autotrophic denitrification process, belong at sewage
Manage technical field, the sanitary sewage disposal suitable for city and rural area, it can also be used to handle high organic concentrations waste water, both can solve
The pollution problem of nitrogen phosphorus in sewage, while Resource recovery and the energy.
Background technique
Organic matter in sewage contains huge chemical energy.By taking COD concentration 500mg/L as an example, the energy contained is about
17.7~28.7 kJ/g COD are folded to maximum ton water power consumption about 22.55 kWh/m3, extractible chemical energy about 1.5
~1.9 kW·h /m3, and energy consumption about 0.45 kWh/m needed for handling one ton of sewage at present3, it means that contained in sewage
Organic chemistry can be nearly 5 times for carrying out handling required energy consumption to it, capture extract part COD chemical energy then lead to
It crosses cogeneration of heat and power and is converted into electric energy, the complete self-supporting energy that can even become that energy consumption theoretically may be implemented exports factory.The whole world
Phosphorus exhaustion crisis is more and more severeer, and contains a large amount of phosphorus in sewage.500 x 10 of Global land phosphorus reserves at present8T, it is contemplated that
It can be exhausted in 100 years, therefore excavate " the second phosphorus ore "-recycling phosphorus from sewage just to become research hotspot, pass through the circulation benefit of phosphorus
With can be relieved phosphor resource exhaustion crisis.
By " carbon capture ", " phosphorus recycling " technology, " pollutant removal " and " energy, resource reclaim " are combined into one, changed
The energy conversion for becoming carbon source, does not generate pollution transfer, really realizes sustainable development idea, to the greatest extent " capture " by carbon source
Energy is extracted for anaerobic methaneization, phosphate fertilizer is produced by guanite recovery technology etc., is realized by Anammox and is not necessarily to carbon
Source, the autotrophic denitrification mode for reducing energy consumption and sludge yield.
Summary of the invention
The present invention is to provide it is a kind of for carbon source in sewage and phosphorus recycling and autotrophic denitrification process, solve
