Abstract
A flowing upward anaerobic ammonia oxidizing reactor with biologic membrane is composed of a cylindrical main body with water inlet tube, gas outlet tube and water outlet tube, the soft filler hung in said main body, and the denitrating biologic membrane for inoculating sludge to start said reaction. Its advantages are not blocking and high dechlorination effect.
Description
Technical field
The present invention relates to a kind of upflow type anaerobic ammonia oxidation biomembrane reaction apparatus, it can be held effectively and stay anaerobic ammonia oxidation microbiological.
Anammox is a kind of with NH
4 +For electron donor, with NO
2 -New biological denitrificaion reaction for electron acceptor(EA) has the excellent development application prospect in the wastewater biological denitrificaion field.But, the anaerobic ammonia oxidizing bacteria poor growth, in the Sludge Bed Anammox reaction unit that adopts at present, mud is easy to run off, and causes reaction unit longer start time, has limited this The Application of Technology.
Summary of the invention
The purpose of this invention is to provide a kind of upflow type anaerobic ammonia oxidation biomembrane reaction apparatus.
It has the reaction unit body, hangs soft-filler in the reaction unit body, and reaction unit body bottom is provided with water inlet pipe, and the reaction unit bodies top is provided with escape pipe, and reaction unit body upper side is provided with rising pipe.
The present invention adopts column or cube-shaped device, and interior extension soft-filler is the startup that seed sludge carries out the Anammox reaction unit with the denitrification biofilm, reaches to accelerate the purpose that the Anammox reaction unit starts.The upflowing water intake mode can make into water thorough mixing, avoids stopping up, and the soft-filler low price can effectively be held and stay microorganism, improves the biomass in the reaction unit.With the denitrification biofilm is that seed sludge can successfully start upflow type anaerobic ammonia oxidation biomembrane reaction apparatus in 3 months, and can obtain the denitrification effect of stability and high efficiency.
Description of drawings
Accompanying drawing is a upflow type anaerobic ammonia oxidation biomembrane reaction apparatus structural representation.
Embodiment
Upflow type anaerobic ammonia oxidation biomembrane reaction apparatus has column or cube-shaped reaction unit body, in the reaction unit body, hang soft-filler 1, reaction unit body bottom is provided with water inlet pipe 2, and the reaction unit bodies top is provided with escape pipe 4, and reaction unit body upper side is provided with rising pipe 3.The reaction unit body adopts steel or Steel Concrete to make up, reaction unit body aspect ratio 5: 1～10: 1, and big volume reaction unit adopts the lattice assembling.Soft-filler upper end is at the water surface below 5～10 centimetres, 15～25 centimetres of following end distance reaction unit bottoms.Reaction unit adopts the upflowing water intake mode, adopts the perforation water distributor to intake from the bottom.Reaction unit adopts denitrification biofilm to carry out the startup of Anammox biomembrane reaction apparatus.The reaction unit body is a column or cube-shaped.
As shown in the figure, reaction unit is cylindric, and interior extension soft-filler forms microbial film with attached microbial.Waste water enters from reaction unit bottom water inlet pipe 2, and after formed Anammox microbial film was handled on the soft-filler 1 in reaction unit, from rising pipe 3 outflows on top, the gases such as nitrogen that reaction unit produces were discharged from the escape pipe 4 at top.Earlier cultivating denitrification biofilm in hanging with the reaction unit of soft-filler during startup, is the startup that seed sludge carries out the Anammox reaction unit subsequently with the denitrification biofilm, can successfully start upflow type anaerobic ammonia oxidation biomembrane reaction apparatus in 3 months.
