Description
Technical field
The present invention relates to sewage disposal systems, wet more particularly to a kind of Anammox type for high nitrogen sewage disposal
Ground system.
Background technology
With China's rapid economic development, agricultural or food production sewage yield also increasingly increase, while such sewage
There is also the higher features of nitrogen content.By taking livestock and poultry cultivation sewage as an example, important composition of the livestock and poultry breeding industry as China's agricultural
The discharge capacity of part, nitrogen is 102.48 ten thousand tons, accounts for the 21.7% of the nitrogen discharged total amount in the whole nation, and total nitrogen contains in livestock and poultry cultivation sewage
Amount is about 400-1500 mg/L.Therefore, the Important Problems as the Chinese government and social concerns high nitrogen sewage are effectively treated.
In general, such sewage disposal mainly uses biological treatment, nitrogen is realized using aerobic nitrifying process and anaerobic denitrifying process
The removal of element, but since traditional anaerobic denitrifying process needs a large amount of carbon source materials, to cause, processing cost is higher to ask
Topic.For this present situation, Anammox treatment process increasingly mature in recent years to solve the problems, such as that this provides new approach, but
Be due to anaerobic ammonia oxidation microbiological there are growth rates slowly, environmental requirement is higher and the spies such as capacity of resisting impact load is weaker
Property, traditional bioreactor stability during handling this high nitrogen sewage is weaker, and reaction system operation is complex,
How to build a kind of low-carbon, stabilization and simple Anaerobic ammonium oxidation system becomes the focal point of high nitrogen sewage treatment field.
Artificial swamp is a kind of ecological wastewater processing technique to grow up the 1970s, it be by manually building and
The ground similar with marshland for controlling operation, by sewage, sludge controlled dosing to the wetland through manually building, sewage
With sludge in a certain direction flow during, mainly utilize soil, artificial dielectric, plant, the physics of microorganism, chemistry,
The triple synergistic effects of biology, a kind of technology that sewage, sludge are handled.Its mechanism of action include absorption, be detained, filtering,
Redox, precipitation, microorganism decomposition, conversion, plant masking, residue accumulated, water transpiration and Nutrient Absorption and all kinds of dynamic
The effect of object.Artificial swamp unit is made of plant, microorganism, filler and animal, and each constituent plays different works respectively
With, and mutually act synergistically so that entire Constructed Wetland Ecology System equilbrium running plays good purification function.At this
Wet land filler plays decisive skeleton function in a little units, and wet land filler first has the works such as filtering, precipitation, absorption and flocculation
With the suspended matter in water body being effectively removed, secondly wet land filler is that the growth of plant and microorganism and oxygen are transmitted and provided
Necessary requirement.Currently, being directed to different sewage type, many kinds of substance has been chosen for wet land filler, for example, soil, volcanic rock,
Cinder, red soil, brick, extra large oyster shell, zeolite, haydite, cobble etc..Since there are hydraulic detention time is longer and anti-impact for wet land system
The stronger characteristic of load-bearing capacity is hit, therefore the mechanism is can guarantee as the effect carrier of anaerobic ammonia oxidation microbiological
Stabilization effect, and simplify process operation program.
