Description
Technical field
The present invention relates to a kind of Quick percolation apparatus and the methods for carrying out sewage treatment using it, belong to sewage disposal technology
Field.
Background technique
The removal of ammonia nitrogen in sewage is important performance assessment criteria.Conventional technique generally takes A2/ O, A/O, SBR, segmentation
Aerated oxidation ditch etc..
These techniques are required to a nitrification tank or nitration section, are then refluxed for anaerobic pond (or anaerobism section) just playing instead
Nitrify denitrification.It is required that controlling strictly sludge age in nitrification tank, to ensure longer sludge age, preferable nitrification is just had
Effect.Therefore the reflux ratio of whole system requires larger, and whole energy consumption is higher.The construction cost of multiple reaction tanks, management difficulty
It is higher.
The deficiencies of techniques such as Anammox, short-cut nitrification and denitrification, it is poor that there is also technology stabilities, and application is poor, no
It is main denitrification process to be applied.
Quickly diafiltration is a kind of Novel sewage eco-treatment technology developed in recent years, is applicable not only at sanitary sewage
Reason, the purification for being also admirably suitable for polluted river water improve.The technology mostly uses the good crude media of permeance property as master
Material is percolated instead of natural soil layer, the advantage of artificial swamp and conventional soil filtration system is combined, particularly suitable for sewage
Source dispersion, the incomplete rural area of sewage treatment facility or outlying district.Traditional rapid infiltration system is to low-concentration ammonia-nitrogen (NH3-
N < 50mg/L) removal effect it is preferable, it is often insufficient up to 80% or more, however poor to the removal effect of total nitrogen (TN)
30%, it is difficult to qualified discharge.When ammonia nitrogen in sewage concentration is higher, conventional filtration system treatment effect is poor.
In consideration of it, it is necessary to study a kind of new Quick percolation apparatus, so as to solve the deficiencies in the prior art.
