Description
Technical field
The present invention relates to sewage disposal system, more particularly to a kind of anti-blocking medium enhanced type to be quickly percolated sewage disposal system
System.
Background technology
Statement in this part merely provides the background information relevant with present disclosure, thereby increases and it is possible to does not form
Prior art.
Artificial rapid infiltration system (CRI) develops on the basis of sewage rapid infiltration system and artificial swamp.CRI systems
System by grid pond, preliminary sedimentation tank, ooze pond soon and outlet system forms, in pond is oozed soon, fill by natural sand, Dali stone sand,
The Artificial filtering material that zeolite sand etc. forms by a certain percentage, CRI systems carry out sewage disposal using the drive manner of alternation of wetting and drying.
CRI systems are realized by absorption, retention and decomposition of the microorganism on filtrate and filtrate surrounding biologic film to pollutant in water
To the purification process of waste water.
Anaerobism section (denitrification layer) in traditional CRI systems, because hydraulic detention time is shorter, C/N is not belonging to than small
Completely full pool, it is not thorough that oxyty height causes anti-nitration reaction to carry out.Nitrification simply changes nitrogen in CRI systems
Form, the organic nitrogen in water inlet and ammonia nitrogen are simply converted into nitrate nitrogen by nitrification, and anti-nitration reaction is carried out
It is very insufficient, therefore effectively nitrate nitrogen can not will be changed into nitrogen, permanent to be removed from system, here it is CRI systems
Ammonia nitrogen removal frank is very high and the reason for nitrogen removal rate deficiency.
Nitrifier is autotrophy aerobic bacteria, and growth generation time is long, sensitive to environmental change, slow-growing.It is formed at filtrate
The nitrifier biomembrane of dielectric surface is easy to fall off, therefore the recovery of water body ammonia oxidation bacteria function takes long enough.
Denitrifying bacterium is heterotrophism anaerobic bacteria, and denitrifying bacterium growth needs decomposing organic matter to provide energy, anti-nitration reaction master
Occur to carry out in lower floor's filtrate medium of anaerobic condition, because retention of the upper strata filtrate to organic matter causes to reach lower floor Jie
Anhydrous middle organic matter can not meet the metabolism needs of denitrifying bacterium during matter filtrate, cause sewage nitrogen removal rate not high；
Blockage problem is one of important content of the sewage disposal system research such as artificial rapid infiltration system and artificial swamp.
It not only influences the hydraulic load of system, and can greatly shorten the service life of system.It has been generally acknowledged that cause system jams
The reason for mainly by the retention of suspension, absorption, and the growth of microbial film is the main reason for resulting in blockage.
Therefore prior art has much room for improvement and developed.
