Logical, sewage passes sequentially through the downlink flow chamber and uplink flow chamber of each compartment, and anaerobic baffled reactor 1 can not only play buffering
Effect, and can be improved the biodegradability of sewage, sewage gradually removes COD followed by four compartments, and sewage flows through the 4th
Compartment 6 enters compound bio trickling filter 10 through overflow weir 8 and semi-canal type overflow water distributor 9.
The filtration stage the following steps are included:
Step (1) cloth water chamber: the water outlet of anaerobic baffled reactor 1 enters semi-canal type overflow water distributor 9 by overflow weir 8 and drips
The punched-type water distributing plate 18 that 14 housing tip of level-one biofilter is set up is dropped down onto, is flowed by the plate hole of the punched-type water distributing plate 18
Level-one biofilter 14；
Step (2) level-one biofilter: level-one biofilter 14 is provided with haydites of book structure filler, in level-one draft chamber 20
Under oxygen supply effect, from anaerobic environment gradually to aerobic environment transition, heterotroph utilizes carbon source mass propagation for level-one biofilter 14,
COD is largely removed in sewage, and part organic nitrogen is converted into ammonia, the biomembrane effect of filler surface and aerobic-hypoxic microenvironment
The synchronous nitration and denitrification effect of lower progress removes a part of nitrogen, after successively drip grid type splash board 17 and two thereunder
The punched-type water distributing plate 18 of 15 housing tip of grade biofilter, sewage sufficiently fill in level-one draft chamber 20 in moisture film or drops
Oxygen flows into two stage biological filter tank 15；
Step (3) two stage biological filter tank: two stage biological filter tank 15 is provided with sponge+sponge Iron-complex-filling, logical in level-one
Under the common oxygen supply effect of air compartment 20 and second level draft chamber 21, two stage biological filter tank 15 is under aerobic environment, and it is raw to flow into second level
Sewage in object filter tank 15 is through PO4 3-+Fe3+→FePO4Phosphorus effect and filler itself suction-operated dephosphorization are inhaled in ↓ effect, polyP bacteria,
16 shell of grid type splash board 17 and three-level biofilter similar with described in step (2) afterwards, being successively dropped in below its shell
The punched-type water distributing plate 18 on body top, sewage are sufficiently oxygenated in second level draft chamber 21 in moisture film or drops, and it is raw to flow into three-level
In object filter tank 16；
Step (4) three-level biofilter: three-level biofilter 16 is provided with haydites of book structure filler, in second level draft chamber 21
Oxygen supply effect under, from aerobic environment to anaerobic environment transition, it is good that sewage flows through three-level biofilter 16 for three-level biofilter 16
Oxygen environment section, nitrobacteria mass propagation are converted into NO through a large amount of nitrogen in nitrification sewage3 -And NO2 -Form exist,
The synchronous nitration and denitrification effect carried out under the biomembrane effect of filler surface and aerobic-hypoxic microenvironment removes a small amount of nitrogen, after
Flow through 16 anaerobic environment section of three-level biofilter, the NO in sewage3 -And NO2 -The nitrogen of form is converted into N by denitrification2Row
Out, a large amount of nitrogen are removed, is discharged through water outlet 11, purified water can be obtained, effectively remove the polluter in sewage, so that sewage
Qualified discharge.
The technique biofilter is by no-power air blower 13, the wind-drawing effect of ventilation duct 12, grid type splash board 17 and wears
The splashing reoxygenation of cellular type water distributing plate 18 acts on oxygen supply.
It is formed with certain voidage between the filler particles in every grade of biofilter, can be formed in the outer surface of particle
Local aerobic-hypoxic microenvironment, when water flow flows through the filter tank for loading filler, the difference of the inside and outside flow rate of water flow of filler easy to form
It is different, further, since the inside and outside oxygen supply condition of filler difference, can mention for the microorganism to play a role in sewage disposal process
For suitable living environment, treatment effeciency can be improved.
The present apparatus uses buried installation, and winter can operate normally, and water outlet can be used for afforesting, flush the toilet, and is conducive to disperse
The popularization and application of formula rural domestic sewage treatment.
