It is very little etc., be also not limited to described in the present embodiment, can be used in this field other conventional filling kinds and corresponding parameter into
Row loads.
Composite flow manual-rapid infiltration ecological bed provided by the utility model, the removal principle to organic matter, nitrogen, phosphorus is:
(1) to the removal principle of organic matter: waste water is contacted with filler flowing for a long time, gradually forms biology in filler surface
Film.Since the surface area of filler particles in each bed is very big, and it is attached with well-grown biomembrane, therefore, sewage can be made
In organic matter be adsorbed, removed from water rapidly.Dry reoxygenation phase, micro- life are fallen in level-one packet air-bed 8 and secondary packet air-bed 15
A portion is used to synthesize new cellular material using organic matter as nutriment by object, and another part then passes through oxidation
The synthesis for obtaining energy supply neoblast is decomposed, so that most of organic matter be enable to degrade, reaction process can be sketched are as follows: complicated
Organic matter+O2→CO2↑+H2O+ stable product.In addition, organic matter can be used as denitrifying being detained in bed 10 and full water bed 12
Carbon source not only ensure that going on smoothly for denitrification process, but also can further decrease the concentration of outlet water organic substance.Meanwhile it is organic
Object is also possible to remove by anaerobic metabolism, and reaction process can be sketched are as follows: complicated organic matter → CO2↑+CH4↑+unstable product, by
Slow in anaerobic metabolic process, the effect is relatively small to the contribution of organic matter removal.
(2) to the removal principle of nitrogen: sewage penetrates into level-one packet air-bed 8, the nitrogen pollutant in the waterflooding phase, in sewage first
It is trapped or is adsorbed on the surface of filler particles, is falling dry spell, level-one packet air-bed 8 starts reoxygenation, micro- life of filler surface attachment
Object is by nitrification by mineralized nitrogen at nitrite nitrogen or nitrate nitrogen: NH4 +→NO2 -→NO3 -；Subsequently into be detained bed 10, by
It is located at 8 lower section of level-one packet air-bed in being detained bed 10, reoxygenation effect is poor, and part nitrate nitrogen is made under anaerobic environment by denitrification
It is removed with gaseous form is converted to: NO3 -→NO2 -→NO→N2O→N2；Full water bed 12 is subsequently entered, due to water bed 12 of satisfying
Contour and bottom is interconnected with delay bed 10, is constantly in waterflooding state, ensure that good scarce/anaerobic environment, simultaneously
Also hydraulic detention time is extended, the further removal of nitrogen pollutant is conducive to.When the water inlet of next period, it is detained bed 10
Sewage enters full water bed 12 in level-one packet air-bed 8 under the pressure of sewage, the water outlet of full water bed 12 enters secondary packet air-bed 15, leads to
Cross waterflooding -- the natural reaeration process for falling dry alternate run further strengthens ecological bed denitrification effect.
(3) to the removal principle of phosphorus: the composite flow manual-rapid infiltration ecological bed is to there are mainly three types of the removals of phosphorus element pollutant
Approach: first is that the assimilation of microorganism, phosphorus is used as indispensable nutriment in microorganism growth metabolism by microorganism
In synthesis Self substances or it is converted into ATP；Second is that since the dissolved oxygen content of different zones in bed has differences, aerobic and anaerobism
Environment is alternately present, the excess accumulation for being conducive to phosphorus and excessively release；Third is that the physics chemical action of filler, main includes absorption
It with two aspects of chemical precipitation, is combined using a variety of fillers, there is good absorption and rejection effect to phosphorus element pollutant,
And zeolite sand, shale sand etc. is used to be used as filler, wherein chemistry can occur with soluble phosphate for Ca, Fe and Al for being rich in etc. instead
It answers, solubility low calcium phosphate, ferric phosphate or aluminum phosphate is generated, to enhance the dephosphorization ability of bed.
The utility model is described further below by experimental example, further show the utility model the advantages of and
Principle, in following two experimental examples, inhalant region 6, level-one packet air-bed 8 are detained bed 10, full water bed 12, secondary packet air-bed 15
Height is respectively 10cm, 50cm, 30cm, 30cm, 30cm, buffer layer 1, separate layer 9, connectivity layer 11, buffer layer 2 13, support
The height of layer 16 is 2cm.

Collaborate manual-rapid infiltration ecological bed.Carrying out practically parameter is as follows: 25 DEG C of room temperature or so, hydraulic loading 0.3m3/(m2D), it transports daily
1:1,1:2,1:3 is respectively adopted in 3 periods of row, each periodic duty 8h, wet-dry ratio, detects 1~2 effluent quality daily.Knot
Fruit is as shown in table 1:
Table 1: certain rural household's life wastewater treatment efficiency
Experimental example 2
The sanitary sewage of composite flow manual-rapid infiltration ecological bed processing is derived from Chengdu Pixian County villages and small towns community, main water quality
Index is as follows: COD concentration is 200~350mg/L, NH3- N concentration is 30~50mg/L, TN concentration is 35~60mg/L, TP is dense
Degree is 2~5mg/L, SS concentration is 100~300mg/L, pH value is 7.0~7.8.Sewage is after the pretreatment of simple precipitation and separation
Into composite flow manual-rapid infiltration ecological bed.Carrying out practically parameter is as follows: 25 DEG C of room temperature or so, hydraulic loading 0.2m3/(m2D),
1:1,1:3,1:5 is respectively adopted in 2 periods of operation, each periodic duty 12h, wet-dry ratio daily, detects 1~2 water outlet daily
Water quality.The results are shown in Table 2:
Table 2: certain villages and small towns community's life wastewater treatment efficiency
The main item controlled highest of effluent quality and " integrated wastewater discharge standard (GB8978-1996) " is allowed to discharge
Concentration, which compares, to be obtained, and when handling certain rural household's life sewage and certain villages and small towns community's life sewage, be discharged COD, NH3-N、SS
Concentration can reach " integrated wastewater discharge standard (GB8978-1996) " primary standard, also can reach certain removal to TN, TP
Effect.Difference is, when handling certain rural household's life sewage, can get more preferably treatment effect under conditions of wet-dry ratio 1:3, and
When handling certain villages and small towns community's life sewage, more preferably treatment effect can get under conditions of wet-dry ratio 1:5, this is because compound
Turning flow artificial rapid infiltration ecological bed is closely related to the factors such as the treatment effect of sanitary sewage and influent quality, hydraulic loading, wet-dry ratio.
In general, being contemplated that appropriate reduction hydraulic loading or extension fall the dry time, to obtain when pollutional load of intaking is higher
More ideal wastewater purifying efficiency.
