In step 3 2. described in artificial distribution composition are as follows: MgSO4·7H2O, 0.08g/L；KNO3, 0.15g/L；KH2PO4,
0.015g/L；CaCl2, 0.04g/L and microelement, 1ml/L；The artificial distribution prepares by the following method: will
0.08g MgSO4·7H2O、0.15g KNO3、0.015g KH2PO4、0.04g CaCl21L distillation is dissolved into 1mL microelement
In water, the artificial distribution of 1L is obtained.
9. using as claimed in claim 4 a kind of using corncob as the denitrification filter pool reactor for treatment sewage of biomass carrier
Method, it is characterised in that using a kind of using corncob as the method for the denitrification filter pool reactor for treatment sewage of biomass carrier
It is completed by the following steps:
Sewage is added in water tank inlet (1), water inlet peristaltic pump (2), inlet valve (3) and multiple outlet pipes (5) are opened, it is dirty
Water is entered in reactor body by water inlet peristaltic pump (2), inlet valve (3) and water inlet pipe (4), in reactor body
Hydraulic detention time is 60min~70min, then the discharge from multiple outlet pipes (5), the sewage that obtains that treated；At interval of 20
It~30 days, valve (9) and backwash intake pump (10) are opened, clear water passes through backwash water inlet pipe (8), valve (9) and recoil
It washes intake pump (10) and enters in reactor body and backwashed, that adheres in removal biomass carrier (6) is old loose
Biomembrane；
The flow of inlet water of the reactor body are as follows: 0.6L/h~0.7L/h.
10. it is according to claim 9 using a kind of using corncob as the denitrification filter pool reactor for treatment of biomass carrier
The method of sewage, it is characterised in that the sewage index is COD, 53.8mg/L~56.2mg/L；NO3 -- N 18.7mg/L~
19.3mg/L；NO2 --N<0.9mg/L；TN, 18.2mg/L~19.8mg/L.
