Description
Technical field
The utility model is related to technical field of sewage, more particularly to a kind of denitrification filter pool.
Background technology
Nitrogen pollutant in sewage treatment area, removal water body is important link, and the removal of nitrogen pollutant
It is critical only that denitrification, therefore, at present, denitrification filter pool is generally acknowledged denitrogenation sharp weapon.Denitrification filter pool in the market
Two kinds are broadly divided into, a kind of is the denitrification filter pool of gravity streaming, is carried out when the filter of the type is different from backwash, filtered
When, filtered from top to bottom, then need to stop intaking during backwash, washed away from bottom to top.It is another then be anti-continuous stream
Nitrification filter tank, sewage is carried out simultaneously by filter tank bottom up overflow, backwash with filtering, and bottom filtrate is by air-lift device through sand suction pipe
Top sand-washing device, the sand after sand-washing device is washed and the waste water to overflow, reaction are transported to, are so moved in circles.
But all there is its respective shortcoming in both denitrification filter pools：Gravity stream denitrification filter pool will to the water quality intake
Ask higher, it is gravity stream to be primarily due to it, and effluent flow rate is very fast, and the contact filtrate time is short, and the denitrifying load of filtrate can not be too
Nitrogen pollutant concentration in height, therefore sewage can not be too high, and filtrate utilization rate is low, and usage amount is big；And continuous stream denitrification
Then there is preferable clearance in filter tank for the nitrogen pollutant of higher concentration, for low concentration nitrogen pollutant treatment effect then
It is not good, and although its washed-out sand is continuous, but have that washed-out sand is not clean, the problem of local washed-out sand.In actual use, it is dirty
Water factory generally only can select one kind therein due to cost considerations, and the sewage larger this results in change of water quality cannot be tackled
Problem, and each single backwash of two kinds of denitrification filter pools or washed-out sand mode cannot also tackle the various situations of filtrate.
Through retrieval, Chinese utility model patent application, publication number：CN102063115A, publication date：2011.05.18, it is public
A kind of real-time automatic backwashing control system of denitrification filter tank and operation method have been opened, the online water in denitrification filter pool has been provided with
Turbidity transducer, nitrate sensor and turbidimetry, nitric acid salt determinator, are additionally provided with process controller and industrial computer, mistake
Range controller is provided with into water pump relay, the multiple relays of water inlet valve relay etc., these relays through interface sequentially respectively with
Corresponding pump and Valve controlling connection；The clear water reserviors be additionally provided with the outlet pipe that is connected with denitrification filter pool filter material layer top and with
The storage basin of denitrification filter pool top connection.The operation method of Back Washing Control System, its feature is comprised the following steps：1 starts
Control system；2 parameter processings judge；3 drainage procedures；4 independent gas backwashes；5 combined water and air backwashes；6 single water backwashs are washed.
The utility model is applied to town sewage advanced treating and nitrogenous Industrial Wastewater Treatment, but temporarily under test, is applied to
During sewage disposal, efficiency is poor.
