Sufficient different periods effluent quality requirement.
In order to realize above scheme, the utility model provides a kind of sewage treatment bioselection zone device, including according to
Anaerobic pond, anoxic pond and the aerobic tank of secondary connection, the bottom of the anaerobic pond, anoxic pond and aerobic tank pass through respectively aeration tube with
Aeration supervisor's connection, the aeration supervisor connect with Aeration fan, and intake valve is separately installed in each the aeration tube, described to detest
The upper end in oxygen pond, anoxic pond and aerobic tank is each described to divide on water inlet pipe respectively respectively by dividing water inlet pipe to be connected to water inlet manifold
Inlet valve is installed, the aerobic tank is connected to sedimentation basin.
The utility model sewage treatment bioselection zone device, wherein the anaerobic pond, anoxic pond and aerobic tank respectively by
It is divided at least one region, each leads into the aeration tube in the anaerobic pond, anoxic pond and each region of aerobic tank.
The utility model sewage treatment bioselection zone device is located at pond wherein aeration supervisor is located at pond body two sides
Interior each the aeration tube uses hose.
The utility model sewage treatment bioselection zone device, wherein the dissolved oxygen in the anaerobic pond is less than 0.2mg/L,

After adopting the above scheme, the utility model sewage treatment bioselection zone device can according to water water quality difference into
The flexible hand-off process of row, when total nitrogen is higher in water, by the first inlet valve on anaerobic pond, anoxic pond and aerobic tank, second into
Water valve and third inlet valve control each pond Inlet and outlet water position；When total nitrogen is higher in water, denitrogenation AO technique is realized in adjustment；It is total in water
When phosphorus is higher, dephosphorization AO technique is realized in adjustment；According to the variation of water temperature, aeration quantity is adjusted by controlling each intake valve, avoids water
The too low generation sludge bulking of middle dissolved oxygen or dissolved oxygen is excessively high that sludge aging, effluent quality is caused to be deteriorated, structure design letter
Single, using flexible can meet different discharge standards, and the stop of each process section of appropriate adjustment can be carried out according to water temperature, change of water quality
Time, aeration quantity can save energy consumption and generally meet different periods effluent quality requirement.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model sewage treatment bioselection zone device.
Specific embodiment
As shown in Figure 1, the utility model sewage treatment bioselection zone device includes the anaerobic pond 1 in turn switched on, anoxic
Pond 2 and aerobic tank 3, aerobic tank 3 are connected to sedimentation basin 20.Dissolved oxygen in anaerobic pond 1 is less than 0.2mg/L, molten in anoxic pond 2
It solves oxygen and is less than 0.5mg/L, the dissolved oxygen in aerobic tank 3 is 1.8mg/L-2.2 mg/L.
The inner cavity of aerobic tank 3 is divided into three regions, each regional connectivity, anaerobic pond 1, anoxic by upper spacer 4 and lower clapboard 5
The bottom in pond 2 passes through the first aeration tube 6 respectively, the second aeration tube 7 is connected to aeration supervisor 8, the first aeration tube 6, second aeration
The first intake valve 9 and the second intake valve 10 are separately installed on pipe 7, each region of aerobic tank 3 passes through third aeration tube 11 respectively
It is connected to aeration supervisor 8, third intake valve 12 is separately installed on each third aeration tube 11, aeration supervisor 8 connects with Aeration fan
It connects.Aeration supervisor 8 is located at the air inlet of pond body two sides, avoids aeration uneven, the first aeration tube 6, the second aeration tube 7 in pond
And third aeration tube 11 is all made of hose, setting in this way can be overhauled in the case where not influencing system operation.
The upper end of anaerobic pond 1, anoxic pond 2 and aerobic tank 3 pass through respectively first point of water inlet pipe, 13, second points of water inlet pipes 14 and
Third divides water inlet pipe 15 to be connected to water inlet manifold 16, and first point of water inlet pipe, 13, second points of water inlet pipes 14 and third divide water inlet pipe 15
