Structure, Round Sump structure are taken up an area little, it is adaptable to newly-built sewage treatment plant；Split-type structural is more suitable for existing Sewage Plant low cost
Technological transformation.
A kind of operation principle of sewage disposal odor removal is：
After sludge is entered from enters mud pipe 111,111 opening upwards of enters mud pipe, and separated in concentrating and separating area 12, on
Clear liquid is concentrated in supernatant water leg 122, and is discharged through supernatant liquid pipe 123；Sludge is under gravity under central tube 112
Side flows out and falls on reflecting plate 113, and flow velocity is uniformly fallen deodorant sludge condensation and selects, in the sludge hopper 124 of 1 bottom of pond, to carry
The concentration of high deodorizing microorganism；The concentrated area's sludge out pipe 131 of the deodorant sludge concentrated by pond 1 is selected to flow through deodorant sludge condensation
To homogeneous culture storage pool 2,2 bottom of homogeneous culture storage pool is equipped with aerator 22, and the supporting air blast of biological tank is by sky
Feed channel 21 is connected to aerator 22, is 2 supplemental oxygen of homogeneous culture storage pool, recovers the activity of sludge.Sludge is through sludge out pipe
Road 23 is added to coagulation area and Treatment of Sludge area.
A kind of sewage disposal deodorizing method, including
Step one：Sewage flows through coagulation area, biological tank and second pond successively from water inlet pipe, and complete in the second pond
Become separation of solid and liquid, supernatant is discharged through drainpipe, sludge is back to the biological tank, the Treatment of Sludge area and deodorant dress respectively
In putting；
Step 2：Sludge activity recovery in the odor removal, and respectively stream to the coagulation area and dirt
Mud treatment region, for the odorant pollutant for removing source and issuable foul gas, the sewage mixed after deodorant sludge is turbid
Degree is less than 200NTU, the H in surrounding enviroment2S concentration is less than 1ppm；Described in the odor removal, deodorant sludge condensation selects pond
1 deodorant condition is：In 20g/L-25g/L, the time of staying of sludge is 3h-6h to the control of outlet sludge concentration；The homogeneous training
The condition of culture of foster storage pool 2 is：In 0.4mg/L-1mg/L, the time of staying of sludge is 0.5-1h for dissolved oxygen control.
The odor removal is located at the Treatment of Sludge area.
As shown in figure 3, the course of work of embodiment one is：
Add the odor removal of Round Sump structure in conventional activated sludge process biological sludge treatment region.
Sewage flows through coagulation area, biological tank, second pond successively from water inlet, and in second pond separation of solid and liquid, supernatant
Discharge through drainpipe, air blast is responsible for supplying to biological tank aerating system.Second pond is returned through the partial reflux sludge that draining is produced
Biological tank is flowed, the deodorant sludge reflux with respect to the 1%-2% of wastewater influent amount selects pond 1 to deodorant sludge condensation, other
Excess sludge flows into Treatment of Sludge area and is processed.The deodorant sludge concentrated by pond 1 is selected by dense through deodorant sludge condensation
Contracting area sludge out pipe 131 flow to homogeneous culture storage pool 2, and 2 bottom of homogeneous culture storage pool is equipped with aerator 22, and biological tank is supporting
Air blast aerator 22 is connected to by air duct 21, be 2 supplemental oxygen of homogeneous culture storage pool, recover sludge work
Property.Sludge is added to coagulation area and Treatment of Sludge area respectively through mud extraction pipeline 23, for removing the source in coagulation area
Head odorant pollutant, and issuable foul gas in Treatment of Sludge area is processed.
According to above-mentioned process control parameter, by PLC and the real-time control of in-line meter, the intelligence for realizing the technique is accurate
Control：After adding deodorant sludge, H2The control of S concentration controls in below 200NTU in below 1ppm, turbidity.Control logic is for relying on
H is carried out to the instantaneous water yield, the Linear Control of turbidity and fuzzy control2The accuracy controlling of S concentration.And can realize according to historical data
Automatically analyze adjustment control parameter.
