Description
Technical field
The utility model relates to water treatment field, is specifically related to a kind of subregion inlet type A2/ O sewage treatment unit.
Background technology
A2/ O and sequencing batch active sludge (SBR) are the common technique with higher COD removal and denitrogenation dephosphorization effect, existing A2/ O and modified form A2/ O technique denitrogenation dephosphorizing and reflux ratio are closely related. Too low reflux ratio difficulty has desirable denitrogenation dephosphorizing effect, but too high reflux ratio also detests (lacking) oxygen section dissolved oxygen (DO) too high levels because causing and difficulty has higher denitrogenation effect and releases phosphorus ability, too low (lacking) oxygen section of detesting releases the super amount suction phosphorus that phosphorus ability must be difficult to obtain aerobic section microorganism. Therefore, existing A2/ O and modified form A2In/O art breading sanitary sewage process, general restriction muddy water mixed solution and return sludge ratio in more among a small circle, denitrogenation effect of system and to inhale phosphorus ability lower.
Practical novel content
The purpose of this utility model is for solving above-mentioned deficiency, it is provided that a kind of subregion inlet type A2/ O sewage treatment unit.
The purpose of this utility model is achieved through the following technical solutions:
A kind of subregion inlet type A2/ O sewage treatment unit, comprise water inlet pipe, control valve, intake pump, 2nd anaerobic pond, first anaerobic pond, first anoxic pond, 2nd anoxic pond, Aerobic Pond, aeration valve, mixed-liquor return pump, sludge reflux pump, air compressor, second pond and water outlet, control valve is arranged on the 2nd anaerobic pond bottom, water inlet pipe connects intake pump, 2nd anaerobic pond is arranged on the right side of intake pump, first anaerobic pond and the 2nd anaerobic pond are placed side by side, 2nd anoxic pond is arranged on the right side of the 2nd anaerobic pond, first anoxic pond and the 2nd anoxic pond are placed side by side, Aerobic Pond is arranged on the first anoxic pond and the right side of the 2nd anoxic pond, aeration valve connects Aerobic Pond, mixed-liquor return pump connects second pond, sludge reflux pump one end connects bottom second pond, the other end connects the 2nd anaerobic pond and the first anaerobic pond, air compressor connects Aerobic Pond, water outlet is connected on the right side of second pond.
The utility model also has some technology features like this:
Aerobic Pond bottom is provided with sewage draining exit.
Second pond bottom is also provided with excess sludge discharge mouth.
Intake pump connects the 2nd anaerobic pond and the first anaerobic pond by subregion water inlet pipe.
The utility model has effect useful as follows:
The utility model is reasonable in design, it may also be useful to convenient, water treatment efficiency is good, the quality height of water, and good denitrogenation and dephosphorization effect, has good application prospect.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of subregion inlet type A2/ O sewage treatment unit, comprises water inlet pipe 16, control valve 1, intake pump 2, 2nd anaerobic pond 3, first anaerobic pond 4, first anoxic pond 5, 2nd anoxic pond 6, Aerobic Pond 7, aeration valve 8, mixed-liquor return pump 9, sludge reflux pump 11, air compressor 12, second pond 13 and water outlet 14, control valve 1 is arranged on the 2nd anaerobic pond 3 bottom, water inlet pipe 16 connects intake pump 2,2nd anaerobic pond 3 is arranged on the right side of intake pump 2, first anaerobic pond 4 and the 2nd anaerobic pond 3 are placed side by side, 2nd anoxic pond 6 is arranged on the right side of the 2nd anaerobic pond 3, first anoxic pond 5 and the 2nd anoxic pond 6 are placed side by side, Aerobic Pond 7 is arranged on the first anoxic pond 5 and the right side of the 2nd anoxic pond 6, aeration valve 8 connects Aerobic Pond 7, mixed-liquor return pump 9 connects second pond 13, sludge reflux pump 11 one end connects bottom second pond 13, the other end connects the 2nd anaerobic pond 3 and the first anaerobic pond 4, air compressor 12 connects Aerobic Pond 7, water outlet 14 is connected on the right side of second pond 13, Aerobic Pond 7 bottom is provided with sewage draining exit 10, second pond 13 bottom is also provided with excess sludge discharge mouth 15, intake pump connects the 2nd anaerobic pond and the first anaerobic pond by subregion water inlet pipe 16.
Principle of work: intake in the anaerobic pond and anoxic pond that flow to First Series respectively with certain proportion through constant flow pump, connect stirring action with Aerobic Pond, the mixed solution of settling tank backflow, mud at stirrer, active sludge microorganism is fully contacted and organic matter degradation, denitrogenation occur and releases phosphorus reaction with the pollutent matrix in sewage; Then, the muddy water mixed solution of anoxic pond flow to Aerobic Pond carry out nitration reaction and inhale phosphorus reaction; Finally, muddy water mixed solution flow to second pond and realizes sewage purification as mud-water separation; Part sludge reflux anoxic pond, another part mud is then discharged into outside system with the form of excess sludge. When First Series runs with above-mentioned running status, second series is in quiet state of having a rest. During next alternate run state, then the two residing states of series are contrary. Whole experimentation, the alternate run of first, second two series achieves dirty water purification. In the whole service process of system, the time that first, second series is run separately continuously is two series alternate run time (DAOT), and Aerobic Pond is in continuous running status.
