As shown in Figure 1, the active sludge treatment pond of capacity regulating function that what the utility model provided have comprise be communicated with successively along drainage flow direction biochemistry pool, water outlet lattice district 4 and second pond 5; Biochemistry pool is inner be provided with along drainage flow direction be communicated with successively anaerobic zone 1, oxygen-starved area 2 and aerobic zone 3, anaerobic zone 1 is communicated with the entrance of biochemistry pool, water outlet lattice district 4 is arranged on the water outlet side of aerobic zone 3, capacity regulating pump 9 is provided with in aerobic zone 3, capacity regulating pump 9 is communicated with water outlet lattice district 4, by carrying sewage to regulate the water level of aerobic zone 3 to water outlet lattice district 4; Water outlet lattice district 4 is communicated with by a connecting pipe with second pond 5, and the Chi Shui in water outlet lattice district 4 flows into second pond 5 by communicating pipe.
In above-described embodiment, sewage is by after being pumped into biochemistry pool, follow-up anaerobic zone 1 is entered by flow by gravity, oxygen-starved area 2, aerobic zone 3, owing to arranging capacity regulating pump 9 in aerobic zone 3, capacity regulating pump 9 is communicated with water outlet lattice district 4, while carry Chi Shui to ensure that second pond 5 is normally intake to water outlet lattice district 4, the water level of aerobic zone 3 can be reduced, also reduce the water level of biochemistry pool simultaneously, biochemistry pool can be made to have adjustment that enough remaining spaces carry out water level, in other words, the water outlet of biochemistry pool is set to gravity water outlet and the dual mode operated mode of pump drainage, at decreased influent flow or when stopping, still ensure a certain amount of water and discharge biochemistry pool, biochemistry pool is made to have certain pondage, regulate as the water inlet of receiving peak period and use, and when intaking peak, still can keep more balanced water displacement, to improve Biochemical Treatment, this active sludge treatment pool equipment technique is simple, it is reliably convenient to operate, energy efficient and construction investment, and outlet effect is good.
Wherein, in second pond 5, the first return sludge pump 10 can be set, first return sludge pump 10 is communicated with the entrance of biochemistry pool, particularly, first return sludge pump 10 is arranged on bottom second pond 5, be communicated with the entrance (being also the entrance of anaerobic zone 1) of biochemistry pool by a connecting pipe, the mud be deposited in second pond 5 can return to biochemistry pool by arranging of the first return sludge pump 10.
Wherein, be provided with the second return sludge pump 8, second return sludge pump 8 in aerobic zone 3 to be communicated with oxygen-starved area 2.Can the mud be deposited in aerobic zone 3 be returned to oxygen-starved area 2 by arranging of the second return sludge pump 8, use for sewage disposal, prevent the loss of active sludge.
Wherein, active sludge treatment pond of the present utility model also comprises the gas blower 15 and aeration head 7 that are connected, and gas blower 15 is arranged on outside biochemistry pool, and aeration head 7 is arranged on bottom aerobic zone 3.By gas blower 15 to aeration head 7 air-blowing, meet the supply of aerobic zone 3 oxygen; The bottom of anaerobic zone 1 and oxygen-starved area 2 is provided with submersible agitator 6, improves active sludge to the treatment effect of sewage.
Further, aerobic zone 3 inwall offers from the bottom to top successively low-water level mark 14, ordinary water level mark 13, capacity regulating watermark 12 and high water mark 11.
In the utility model, the aerobic zone 3 of biochemistry pool is generally run between low-water level mark 14 and high water mark 11, because water outlet lattice district 4 water level of biochemistry pool remains on high-water, intake to ensure to flow automatically to second pond 5, thus generally, need by capacity regulating pump 9, sewage to be promoted to water outlet lattice district 4 from aerobic zone 3 from water outlet lattice district 4 to the water inlet of second pond 5, then from flowing to second pond 5; The water yield of capacity regulating pump 9 should be suitable with the external reflux mud discharge sum of second pond 5 with the average treatment amount of Sewage Plant (in hour), when flooding quantity lower than time equal treatment capacity time, all measure when flow due to capacity regulating pump 9 still keeps, aerobic zone 3 water level will continue to reduce, thus make biochemistry pool be provided with a certain amount of volume adjusted.
When aerobic zone 3 water level be reduced to setting low-water level mark 14 time, capacity regulating pump 9 will shut down, with sewage after keeping in aerobic zone 3 process to the diluting effect had to a certain degree of intaking, guarantee wastewater treatment efficiency.While capacity regulating pump 9 stops, gas blower 15 can be out of service, with energy efficient.
When sewage continues to enter aerobic zone 3, aerobic zone 3 water level is made to be increased to aerobic zone 3 ordinary water level when marking 13 gradually, gas blower 15 starts startup optimization (now capacity regulating pump 9 still quits work), when aerobic zone 3 water level is increased to capacity regulating watermark 12, capacity regulating pump 9 is started working, by aerobic zone 3 water to pumping in water outlet lattice district 4, water outlet from flowing into second pond 5, completes biological process from water outlet lattice.Why capacity regulating pump 9 operation more delayed than gas blower 15, is ensure that biochemistry pool first will carry out the aerobic treatment of certain hour before starting draining, prevents effluent quality not up to standard.
Due to peak times section sewage quantity be higher than time equal flooding quantity, thus continuation goes up by the water level of aerobic zone 3, when reaching high water mark 11, aerobic zone 3 water level can be acted on by gravity flow, enter in water outlet lattice district 4 with the water of capacity regulating pump 9 pumping simultaneously, enter second pond 5 subsequently and complete precipitation process.
When after peak period, biochemistry pool flooding quantity lower than time equal flow, capacity regulating pump 9 still works on, biochemistry pool water level will constantly decline, after being reduced to low-water level mark 14, capacity regulating pump 9 quits work, and gas blower 15 also quits work simultaneously, rises to after corresponding height open once again respectively until water level.
Further, the height of second pond 5 can higher than the height of biochemistry pool, and in such cases, because the height of biochemistry pool is lower than the height in water outlet lattice district 4, the pond water of biochemistry pool can only be pumped into water outlet lattice district 4 by capacity regulating pump 9.Like this when having advanced treatment facility after second pond 5, as in the situations such as filter tank, can second lift pump house be set again, the construction investment and the energy consumption that avoid second lift increase, simultaneously, because second pond 5 absolute altitude can suitably be raised, under suitable design conditions, enough second ponds 5 highly can arrange the first return sludge pump 10 again, directly lean on gravity reflux to anaerobic zone 1, the construction investment building second pond 5 mud pump house can be saved thus, counteract the construction cost increasing capacity regulating pump 9 and increase to a certain extent.
