Abstract
The utility model relates to a biochemical aeration treatment system using an activated sludge method, which includes a plurality of aeration tanks connected from front to back in series; the first aeration tank is provided with a sewage inlet; the last aeration tank is connected with two sedimentation tanks through pipelines; and aerators are arranged in the aeration tanks. The biochemical aeration treatment system is characterized in that the number of the aerators from the first aeration tank to the last aeration tank is reduced in sequence. With the biochemical aeration treatment system, the aeration volume can be adjusted through the decreasing number of the aerators, so that the alternation of the oxygen volume needed by the biochemical system can be satisfied, on one hand, the increasing energy consumption caused by excessive aeration can be avoided, the aeration cost is saved, the sewage treatment cost is reduced, and the better effect on the aspects of normal running and energy saving for sewage treatment can be achieved, but also the number of the aerators can be controlled directly to adjust the aeration volume without adjusting the openness of the valves of the aerators, the damage rate of the aerators can be reduced, and the service life of the aerators can be prolonged.
Description
Technical field
The utility model relates to the biochemical aeration treatment system of a kind of activated sludge process.
Background technology
The biochemical workshop of Shandong Lanxing Dongda Chemical Co.,Ltd is the matching construction of 60,000 tons of/year propylene oxide units, adopts conventional activated sludge process to carry out aerobic treatment to waste water.What biochemical aeration tank adopted is that a plurality of little aeration tanks are composed in series the big aeration treatment system of a cover, waste water is from first little aeration tank water inlet, enter second pond from last little aeration tank outflow and carry out mud-water separation, it is higher to pollute organism when waste water enters first little aeration tank, oxygen-consumption is big, the organism of handling along with aeration that pollutes reduces gradually, and oxygen-consumption also reduces gradually.And the aeration tank tends to install the aerator of equal amts from start to finish in the existing biochemical aeration treatment system, adjust aeration rate by the aperture of adjusting valve, excessive aeration appears in the little aeration tank of back so on the one hand easily, the big power consumption of aeration rate is high, cause the waste of the energy, unsuitable economically, as also can to reduce aerator on the other hand work-ing life.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of biochemical aeration treatment system of activated sludge process that can avoid excessive aeration, minimizing aeration expense, reduce cost of sewage disposal is provided.
The technical scheme that its technical problem that solves the utility model adopts is: the biochemical aeration treatment system of a kind of activated sludge process, comprise placed in-line from front to back a plurality of aeration tanks, first aeration tank is provided with into waste water mouth, last aeration tank connects second pond by pipeline, aerator is set in the aeration tank, it is characterized in that: the aerator quantity from first aeration tank to a last aeration tank reduces in turn.
In the biochemical aeration treatment system of activated sludge process, because the organic content height in first aeration tank, the oxygen requirement of microorganism is big, therefore need to install plurality purpose aerator, but along with organic content in the system reduces gradually, the oxygen requirement of microorganism also reduces gradually, therefore adjust the variation that aeration rate satisfies the biochemical system oxygen requirement by the quantity of aerator decrescence, promptly adjust the aeration rate of different steps by different aerator quantity, allow aeration rate and aerobic variation adapt, the energy consumption that can avoid excessive aeration to cause increases, save the aeration expense, reduce cost of sewage disposal simultaneously, and obtaining effect preferably aspect the normal operation of sewage disposal and the energy conservation.In addition, need not adjust the aperture of aerator valve and directly regulate aeration rate, therefore can reduce the spoilage of aerator, prolong the work-ing life of aerator by control aerator quantity.
The beneficial effect that the utility model had is: provide a kind of activated sludge process biochemical aeration treatment system, can pass through the decrescence quantity adjustment aeration rate of aerator, thereby satisfy the variation of biochemical system oxygen requirement, the energy consumption that can avoid excessive aeration to cause on the one hand increases, save the aeration expense, reduce cost of sewage disposal, obtaining effect preferably aspect the normal operation of sewage disposal and the energy conservation, need not adjust the aperture of aerator valve on the other hand and directly regulate aeration rate by control aerator quantity, can reduce the spoilage of aerator, prolong the work-ing life of aerator.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of aeration tank among Fig. 1.
Among the figure: 1, advance the waste water mouth; 2, aeration tank; 3, pipeline; 4, second pond; 5, aerator
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, 2, the biochemical aeration treatment system of activated sludge process comprises placed in-line from front to back a plurality of aeration tank 2, first aeration tank is provided with into waste water mouth 1, last aeration tank connects second pond 4 by pipeline 3, aerator 5 is set in the aeration tank 2, it is characterized in that: aerator 5 quantity from first aeration tank to a last aeration tank reduce in turn.
In the biochemical aeration treatment system of activated sludge process, because the organic content height in first aeration tank, the oxygen requirement of microorganism is big, therefore need to install plurality purpose aerator, but along with organic content in the system reduces gradually, the oxygen requirement of microorganism also reduces gradually, therefore adjust the variation that aeration rate satisfies the biochemical system oxygen requirement by the quantity of aerator decrescence, promptly adjust the aeration rate of different steps by different aerator quantity, allow aeration rate and aerobic variation adapt, the energy consumption that can avoid excessive aeration to cause increases, save the aeration expense, reduce cost of sewage disposal simultaneously, and obtaining effect preferably aspect the normal operation of sewage disposal and the energy conservation.In addition, need not adjust the aperture of aerator valve and directly regulate aeration rate, therefore can reduce the spoilage of aerator, prolong the work-ing life of aerator by control aerator quantity.
