Abstract
The invention provides a method for biological treatment of waste water. The method comprises a storage tank, a tray aerator, an aeration column, a gas inlet pipe, a gas outlet valve, a gas exhaust valve, a gas inlet valve, a blower, a probe, an oxygen content analyzer and a PLC, wherein the tray aerator is arranged at the bottom of the storage tank; a plurality of aeration columns are fixed to the upper part of the tray aerator; the aeration columns and the tray aerator have the same interiors; one side of the tray aerator is connected with the gas inlet pipe; the gas inlet pipe leads to the exterior of the storage tank; the gas inlet valve is arranged at a gas inlet end of the blower; the probe is arranged below a liquid level inside the storage tank; the probe is electrically connected with the oxygen content analyzer; the oxygen content analyzer is electrically connected with the PLC; the PLC is electrically connected with the blower. The invention has the benefits that a set of automatic control system is arranged inside the storage tank; when an oxygen content is reduced to a certain lower limit, the blower is turned on to oxygenate, so as to reduce the labor cost.
Description
Technical field
The present invention relates to sewage treatment equipment field, especially relate to a kind of biological treatment method for waste water.
Background technology
Biological tank flows to the discharge of sewage, organic pollutant composition and content always big ups and downs thereof, and thus in pond, the treating processes of sewage also always plays pendulum, thus causes the continuous change of relevant operating parameter and sewage effluents quality in biological tank.Time serious, microbe survival environmental degradation in biological tank, biochemical reaction is destroyed, and cause active sludge downright bad and float, produce sludge bulking phenomenon, biological tank loses sewage treatment capacity substantially, and effluent quality cannot reach emission standard.This is that sewage disposal institute is unallowed.As everyone knows, the microorganism mainly based on aerobic bacteria carrying out organic substance decomposing is participated in biological tank, its growing environment is got dirty the impact of water oxygen Gas content, if utilize aerating system to carry out aeration to sewage in biological tank, the existence of biological tank Microbial Communities in Activated Sludge and the oxygen needed for breeding are provided, just can ensure normally carrying out of biological tank biochemical reaction.
Invention
Technical scheme of the present invention is:
Biological treatment method for waste water, comprises storage tank, plate-type aerator, aeration post, inlet pipe, air outlet valve, vent valve, intake valve, gas blower, probe, oxygen content analyzer and PLC;
Described tank bottom is provided with described plate-type aerator, described plate-type aerator top is fixedly installed some described aeration posts, described aeration post is identical with described plate-type aerator inside, and the side of described plate-type aerator is connected with described inlet pipe, and the described in the same way storage tank of described inlet pipe is outside;
The inlet end of described gas blower is provided with described intake valve, and the outlet side of described gas blower is connected in parallel by pipeline and described vent valve, air outlet valve, and described air outlet valve is connected with described inlet pipe by pipeline;
Below the liquid level of described tank inside, be provided with described probe, described probe is electrically connected with described oxygen content analyzer, and described oxygen content analyzer is electrically connected with described PLC, and described PLC is electrically connected with described gas blower.
Further, described probe is equipped with buffering flow container.
Further, described vent valve, intake valve, air outlet valve are straight-through stop valve.
Further, the part that described inlet pipe passes described storage tank is provided with seal gum.
The advantage that the present invention has and positively effect are: owing to adopting technique scheme, this device has following characteristics:
1, be equipped with the probe of buffering flow container to rinse at any time, check and correction, ensures measuring accuracy.
2, the reason that straight-through stop valve elected as by vent valve, intake valve, air outlet valve is its good sealing effect, and cost is low, only relates to air again in this device, does not need the valve of more high standard.
3, the part that inlet pipe spreads out of storage tank is easily leaked, so arrange seal gum, reduces and reveals.
4, a set of automatic control system is set in tank inside, when the certain lower of oxygen level reduction is prescribed a time limit, opens gas blower, carry out oxygenation, decrease cost of labor.
5, plate-type aerator selected by oxygen replenishing equipment, can mate storage tank, then obtain larger contact area.

Embodiment
As shown in Figure 1, the present invention includes storage tank 1, plate-type aerator 3, aeration post 2, inlet pipe 4, air outlet valve 5, vent valve 8, intake valve 7, gas blower 6, probe 9, oxygen content analyzer 11 and PLC12;
Described plate-type aerator 3 is provided with bottom described storage tank 1, described plate-type aerator 3 top is fixedly installed some described aeration posts 2, described aeration post 2 is inner identical with described plate-type aerator 3, the side of described plate-type aerator 3 is connected with described inlet pipe 4, the described in the same way storage tank 1 of described inlet pipe 4 is outside, and the part that described inlet pipe 4 passes described storage tank 1 is provided with seal gum;
The inlet end of described gas blower 6 is provided with described intake valve 7, the outlet side of described gas blower 6 is connected in parallel by pipeline and described vent valve 8, air outlet valve 5, described air outlet valve 5 is connected with described inlet pipe 4 by pipeline, and described vent valve 8, intake valve 7, air outlet valve 5 are straight-through stop valve;
Described probe 9 is provided with below the liquid level of described storage tank 1 inside, described probe 9 is electrically connected with described oxygen content analyzer 11, described oxygen content analyzer 11 is electrically connected with described PLC12, and described PLC12 is electrically connected with described gas blower 6, and described probe 9 is equipped with buffering flow container.
The working process of this example: gas blower 6 constantly carries air in inlet pipe 4, plate-type aerator 3 is provided with bottom storage tank 1, air is discharged from aeration post 2, fully contact with water body, probe 9 is arranged in water body, and has oxygen content analyzer 11, sends signal to PLC12, PLC12 judges whether to continue to power to gas blower 6 according to signal, allows air continue to blast water body inside.
