Description
Technical Field
The utility model belongs to the sewage treatment device field, concretely relates to utilize unnecessary power to realize that integration equipment mixes device of liquid backward flow.
Background
With the development of economic society of China, water resource crisis and water environment pollution are increasingly aggravated, the discharge amount of various sewage and wastewater is greatly increased, the water environment is seriously endangered, and the treatment of water pollution becomes one of the focuses of attention in the field of domestic and foreign environmental protection. The treatment mode of sewage is divided into a town centralized treatment mode and a rural decentralized treatment mode, wherein the rural sewage adopts the decentralized treatment mode, and the integrated sewage treatment device is more suitable for the characteristics of rural sewage treatment in a flexible, simple and efficient decentralized treatment mode.
At present, the mode of pump is adopted in the mud backward flow of prior art, and the pump improves mud, then flows back to the front end, and the structure of pump is counted more complicacy by: motor, pump seat, impeller, pump shaft, mechanical seal constitute. In daily use, due to different contents of sludge and corrosiveness, a mechanical sealing element is often corroded, and water leakage of a pump is caused; secondly because the pump is often blocked up to the particulate matter is more in the mud, the clearance pump is not only wasted time and energy, and the operation is inconvenient, still influences equipment operation.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides an utilize unnecessary power to realize that integration equipment mixes device of liquid backward flow, it is easy and simple to handle, mud backward flow is efficient, avoids adopting traditional sludge pump and causes the phenomenon of jam.
The utility model discloses a realize through following technical scheme: the utility model provides an utilize unnecessary power to realize device of mixed liquid backward flow of integration equipment, includes a jar body, sets up at internal equalizing basin, air stripping device and good oxygen pond of jar and sets up the membrane bioreactor in good oxygen pond, equalizing basin one side intercommunication has the backflow pipeline, the current retarder is installed to the play water end of backflow pipeline, backflow pipeline intake end with the air stripping device is linked together, the well lower part of air stripping device pass through the air supply line with good oxygen pond intercommunication, be equipped with the aeration machine in the good oxygen pond, the air supply line is equipped with the valve in order to control air supply line atmospheric pressure.
Further, the current damper is horn-shaped.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses the design of jar internal air stripping device that sets up, the area that provides through the aeration machine in the good oxygen pond presses the air, realizes mixing the liquid backward flow, need not to increase power consumptive equipment such as conventional pumps, and investment cost is low, and does not have movable part in the operation process, and operation maintenance is simple.
2. The utility model discloses install the current retarder at return line's play water end, can reduce the disturbance effect to liquid in the regulation pond of backward flow liquid, guaranteed activated sludge's structurality.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the drawings: 1. a tank body; 2. a regulating tank; 3. a return line; 4. a flow damper; 5. a gas stripping device; 6. a gas supply duct; 7. a valve; 8. an aerobic tank; 9. a membrane bioreactor; 10. an aerator.
Detailed Description
The device for realizing the backflow of the mixed liquid of the integrated equipment by using the redundant power as shown in figure 1 in the attached drawing of the specification comprises a tank body 1, an adjusting tank 2, an air lifting device 5, an aerobic tank 8 and a membrane bioreactor 9 arranged in the aerobic tank 8, wherein the adjusting tank 2 is communicated with a backflow pipeline 3 at one side, a flow damper 4 is arranged at the water outlet end of the backflow pipeline 3, the water inlet end of the backflow pipeline 3 is communicated with the air lifting device 5, the middle lower part of the air lifting device 5 is communicated with the aerobic tank 8 through an air supply pipeline 6, an aerator 10 is arranged in the aerobic tank 8, and the air supply pipeline 6 is provided with a valve 7 for controlling the air pressure of the air supply pipeline 6.
The flow damper 4 is horn-shaped.
Pressurized air provided by an aerator 10 in an aerobic pool 8 enters the middle lower part of the air lifting device 5 through an air supply pipeline 6, so that a gas-liquid mixture with density smaller than that of mixed liquid outside the air lifting device 5 is formed in the air lifting device 5, the liquid level of the gas-liquid mixture with small relative density is higher than that of the mixed liquid outside the air lifting device 5 according to the liquid balance principle, and the mixed liquid outside the air lifting device 5 continuously flows from the bottom of the air lifting device 5 under the combined action of suction force formed by rising of the gas-liquid mixture in the air lifting device 5 and the pressure of the mixed liquid outside the air lifting device 5, so that reflux is realized; the horn-shaped flow damper 4 can reduce the disturbance effect of the reflux on the liquid in the regulating tank, and the structural property of the activated sludge is ensured.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
