And rural sewage treatment generally adopts a/O or improved a/O, the activated sludge and nitrifying liquid in the conventionally buried integrated a/O sewage treatment apparatus have mainly depended on the pump to reflow. The submersible sewage pump is inconvenient to install and maintain and has high energy consumption. Therefore, the utility model adopts the air stripping reflux device to carry out the sludge reflux and the nitration liquid reflux in consideration of the rural economic condition and the maintenance and management of the equipment.
Disclosure of Invention
An object of the utility model is to provide a bury formula mud and nitrify liquid air lift backward flow sewage device, the utility model discloses the device adopts air lift mode backward flow mud or nitrify liquid, only needs compression fan to provide partial amount of wind, can reach the purpose of mixing liquid backward flow, has saved the electric energy.
The utility model aims at realizing through the following technical scheme:
a buried sewage device for gas lift and return of sludge and nitrified liquid comprises an air supply pipe, a liquid lifting pipe, a gas-liquid separation box, a return pipe and a suction port, wherein the air supply pipe is introduced into the liquid lifting pipe from the lower part, the gas-liquid separation box is arranged at the upper part of the liquid lifting pipe, and the gas-liquid separation box is communicated with the return pipe; one end of the air supply pipe is connected with the aeration compression fan, and the other end of the air supply pipe is connected with the riser pipe connector.
The buried sludge and nitrified liquid gas-lift backflow sewage device is characterized in that a liquid lifting pipe connecting port is located 10cm above a suction port.
A bury formula mud and nitrify liquid gas and carry backward flow sewage device, the stalk lower extreme is the loudspeaker suction inlet, loudspeaker suction inlet angle is 15~30 degrees.
The buried sludge and nitrified liquid gas-lift backflow sewage device is characterized in that the top of the liquid lifting pipe is connected with the gas-liquid separation box and needs to be higher than the backflow pipe.
The buried sludge and nitrified liquid gas-lift backflow sewage device is characterized in that the bottom of the gas-liquid separation tank horizontally inclines downwards, the inclination angle is 15 degrees, and the inclination angle of the backflow pipe is 15 degrees.
The utility model has the advantages and effects that:
1. the utility model discloses can not destroy the mud floc, it is very favourable to the activity and the settleability that maintain mud, and no matter be mud backward flow or nitrify the liquid backward flow, the volume of the mixed liquid of backward flow all is very huge, the utility model discloses the device has cancelled the mud backwash pump in the traditional sedimentation tank, if adopts the tradition to return with the pump, will consume very big electric energy, adopts air stripping method backward flow mud or nitrify the liquid, only needs compression fan to provide a little less part amount of wind, can reach the purpose of mixed liquid backward flow, very big saving the electric energy, this device adopts air stripping device backward flow to mix the liquid and has fine economic benefits.
