6) adopt the mode of PLC controller technology and the pipeline that is crisscross arranged at the membrane module two ends, can wash by rubbing with the hands the membrane module surface fully, the dirt that is adsorbed on the membrane module surface comes off thereupon, and membrane flux is recovered, and filth-discharging effect is better.
Description of drawings
Fig. 1 is structural representation of the present utility model
Embodiment
As shown in Figure 1, sanitary sewage disposal of the present invention and retrieving arrangement comprise sewage settling bowl, oxidation pond, PLC controller, integral type MBR reactor, gas blower and vacuum pump.
Integral type MBR reactor places in the oxidation pond, and its built-in membrane module is simplicity of illustration, and MBR reactor and membrane module thereof do not illustrate; Gas blower enters oxidation pond inside by pipeline, and pipeline is crisscross arranged at the two ends of membrane module; Water after membrane module filters is discharged by vacuum pump; Integral type MBR reactor, gas blower and vacuum pump are controlled by the PLC controller.
The pipeline that is communicated with between oxidation pond and the sewage settling bowl is provided with the gulf (not shown) that is filled with water, and is used for stoping the gas that produces in the oxidation pond to turn back to the sewage settling bowl, avoids irritant gas such as ammonia to escape.
The central authorities of oxidation pond also are provided with pipeline, and like this, the mud of precipitation is returned in the sewage settling bowl by the mode of gas lift in the oxidation pond;
