Adopt after technique scheme, the utlity model has following positive effect:
(1) the utility model sewage-treatment plant has additional backwash suction hose on outlet pipe, can use the sewage being extracted in outlet pipe oppositely to enter sedimentation basin inside, and by backwash suction hose a plurality of shower nozzles around, under water spray pressure, wash away and stir periphery mud, thereby after being mixed, mud and sewage siphoned away by sewage pump, thereby reduced the accumulation of mud in sedimentation basin, improved the service life of sewage pump and the extraction efficiency of sewage; And adopt the sewage of extracting out to carry out backwash, without adopting clear water or compressed air to wash away mud, avoided water resource, compressed-air actuated waste, save the energy and be simple and easy to and install;
(2) on the utility model backwash suction hose, be also provided with the valve of turning one's coat, can conveniently control the backwash time, thereby can carry out backwash according to the actual accumulation situation of mud, can reach the object of timely flushing, also can be when mud need to rinse valve-off, reach energy-saving consumption-reducing object;
(3) the utility model water inlet pipe lower end is horn opening, can raising and the contact area of mud and sewage, thus improve the extraction efficiency of mud and sewage; And the length of shower nozzle is long and horn mouth length, further strengthened the mixing effect of bottom mud;
(4) the utility model backwash suction hose specification can be selected according to actual conditions, thereby meets the diversified demand in producing;
(5) the utility model simple in structure, design ingenious, easy to operately, improvement cost is low, can be widely used in the sewage disposal that contains more deposition immobilized particles in each field.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the utility model structural representation;
In figure 1, sewage pump; 2, outlet pipe; 3, water inlet pipe; 31, horn mouth; 4, backwash suction hose; 41, the valve of turning one's coat; 5, shower nozzle; 6, sedimentation basin.
