Interior middle part, the bottom of vertical tube 10 are provided with the water-locator 6 connected with the bottom of filtrate storehouse 7, filtrate are set with the vertical tube 10
Suction channel 9, the lower section of filtrate suction channel 9 is extended at the bottom of filtrate storehouse 7 through water-locator 6 is provided with pulsed lifting
Pump 11, the air inlet pipe 14 are connected with pulsed elevator pump 11, and filtrate washer 12 is provided with the top of the filtrate suction channel,
The cleaning water inlet 4 and rinse water sewage draining exit connected with filtrate washer 12 is provided with the body 1, on filtrate washer 12
It is provided with the filtrate outlet 13 of the top of filtrate storehouse 7 connection.
The present embodiment is based on countercurrent action, and pending sewage is through water inlet 2, water inlet pipe 5 and vertical tube 10, by positioned at device
The water-locator 6 of body bottom enters in filtrate storehouse 7, and current flow up through filtrate 8, and filtrate 8 slowly moves down；In the process,
Raw water is filtered, and the pollutant load in water reduces, and the clear water after filtering is assembled at the top of body, flowed out through delivery port 3；
Pollutant load increase in filtrate simultaneously, and the pollutant load of lower floor's filtrate is higher than upper strata filtrate；It is now placed in filter
The pulsed elevator pump 11 in center is formed in the presence of bubble in air inlet pipe continuous gas entry, interval, and lower floor's filtrate is passed through into filtrate
Suction channel is promoted in the filtrate washer 12 at the top of body, pollutant is separated from filtrate 8 by action of turbulent flow simultaneously outer
Row, the filtrate after cleaning is returned in filtrate storehouse 7 using deadweight to be reused.
Further, the pulsed elevator pump includes the pump housing 15, and the atmosphere chamber of bottom opening is provided with the pump housing 15
16th, atmosphere chamber 16 and open-topped small air cavity 17 are sleeved on, the small air cavity 17 is connected by open top with atmosphere chamber 16,
The air inlet pipe 14 is connected to the top of the pump housing 15 and connected with atmosphere chamber 16 and small air cavity 17, and the filtrate suction channel 9 is simultaneously
It is sleeved in atmosphere chamber 17 and small air cavity 16, the bottom of filtrate suction channel 9, which is extended in the small setting of air cavity 17, material sucking port,
The air admission hole 19 for connecting small air cavity is provided with the tube wall that the filtrate suction channel 9 is located in small air cavity 17.
The present embodiment is closed by being provided with small one and large one two air cavitys, two air cavitys in the pump housing by open at one end one end
