Working principle：

Sewage in cesspool enters thin filtering ponds by water inlet pipe, so that the large granular impurity in sewage be got rid of, passes through The sewage of filtering enters in anaerobic pond 1, the anaerobic bacteria in anaerobic pond 1 by hydrolysis stage, acidification stage and methanation stage from And the organic matter in waste water is removed, subsequently into anoxic pond 2, to carry out denitrification denitrogenation reaction；Then sewage enters Aerobic tank 3 allows activated sludge to carry out aerobic respiration, organic matter is further resolved into inorganic matter, then sewage enters first In membrane cisterna 4, sewage is further purified by the effect of filter membrane, then enters back into anaerobic pond 5, aerobic tank 6 and the second membrane cisterna 7, to realize the comprehensive decontamination of discharge sewage, purified sewage is discharged from outlet pipe 8, by filter membrane in the first membrane cisterna 4 There are many sewage sludge obstructed, and the purification for carrying out pollutant again is flowed back into anoxic pond 2 by return pipe；

For sewage after flowing into thin filtering ponds, thin filtering ponds are vertical filter pipe, are rotatablely connected filter screen 9, institute in pipeline The upper end for the filter screen 9 stated is connected to back purge system, and downside connects sewage pipe, is connected with electricity between sewage pipe and thin filter pipe The entrance of dynamic butterfly 10, back purge system is arranged in filter pipe inner wall, and the entrance of back purge system was provided with Mount board 11 is filtered, filter device plate 11 is quarter circular arc, and this structure can reduce the dirt being attached to above to the greatest extent, because For under the impact of gravity and top water flow, dirt more in lower section is easier to be flushed away, and the outlet of back purge system faces Open device 12 is connected to vertical pipeline 13 below open device 12, and vertical pipeline 13 is socketed in vertical tube 14,13 bottom of vertical pipeline The side at end is provided with water outlet 15, and the lower edge of water outlet 15 is close to the first sealing ring 16 of connection, the top connection of water outlet 15 There is the second sealing ring 17, the first sealing ring 16 and the second sealing ring 17 are between vertical pipeline 13 and vertical tube 14,14 He of vertical tube The corresponding position of water outlet 15 is provided with apopore 18, and one end of the connection water outlet inclined tube 19 of apopore 18 is discharged inclined tube 19 The other end is connected to filter pipe, is provided with motor-driven valve on the filter pipe of 11 top of filter device plate, described is vertical One end of hold-down bars 20 and spring 21 is fixedly connected with immediately below pipeline 13, the other end of the spring 21 is fixed on vertical tube 14 Bottom, the middle of the bottom of the vertical tube 14 is provided with switch 22, the switch 22 and motor-driven valve and electronic rotation is kept off Plate 10 is electrically connected, and the hold-down bars 20 is metal bar, and the switch 22 is made of electromagnet, in open device 12 Water is more and more, and gravity is increasing, and then compressed spring 21, when hold-down bars 20 and the contact of switch 22, on the one hand controls at this time Motor-driven valve above filter pipe processed is closed, and is entering water not, meanwhile, filter screen 9 inverts, and controls electronic rotation baffle 10 rotations, so that sewage pipe is connected to, switch 22 is also a kind of electromagnet, and hold-down bars 20 is metal bar, to generate attraction, is allowed Water in vertical pipeline is lasting by water outlet 15 and the outflow of apopore 18, and when water flow is complete, spring force is greater than electricity at this time Magnetic pull, hold-down bars rise, and switch disconnects power supply, while being lost magnetic force, restore to the original state, and 10 turns of electronic rotation baffle Dynamic, sewage pipe is closed；

Filter device plate is followed successively by immobilized microorganism layer 23, pharmacy particle layer 24 and filter membrane 25 from outside to inside, mainly can It is enough that sewage is subjected to adsorption filtration disinfection and is refiltered, keep sewage purification more thorough；It is interspersed among filter device plate to be connected with Phenomena such as fixing skeleton, filter device plate avoided to produce fracture by Sewage shock.

It is described above；It is merely preferred embodiments of the present invention；But scope of protection of the present invention is not limited thereto； Anyone skilled in the art is in the technical scope disclosed by the present invention；According to the technique and scheme of the present invention and its It improves design and is subject to equivalent substitution or change；It should be covered by the scope of protection of the present invention.
