Working principle：

Sewage in cesspool enters coarse filtration pond 1 by water inlet pipe, thus outside by the contaminant exclusion of bulky grain, then Sewage enters thin filtering ponds 2, so that the relatively fine particulate pollutant in sewage be excluded, then sewage enters anaerobic pond In 3, the anaerobic bacteria in anaerobic pond 3 removes the organic matter in waste water by hydrolysis stage, acidification stage and methanation stage, Subsequently into the first anoxic pond 4, to carry out denitrification denitrogenation reaction；Then sewage enters back into aerobic tank 5, allows active dirty Mud carry out aerobic respiration, organic matter is further resolved into inorganic matter, sewage enters in the second anoxic pond 6 later, again into The reaction of row denitrification denitrogenation, enters in membrane cisterna 7 later, is further purified sewage by the effect of filter membrane, purified water It is discharged by outlet pipe 8, while aerobic tank 5 is connected to by return pipe with the first anoxic pond 5, so that following repeatedly for sewage will be realized The carry out denitrification denitrogenation reaction of ring and allow activated sludge carry out aerobic respiration, so that the thorough purification of sewage is realized, in order to keep away Exempt from metallic particles or fines in sewage in membrane cisterna filter membrane and the present apparatus damage, so remote in coarse filtration pond 1 It is provided with alternating electromagnet on inner wall from thin filtering ponds 2, so as to which metal object is attracted, turn-off current, exchange Electromagnet loses magnetism, and metal object is fallen in metal holding box, thus the processing for the metal object concentrated；

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；

Dirt is attached in membrane cisterna 7 is provided on the first filter membrane 23 and the second filter membrane 24 for a long time in order to prevent, so It is provided with vibration device on first filter membrane 23 and the second filter membrane 24, when electromagnet indirect current, attracts each other, separate, from And realize the movement of the first filter membrane 23 and the second filter membrane 24, thus by the dirt removal of attachment, to realize raising filtering The filter efficiency of film.

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.
