As shown in Figure 1-Figure 3, a kind of rural domestic sewage treatment system, including processing pond, the processing pond include level-one
Processing pond 1, two stage treatment pond 2 and tertiary treatment pond 3, coagulation pond 1 are equipped with solids and intercept cover 4, and it is logical that solids intercepts cover 4
It crosses fixed link 15 to be fixed at 1 Chi Kou of coagulation pond, solids intercepts and is evenly distributed with scupper 41, coagulation on cover 4
Solids collecting tank 5 and Water warfare plate 6 are connected on 1 side wall of pond, the quantity of Water warfare plate 6 is two or more, and Water warfare plate 6 inclines
Tiltedly setting, for adjacent Water warfare plate 6 in being arranged in a zigzag and not connecting between each other, 6 top of Water warfare plate is equipped with filter layer 7, water
It is equipped with filter hole 61 inside purifying board 6, is further connected with outlet pipe I8 on 1 lower sides of coagulation pond, outlet pipe I8 is another
One end connects two stage treatment pond 2, is successively arranged PP cotton filtering meshes 9, seed activity layer of charcoal 10 from top to bottom in two stage treatment pond 2
With extruded activated carbon layer 11, further connected with outlet pipe II12 on 2 lower sides of two stage treatment pond, outlet pipe II12's is another
End connection tertiary treatment pond 3, tertiary treatment pond 3 is interior to be equipped with reverse osmosis membrane 13.
The technical solution that the present invention advanced optimizes, it is in mitriform that the solids, which intercepts cover 4,.
The technical solution that the present invention advanced optimizes, the solids intercept cover 4 and are connected by connector and fixed link 15,
Solids, which intercepts, is less than 2cm to the distance between 1 side wall of coagulation pond at 4 lower openings of cover, and solids, which intercepts cover 4, to be enclosed
It is all around swung in coagulation pond 1 around fixed link 15.
The technical solution that the present invention advanced optimizes, one end of the Water warfare plate 6 are connected to 5 lower part of solids collecting tank
1 side wall of coagulation pond on, the length of Water warfare plate 6 is less than the length inside coagulation pond 1.
The technical solution that the present invention advanced optimizes, the quantity of Water warfare plate 6 are four.
The technical solution that the present invention advanced optimizes, the filter layer 7 be asphalt felt or oil absorbent material or granular activated carbon or
At least one of extruded activated carbon.
The two sides of the technical solution that the present invention advanced optimizes, the Water warfare plate 6 are equipped with baffle 62.
The technical solution that the present invention advanced optimizes, the solids collecting tank 5 are equipped with through-hole 51.
The technical solution that the present invention advanced optimizes, the outlet pipe II12 are equipped with pressure pump 14, the reverse osmosis membrane
13 divide in tertiary treatment pond 3 for water purifying tank 31 and waste liquid pool 32, are respectively equipped with water outlet 33 on water purifying tank 31 and waste liquid pool 32.
Whole work process of the invention is as follows: after domestic sewage in rural areas enters coagulation pond 1 by intake tunnel, Gu
Body rubbish or bulky grain waste can intercept cover 4 by solids and intercept, and water flow is intercepted on cover 4 by solids scupper 41
Outflow, when solid refuse gathers to a certain extent, solids intercepts 4 meeting disequilibrium of cover, the more side meeting of garbage weight
Under turn over, since solids collecting tank 5 intercepts under cover 4 in the scope of activities turned in solids, solid refuse can be dumped into
Enter solids collecting tank 5, solids intercepts cover 4 and is gradually recovered balance；
Solids collecting tank 5 is equipped with through-hole 51 and prevents for further filtering the sewage remained between solid refuse
Solid refuse due to sewage presence and ferment and then generate foul odour, in addition, solids, which intercepts cover 4, can also play and prevent from disliking
The effect that foul smell taste disseminates, prevents fly from breeding；By through-hole 51 and solids intercept sewage that the scupper 41 on cover 4 flows out into
One step flows on Water warfare plate 6, and 6 top of Water warfare plate is equipped with filter layer 7, and filter layer 7 is that asphalt felt or oil absorbent material or particle are living
Property at least one of charcoal or extruded activated carbon, zeolite, since adjacent Water warfare plate 6 is in setting in a zigzag and not phase between each other
It connects, therefore while filter layer 7 filters, water body further toward flowing down, successively passes through upper and lower four Water warfare plates 6, therefore can be with
Play the role of being filtered for multiple times, further enhances filter effect；
Last water body flows into two stage treatment pond 2 by outlet pipe I8, using PP cotton filtering meshes 9, granular activated carbon
The filtration treatment of layer 10 and extruded activated carbon layer 1, flows into tertiary treatment pond 3 again by outlet pipe II12, and during which water body passes through
After pressure pump 14 pressurizes, stage purification is carried out by reverse osmosis membrane 13, the water body in last water purifying tank 31 can satisfy daily life
It needs, the water in waste liquid pool 32 can satisfy the needs such as field irrigation.
It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it is still
It is possible to modify the technical solutions described in the foregoing embodiments, or some or all of the technical features is carried out
Equivalent replacement；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution various embodiments of the present invention technical side
The range of case.
