Description
Technical field
The present invention relates to a kind of Sewage treatment systems, particularly relate to a kind of field town domestic sewage processing system.
Background technology
Along with the enhancing of people's environmental consciousness, sewage disposal has become the Important Problems that national governments pay close attention to, China's sewage source mainly contains three, and the sewage produced in residents from villages and towns district dispersant type domestic wastewater, the centralized sanitary sewage in urban life district and Industrial processes.Utilize that to carry out purification to sewage in sandy soil be traditional wastewater treatment process, there are some shortcomings in existing this sewage water treatment method, the removal ability of TN and TP is lower, also needs to place the biochemical treatment tanks such as some denitrification ponds.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides another kind of field town domestic sewage processing system, be applicable to small towns sanitary sewage disposal.
To achieve these goals, technical scheme of the present invention is as follows: a kind of field town domestic sewage processing system, is characterized in that: comprise grating tank, equalizing tank, sand filter, sand filter distribution reservoir, manpower rapid-infiltration pond and reuse pool; Sanitary sewage enters described grating tank, the water outlet of described grating tank is connected with the water-in of equalizing tank, the water outlet of described equalizing tank is connected with the water-in of sand filter, liquid in described sand filter is discharged to sand filter distribution reservoir from bottom liquid outlet, the water outlet of described sand filter distribution reservoir connects with four manpower rapid-infiltration ponds, and the water outlet in described manpower rapid-infiltration pond drains into reuse pool.
In such scheme, grating tank is mainly used in the preliminary removal to foreign material thick in water after sewage network accesses sewage work.Equalizing tank, according to the practical situation of the sewage water yield, ensures that the normal table of sewage work's production facility runs, plays the effect of precipitation and homogeneous even amount.Sand filter major function removes micro-impurities further, and ensure the normal operation of oozing pond soon, the major function of sand filter distribution reservoir is the uniform water distribution realizing manpower rapid-infiltration pond.Reuse pool is mainly used in backwash water, and the double sterilization pool that does is used simultaneously.
Sewage treatment systems of the present invention, influent quality is as follows:
| Project | COD(mg/L) | BOD5(mg/L) | SS(mg/L) | TN(mg/L) | NH3-N(mg/L) | TP(mg/L) |
| Water quality | 350 | 150 | 230 | 35 | 25 | 4.0 |
Effluent quality is:
| Project | COD(mg/L) | BOD5(mg/L) | SS(mg/L) | TN(mg/L) | NH3-N(mg/L) | TP(mg/L) |
| Water quality | ≤60 | ≤20 | ≤20 | ≤20 | ≤8 | ≤1 |
The contrast of above-mentioned two tables can be found out, this system architecture is simple, arranges that easily treatment effect is good.
In such scheme: described reuse pool is connected with the back flushing inlet channel of sand filter by pipeline, the back flushing rising pipe of described sand filter is connected to backwash settling tank.The described mud of backwash settling tank and the mud of equalizing tank enter sludge drying pond.Mud enters the nature mummification of sludge drying pond, and the mud outward transport after mummification is disposed.
Beneficial effect: structure of the present invention is simple, arranges that easily floor space is little, and construction cost is low, and running cost is low, and treatment effect is good.
Accompanying drawing explanation
Fig. 1 is schema of the present utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Fig. 3 is the sectional view of manpower rapid-infiltration pond CRI-1 type packing layer, CRI-2 type packing layer and manpower rapid-infiltration gravel padding layer.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
The present invention waits the relative position of the noun of locality only in representative graph all around, does not represent the absolute location of product.
