Description

Manpower rapid-infiltration domestic sewage processing system

Technical field

This utility model relates to a kind of sewage disposal system, particularly relates to a kind of manpower rapid-infiltration domestic sewage processing system.

Background technology

Enhancing along with people's environmental consciousness, sewage disposal has become as the Important Problems that national governments pay close attention to, China's sewage source mainly has 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. Utilizing that sewage carries out in sandy soil purification is traditional wastewater processing method, existing this sewage water treatment method there are disadvantages that, the removal ability of TN and TP is relatively low, in addition it is also necessary to places the biochemical treatment tanks such as some denitrification ponds.

Utility model content

In order to solve above-mentioned technical problem, this utility model provides another kind of manpower rapid-infiltration domestic sewage processing system, is suitable for small towns sanitary sewage disposal.

To achieve these goals, the technical solution of the utility model is as follows: a kind of manpower rapid-infiltration domestic sewage processing system, it is characterised in that: include grid pond, regulating reservoir, sand filter, sand filter distribution reservoir, manpower rapid-infiltration pond and reuse pool; Sanitary sewage enters described grid pond, the described outlet in grid pond is connected with the water inlet of regulating reservoir, the outlet of described regulating reservoir is connected with the water inlet of sand filter, liquid in described sand filter is discharged to sand filter distribution reservoir from bottom liquid outlet, the outlet of described sand filter distribution reservoir connects with multiple manpower rapid-infiltration ponds, and the water outlet in described manpower rapid-infiltration pond drains into reuse pool.

In such scheme, grid pond is mainly used in the preliminary removal after sewage network accesses sewage treatment plant to foreign material thick in water. The regulating reservoir practical situation according to the sewage water yield, it is ensured that the normal table of sewage treatment plant's production facility runs, plays the effect of precipitation and homogeneous even amount. Sand filter major function is to remove micro-impurities further, it is ensured that ooze the properly functioning of pond soon, and the major function of sand filter distribution reservoir is to realize the uniform water distribution in manpower rapid-infiltration pond. Reuse pool is mainly used in backwash water, also serves as sterilization pool simultaneously and uses.

Sewage disposal system of the present utility model, 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

≤8

≤1

The contrast of above-mentioned two table, it can be seen that this system structure is simple, is arranged easily, high treating effect.

In such scheme: described reuse pool is connected with the backwash inlet channel of sand filter by pipeline, and the backwash outlet pipe of described sand filter is connected to backwash sedimentation tank. The mud of described backwash sedimentation tank and the mud of regulating reservoir enter sludge drying pond. Mud enters the nature mummification of sludge drying pond, and the mud outward transport after mummification is disposed.

Beneficial effect: this utility model simple in construction, arranges that easily floor space is little, and construction cost is low, and operating cost is low, high treating effect.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

This utility model all around waits the relative position in the noun of locality only representative graph, does not indicate that the absolute position of product.

Embodiment 1, as Figure 1-3: manpower rapid-infiltration domestic sewage processing system of the present utility model is made up of parts such as grid pond 1, regulating reservoir 2, sand filter 3, sand filter distribution reservoir 4, manpower rapid-infiltration pond 5, reuse pool 6, backwash sedimentation tank 7, sludge drying pond 8, awnings 9.

Field town sanitary sewage enters grid pond 1 through pipe network, the outlet in grid pond 1 is connected with the water inlet of regulating reservoir 2, the outlet of regulating reservoir 2 is connected with the water inlet of sand filter 3, liquid in sand filter 3 is discharged to sand filter distribution reservoir 4 from bottom liquid outlet, the outlet of sand filter distribution reservoir 4 connects with multiple manpower rapid-infiltration ponds 5, selects four here. The water outlet in manpower rapid-infiltration pond 5 drains into reuse pool 6. Reuse pool 6 is connected with the backwash inlet channel 3a of sand filter 3 by pipeline, and the backwash outlet pipe 3b of sand filter 3 is connected to backwash sedimentation tank 7.
