Description
Technical field
The present invention relates to a kind of sewage disposal system, particularly relate to a kind of sewage-treatment plant.
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 processing method, 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 sewage-treatment plant, be applicable to small towns sanitary sewage disposal.
To achieve these goals, technical scheme of the present invention is as follows: a kind of sewage-treatment plant, is characterized in that: comprise 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 delivery port in grid pond is connected with the water inlet of regulating reservoir, the delivery port 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 delivery port of described sand filter distribution reservoir connects with multiple manpower rapid-infiltration pond, and the water outlet in described manpower rapid-infiltration pond drains into reuse pool; 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 basin,
The described mud of backwash sedimentation basin and the mud of regulating reservoir are extracted into sludge drying pond by sludge pump, described sludge drying pond comprises sludge drying pond body, longitudinal baffle is set in the body of described sludge drying pond and described sludge drying pond body is divided into two chambers in left and right, about this, the top of two chambers is respectively equipped with mud import, the mud import of left and right chamber is connected with the sludge pump in regulating reservoir with backwash sedimentation basin respectively, the bottom of described left and right chamber distinguishes horizontally set permeable geotechnique layer of cloth from top to bottom, gravel layer and double-edged fine-toothed comb, described double-edged fine-toothed comb is arranged by some bars longitudes and latitudes and forms, its aperture is less than 3mm, distance is had between the base plate of described double-edged fine-toothed comb and sludge drying pond body, the lower end of the left and right chamber of described sludge drying pond body is respectively equipped with discharge outlet, this discharge outlet is positioned at the below of double-edged fine-toothed comb, this discharge outlet is connected with regulating reservoir by pipeline, awning is provided with above the body of described sludge drying pond.
In such scheme, grid pond is mainly used in the preliminary removal to foreign material thick in water after sewage network accesses sewage treatment plant.Regulating reservoir, according to the actual conditions of the sewage water yield, ensures 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 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.
Mud enters the nature mummification of sludge drying pond, and the mud outward transport after mummification is disposed.
Sludge drying pond is divided into two chambers, and the mud at two places is separated mummification, better separately utilizes so that follow-up.Natural mummification on permeable geotechnique layer of cloth, slag wherein, successively through gravel and double-edged fine-toothed comb, stops by filtrate, and filtrate returns the regulating reservoir of manual controlled infusion, and sludge drying is effective, and structure is simple, and cost is low.
Sewage disposal system 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 double-edged fine-toothed comb is made up of batten or bamboo cane.Cost is low.
In such scheme: described discharge outlet arranges drainpipe, this drainpipe is layered on the base plate of sludge drying pond body, and this drainpipe arranges inlet opening.
Beneficial effect: structure of the present invention is simple, arranges that easily floor space is little, and construction cost is low, and operating cost is low, and treatment effect is good.
