Description
Technical field
The present invention relates to a kind of Sewage treatment systems, particularly relate to the Intellectualized sewage water treatment system in a kind of applicable field town.
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 the another kind of Intellectualized sewage water treatment system being applicable to field town, being applicable to small towns sanitary sewage disposal.
To achieve these goals, technical scheme of the present invention is as follows: the Intellectualized sewage water treatment system in a kind of applicable field town, is characterized in that: comprise grating tank, equalizing tank, sand filter, sand filter distribution reservoir, manpower rapid-infiltration pond and reuse pool;
The Buffer Pool that described grating tank is arranged side by side by front and back and grating tank body form, wherein grating tank body is positioned at rear side, the bottom of described Buffer Pool arranges water inlet pipe, the top of described Buffer Pool is provided with upflow tube, the bottom of the partition wall of described Buffer Pool and grating tank body arranges hand sluice valve, the bottom of described grating tank body arranges longitudinal grid, is provided with maintenance steel ladder in the grating tank body above the side of described grid;
Described grating tank body is communicated with equalizing tank, the preliminary sedimentation tank be arranged side by side about described equalizing tank comprises and even pond, described preliminary sedimentation tank is positioned at the right side of grating tank, the bottom of described preliminary sedimentation tank is provided with sludge pump, the front side of the partition wall between described preliminary sedimentation tank and even pond is provided with water stream channel, the bottom in described even pond is provided with lift pump, described sludge pump is near water stream channel, described lift pump is positioned at the position away from water stream channel, water level gauge is set in described even pond, the rising pipe of described lift pump arranges valve;
The rising pipe of described lift pump 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 multiple manpower rapid-infiltration pond, and the water outlet in described manpower rapid-infiltration pond drains into reuse pool;
Also comprise controller, the lift pump control end of described controller connects lift pump, and the Valve controlling end of described controller connects valve, water level signal is passed to controller by described water level gauge, when water level exceedes appointment water level, controller by-pass valve control is opened, and controls lift pump work simultaneously; When water level is lower than appointment water level, described controller by-pass valve control and lift pump are closed.
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.
Concrete: before grating tank, Buffer Pool is set, different local next sewage first here tentatively mixes, then grid is flowed through, after bulk sundries blocking, sewage enters the preliminary sedimentation tank of equalizing tank, preliminary sedimentation tank and even pond are separated, and channel setting is in the side away from grating tank, like this, make the flowing time of sewage in equalizing tank elongated, such one side makes the better effects if of sludge settling, makes the mixing of different sewage better on the other hand, makes the microorganism mixing carried in sewage evenly be conducive to follow-up process.Preliminary sedimentation tank and even pond are separated simultaneously, reduce the amount entering the mud of next step sand filter, reduce the processing pressure of sand filter.
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.
Last: by the closedown of water level gauge auto-controlled water-pumping pump, to realize intellectualized operation, when night, sanitary sewage was few, lift pump will stop automatically, need not need artificial closedown again, time saving and energy saving.
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.
In such scheme: the limit of the base plate in described preliminary sedimentation tank and even pond is equipped with a pit, described sludge pump and lift pump are arranged in pit.Be convenient to the extraction of mud and water.
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, by the opening and closing of water level gauge auto-controlled water-pumping pump, realizes intellectualized operation.
