Domain；The water hole for being connected to adjacent two-stage buffer area is opened up on the water retaining dikes at different levels, and guarantees the mistake on adjacent water retaining dike
Water hole is dislocatedly distributed along water retaining dike short transverse；
3) in the bottom of each buffer area, successively paving fills out rubble layer, soil horizon, aluminium modified soil layer from bottom to top, or certainly
Successively paving fills out aluminium modified soil layer, soil horizon, rubble layer on down；Guarantee the thickness of rubble layer, soil horizon, aluminium modified soil layer
It is respectively 10~20 ㎝；The aluminium modified soil layer is formed by aluminium modified clay and soil by 3:97 mixture, and the aluminium is modified
Clay is formed by clay, aluminum sulfate, the mountain flour that partial size is 1-3 ㎜ by the weight ratio mixture of 6:3:11.Aluminium modified clay mainly at
Divide and is shown in Table 1.
Table 1: aluminium modified clay main component (%)
| SiO2 | Al2O3 | Fe2O3 | MgO | CaO | Na2O | K2O | MnO | P2O5 | TiO2 | Loss |
| 26.41 | 8.40 | 0.89 | 1.64 | 26.90 | 1.82 | 0.77 | 0.01 | 0.04 | 0.10 | 33.02 |
Apparatus of the present invention include buffer pool and sedimentation basin；Buffering bottom of pond portion is hill-like structure, along gradient direction in the buffer pool
Several grades of water retaining dikes that buffer pool is divided into multiple buffer areas are distributed with；Have on water retaining dikes at different levels and delays the adjacent two-stage
The water hole of regional connectivity is rushed, the water hole on adjacent water retaining dike is dislocatedly distributed along water dike short transverse；The bottom of each buffer area
Successively paving is filled with rubble layer, soil horizon, aluminium modified soil layer from bottom to top in portion, or successively paving is filled with aluminium Modified soil from bottom to top
Earth layer, soil horizon, rubble layer；Sedimentation basin is connected to by aqueduct with first order buffer area, outlet pipe and most end first-level buffer
Regional connectivity.
Water hole in above-mentioned apparatus is arranged close to the top of water retaining dike or bottom；Aluminium modified soil layer in above-mentioned apparatus
It is formed by aluminium modified clay and soil mixture, the aluminium modified clay is by clay, aluminum sulfate, the mountain flour mixture that partial size is 1-3 ㎜
It forms；The thickness of rubble layer, aluminium modified soil layer, soil horizon in above-mentioned apparatus is respectively 10~20 ㎝.
Compared with the prior art, the present invention in loke shore buffer strip building bottom by adopting the above-described technical solution, have
The buffer pool is divided into multi-buffer region using water retaining dike by the buffer pool of the gradient, and buffer area middle berths at different levels fill out by
Aluminium modified soil layer made of clay, aluminum sulfate, mountain flour, soil mixture, therefore can be adsorbed by way of infiltration, intercept dirt
Phosphorus in water runoff, to reduce pollution of the agricultural area source to lake.It is arranged due to being equipped with high infraversion malposition on adjacent water retaining dike
Water hole, therefore residence time of the runoff in buffer pool can be extended to the maximum extent, make phosphorus therein by abundant absorption,
Dirt is cut, clean-up effect is improved.It is modified in aluminium in order to efficiently use the phosphorus in water body, increase soil fertility, reduction overall cost
The surface or the back side of soil horizon, which can also be spread, fills out one layer of sedentary soil layer.
It is demonstrated experimentally that using the method for the present invention and after device processing sewage 46 days, simulation rainwash 10 times, runoff simulation
In tp removal rate still up to 90% or more.As it can be seen that the method for the present invention and device can not only effectively cut down the pollution of agricultural area source phosphorus, and
And has many advantages, such as to handle duration length, cuts dirty effect stability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of apparatus of the present invention.
In figure: outlet pipe 1, water retaining dike 2, water hole 3, rubble layer 4, aluminium modified soil layer 5, aqueduct 6, sedimentation basin 7, soil
Earth layer 8, buffer pool 9.
Fig. 2 is to apply aluminium modified clay and do not apply treatment effect pair of the soil to runoff simulation sewage of aluminium modified clay
Than figure.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing:
As schemed, 1 shows, in the buffer pool 9 of loke shore buffer strip building bottom slope≤15%, the water inlet and source of sewage of the buffer pool
Connection, water outlet are connected to by outlet pipe 1 with lake.Several water retaining dikes 2, adjacent gear are built along gradient direction heap in buffer pool 9
Buffer area (not indicating in figure) is formed between water dike 2；The connection adjacent two-stage buffering is offered on water retaining dikes 2 at different levels
The water hole 3 in region, the water hole 3 on adjacent water retaining dike 2 are dislocatedly distributed along shelves water dike short transverse.The bottom of buffer areas at different levels
Successively paving fills out rubble layer 4, soil horizon 8, aluminium modified soil layer 5 from bottom to top in portion, or successively paving fills out aluminium Modified soil from bottom to top
Earth layer 5, soil horizon 8, rubble layer 4.In order to guarantee to obtain good treatment effect, combine construction cost, rubble layer 4, aluminium
