Description
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of upright shore protection zone area source pollution purifying system of embankment combination.
Background technology
Pollution of area source, the pollutant that is meant dissolving and solid is from nonspecific place, under the souring of precipitation or snow melt, import receiving water body (comprising river, lake, reservoir and bay etc.) and cause other forms of pollutions such as organic contamination, body eutrophication or poisonous and harmful by the runoff process, have the characteristics such as randomness, pollutant emission time and approach uncertainty, pollution load space and time difference are big that take place, its contribution rate that basin is polluted accounts for 66%, has become the principal element that pollute in China basin.According to the characteristics of pollution of area source generation area and process, generally it is divided into city and widespread pollution from the overuse of fertilizers and pesticides in rural area two big classes.Wherein, city surface source pollution is because of containing a large amount of pollutants in the initial stage runoff, and the pollution load of its generation is far above city domestic sewage; Widespread pollution from the overuse of fertilizers and pesticides in rural area accounts for 60～80% of pollution of area source total amount.
At present, actively developed source, opposite study on pollution control both at home and abroad, according to the difference of pollutant present position, the control countermeasure can be divided into the source and control, controls and end treatment midway.Wherein the end treatment technology has buffer strip, ecological revetment, vegetation to cut dirty band, rainwater sedimentation basin, oxidation pond and wet land system etc., and these technology often are subjected to the restriction of conditions such as urban architecture, bank occupation of land in the city, it is bigger to implement to transform difficulty, and cost is also very high; And in the rural area, the shore bank buffer strip technology and the Wetland ecological technology of employing also need take a large amount of spaces, place, bank, are unfavorable for promotion and implementation.Therefore, the existing end treatment of carrying out pollution of area source in conjunction with channel revetment self lineament of researching and proposing, as patent of invention: a kind of efficient ecological bank slope construction process (China Patent No. ZL200610161264.0) of removing pollution of area source fast at staged shore protection district application, the embankment slope is proposed along the river to setting up three grades of filter bed systems between the river water body, order is three grades of filter beds from top to bottom, secondary filter bed and one-level filter bed, and arrange by the staged mode; And at the patent of invention of ramp type shore protection application: big-and-middle river course compound platform surface source is held back cleaning system (China Patent No. ZL200810123577.6), proposition is provided with the cross section in the junction of riverway slope and compound platform be trapezoidal interception traverse furrow wide at the top and narrow at the bottom, in the compound platform by from the middle of the river from far near order successively fill the different-grain diameter gravel, concrete brick is laid at the compound platform top, water one side in shore is set to the slope revetment, lay the non-fine concrete building block on the revetment of slope, and form submerged plant group according to depth of water height plantation successively, floating plant group and emergent aquactic plant group.
Above-mentioned various pollution of area source measures in conjunction with the employing of sloping bank landform all have ladder or space, ramp type place because of the bank protection outside; And in the river course, basin common upright shore protection district, upright because of its shore protection outside, do not have enough place construction space to implement above-mentioned source end treatment measure.Therefore, at the narrow and small own characteristic in space, place, upright shore protection district, seek and a kind ofly can show important especially with the compatible mutually pollution of area source purification method of land used situation.The upright shore protection district control pollution of area source technology that this time proposes, be to consider that the bank protection outside, upright shore protection district does not have on the basis in short supply of space, place, inboard land resources, rely on upright bank protection in both sides, river course and bank, carry out certain structure and handle, reach the maximization of polluting control and benefit with the control pollution of area source.
Summary of the invention
Technical problem to be solved by this invention is do not have enough spaces, place at present to implement existing pollution of area source improvement technology at upright shore protection district, in conjunction with upright shore protection own characteristic, provide a kind of upright shore protection zone area source pollution purifying system of embankment combination.
The present invention solves the problems of the technologies described above the technical scheme of being taked: a kind of upright shore protection zone area source pollution purifying system of embankment combination, this cleaning system is located at below the face of land of upright shore protection inboard, and described cleaning system is by introducing mechanism, and purifying layer structure and drainage mechanism constitute, wherein
