Description
Technical field
The utility model relates to a kind of Highway Rainfall Runoff treatment system.
Background technology
At present, at highway communication engineering field, the runoff that highway pavement is formed mostly adopts and freely discharges or simply pass through drainage system and collect rear directly entering in periphery agricultural irrigation irrigation canals and ditches, natural irrigation canals and ditches or river.But, in road construction or operation process, road will produce all multi-pollutants, mainly comprise road dust rubbish, tire wear particle, ground surface material wear particle, transport reveal dirt, brake linkage produce particle and other pollutants etc. relevant with road construction or vehicle operating.When precipitation forms pavement runoff, these pollutants are carried under one's arms wherein, if not treated direct discharge, can the water environment of near Highway be impacted or be destroyed, especially these pollutants decompose the hazardous substances produced, to the fragile sensitizing range of water environment, the harmfulness as special road sections such as karst area, underground river entrances will be larger.Therefore, support in process in highway construction and pipe, be the water environment of available protecting road periphery, particularly in water environment sensitizing range, be necessary that road pavement runoff processes, to prevent or to reduce the impact of pavement runoff on periphery water environment.
Utility model content
The purpose of this utility model is to provide a kind of Highway Rainfall Runoff treatment system; pavement runoff water is significantly reduced by various floating thing, particulate pollutant after this system process; can the water environment such as farmland, irrigation canals and ditches better near highway safety, be particularly useful for the protection of the water environment sensitizing range such as karst area, underground river entrance.And its process is easy, processing cost is cheap, easily with popularization.
The technical scheme in the invention for solving the technical problem is, a kind of Highway Rainfall Runoff treatment system, and its composition is:
The water inlet end of pretreatment pool is connected with the delivery port of let, and the water side of pretreatment pool is provided with the stone pier, and the gap location of the stone pier arranges coarse rack, and the water inlet end of sludge hopper is connected with coarse rack; The water side of sludge hopper is connected with the water inlet end of sedimentation basin, and the degree of depth of sludge hopper is greater than the degree of depth of pretreatment pool;
The water side of sedimentation basin is connected with the water inlet end of collecting-tank by overflow weir; The water side of collecting-tank is connected with the water inlet end of escape canal; And sedimentation basin length is more than 3 times or three times of pretreatment pool length, the bottom of sedimentation basin raises from water inlet end gradually to water side.
The utility model to the processing procedure of Highway Rainfall Runoff water and principle is:
The runoff water of highway pavement flows into after pretreatment pool carries out preliminary sedimentation by the delivery port of let, be greater than the sludge hopper of pretreatment pool again by the coarse rack penetration depth of the stone pier gap location of pretreatment pool water side, the floating thing in runoff water is then blocked in pretreatment pool by coarse rack;
The runoff water entering sludge hopper enters bottom subsequently and to raise gradually and the sedimentation basin that length is pretreatment pool more than three times precipitates again, and the overflow weir overflow that the clear water on upper strata overflows across sedimentation basin water side enters collecting-tank; The water flowed in collecting-tank flows into escape canal again and discharges through collecting-tank water side.
Compared with prior art, the beneficial effects of the utility model are:
One, water float thing is blocked in pretreatment pool by the coarse rack of pretreatment pool tail end, makes the runoff water after processing no longer include floating thing.Simultaneously, the stone pier of the tail end of pretreatment pool, interception function will be produced to current, slow down the movement tendency of current, reduce its kinetic energy and turbulence intensity, the water entering sludge hopper and sedimentation basin better can be precipitated, thus the solid sundries such as particulate pollutant are deposited at the bottom of pond well, the clear water on top layer then enters collecting-tank by overflow weir overflow, enters in the water environment of surrounding finally by collecting-tank outlet and escape canal.Make the Highway Rainfall Runoff water of the utility model process, pollutant significantly reduces, can the natural ecological environment such as farmland better near highway safety; Especially the protection of the protection of the water environment sensitizing range such as karst area, underground river entrance is beneficial to.
Two, the utility model passes through precipitation and the floating thing obstruction method of physics, achieve the floating thing of highway runoff water and the removing process of precipitable foreign material simply and easily, neither consume the energy, also without the need to being equipped with any machinery, electrical equipment or chemical device, its processing procedure is easy, processing cost is cheap, easily promotes.
Three, the degree of depth of sludge hopper is the darkest, and sedimentation basin prolongs water (flow) direction and increases gradually, and sediment is easily collected in sludge hopper, and the sediment do not collected on a small quantity in sludge hopper also can wash away easily in sludge hopper; Be convenient to sedimentary concentrated removing process.Reduce further processing cost of the present utility model.
Above-mentioned overflow weir is provided with bypass channel in sedimentation basin side.
Like this, add the overflow length of sedimentation basin top clear water and the time of staying of water body, improve the sedimentation effect of sedimentation basin; Too increase the load intensity of overflow weir simultaneously.
The bottom of above-mentioned collecting-tank is provided with coarse sand filtration beds.
Like this, through the filtration of coarse sand filtration beds, reduce further the impurity of water in collecting-tank.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
