Abstract
The utility model relates to a runoff pollution control device, in particular to an initial runoff pollution intercepting device, which is mainly positioned on a slant slope surface and comprises an adsorbing purification groove, a filling material, a lower infiltration layer, a head cover and an intercepting area, wherein the head cover has a high front part and a low rear part along the slope surface, and covers the groove-shaped adsorbing purification groove, the internal space of the adsorbing purification groove is filled with the filling material, the bottom end of the adsorbing purification groove is communicated with the lower infiltration layer, and the intercepting area is arranged on the rear end surface of the groove opening of the adsorbing purification groove. The initial runoff pollution intercepting device disclosed by the utility model has a simple structure, is convenient to construct and manage, and can be used for effectively intercepting initial runoff pollutants in rainy or snow melting days, so that the burden of the follow-up treatment on structures is greatly reduced, and the costs of investment and operation are saved.
Description
Technical field
The utility model belongs to sewage disposal device, and specifically, it relates to a kind of runoff pollution control device, especially a kind of initial stage runoff pollution blocking apparatus.
Background technology
Along with quickening of urbanization process, waterproof floor area increases sharply, and city surface source pollution highlights day by day.It is the chief component of city surface source pollution that rainfall runoff pollutes, especially the initial stage runoff pollution.Chinese scholars research shows that the water quality of early-stage rainwater runoff is relatively poor, in a rainfall, accounts for the initial stage runoff of yielding flow 20% or 25%, washes away and has discharged 50% of runoff blowdown flow rate.Therefore, the processing to the early-stage rainwater runoff is the key problem in technology of rainfall runoff pollution control engineering with disposing.
Adopt the disposal options of abandoned stream at present for the early-stage rainwater runoff more; Usually through control certain rainfall dark/depth of runoff or the certain rainfall duration/runoff runoff in lasting realizes; But because the early-stage rainwater runoff receives multiple factor affecting; The abandoned stream amount does not have unified design formulas, therefore is difficult to control.Simultaneously, there is another kind of drawback in the disposal options of abandoned stream.Major pollutants in the early-stage rainwater runoff are SS and COD, and abandoned stream will cause the conveyance conduit deposit to increase, and Wastewater Treatment Plant's pollution load raises, and the operational management cost increases thereupon.Domatic and general ground is compared, and the rainfall runoff flow velocity is very fast, collects comparatively difficulty, and also rarely has research.
Summary of the invention
The purpose of the utility model is to design and develop a kind of initial stage runoff pollution blocking apparatus, and the early-stage rainwater runoff is dammed and disposal effectively.
This initial stage runoff pollution blocking apparatus comprises adsorption cleaning groove, filler, following infiltration layer, top cover and interception band.Said adsorption cleaning groove is in the form of slot, and top cover covers on the adsorption cleaning groove, and low along domatic preceding high back, adsorption cleaning bottom land end communicates with following infiltration layer, and filler is filled in adsorption cleaning groove inner space, and interception is with and is arranged at adsorption cleaning groove notch rear end face.Described filler is a porous adsorbing material, and porous adsorbing material can mix for active carbon, zeolite and haydite equal proportion fills or the layering filling, and packed height should be not more than 2/3rds of adsorption cleaning groove height overall.Described infiltration layer down is that the rubble accumulation forms, and void content is greater than 20%.Described top cover is a Reinforced Concrete Materials, has certain bearing capacity, and top cover has the aperture that diameter is 2cm, and pitch of holes is about 15cm, is convenient to runoff sewage and flows into the adsorption cleaning groove.Interception band is arranged on adsorption cleaning groove notch rear end face domatic, bottom and ground driving fit.
Initial stage runoff pollution blocking apparatus by such scheme constitutes is simple in structure; Construction and convenient management not only can be collected and dispose the early-stage rainwater runoff effectively, have alleviated the burden of subsequent treatment structure; Practice thrift investment and operating cost, and replenished underground water to a certain extent.
Description of drawings
Fig. 1 is a kind of initial stage runoff pollution blocking apparatus sketch map.
Wherein, 1-adsorption cleaning groove; The 2-filler; Infiltration layer under the 3-; The 4-top cover; 5-tackles band
The specific embodiment
Below in conjunction with sketch map the utility model is described further:
Shown in figure, this utility model mainly is with 5 to form by adsorption cleaning groove 1, filler 2, following infiltration layer 3, top cover 4 and interception.Adsorption cleaning groove 1 is in the form of slot; Filler 2 is filled in the inner space, and the bottom joins with following infiltration layer 3, and filler 2 is a porous adsorbing material; Can mix for active carbon, zeolite and haydite equal proportion and fill or the layering filling; Packed height should be not more than 2/3rds of adsorption cleaning groove 1 height overall, and following infiltration layer 3 is piled up for rubble and formed, and void content is greater than 20%.Top cover 4 is a Reinforced Concrete Materials, covers above adsorption cleaning groove 1, and is low along domatic preceding high back, has certain bearing capacity, has the aperture that diameter is 2cm on the top cover 4, and pitch of holes is about 15cm, is convenient to runoff sewage and flows into adsorption cleaning groove 1.Interception with 5 be arranged at adsorption cleaning groove 1 rear end face top, bottom and ground driving fit.Rainfall forms the runoff initial stage; The initial stage runoff rainwater of carrying a large amount of pollutants secretly is along domatic flowing downward, and during through this device, rainwater is with 5 to stop the outlet by interception; Flow into adsorption cleaning groove 1 by the aperture on the top cover 4; The filler 2 of flowing through then, the particulate pollutant in the runoff water body is adsorbed by porous adsorbing material, water body continue to flow downward get into down infiltration layer 3 and along each in infiltrating soil.Along with the propelling of rainfall duration, the runoff quantitative change is big, and the speed of footpath stream is greater than the speed of oozing down in installing, and the runoff water body is with 5 front ends constantly to accumulate in interception, is with 5 to continue along domatic flowing downward when accumulation highly is higher than just to cross when 5 peaks are with in interception to tackle.Filler 2 in the adsorption cleaning groove 1 needs periodic replacement, changes frequency and decides according to various places ground pollution accumulation situation and rainfall situation.This initial stage runoff pollution blocking apparatus is simple in structure, and construction and convenient management in to initial stage runoff collection and treatment, have also replenished groundwater resources effectively.
