Description
Technical field
The utility model relates to Water Pollution Control Engineering technical field, is specifically related to filter dam, a kind of river course formula rainfall runoff treatment system.
Background technology
At home and abroad in water pollutions treatment technology, applying more is physics, chemistry, biology and eco-treatment technology, and obtains good treatment effect.It is one of its source of polluting that early-stage rainwater runoff enters river course, the conventional mainly biology/ecological pollution reparation of current ecological restoration technology on river technology, Treatment process, because it is except having good result, also have good ecological benefits, economic benefit and being widely used at home and abroad.
Along with Chinese society expanding economy, the pollution load of early-stage rainwater increases gradually, and early-stage rainwater runoff accounts for city river pollution ratio and constantly increases, serious threat river channel ecology environment.Investigation data both domestic and external shows, the Initial Runoff that rainfall is formed contains a large amount of pollutents, and pollutant kind comprises COD, nitrogen phosphorus, heavy metal etc., and the influent quality of some Pollutant levels and municipal wastewater treatment plant is close even exceedes Sewage Plant influent concentration.Both at home and abroad the improvement of early-stage rainwater runoff is mainly set about from following several respects:
1. Sources decreasing, treatment in situ.By changing surface condition, what increase runoff infiltrates through underground, dispersion treatment early-stage rainwater, the mode that most city adopts porous material to pave ground reduces surface runoff amount, and to transform side drain be that grass planting waterways is to cut down early-stage rainwater run-off from source.This method to a certain degree can reduce just rain run-off, but the first rain runoff pollution of the comparatively large still inevitable existence of rainfall enters river course;
2. collect process of regulating and storing.Sewage work's process is entered after collecting rainwater by Storage devices, domestic have sewage work to have just rain to regulate and store device, utilize special efficient sedimentation tank process just rain rainy season, dry season, efficient sedimentation tank was used as the preliminary sedimentation tank of sewage, and the method can focus on first rain preferably, but due to rainfall not timing, need to take larger investment construction to regulate and store device, to investment and space requirement higher, and need manual maintenance to control, factors constrains the application of this technology.
3. in first rain end treatment technology, the normal mode of artificial swamp that adopts processes, but artificial swamp is only limitted to process the lower early-stage rainwater of pollution load, and the first rain removal effect larger to pollution load is limited;
4. strengthen maintenance management.Except needing except the impact maintenance of ground stores, rubbish, vehicle etc. that just rain pollutes, also needing to safeguard treatment process, current development and maintenance is easy, the first rain treatment technology of Automated condtrol will become future studies focus.
At present both at home and abroad just rain Environmental capacity control measures, exist above-mentionedly focus on that technology is single, storage project investment is comparatively large, safeguard inconvenience, end treatment technology to high loading just rain treatment effect limited, by problems such as the littoral site influence in river course are large.
