Description

PM for particulate matter integrated purifying device in rainwater, the sewage
Technical field
The utility model relates to rainwater, technical field of sewage, the refining plant of particularly a kind of rainwater, sewage.
Background technology
Along with fast development of urbanization, the non-point pollution that is caused by rainfall runoff becomes the important source of urban water-body pollutent gradually.Pollutent in the urban rainwater runoff is mainly derived from wet deposition that precipitation drip washing atmospheric polluting material causes and the leaching of city impermeable surface pollutent washes away, and the latter accounts for more than 90% of the rainfall runoff total amount of pollutant.PM for particulate matter is the main carrier of city impermeable surface pollutent; Such as: a large amount of pollutents that PM for particulate matters such as the settling on atmospheric precipitation, vehicle exhaust, tire wear, Snow Agent, the construction site, solid refuse and percolate contain (COD, nutrition, organism, heavy metal, pathogenic agent etc.); Finally all will under rainwater drip washing, souring, migrate in the receiving water body, and its ecotope will be produced serious harm.PM for particulate matter in the rainfall runoff also can cause the receiving water body turbidity to raise, and therefore, it has been generally acknowledged that PM for particulate matter is the potential component that the composing environment water quality worsens.In addition, PM for particulate matter can produce deposition in pipeline after getting into the urban discharging pipeline system under the rainfall runoff souring, form pipeline sediment pollution and waterlogging disaster.Nearly all there is depositional phenomenon to a certain degree in present urban discharging pipeline all over the world, and in Europe, the sedimental average sedimentation rate of pipeline is 30-500g/md.Find that through 72 inspection chambers in Xicheng District, Beijing being connected the drainage pipeline investigation thickness of deposits accounts for 20% ~ 30% of caliber in 41.67% the pipeline, greater than 50% account for 4.16%.PM for particulate matter deposits reduction, the waterlogging disaster that not only can cause corrosive pipeline, current transport capacity and takes place frequently in pipeline; And under the souring of strong rainfall runoff; Wherein accumulation is composed the pollutent deposit and can be discharged into urban water-body again, and the water surrounding of receiving water body is constituted a serious threat.
Pollute to the PM for particulate matter in the rainfall runoff, domestic and international existing treatment technology comprises filtration, sediment by rotational flow, deposition and infiltration/filter etc.Filtering technique generally is used for rainwater catchment system, is divided into on-line filtration and off-line again and filters, and filtration medium commonly used comprises fillers such as fine sand, gravel, haydite; Filtering technique is high to the PM for particulate matter clearance in the rainfall runoff; Can reach more than 90%, but easy blocking, maintenance cost is higher.The sediment by rotational flow technology is mainly used in the sedimental control of urban discharging pipeline system, can be divided into unpowered cyclone separator and power cyclone separator again.The operation work of unpowered cyclone separator need not by the external impetus condition, can realize its normal operation through the head fall of utilizing field condition; The operation work of power cyclone separator then need could realize that it runs well by the external impetus condition, i.e. industry such as oil, chemical industry hydrocyclone commonly used.Abroad in the research and application of rainwater and interflow rain sullage rotational flow separating treatment; The unpowered cyclone separator has not occupied dominant position because of it has advantages such as energy consumption, floor space is little, section dirty efficient is high, suitability is strong; But generally can only remove the bigger PM for particulate matter of particle diameter, clearance is relatively low.Traditional rainwater deposition adopts the static weight precipitate and separate mostly.Promptly in rainfall, at first rainwater is collected into deposition facility, treats that rain stops back redeposition for some time, supernatant is taken out use or discharging entering subsequent disposal structures.Under this processing mode, if will realize effective processing of runoff rainwater, must guarantee the processing volume of deposition facility, floor space is relatively large.Infiltration/filter facility is mainly used in rain penetration recharge groundwater or rainwater catchment system, comprises infiltration irrigation canals and ditches, vegetation shallow ridges, rainwater garden, seepage basin/pool etc., and such facility PM for particulate matter clearance is higher, but general processing power is less.
