Description
Technical field
The utility model relates to a kind of oil pollution treating apparatus, particularly relate to a kind of be applied to large-scale intake block dirt and anticollision device, collision-prevention device.
Background technology
The burst contamination accident that goes from bad to worse is the important threat of domestic and international most city water head site safety and urban water supply safety.Huangpu River is one of main water head site of Shanghai Urban water supply, and upper reaches getting water from water head site scale is 7,050,000 m
3/ d has accounted for the whole city and has concentrated 80% of former water supply.Huangpu River water head site is owing to be located in open, mobile, multi-functional waters, and water head site is influenced by sudden water pollution accident, and there is high risk in intake.
Huangpu River burst Pollution accident takes place frequently in recent years, and water head site water quality has been caused serious threat.Wherein, marine incident is a primary pollution source.In all sudden marine incidents, cause the incident that pollutant leaks to have 830, wherein the oil leak incident has accounted for the overwhelming majority, and other has a small amount of chemical leakage incident.The especially big Pollution From Ships incident that particularly day and night took place in accurate water conservation district August 5 in 2003 is leaked fuel oil up to 85t, causes greasy dirt field to be about the large-scale pollution of 10km, and intake is constituted direct threats.Urgent with all strength still 15d consuming time of greasy dirt, expensive 1,700 ten thousand yuan removed of army and police of the whole city and professional people more than 2000.
Huangpu River is a tidal river.Research shows that morning and evening tides and wave action are the main drives of Pollutants Diffusion, and simultaneously, the runoff effect in river moves diffusion for pollutant defeated and also plays a role.For the sudden oil pollution of Huangpu River, runoff and trend interact, and have increased the difficulty that water head site oil pollution is handled.
The oil pollution processing method has physical treatment process, method of chemical treatment and biological treatment at present.Traditional oil fence is in the further diffusion that can prevent oil slick than the correct use in flat water effectively.That biological treatment exists is efficient, the advantage of economy, safety, non-secondary pollution, but in case large-scale oil pollution accident appears or oil reservoir thicker, oxygen is not enough with nutrition supply, owing to bacterial growth is suppressed the removal effect that can influence greasy dirt thus.Sudden oil pollution accident takes place near the large-scale intake of tidal river, and sudden oil pollution accident needs respond simple processing method fast and the requirement of fast processing particularly can't satisfying on the processing speed on processing mode and the equipment requirements.
Therefore, for a long time, owing to lack preprocess method effectively and rapidly, cause the water head site oil pollution can't fast processing, the intake safety water supply is constituted a serious threat, aggravated the burden of water works water treatment.For this reason, press for a kind of pretreatment system of searching to the sudden oil pollution of the large-scale intake in tidal river.
