Description
Technical field
The present invention relates to sewage treatment area, it particularly relates to a kind of primary rainwater purification apparatus.
Background technology
National economy in recent years is fast-developing, but the reason due to aspects such as nature, history and understanding, within considerable time, do not break away from the traditional development model of high investment, high consumption, heavily contaminated, low output, causing comparatively serious environmental pollution and ecological disruption, the river course in each city 70% is black and odorous water. City black and odorous water not only brings the sensory experience of extreme difference to the masses, is also the prominent water environmental problems directly affecting masses' productive life.
On December 12nd, 2013, practise the General Secretary to speak of in central authorities' urbanization working conference: " to pay the utmost attention to when promoting sewerage system and limited rainwater is stayed; pay the utmost attention to more elements draining that utilizes, build the sponge city of nature accumulation, naturally osmotic, self-purification ". In November, 2015, the General Office of the State Council issues " instruction about advancing sponge urban construction " (Office of the State Council sends out (2015) No. 75), require: by sponge urban construction, comprehensively take " ooze, stagnant, store, clean, with, row " etc. measure, reduce the city development construction impact on ecological environment to greatest extent, by rainfall on-site elimination and the utilization of 70%. To the year two thousand twenty, the area of completed region of the city more than 20% reaches target call; To the year two thousand thirty, the area of completed region of the city more than 80% reaches target call. On April 2nd, 2015, " water prevention and cure of pollution action plan " issued by the State Council proposes the controlling target of " to the year two thousand twenty; region and above completed region of the city black and odorous water all control within 10%, to the year two thousand thirty, completed region of the city black and odorous water is totally eliminated ". In August, 2015, live the portion of building and issue " city black and odorous water renovation guide ", implement black and odorous water control further.
The pollutant of black and odorous water mainly include point-source pollution and pollution of area source. In fast urbanization process, soil is developed rapidly by extensive, but water pollution control and city management relatively lag behind, earth's surface, urbanization district have accumulated a large amount of nitrogen and phosphorus thing, microorganism, heavy metal and organic toxic substance, during heavy rains, these materials are washed in entrance runoff, form pollution of area source. Showing according to reservoir watershed at Shenzhen dan rock and the investigation of source, face, front sea area, Bao'an result, pollution of area source accounts for annual warehouse-in, enters the 30-50% of sea pollutional load.
