National economy in recent years is fast-developing, but in terms of nature, history and the understanding due to, when considerably long
In, high investment, high consumption, heavily contaminated, the traditional development model of low output are not broken away from, more serious environment is caused dirty
Dye and ecological disruption, the river course in each city 70% is black and odorous water.City black and odorous water not only brings the sense organ of extreme difference to the masses
Experience, is also the protrusion water environmental problems for directly affecting masses' production and living.
On December 12nd, 2013, practise the General Secretary and spoken of in central urbanization working conference：" in lifting sewerage system
When to pay the utmost attention to limited rainwater to stay, pay the utmost attention to more utilization elements drainings, build nature accumulate, it is natural
Infiltration, the sponge city of self-purification ".In November, 2015, General Office of the State Council's issue《Finger on promoting sponge urban construction
Lead opinion》（The Office of the State Council sends out (2015) No. 75）, it is desirable to：By sponge urban construction, it is comprehensive take " ooze, it is stagnant, store, it is net, with, row " etc.
Measure, reduces influence of the city development construction to ecological environment, by 70% rainfall on-site elimination and utilization to greatest extent.Arrive
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
To target call.It is on April 2nd, 2015, issued by the State Council《Water prevention and cure of pollution action plan》Propose " by 2020, region and
Above completed region of the city black and odorous water is controlled within 10%, and by 2030, completed region of the city black and odorous water was totally disappeared
Except " controlling target.In August, 2015, the firmly portion's of building issue《City black and odorous water renovation guide》, further implement black smelly
Water body treating works.
The pollutant of black and odorous water mainly includes point-source pollution and pollution of area source.In fast urbanization process, soil is big
