Description
Technical field
The present invention relates to a kind of technology for improving non-flood discharge river water ecological environment, a kind of module metaplasia
State permeable dike.
Background technology
Increase and the quickening of urbanization process due to China's population in recent years, the excess emitters sewage of cities and towns industry and agriculture
With chemical fertilizer, a large amount of uses of pesticide, causing the severe contamination of water quality of river, some areas form black and odorous water, not only give the masses
Bring the sensory experience of extreme difference, be also the prominent water environmental problems directly affecting masses' productive life.
2015, house town and country construction portion took the lead, and has worked out " city together with ministries and commissions such as Environmental Protection Department, Ministry of Water Resources, the Ministry of Agriculture
City's black and odorous water renovation guide ", the target of city black and odorous water renovation, principle, workflow etc. are made that bright
Really regulation, and identification, classification, renovation scheme preparation method and the selection of remedial technology and effect to city black and odorous water is commented
Estimate, policies and mechanisms guarantee proposes and clearly requires.According to " guide ", before the end of the year in 2015, region and above city are built up
District should complete water body investigation, announces black and odorous water title, person liable and time limit up to standard；Before the end of the year in 2017, region and above city
Built-up areas, city should realize river surface without large area floating thing, and riverbank is without rubbish, without illegal sewage draining exit；Municipality directly under the Central Government, provincial capital, plan
Built-up areas, single-row city substantially eliminate black and odorous water.
Specify that the concrete technology administering black and odorous water at " city black and odorous water renovation guide ", mainly include control source
Cut dirty technology, endogenous Treatment process, ecological reestablishment and other control measures.Ecological permeable dam is river corridor restoration technology
One, in engineering, main application is that the runoff of non-flood discharge river or reservoir is retained.
Pollute for river water quality and Ecology destroys situation, the most effectively utilize ecological reestablishment measure, to river
Road water quality is improved, and repairs water ecological environment.Actual application needs the problem solved as follows:
