Abstract
The invention relates to a river enclosure pollution prevention and water diversion in-situ purification treatment method and system. The method comprises the following steps: rapidly and completely intercepting sewage at a drain outlet by utilizing a pollution prevention enclosure device, forming a pollution prevention and water diversion purification tank on a riparian zone, performing in-situ purification on the sewage in the pollution prevention and water diversion purification tank in the diversion process by utilizing a bottom micro-porous aeration device and floating plants, guiding the sewage into a centralized sewage purification area on the downstream, performing strengthened purification, and eliminating pollutants, so that complete pollution prevention and water quality improvement of a main river control section can be realized. According to the method and system disclosed by the invention, river water does not need to be pumped up during construction, and river black and odor causing substances and pollutants such as nitrogen, phosphorus and the like can be rapidly and completely intercepted and treated in a centralized manner. The method and the system are applicable to black-odor river control projects for directly discharging domestic sewage on two banks along the river and agricultural wastewater in towns and villages.
Description
Technical field
The invention belongs to the technical fields such as waste water control, restoration of the ecosystem, specially black-odor riverway purified in situ technology and life
State recovery technique.
Background technology
China's river course quality of water environment drastically declined in nearly 20 years, and most water quality of river belong to bad V class, and water quality is dirty
Dye and Ecological degenerative problem are very prominent, and reproducibility organic pollution and nitrogen, phosphorus recycling content are high, or even occur in that
Perennially black and odorous water phenomenon.This not only hampers the sustainable development of economic society, has also had a strong impact on the strong of littoral resident
Health and life.The black smelly phenomenon for eliminating river course, the ecological functions for recovering river course turn into the key during social sustainable development
One of task.
China is in recent years attaching great importance to the improvement of black-odor riverway, is devoted to the research of Treatment process and puts into practice, mesh
The river regulation technology that preceding China carries out mainly has：Physical method, including artificial aeration, Sediment Dredging and water transfer etc., by carrying
Water body oxidisability high, control endogenous pollution and dilution pollutant etc. alleviate black and odorous water, but it cannot be guaranteed that water quality it is long-term steady
It is fixed to improve；Chemical method, main including flocculation, chemical oxidation etc., the use of such as molysite aluminum salt can effectively improve water
Body transparency and absorption dissolved phosphorus, CaO2、MgO2Dissolved oxygen can be improved, contributes to the conversion of organic matter degradation and ammonia nitrogen,
And release of the bed mud to phosphorus in overlying water is alleviated, this method, patent document are just employed in patent 201610320572.7
Dissolved oxygen is provided using nano bubble machine in 201610076802.X, produced bubble diameter very little is not almost made to water body
Into disturbance, the bubble of generation can adhere to bed mud top layer, and oxygen transfer rate is high；Biological-ecological method, patent document
Biofilm on 201510845266.0 early carbon fiber ecological grass, and starting end to black-odor riverway difference waters section sprayed after culture
Indigenous microorganism, this is to make use of technology of biological membrane and microorganism enhanced technology, and the microorganism on biomembrane can adsorb drop
Solution pollutant, promotes the chemical reaction process of pollutant, and patented invention 201610006876.6 provides a kind of structure stabilization
Submerged vegetation group method, set up evergreen type submerged vegetation using the combination of waterweed-eel grass, and plant companion species for goldfish
Algae, Haloragidaceae Myriophyllum spicatum, hydrilla verticillata, and lift floating bed is used, the depth of floating bed can be adjusted according to water transparency, this is profit
With plant purification technology, the technology being widely used at present has water plant oxidation pond, biological floating bed etc..
However, most of river regulation patented technologies are all concentrated in purified in situ reparation at present, to xenobiotic pollutants
Shunting, section dirty and disposal technology are less, and patent document 201510847564.3 is related to water conservancy diversion and purification to entering river sewage, and it will
River course opsition dependent is divided into sewage water conservancy diversion and collecting region, deep purification of waste water area, water ecosystem build and purification of water quality area,
And control measures are taken to three regions respectively, its described sewage water conservancy diversion and collecting region are in a width of 0.5~2m in river course both sides
Region sewage is collected using PVC microporous barriers and water conservancy diversion, but blocking is easily caused using PVC microporous barriers, need frequently more
Change, usage cycles are not long, and specific laying to pipeline and connection are described in detail.
In view of above-mentioned technical background, for cities and towns and rural area, two sides sanitary sewage, agricultural wastewater are straight by sewage draining exit along the river
Enter river, cut the dirty not big black-odor riverway harnessing project of the thorough, discharge of sewage, invent a kind of mode of quick and complete section of dirt,
River course need not be drained to lay the enclosure that is constituted using floating body, waterproof cloth in river course both sides in the case of blow-off pipe will to enter river sewage complete
Portion collects and is guided to depth concentration purifying area, then using the mode of physics aeration, plant purification and microorganism combination to sewage
Processed, cut dirty thorough, clean-up effect is stablized for a long time, and quantities is small, environmentally friendly.
The content of the invention
Defect it is an object of the invention to overcome prior art, there is provided a kind of river course enclosure is cut at dirty water conservancy diversion purified in situ
The method and system of reason, described method and system quickly can thoroughly be intercepted and purified into river sewage, while in situ in river course
