Embodiment
With reference to Figure of description, the present invention will be further described.
As shown in Figure 1-2, the present invention provides a kind of Polluted Urban inland lake purification of water quality and Water Ecological Recovery method, is entering
Along the river the inlet for stom water (or mixing sewage overflow mouth) 1 in lake river course 5 is discharged at river course, sets rain sewage disinfection treatment purifying area 2, rain dirt
Water pretreatment purifying area 2 sets multistage multiple aperture intercept net 3, intercepts different-grain diameter suspension, then enters through filler clean unit 4
Row catalytic oxidation, realize the pretreatment of inlet for stom water (or mixing sewage overflow mouth) 1 pollutants discharged into rivers along the river.
Wherein, intercept net 3 can use the ecological nethike embrane of multilayer different pore size.Filler clean unit 4 is hung on using floating body
Rain sewage disinfection treatment purifying area, pass through microbial film purifying contaminated thing accompanying by filler.In the water of rain sewage disinfection treatment purifying area 2
Plant absorption unit is set on face, it surrounds piece using fishing net as carrier, by phytosphere, plants the strong fluitante of dirt-removing power,
By periodically gathering in more new plant, pollutant is removed.
Lakebed micro-slope reconstruction is carried out to contaminated inland lake, builds shallow water hydrophyte restoration area successively from loke shore to the middle of a lake
15th, gentle slope transition region 16, deep water are regulated and stored area 7.Regulated and stored the earth excavation of area 7 using deep water, enter exit of a lake free waters in broken end creek
Heap epeirogenetic domain ecology channelizing island 11, formed in the both sides of land-based area ecology channelizing island 11 that Xin Dui makes and concentrate excessively stream area, do not influenceed normal
Water drainage；Regulated and stored 7, area earth excavation using deep water, shallow water submerged plant recovery district 15 is reverted in nearly loke shore one fixed width, created
Make the base condition of submerged plant recovery；Regulated and stored in deep water and nature gentle slope is used between area 7 and shallow water submerged plant recovery district 15
Connection, form gentle slope transition region 16.
Rainwater imports lake through stream entering lake 5 from the both sides of land-based area ecology channelizing island 11 after pretreatment, in rainy season through lake outlet
Flow out lake and drain into downstream in road 14.But after rainfall terminates, a large amount of pollutions rest on river course and lake, cause water quality deterioration, simultaneously
The stream entering lake 5 of non-flush period is in addition to sewage is discharged into, and without external water source, water quality is in deterioration.To solve the creek water quality deterioration that breaks end,
Now start the circulating pump 8 for being arranged at the middle of a lake 7, middle of a lake water body is delivered into lake by the circulating line 9 through being embedded in lake (river) bottom
River course 5 (or lake outlet road 14), forms stream entering lake 5 (or lake outlet road 14) and deep water is regulated and stored the water circulation in area 7, and delivery port is adopted
It is uniformly dispersed water outlet with porous outlet pipe 10, prevents water outlet from washing away river sediments, cause water turbidity to increase.
Shallow water submerged plant recovery district 15 is made in nearly loke shore, the loke shore in the nearly river course side 6 in lake recovers the heavy water of anti-pollution type
Plant, the loke shore in remote river course side recovers clear water type submerged plant, and launches zoobenthos and zooplankter, recovers Aquatic Ecosystem 2
System, keep lake body water stabilization.
As the further improvement of this hair invention, formed on the water circulation section of the both sides of land-based area ecology channelizing island 11
Excessively stream purifies path, i.e., waterproof enclosure 13 is set on the water circulation section of the both sides of land-based area ecology channelizing island 11, impermeable
The perforate of water enclosure middle and lower part forms the concentration excessively stream area of water circulation, and (or the lake outlet road 14) water body of stream entering lake 5 and deep water are adjusted
Storing the water body of area 7 is concentrating excessively stream area to flow through.
Fixed filler cleaning system is arranged on wider excessively stream purification path, fixed filler cleaning system is sunken to lake
Bottom, excessively stream water body are removed by microbial film degraded inside fixed filler cleaning system；Float bed type filler cleaning system is arranged
Path is purified in narrower excessively stream, floats on the water surface, purifying contaminated thing does not influence river drainage simultaneously.Fixed filler purification system
System and float bed type filler cleaning system carry out oxygen supply aeration by watercourse aeration system, and watercourse aeration system can use fixed
Or float type installation.Fixed filler cleaning system and float bed type filler cleaning system arrange the quantity and aeration quantity of filler,
It is determined according to filler purifying contaminated load, present situation and target water quality, water quality reaching standard time.Fixed filler cleaning system and
During float bed type filler cleaning system start-up, purification of water quality microbial inoculum is added by external source, promotes biofilm.
As illustrated, submerged water catalytic oxidation cleaning system 12 is fixedly mounted in excessively stream purification path, the bottom is submerged in, and
Watercourse aeration is carried out to contact oxide regions, when circulating water body flows through submerged water catalytic oxidation cleaning system 12, by contacting oxygen
Change to strengthen and remove organic matter, ammonia nitrogen pollutant, waterproof enclosure 13 is packed up in rainy season, expand water drainage section, recover land-based area ecology
The water drainage passage of the both sides of channelizing island 11, do not influence normally to drain flooded fields.
More than, only presently preferred embodiments of the present invention, but protection scope of the present invention is not limited thereto is any to be familiar with sheet
Those skilled in the art the invention discloses technical scope in, the change or replacement that can readily occur in should all be covered
Within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by the protection domain that claim is defined.
