Description
Technical field
The invention belongs to water treatment fields, and in particular to a kind of rain reclamation and treatment system suitable for garden landscape.
Background technique
China is the country that water resource lacks, and the recycling of water resource is the important means for solving water resource and lacking.With
Urbanization process is goed deep into, and the impermeable surface area such as road, landscape, bridge, building in China city also constantly increases
Long, this results in the rainwater that may penetrate into soil originally that can only wash away now in these impermeable surface flows；Due to
These impermeable surfaces often accumulate the pollutants such as a large amount of dusts, rubbish, and the scrubbed atmosphere of rainfall, wash away city and build
It builds, has swept along a large amount of pollutant.
It is more severe, as urban population is more and more, car ownership, asd number, industry and house refuse
Amount constantly increase, and modern science and technology allow insecticide, deicing salt, pesticide etc. using dirt that is all-pervasive, being swept along in rainfall runoff
Contaminating object includes a large amount of suspended particulate, floating material, organic matter, heavy metal, bacterium etc., and the pollutant in these rainfall runofves is almost
It all concentrates in several millimeters of rainwater of rainfall initial stage, pollutional load is much higher than middle and later periods rainwater, the initial rainwater in some areas
Pollutant index peak is much higher than typical urban sanitary sewage, therefore is that rainwater recycle utilizes to the processing of initial rainwater
Key problem in technology,
China majority city is still in the primary stage to the processing of rainfall initial stage rainwash, at present to rainwater or initial stage rain
Water runoff mostly uses in line disposal options to be discharged into natural water, it is difficult to be effectively treated, it more difficult to accomplish the recycling benefit of rainwater
With.
Since environmental problem is increasingly highlighted in today's society, people pay attention to environmental protection further, and traditional rainwater is in line
It is not able to satisfy requirement of the people to environmental protection, with constantly improve for citizen's ecological, environmental protective theory, traditional in line processing is more next
More people are denounced.Currently, the theory of " ecocity " has been beaten into the every field of engineering by European and American developed countries；With
China carry forward vigorously construction ecology accumulate, ecology infiltration, ecological purification " ecocity " requirement, rainwater innoxious or return
Receipts processing is increasingly taken seriously.
City and scenic spot of today more and more emerge the ecological landscape of the garden of the big scale of construction, the earth's surface rain in these places
Water runoff component is simultaneously uncomplicated, and difficulty in filtration is lower, and water body quality is good after purification, recycling and recycling valence with higher
Value.And in reality, these valuable water resources are made after often doing simple collection by direct emission or only for flushing or non-economy
Object is irrigated.
Summary of the invention
The object of the present invention is to provide it is a kind of can high efficiency filter rainwater, can be used for sewerage system, ecology garden landscape,
The recovery and processing system that can effectively collect simultaneously purifying rainwater of water-deficient area etc..
Material is purified using waste and agricultural by product as Partial filtration it is a further object to provide a kind of
The rain reclamation and treatment system of material.

2, it by proportion optimizing, uses and is with ANTHRACITE FILTER MEDIA, quartz sand, yellow sand, Magnaglo, active carbon, zeolite powder
The second main filter layer effectively can filter and adsorb bacterium, macromolecule contaminant and nanoscale suspended particulate in rainwater, mention
High filter effect, carries out deep layer purification to rainwater, long service life can reuse after backwash activation.
3, using upper layer reservoir, the double layer design of lower layer's settling tank reduces occupied area, shortens rainwater and is being recycled
Purifying paths in system, it is energy saving.
4, when amount of rainfall is smaller in sedimentation basin, water level is lower, removes most of pollutant using natural subsidence, save energy
Source and artificial, loss of the reduction to filter device；When Rainfall runoff is larger, filter device is opened, improves water process amount.
5, rainwater enters filter vat by filter core after naturally osmotic filters in settling tank, is then sucked by Filter column
Filter, this set can greatly reduce disturbance of the filter device to water body in settling tank, avoid leading due to mechanical oscillation etc.
Cause the secondary muddiness of water body in settling tank.
6, it is long to considerably increase passage path of the rainwater through primary filtration in Filter column for the design in helical form filtering road
Degree, ensure that filter effect.
7, the electrification suspended particulate, micelle and the macromolecule contaminant that make in rainwater of dirt collection bag and spoiler are along spiral
It is captured under the action of the positive and negative electric field that the first and second electrode plate is formed by dirt collection bag in the way that shape filtering road is advanced and is enriched with it
It is interior.
8, Filter column is spliced by two semicylinders, convenient for dismantling cleaning；Applied by double of cylindrical cavity body
Air pressure makes dirt collection bag turn up, and becomes prone to clean.
9, the first filter core layer is due to making its guarantor containing organic principles, the culture mediums that can be used as sewage treatment strain such as corncobs
It deposits and breeds, when filter vat is placed in settling tank, has part of contaminated water processing strain and enter in settling tank water body, increase rainwater
Purified treatment effect；And due to the presence of the second filter core layer, sewage treatment strain is difficult to enter filtering by the second filter core layer
In column, pollution of the sewage treatment strain to water body in clarifier-tank is prevented.

| Coloration | 29 |
| Turbidity | 7 |
| It smells | Without unplessantness displeasure |
Embodiment 7
Rainwater filtered in embodiment 5 is handled again through Filter column, 12h is then stood in reservoir, takes upper layer
Water body is detected, and gained testing result is as follows：
| The project indicator | Detection data |
| pH | 6.9 |
| Total dissolved solid (mg/L) | 960 |
| BOD5(mg/L) | 9 |
| Ammonia nitrogen (mg/L) | 8 |
| Iron (mg/L) | 0.25 |
| Total coli group (a/L) | 3 |
| Coloration | 24 |
| Turbidity | 6 |
| It smells | Without unplessantness displeasure |
As it can be seen that the content of organics in water body further declines, and turbidity slightly has after Filter column processing and 12h are stood
Decline is reduced by the soluble metal impurity content progress of representative of iron.
