Description
Technical field
The present invention relates to a kind of short route processing system suitable for rainwater reuse, belong to rainwater treatment field.
Background technology
Rainwater can be used for the low user of part water quality requirement after collection is handled, therefore rainwater-collecting reuse is to solve city
One of the effective way that city's city water resource lacks, while be also the important content of sponge urban construction.Rainwater-collecting reuse
Purposes be mainly used in greening pour spill, road and square flushing, garage floor flushing, vehicle wash, recirculated cooling water moisturizing, landscape
Water body moisturizing and flush the toilet.Rainwater reuse generally uses the handling process of coagulating sedimentation+filtering+sterilization, and the rainwater that will be collected converges
Enter rainwater collection pool, then add flocculant, precipitated in coagulative precipitation tank, water is after filter or filter after precipitation
Into rainwater reuse pond, forced feed user uses after then sterilizing, and wherein coagulating sedimentation is time-consuming longer, and the coagulation built
Sedimentation basin volume is big, and cost is high, due to the discontinuity of rainwater, in actual moving process, and coagulation sinks in the set handling process
Forming sediment, it is time-consuming longer to start, and flocculant consumption is larger, therefore operation and maintenance cost is higher, and it is difficult that part is completed rainwater recycling system
Normally to run.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of short route processing system suitable for rainwater reuse, drop
The investment of low rainwater recycling system and its operating cost.
To achieve these goals, technical scheme is as follows：A kind of short route suitable for rainwater reuse is handled
System, it is characterised in that：It is detained facility including biology, rainwater imports biological delay facility after collection, and the biology, which is detained, to be set
The bottom discharge pipe applied is connected with rainwater collection pool, and the outlet pipe of the rainwater collection pool is connected with the import of tube mixer,
Flocculant import, the water out of the tube mixer and the water inlet of filter-press are additionally provided with the tube mixer
It is connected, filter packing is provided with the middle part of the filter-press, water goes out after filter packing from the outlet of filter-press
To enter rainwater reuse pond, the outlet pipe in the rainwater reuse pond is connected with the import of ultraviolet ray disinfector, and the ultraviolet disappears
The outlet of malicious device is connected with rainwater reuse pipe network.
Using such scheme, rainwater flows into rainwater collection by the biological soil horizon filtering for being detained facility, water after filter by gravity
Collect in pond and store, after the filtering of biological delay facility, concentration of suspension is relatively low in rainwater, and then rainwater is in tubular-mix
Mixed in device with flocculant, forming tiny flco in water after mixing is directly entered filter-press filtering, and water after filter is through ultraviolet
Line sterilizer is sterilized, then up to standard to deliver to rainwater reuse pipe network.The system eliminates flocculation sedimentation tank, employs biological delay and sets
+ the mode that is combined of micro flocculating filter is applied, handling process is simplified, shortens process cycle, the fortune of rainwater recycling system can be improved
Row reliability, reduces investment and its operating cost of rainwater recycling system.
In such scheme：Water pump is provided between the rainwater collection pool and tube mixer, it is ensured that filter-press
Filter pressure, water pump is also equipped between the rainwater reuse pond and ultraviolet ray disinfector.Ensure that water passes through in ultraviolet sterilizer
Supplied water after sterilization using overbottom pressure by Storm Sewer Network to rainwater user.
In such scheme：Filter leaching material uses average grain diameter for 2mm quartz sand homogeneous filtering material, 15~20m/h of filtering velocity,
1.5~2.0m of depth of packing.Quartz sand uses average grain diameter for 2mm homogeneous filtering material, can improve the porosity of filtrate, filtering velocity is set
Be set to 15~20m/h, flco can be brought into filtrate depths, in-depth filtration is realized, both combinations can improve filtrate 20~
40% retaining power.Simultaneously to ensure water after filter effect, thickness of filter bed answers 1.5~2.0m, and delivery turbidity can reach 1~
3NTU, meets rainwater reuse requirement.
In such scheme：Flocculant uses polyaluminium sulfate, and dosage is 1~3mg/L.
In such scheme：The soil horizon that biology is detained facility uses planting soil, 0.5~1.0m of thickness.Pass through this spline filter
Afterwards, rainwater better quality out.
Beneficial effect：The short route processing system suitable for rainwater reuse of the present invention, is short route rain processing system,
In the case where meeting quality of reused water, greatly simplified handling process needed for rainwater reuse improves the reliability of system, and
Sponge urban construction demand, the investment of reduction rainwater recycling system and its operating cost are organically combined.
