To achieve these goals, the technical solution of the utility model：A kind of removal bitter and fishiness concentrated water utilization system,
It includes the one-level RO system concentrated water drainings in the cooling tower circulating water system of natural gas conversion methanol, removal bitter and fishiness
Mouthful and the hyperfiltration reverse-rinsing water outlet of backwash operation is carried out to ultrafilter, laminated filter respectively, laminated filter backwash water is arranged
Outlet, wherein, the one-level RO system concentrated waters discharge outlet, hyperfiltration reverse-rinsing water outlet, laminated filter backwash water outlet are equal
It is connected in a collection pond, the collection pond is communicated to circulating-water bypass filter tank, the circulating-water bypass filter tank and the cooling tower
Circulating water system is connected.
Further, there is inhibition dispersant input port on the circulating-water bypass filter tank.
Further, there is stirring system in the collection pond.
Further, the collection pond is connected by the delivery main provided with pipeline pump with the circulating-water bypass filter tank,
And there are several reserving valves on the delivery main.
Further, the reserving valve is DN20 or DN30 reserving valve.
Further, the inhibition dispersant input port includes NP4300 dispersants input port, ZP2002 corrosion inhibiter is put into
Mouth, CI2104 copper inhibitors input port, sulfuric acid input port.
Further, there is liquid level intelligent monitoring device in the collection pond, the liquid level intelligent monitoring device with it is described
The intelligent control end of pipeline pump is electrically connected with.
The beneficial effects of the utility model：Design science is reasonable, unifies back for the discharge of wastewater of removal bitter and fishiness
Receive and recycle, the scale inhibition for realizing one-level RO system concentrated waters by the antisludging agent remained in ultrafilter, laminated filter backwash water is imitated
Fruit, the auxiliary that both do not conflict mutually and formed on certain effect, then it is that can reach recirculated water to make to be added by some simple medicaments
With standard, and then circulation water use efficiency is improved, and reduce production cost, reach the purpose of water-saving and emission-reducing.
Brief description of the drawings
Fig. 1 is structural schematic block diagram of the present utility model.
Embodiment
The utility model is further described with reference to specific embodiment and accompanying drawing.
A kind of removal bitter and fishiness concentrated water utilization system as shown in Figure 1, it includes the cooling of natural gas conversion methanol
One-level RO system concentrated waters discharge outlet 11 in water tower circulating water system 10, removal bitter and fishiness and respectively to ultrafilter, lamination mistake
Filter carries out hyperfiltration reverse-rinsing water outlet 12, the laminated filter backwash water outlet 13 of backwash operation, wherein, one-level RO systems
Concentrated water discharge outlet 11, hyperfiltration reverse-rinsing water outlet 12, laminated filter backwash water outlet 13 are connected to a collection pond 20
In, the collection pond 20 is communicated to circulating-water bypass filter tank 30, the circulating-water bypass filter tank 30 and cooling tower circulating water system 10
It is connected.
It is one-level RO systems concentrated water that the utility model discharges one-level RO system concentrated waters discharge outlet 11 in removal bitter and fishiness, super
Filter backwash water outlet 12, the hyperfiltration reverse-rinsing water that laminated filter backwash water outlet 13 is discharged, laminated filter backwash water
Deng after the circulating water index for reaching cooling tower circulating water system 10 after processing, it to cooling tower circulate cold
Water moisturizing, and then water-saving and emission-reducing purpose is realized, circulation water use efficiency is improved, and production cost is reduced, and bring certain
Economic benefit, suitable popularization and application.
In the system, RO waste water is the result after industry water concentration, and recirculated cooling water is also the mistake for concentrating industry water
Journey, so it is feasible that RO waste water, which is filled into circulating water system, but both technological parameters are different, such as directly fill into RO waste water
In circulating water system, it will reduce the actual cycles of concentration of system.
Because removal bitter and fishiness can add antisludging agent during operation, so antisludging agent is had in RO waste water brings circulation into
In chilled water system, because the RO antisludging agents at scene are also the research of non-phosphorus scale inhibitor of use, so can't band to circulating water system
Carry out the negative effect in terms of EHS, RO scale inhibition principle and the scale inhibition principle of circulating water are consistent in addition, so RO resistances will not occur
The problem of dirty agent has an impact to circulating water treatment pharmacy effect.
Actual cycles of concentration, the increase of blowdown flow rate, corresponding water will be reduced because RO waste water enters circulating water system
Treatment agent amount can increase, therefore have inhibition dispersant input port 31 on circulating-water bypass filter tank 30, and the inhibition dispersant is thrown
Entrance 31 includes NP4300 dispersants input port, ZP2002 corrosion inhibiter input port, CI2104 copper inhibitors input port, sulfuric acid input
Mouthful, carry out that each formula is specific to be launched in practical application as the case may be, its spend cost than for the water resource of saving only
Very small part is only occupied, is economically calculated very much.
Collecting in pond 20 has stirring system, for by one-level RO concentrated waters, hyperfiltration reverse-rinsing water, laminated filter backwash water
Uniformly mixed.There is liquid level intelligent monitoring device, the liquid level intelligent monitoring device and the pipe in the collection pond 20
The intelligent control end of road pump is electrically connected with, to realize the automatic discharge water control between collection pond 20 and circulating-water bypass filter tank 30
System, and the intelligent control end of liquid level intelligent monitoring device and pipeline pump is prior art, its technical principle and circuit control knot
Structure is also prior art, is repeated herein without unnecessary.
In this example, collect pond 20 and be connected by the delivery main provided with pipeline pump with circulating-water bypass filter tank 30, and at this
There is several reserving valves for DN20 or DN30, so that greening and flusher ground are used on delivery main.
The technical scheme provided above the utility model embodiment is described in detail, used herein specifically
Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in embodiment and application, in summary, this specification content should not be construed as
To limitation of the present utility model.
