Description
Technical field
A kind of water treatment facilities is the utility model is related to, is exactly a kind of multisection type disc tube reverse osmosis (dt-ro) system.
Background technology
Counter-infiltration (RO) technology is a kind of UF membrane of pressure differential using film both sides for rising in recent decades as motive force
Technology, disc tube reverse osmosis (dt-ro) (DTRO) are a kind of application forms of reverse osmosis technology, are specifically used to handle high-concentration sewage
Membrane module, its core technology are dish tubular membrane posts：Circular or octagonal reverse osmosis membrane and flow guiding disc and membrane module are stacked
Together, fixed by center pull rod and end plate, then inserted in pressure jacket, just form a disc tube reverse osmosis (dt-ro) film post.
It is easy when handling high COD, high concentrtion, high salinity waste water that disc tube reverse osmosis (dt-ro) overcomes general counter-infiltration system
The shortcomings that blocking, it can make that system is more stable, operating cost is lower.The service life of disc tube reverse osmosis (dt-ro) film post is three
More than year.
Under certain condition of water quality, the aquifer yield (i.e. membrane flux) of per membrane area necessarily, and every film cylinder product one
It is fixed, to realize certain production Water Sproading rate, it is necessary to be equipped with the film post of respective numbers.In disc tube reverse osmosis (dt-ro) system operation
In, to prevent calcium ions and magnesium ions in waste water and other pollutants to be attached to film surface, cause film to block, this requires waste water in film
The flow control on surface is within the specific limits (i.e. every film per hour inflow within the specific limits).
To ensure the normal operation of membranous system, a kind of original processing mode is that membranous system is divided into two sections, first paragraph film
The quantity of post handles water according to system and determines that remaining film post is as second segment system.First paragraph film post is by high pressure water supplying pump, production
Water enters water producing tank through water production pipeline, and concentrated water enters second segment film column system through concentrated water pipeline, because waste water passes through dish tubular membrane
After component, the loss of its concentrated water end pressure is about 8-12bar, therefore need to set inter-section booster in second segment film column system water inlet end
To supplement the pressure of membranous system loss.Simultaneously as film post needs certain flow of inlet water, and the concentrated water end of first paragraph film post is flowed
Amount is not enough to the flow of inlet water for reaching second segment film column system needs, therefore sets concentrate recirculation at second segment membranous system concentrated water end
Valve, a part of concentrate recirculation is set to supplement the water required for second segment film column system to before inter-section booster, pass through intersegmental increasing
Membranous system is again introduced into after the pressure of press pump supplement loss, carries out multiple membrane filtration processing, is returned with the system production water for realizing higher
Yield.
The problem of above-mentioned film post method of salary distribution is present be：Two sections of film post quantity are uneven, and second segment film post quantity is more, and the
One section of film column system is smaller, and the processing of first paragraph film post is raw water, and water quality treatment situation is better than second segment film post, and this just holds
It is easily caused first paragraph film post permeant flux and is higher than design load, and a fairly large number of second segment film column system permeant flux is then less than setting
Evaluation, actual motion is caused to produce situation about deviateing with design value.And because a fairly large number of second segment system of film post supplies
Wetting system only has an online booster pump, and this also easily causes, and water branch inside second segment membranous system is uneven, and pollutant is easy
Being deposited on the less film surface of amount of inlet water causes film to block, and causes the frequent clean of membranous system.
