Abstract
The invention discloses a kind of method that drainage is grouped by standalone module, this method improves to some extent in validity and in terms of reducing pollution.From accessing pending water supply lines via at least one accessing pending water entrance accessing pending water is supplied to each filtering module, via filtrate (liquid filtrate is removed from each filtering module, wherein, the filtering module is cleaned by means of the back flush using filtrate, wherein, filtering module is divided into group, during back flush, each group is independently separated with accessing pending water supply lines, and rinses the group using being produced by other groups and the filtrate of supply being reversed during back flush.
Description
Technical field
The present invention relates to a kind of water filtration method, more particularly to a kind of method that drainage is grouped by standalone module.
Background technology
At present, hyperfiltration system is built in a variety of manners, but filter method is generally carried out in a similar manner, that is, is produced
Filtrate (filtrate) (be free from germs as far as possible, bacterium and virus) be collected in batch bucket/temporary container, and from this
Place is sucked to user.Water needed for the back flush (backwashing) of hyperfiltration module and CIP (cleaning on the spot) is also derived from
At this.The danger that the operating method is present is：On the one hand, undissolved composition may be via the change used during CIP
Product reach beyond the filtrate side of filter.On the other hand, in back flush procedure, microbial impurities may be via filtrate from filtrate
Bucket itself reaches filtrate side.The removal of these pollutants is a problem, particularly in so-called hollow fibre filtering module-
In the case of outer method (filter operation from inside to outside).Another shortcoming is：During back flush, due to using same
Circuit, it is thus impossible to produce filtrate.
The content of the invention
General object of the present invention is to provide the filter method of effective work for handling water, to overcome prior art
It is not enough.
The present invention is achieved in that a kind of method that drainage is grouped by standalone module, utilizes multiple independent filter modules
Block carrys out filter water, is supplied from accessing pending water supply lines via at least one accessing pending water entrance to each filtering module pending
Water, filtrate is removed via filtrate (liquid from each filtering module, wherein, the mistake is cleaned by means of the back flush using filtrate
Module is filtered, the water filtration method is characterised by that the filtering module is divided into group, during back flush, and each group is only
On the spot separated with the accessing pending water supply lines, and utilization is produced by other groups and supply is reversed during back flush
Filtrate rinse the group；A kind of filtration system, especially more than filter system, it, which has, is used to carry out back flush using filtrate
Back flush apparatus and multiple independent filtering modules, the filtering module, which is respectively provided with, is connected to accessing pending water circuit extremely
A few accessing pending water entrance collects a filtrate (liquid of circuit and reverse for being carried out using filtrate with filtrate is connected to
The back flush apparatus of flushing, the filtration system is characterised by that the filtering module is divided into group, wherein, the equal energy of each group
It is enough independently of other groups being separated with the accessing pending water circuit.
Optionally, the present invention allows to carry out CIP from accessing pending water side.So, each group just can individually carry out CIP, disappear
Except chemicals is to the pollution for the filtrate discharged.
The present invention research and development allow to rinse each filtering module in the state of production process continuous service, from without
Close whole system.In addition, carrying out back flush by the filtrate from ongoing production process so that Bu Hui
Inevitable storage time produces pollutant or growth microorganism.
Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, with reference to embodiment
The present invention is further detailed explanation.
A kind of method that drainage is grouped by standalone module, using multiple independent filtering modules come filter water, from pending
Water supply lines supply accessing pending water via at least one accessing pending water entrance to each filtering module, via filtrate (liquid from each mistake
Filter module and remove filtrate, wherein, the filtering module, the water filtration method are cleaned by means of the back flush using filtrate
It is characterised by, the filtering module is divided into group, during back flush, each group is independently supplied with the accessing pending water
Circuit is separated, and rinses the group using being produced by other groups and the filtrate of supply being reversed during back flush；It is a kind of
Filtration system, especially more than filter system, it, which has, is used to utilize the filtrate progress back flush apparatus of back flush and many
Individual independent filtering module, the filtering module be respectively provided be connected to accessing pending water circuit at least one accessing pending water entrance and
It is connected to filtrate and collects a filtrate (liquid of circuit and the back flush apparatus for carrying out back flush using filtrate, institute
State filtration system to be characterised by, the filtering module is divided into group, wherein, each group can independently of other groups with it is described
Accessing pending water circuit is separated.
The present invention research and development allow to rinse each filtering module in the state of production process continuous service, from without
Close whole system.In addition, carrying out back flush by the filtrate from ongoing production process so that Bu Hui
Inevitable storage time produces pollutant or growth microorganism.
The further advantage of the present invention can be obtained by following feature：During the back flush of a group, increase by other
The amount for the filtrate that group is produced；The amount for the filtrate outwards flowed in all groups of downstream regulations；The amount of back flush liquid is conditioned；From
Accessing pending water side carries out CIP；The filtrate, which collects circuit, has the stopper in the downstream for being located at all groups, and the stopper is excellent
Elect regulating valve as；The wastewater treatment circuit for being connected to all filtering modules is provided with, configures and uses in the wastewater treatment circuit
The regulating valve of wastewater flow rate during back flush is adjusted；Controllable suction pump is arranged at accessing pending water suction inlet；CIP circuits lead to
To the accessing pending water circuit, preferably lead to the accessing pending water circuit in the upstream of prefilter-pump complex.
The embodiment of the present invention is described in detail above, specific case used herein to the principle of the present invention and
Embodiment is set forth, and the explanation of above example is only intended to the method and its core concept for helping to understand the present invention；Together
When, for those of ordinary skill in the art, according to the thought of the present invention, have in specific embodiments and applications
Change part, to sum up, this specification content should not be construed as limiting the invention.
Claims (2)
1. a kind of method that drainage is grouped by standalone module, using multiple independent filtering modules come filter water, from accessing pending water
Supply lines supply accessing pending water via at least one accessing pending water entrance to each filtering module, via filtrate (liquid from each filtering
Module removes filtrate, wherein, the filtering module is cleaned by means of the back flush using filtrate, the water filtration method
It is characterised by：The filtering module is divided into group, during back flush, each group independently with the accessing pending water supply line
Road is separated, and rinses the group using being produced by other groups and the filtrate of supply being reversed during back flush.
