Description
Technical field
The present invention relates to the in situ regeneration method of polluted filtering material in a kind of all water circulation systems or the water treatment system; relate in particular to a kind of in situ regeneration method that is used for industry water treatment systems such as Ferrous Metallurgy, petrochemical industry, generating, papermaking or water circulation system polluted filtering material, the method is of value to the environmental protection and the ecological balance.
Background technology
The handling problem of the filter in enterprise such as Ferrous Metallurgy or petrochemical industry or generating, papermaking water treatment system or the water circulation system (pond) polluted filtering material is being perplexed gently always, the development and the existence of heavy industry, after using one section, filter (pond) needs backwash, but greasy filth dirt composition complexity, strong adhesion because of contaminated filtrate adhesion, the backwash effect is not good enough, makes the water yield and the effluent characteristics of filter (pond) not reach production requirement.In order to solve this difficult problem, one of least responsible way is contaminated filtrate in the filter (pond) to be drawn (digging) go out to discard in the strange land, becomes industrial refuse, pollutes.
The foreign oil industry adopts " pump is washed formula " filtrate treatment technology to replace " stirring-type " filtrate processing mode from the eighties in last century, filtrate is carried out backwash handle." pump is washed formula " technology comparative maturity was domesticly introduced this technology in 1989, but this technology is only applicable to the processing of oil field walnut shell filtering material, and its processing mode is divided into two kinds by its structure difference: outer circulation mode and inner loop mode.The outer circulation mode is a kind of " displacement " processing method, and this method utilization liquefaction pump is sent walnut shell filtering material into the outer Scrubbing apparatus of filter body, to the filtrate processing of regenerating, then filtrate is sent into filter, discharges greasy dirt simultaneously.Be characterized in that filtration device structure is simple, be convenient to make, but increased pipeline and attached valve member, make the system pipeline complexity, increased the difficulty of control system, increased whole investment, if control bad, be easy to cause the migration of filtrate between filter, directly influence filters out water quality.Inner loop mode also is a kind of " displacement " processing method, and its utilizes liquefaction pump that walnut shell filtering material is sent in the Scrubbing apparatus in the filter, directly finishes the processing to filtrate in filter.The characteristics of this endless form are that backwash is abundant, and equipment mainly is made up of tank body, motor, liquefaction pump, Scrubbing apparatus and manifold, valve member etc.In Scrubbing apparatus when work,, oil-containing and impure filtrate enter Scrubbing apparatus from tangential direction under the effect of high-velocity flow, and high velocity impact friction in the inner small space of Scrubbing apparatus reaches the purpose of backwash " regeneration ".
Once the relevant report of handling relevant for the filtrate of getting dirty because of interior petroleum industry, but it mainly uses chemical method to finish, and must transform existing equipment, even need to change original filter.Before the present invention, it is investigated that 1. publication number is CN1772859A " filter material in oil field sewage filtering tank regeneration cleaning agent and a regeneration washing process ", it is the method that the contaminated filtrate of a kind of petroleum industry adopts displacement regeneration to handle; What 2. publication number was that CN1672770A " sewage water filtration jar useless filtrate reclaim cleaning " relates to is the recovery cleaning that useless filtrate adopts displacement regeneration to handle in the oil recovery field, a kind of oil field.
The employed processing mode of home and overseas all must discarded existing filter plant, and new equipment is installed, and these two kinds of processing modes still use cleaning agent that filtrate is carried out chemical washing, still can't remove the greasy filth of filtrate filter intragranular portion.
Both at home and abroad the filtrate in the steel industry filter (pond) mostly is the cleaned coal filtrate, and the filtrate after contaminated is continued to use back-washing method always and carried out halfway processing, and filtrate promptly loses filter capacity after a period of time, have to periodically more renew filtrate.Point out according to " scientific and technological novelty assessment report " that the Scientific and Technical Information Institute, Hunan Province provided on December 17th, 2007: " not looking into identical steel industry water treatment system filtrate in-situ regeneration technical research of new projects' complex art feature and the reported in literature of applying both at home and abroad at present " with this.
